CUSTOM® tile installation sets standard of care at San Diego hospital

Critical care was taken with the design of Jacobs Medical Center, a 500,000-sq.-ft. specialty hospital in La Jolla, Calif. Construction specifications for this landmark project included a full system of CUSTOM® tile installation and flooring preparation products on all 12 floors. This cutting-edge medical center focuses on innovating complex procedures such as brain surgery and marrow transplants. To support its medical advances, the healing environment is filled with a cheering array of ceramic and glass tile precisely installed in patient bathrooms, public and staff areas, the kitchen and a welcoming cafeteria.

Tile installation 

Floors were leveled using a CustomTech™ system including premium quality TechLevel™ 150 Self-Leveling Underlayment.

The tile installation at Jacobs Medical Center began with surface preparation in accordance with industry standards. Wet areas, such as patient bathrooms and showers, were treated with liquid-applied RedGard® Waterproofing and Crack Prevention Membrane, which meets the requirements of ANSI A118.10 and A118.12. RedGard is a ready-to-use elastomeric membrane that creates an effective, continuous waterproofing barrier with outstanding adhesion to drain assemblies. A single coat of RedGard was also applied on floors in dry tiled areas to provide crack isolation up to 1/8”.

Two polymer-modified, cementitious mortars from CUSTOM’s established VersaBond family were used. VersaBond®-LFT Professional Large Format Tile Mortar was selected to install large format tile throughout the project. This includes 12” x 24” porcelain in patient bathrooms on all floors, plus 9” x 36” and 6” x 36” wood-look planks in the hospital cafeteria. VersaBond-LFT is a non-slumping mortar that can be applied as thick as 3/4” on horizontal applications to help prevent lippage issues common with large format tile. Kitchen quarry tile and 2” tile on shower floors were set with VersaBond® Flex Professional Thin-Set Mortar. VersaBond Flex is formulated for high bond strength and extended open time to allow for tile adjustment.

All wet areas were treated with liquid-applied RedGard® Waterproofing and Crack Prevention Membrane. RedGard exceeds ANSI A118.10, A118.12, IAPMO shower pan liner and TCNA low perm barrier standards.

Patient bathrooms and nursing stations on each floor received one of three different color schemes with 3/4” x 3/4” glass mosaic wall tile in shades of green, blue and peach. Public restrooms were tiled in a dramatic black-and-white pattern with 1/2” by 1/2” ceramic mosaics. Specifications designated wall tile installation throughout the project with ProLite® Premium Large Format Tile Mortar. ProLite offers non-sag performance on walls along with excellent handling characteristics, making it an installer favorite. This versatile mortar also exceeds ANSI A118.4TE, A118.15TE and A118.11 standards for demanding installations. ProLite is formulated with lightweight, recycled aggregate, so it weighs 40% less than other mortars. This makes ProLite easier to carry, mix and apply than other mortars while also making projects eligible for LEED points.

VersaBond®-LFT Professional Large Format Tile Mortar was selected to install large format tile throughout the project. VersaBond-LFT is a non-slumping mortar that can be applied as thick as 3/4″ on horizontal applications to help prevent lippage issues common with large-format tile.

“Out of all the mortars we have used over the years, our installers like CUSTOM’s ProLite the best,” said Gary Rodocker, superintendant at Inland Pacific Tile.

CEG-Lite™ 100% Solids Commercial Epoxy Grout was specified on all floors and walls for chemical and stain resistance in a clinical environment.

For chemical and stain resistance in a clinical environment, CEG-Lite™ 100% Solids Commercial Epoxy Grout was specified for use on all floor and wall tile. CEG-Lite is easier to spread than typical epoxy grouts, cleans up with only water and contributes towards LEED certification. This grout exceeds the performance requirements of ANSI A118.3 and is suitable for vertical grout joints without an additive. Movement joints were treated with CUSTOM’s Commercial 100% Silicone Sealant to remain flexible and protect the assembly in accordance with TCNA Handbook detail EJ 171.

CUSTOM manufactures all of its grouts and sealants in an array of 40 designer-inspired colors and many of the shades were used to match the nuanced tile palette at Jacobs Medical Center. The extensive ceramic, glass and large format porcelain tile set throughout the hospital was supplied by Daltile.

Wall tile throughout the project was installed with ProLite® Premium Large Format Tile Mortar. ProLite offers superior handling and non-sag, thixotropic performance. It’s ideal for hard-to-bond tile like glass.

“We are very satisfied with the performance of the products and the support of the staff at CUSTOM,” said Dann Salinas, senior estimator and project manager at Premier Tile & Marble. “The Technical Services team was very responsive and attentive to our needs during all phases of the project.”

Flooring preparation

Prior to installation of floor coverings, substrates at Jacobs Medical Center were prepared with a CustomTech™ underlayment system. The Rouse Company addressed floor flatness on 330,000 sq. ft. of concrete slabs including corridors, laboratories and patient care areas.

TechPrime™ A Advanced Acrylic Primer was used to seal the surface and improve the bond of the calcium aluminate-based underlayment. After just an hour of dry time for the primer, the installation team poured TechLevel™ 150 Self-Leveling Underlayment up to 1-1/2” deep. Premium quality TechLevel 150 achieves greater than 4,300 psi compressive strength to resist point load, which is important given the weight of hospital equipment.

Many of the patient room showers feature curbless access, highlighting the importance of using RedGard® Waterproofing and Crack Prevention Membrane, a liquid barrier offering seamless, monolithic coverage.

“TechLevel 150 is my go-to leveler if I have a choice,” said Josh Reed, concrete division manager at the Rouse Company. “We definitely prefer it over any other product and use it on all of our jobs. The entire CustomTech flooring prep system is easy to use and works great. We love it!”

CUSTOM tile installation and flooring preparation systems were selected on the basis of rigorous product standards, unparalleled technical support and quality backed by an extended warranty. The high-use, high-traffic tile assemblies at Jacobs Medical Center qualified for a 15-year installation system warranty. Two lightweight Emerald Systems™ formulas included in the installation, ProLite and CEG-Lite, can also earn carbon offset credits for any project where they are installed.

1/2” mosaics in various black and white patterns give a dramatic yet timeless look to the public restrooms. Tile throughout the hospital was supplied by Daltile.

A project of this scope and scale called for a team with extensive expertise in hospital construction, led by architects Cannon Design and executed by general contractor Kitchell Contractors. Commercial flooring specialist, The Rouse Company applied a CustomTech™ flooring-preparation system. Tile contractors on the job included Premier Tile & Marble, who set the tile on floors B1, lower level and 1-3, and Inland Pacific Tile, installers for floors 4-10. Architectural and technical representatives from CUSTOM assisted the designers and contractors during each phase of the construction.

Kitchen quarry tile was set with VersaBond® Flex Professional Thin-Set Mortar, which is formulated for high bond strength and extended adjustment time.

“Jacobs Medical Center is a showcase facility that joins the rapidly-growing ranks of impressive projects specifying Custom Building Products,” said John Diaz, commercial architectural coordinator with CUSTOM. Jacobs Medical Center is owned and operated by UC San Diego Health in La Jolla, Calif.

9″ x 36″ and 6″ x 36″ porcelain wood-look planks were set in the hospital cafeteria and dining room using non-slumping VersaBond®-LFT Professional Large Format Tile Mortar.

Jerome L. Greene Neuroscience Center: building for scientific progress

MAPEI products used in award-winning project

The Jerome L. Green Neuroscience Center at the Manhattanville campus of Columbia University in New York City was built to take us into new frontiers of medicine. According to the University, “At the Jerome L. Greene Science Center, hundreds of the world’s leading researchers will tackle the most exciting scientific challenge of our time: understanding how the brain works and gives rise to mind and behavior.”

Housed within the Greene Science Center, the Zuckerman Mind Brain Behavior Institute brings together nearly 1,000 scientists from across many departments at Columbia University who will collaborate on research, teaching and public programming. Their goal is a deeper understanding of the brain that promises to transform human health and society.

Floors covered with Mapeguard 2.

From effective treatments for disorders like Alzheimer’s and Parkinson’s to depression and autism, the potential impact for humanity is enormous. “Just as science was transformed in the 20th century by the decoding of DNA, science in the 21st century will be transformed by decoding the human brain,” said Eric Kandel, MD, co-director of the Zuckerman Institute.

The Greene Science Center is the first of several buildings to be completed on the Manhattanville campus. The University press office reported, “The nine-story, 450,000-sq.-ft. [41,806 m2]

Unique tile-to-metal stair installation.

structure is the largest that Columbia has ever built and the biggest academic science building in New York City.” Designed by the world-renowned Renzo Piano Building Workshop, in association with Davis Brody, LLP, and Body Lawson Associates of New York, the science center has led us to expect great things of its construction. In fact, the center won the Ceramics of Italy 2017 Tile Design Competition in the Institutional category.

MAPEI at work on the jobsite

Jantile, Inc., of Armonk, N.Y., won the bid to install the ceramic tile throughout the project. As always, coordination with other trades played a role in the installation, but thanks to general contractor Lend-Lease, with whom Jantile frequently works, all went smoothly.

Tiles set with Ultraflex LFT and grouted with Ultracolor Plus.

The main challenge dealt with accurate transitions from space to space. Because the Jantile crew was working with such large tiles over vast expanses of open space, and because the glass facades shed so much light on the space, the installers had to be exceptionally careful lining up tiles with each other and other surfaces on each of the eight levels.

Lots of light meant exacting transitions.

The first and largest component of the project for Jantile was the preparation of the space prior to setting tile. The core structure of the building is steel with a glass facade for the shell. Because the subsurface was steel, each of the eight upper floors had to be prepared with a mud bed measuring 2.5” (6,3 cm) in thickness. First, the crews put down a slip sheet and covered it with mud and wire reinforcement. The installation crews then combined MAPEI’s Planicrete® AC, a liquid latex admixture, with the mud bed mix to enhance its performance.

Once the mud bed cured, it was covered with MAPEI SM Primer™ and Mapeguard™ 2, a thin, lightweight crack-isolation and sound-reduction sheet membrane. Mapelastic™ 400 was also used for waterproofing in the restrooms.

Wide open expanses of tile.

Casalgrande Padana tile was installed over 78,000 sq. ft. (7,246 m2) of space on the upper eight levels of the nine-story building. In the corridors and open expanses, MAPEI’s Ultraflex™ LFT™ mortar and Ultracolor® Plus grout were used to install 40,000 sq. ft. (3,716 m2) of Pietre etrusche capalbio tiles from Casalgrande Padana’s Pietra Native Series measuring 24” x 48” (61 x 122 cm) and 18” x 36” (46 x 91 cm). An additional 38,000 sq. ft. (3,530 m2) of 12” x 24” (30 x 61 cm) floor tiles and 12” x 12” (30 x 30 cm) wall tiles from the Pietra Native series were set in public restrooms in the building. Once again, the setting materials were Ultraflex LFT and Ultracolor Plus. A custom mix of mosaic tiles from Vitra were used as a decorative feature in the restrooms, also set with the MAPEI products. All tiles and installation products were provided by MAPEI distributor ProSpec, LLC.

The installers worked from shop drawings that had been approved by the architects. The work in the restrooms took one to two months, and was done intermittently as each floor became ready. The large, open expanses were completed over a continuous six-month period. When restrooms and floor expanses were ready at the same time, eight to 12 Jantile installers worked the site.

One particularly interesting and unique challenge was met with a series of MAPEI products. The metal stairways connecting each floor were designed to be covered with the large-format Casalgrande Padana tiles. To get the ultimate bond between the ceramic tiles and metal stairs, the installers began by coating the metal surface with Primer E 100%-solids epoxy primer to enhance the bond with Mapecem Premix cement-based mortar for subfloor preparation work, which was layered on top of it. The tiles were then set into the Mapecem® Premix using Ultraflex LFT.

Project manager Don Durnell summed up this fascinating but challenging installation: “Coordination by experienced people throughout the entire process is what allowed us to accomplish this feat. We depended on the experience and expertise of our long-time employees to get the job done right.”

MAPEI is proud to have been a part of the job.

From the top of the mountains, all the way out into the ocean, every aspect of life in the Kingdom of Hawaii aims to be synergistic and sustainable, including its residential communities. With the goal of becoming the largest LEED for Neighborhood Development Platinum (LEED-NP) certified community in the country, building owner Howard Hughes Corporation hired James K.M. Cheng in collaboration with Rob Iopa and WCIT Architecture to design Waiea Tower, the flagship building of what is to be Honolulu’s most distinguished neighborhood, Ward Village.

The 60-acre coastal master planned community allows for up to 9.3 million square feet (approximately 863,998 m2) of mixed-use development and offers numerous outdoor gathering spaces that embrace Hawaiian culture, the perfect mix of urban and eco-friendly living. At completion, the community will include more than 4,000 residences and over one million square feet (92,903 m2) of retail shopping. To complete the construction of the 36-story tower, BMK Construction was enlisted to handle the tile and flooring installations for all of Waiea’s units and public spaces including the pool deck, level one lobby, porte cochere and four levels of penthouses.

“The Waiea Tower represents a level of architectural sophistication never before available in Hawaii, so it was exciting to be a part of history,” said BMK Construction project manager Kent Amshoff. “With the design team utilizing only the highest luxury elements, BMK Construction chose to use a range of LATICRETE® products to ensure long-lasting, quality installations that were also good for the environment.”

For centuries, water has been one of the most treasured resources of the Hawaiian people. As is typical of the entire community’s tie to Hawaiian culture and history, Waiea’s design pays homage to the Hawaiian term for “water of life” that links the structure to the importance of water in Hawaii’s coastal landscape.

Logistical Procurement: High-end design materials from around the world were brought in from countries such as Italy, Portugal, China, Kenya, Turkey and the U.S. mainland. This proved challenging to assure proper quantities and specifications of each product would be delivered in time for installation.

Quality Control: Maintaining stringent levels of quality was a major concern during construction as multiple delays occurred due to massive rain storms in the summer of 2016. This mostly affected the installation of the pool deck, as contractors were not able to perform duties outside. Additionally, due to the high-end design elements, such as custom marble walls in the penthouse bathrooms, all plumbing work and leveling work needed to be performed with precision, as there would not be a second chance to get the installation right.

A LATICRETE solution:

To meet the goal of acquiring LEED certification, all LATICRETE products chosen for the construction of Waiea Tower were those that have received multiple certifications and declarations including Health Product Declarations (HPD), Environmental Product Declarations (EPD) and UL GREENGUARD Gold Certifications for low chemical emissions.

“LATICRETE is currently the only company with a full product-specific EPD for its cement self-leveling underlayments, cement grouts and cement mortars that includes both 255 MULTIMAX and PERMACOLOR® Grout,” said Amshoff. “These certifications gave Howard Hughes Corporation the peace of mind that LATICRETE is on the leading edge of sustainable innovation by providing transparency about the life-cycle impacts of their products.”

To set all tile, BMK Construction used 255 MULTIMAX as a large-and-heavy-tile adhesive mortar. The patented, versatile polymer-modified thin-set was chosen due to its exceptional non-sag performance on walls, build up of 3/4” (18 mm) without shrinkage for floors, and maximum coverage due to its lightweight, creamy and smooth consistency. In addition, 255 MULTIMAX is reinforced with Kevlar® to provide maximum strength and durability, and now contains less than 10% post-consumer recycled content.

For waterproofing bathrooms throughout the entire building, including the 500 square feet (46 m2) of penthouse master bathrooms’ showers and toiletry areas, BMK Construction used HYDRO BAN® as a thin, load-bearing waterproofing/crack-isolation membrane. Thanks to its “Extra Heavy Service” rating per TCNA performance levels (RE: ASTM C627 Robinson Floor Test), HYDRO BAN was able to support even the heaviest materials, including Jade Green Onyx, which is seen in the 36th floor penthouse shower.

3701 Fortified Mortar thick-bed mortar was used to slope the showers, baths and pool deck to the area drains. Additionally, 3701 Fortified Mortar was used on the drive line where granite paver stones were present and applied on top of HYDRO BAN for the installation of structural concrete slabs. Chosen for its ease of use, 3701 Fortified Mortar is a polymer-fortified blend of carefully selected polymers, Portland cement and graded aggregates that does not require the use of latex admix. Water is the only element needed to produce thick-bed mortar with exceptional strength.

To grout, PERMACOLOR Grout was used for its high-performance properties, which provide a grout joint that is dense, hard and will resist cracking. Additional benefits include consistent color, fast setting and improved stain resistance for a cement-based grout.

Outcome

“With the help of LATICRETE, Ward Village is now the largest LEED-ND Platinum certified development in the country,” said Amshoff. “This building is at the forefront of sustainable development and solidifies the LATICRETE commitment to environmental responsibility.”  Waiea, the first completed residential tower, welcomed its first residents and anchor tenant Nobu in late 2016. Three high-rise residential buildings are currently under construction – Anaha, Ae‘o and Ke Kilhoana – and will be home to internationally acclaimed brands such as Merriman’s Restaurant and a flagship Whole Foods Market®.

In a project where luxurious sophistication is the name of the game, each and every detail, no matter how large or small, makes all the difference in the final presentation. The Sagamore Pendry Baltimore – of premier hospitality brand Pendry Hotels – is the newest hot spot for luxury travel and indulgence in Baltimore’s historic yet newly renovated Fell’s Point neighborhood. Developed in collaboration between Montage International and Sagamore Development Company, the hotel boasts 128 luxury guestrooms and suites and several glamorous restaurants, lounges and bars. From the American Industrial Age-themed murals and décor, to the Grand Ballroom with sky-high ceilings, to the visionary choice and placement of stone tiles throughout the building, each unique detail of the Pendry Baltimore denotes and delivers a story and vision.

Flair and functionality come together

The impressive interior style combines sophisticated, inspired design reminiscent of the city’s rich industrial heritage with a modern, edgy perspective; juxtaposing rich, warm wood with eye-catching, cool stone furnishings throughout and complemented by unique American accent pieces. Designed by architect and Baltimore’s own Patrick Sutton, the Pendry Baltimore sets the standard for the melding of both new and vintage styles. The stone installations throughout the building perfectly match this high-class, world traveler aesthetic, as each piece was masterfully chosen and strategically placed for an extra touch of glamour and ensured functionality.

When NTCA Five Star Contractor Profast Commercial Flooring was approached by Whiting-Turner General Contractors to supply the cost-efficient, high-performing materials they wanted from around the world, Profast president Kevin Killian knew they’d need a trusted and top-quality waterproofing system to ensure a job well done. Upon reviewing the scope of the project, all answers pointed definitively to Merkrete, the leader in waterproofing, crack-isolation and underlayment technology. The expertly chosen stone tiles grace the hotel’s grand lobby floors, every guest bathroom on the shower walls, shower floors, shower curbs, stone base, stone flooring and stone backsplash, along with the restaurant and bar floors, interior and exterior fireplaces and public bathrooms. To prevent any potential moisture issues in such highly utilized areas, Merkrete’s trusted system won them the contract. 

A versatile solution seals the deal

When it comes to the critical waterproofing under tile in the stone-clad bathrooms, guest and public, Merkrete’s BFP waterproofing membrane system was the only solution. Durable and long lasting, this membrane system is designed for heavy-duty applications, promising zero leaks or cracks, even with severe exposure and high amounts of traffic.

Because of the size of the showers in the guest bathrooms, Killian needed a versatile product that could address several specific needs at the same time: a pre-mixed product that could be used to form the shower pans while also repairing imperfections in the floors. Merkrete’s sales representative on the job, Chris Zampella, said, “I immediately knew that Merkrete’s Underlay C was the perfect product for these requirements. Its versatility allows you to build up to 3” and spread to almost a feather edge (1/8”). You don’t usually get that in a single product.”

Merkrete proved the perfect match for a specific challenge, again considering the strength of the mortar it called for. “We used very large stone panels, which require a mortar with a super high bondability that can handle the weight of the panels,” said Killian. Merkrete 855 XXL is a one-step, polymer-modified setting adhesive for installing extra-large-format porcelain, ceramic tile and natural stone for both floors and walls, and can be used as thin- or medium-bed setting adhesive for stone. Merkrete proved it could hold its weight.

In addition to the waterproofing membrane system the hotel required, Merkrete was the trusted source yet again in providing high-performance, sustainable grout in the lobby and bar floors. “Merkrete’s ProGrout is a fast-setting, polymer-modified, color-consistent and efflorescence-free high performance grout that exceeds ANSI A118.7 for all types of ceramic and dimensional stone tiles on walls and floors,” said Zampella. “It works for grout joint widths of 1/16” up to 1/2” wide, eliminating the need for different grout products and allowing Kevin the versatility he required.”

Part of the challenge in this project involved the fast-track timeline. Installation began in June 2016 and was completed by November 2016. It was critical that Killian chose a company that would be able to get the products delivered and the job completed on time. Merkrete is a member of ParexGroup, one of the largest companies and a worldwide leader in tile setting materials, façade finishes and technical mortars, established in 22 countries with 68 manufacturing plants and over 4,100 employees. “Merkrete was perfect for this project’s requirements, because we have plants and distribution centers all over the country, so our turnaround time and ability to get our products there quickly were no problem,” says Zampella.

With the Pendry Baltimore having just recently celebrated its grand opening, the guests have flooded in to experience the fine culinary offerings while embracing the idyllic harbor setting and incredible architecture. In the years to come, more renovations may take place, but thanks to Merkrete, you can be sure the stone tiles will be standing strong.
