January 2018 Feature Story – MAPEI
Anaha® (which means “reflection of light” in Hawaiian) is a magnificent new condominium complex on the island of Oahu. Made of concrete, glass and steel, it is part of the Ward Village master-planned community near Kewalo Harbor in Honolulu. This new luxury high-rise was planned by Howard Hughes Corporation and designed by architects Solomon Cordwell Buenz of Chicago and Ben Woo Architects of Honolulu. The interiors were designed by global design leader Woods Bagot Interiors.
The complex is composed of the Anaha Tower, housing eight residences per floor plus penthouses on Levels 36-38, as well as the Podium townhouses and flats, which occupy the first six floors and extend from the tower. The roof of the Podium (adjacent to the seventh floor of the tower) hosts an amazing selection of indoor and outdoor activity areas, including a cantilevered pool that extends 13 feet beyond the building’s edge and features a glass bottom.
The LEED Platinum building was designed with the environment in mind – harmonizing with sea, sky and mountains. The exterior of the entrance area sports a “living wall” of plants and water elements framed with lava stone veneer that surround tile walkways forming the signature “W” for Ward Village. The interior of Anaha is just as awe-inspiring, with floor-to-ceiling windows that open every residence to views of the Pacific Ocean or the Honolulu skyline. Some expanses even look out toward the historic Diamond Head landmark.
Floor and wall coverings received all manner of treatments, including stone and stone veneer in public areas indoors and out; (at the owner’s option) carpet, wood and tile in living spaces; stone and tile in bathrooms of the residences; and resilient floor coverings in service areas.
The Hawaii branch of A-American Custom
Flooring, Inc. (a member of the Tile Contractors Association of Hawaii), was in charge of all aspects of the tile installations for interior and exterior walls, floors and specialty elements with the exception of the interior tile walls of the pool on the amenities deck. Their installers also handled moisture mitigation work and installation of wood, carpet and resilient floor coverings. A-American worked closely with General Contractor A. C. Kobayashi, Inc., to complete all the aspects of the installations on schedule, including the mega-challenge of zero tolerance in transitions between flooring types.
Zero tolerance transitions moisture mitigation and waterproofing
Anaha’s 236-unit residence tower and 81 townhomes and flats were architecturally designed with a zero tolerance scheme for all finishes in the flooring landscape of the building. From interior to exterior, zero tolerance requirements meant that all transitions could hold no change in height from tile to wood to carpet to resilients, to respect accessibility for disabled persons according to the Americans with Disabilities Act (ADA).
This zero tolerance created building and flooring challenges that were met by a wide variety of MAPEI’s concrete repair and flooring installation systems products for construction, surface preparation and floor-covering solutions. The fast-track schedule of the 38-story tower and the six-story podium required coordination and solutions for arising jobsite problems involving moisture mitigation and slab deformation involving post-tension concrete pours.
A-American used MAPEI’s Planiseal™ VS alkali-resistant, epoxy moisture-reduction barrier for moisture mitigation throughout the complex. Planiseal VS expedites floor-covering installations by eliminating the traditional wait time required for new concrete slabs to reach moisture levels suitable for installations. After the concrete surface was properly profiled, the Planiseal VS was poured to cover each level in the building.
After moisture mitigation, the floors were primed with one of three primers – Primer L™, Primer T™ or ECO Prim Grip™ – where appropriate. Then the installers selected two MAPEI self-leveling underlayments – Novoplan® 2 Plus and Ultraplan® 1 Plus – to use in appropriate areas in order to produce a smooth, level surface for installing tiles and stone. Both of these products are quick-setting, self-leveling underlayments and repair mixes for interior concrete and engineer-approved floors.
MAPEI’s Mapelastic™ cementitious membrane was used for waterproofing and protecting exterior horizontal and vertical concrete spaces, while Mapelastic AquaDefense with Reinforcing Fabric, an advanced liquid-rubber, extremely quick-drying waterproofing and crack-isolation membrane, was used on interior surfaces before the tile and stone installations. Mapelastic AquaDefense dries after about 30 to 50 minutes and is then ready to receive any MAPEI polymer or epoxy mortar.
Range of mortars and grouts meet varying project demands
Installation of exterior and interior tile and stone also used a variety of MAPEI’s mortars and grouts. For the ultimate bond, Lava Stone Veneer pavers and curbs surrounding the building were installed with MAPEI’s two-part Kerabond/Keralastic™ system – a premium dry-set mortar that is combined with a flexible acrylic latex additive.
Where there was a need for speed, the A-American crews used the Granirapid® fast-curing system. Outdoor walls and benches that used Lava Stone Veneer and Cremino Stone Veneer in all sizes from mosaics to large-format tile were also installed with these two systems. All of these installations were grouted with MAPEI’s powerful Ultracolor® Plus FA – an ultra-premium, fine aggregate, fast-setting, polymer-modified, color-consistent, non-shrinking, efflorescence-free grout that can fill joint widths from 1/16” to 3/4”.
In the residences and townhouses, tile and stone played a dramatic role as field tile and accents on floors and walls. Types and brands included Caesarstone for countertops; Atlas Concorde floor tile in Seastone Greige and floor, wall and door accent tiles in Black for residences and public areas; Marmi porcelain wall tile in “Thassos”; Natural Stone Design’s porcelain floor and wall tile in Dark, Basaltina, plus mosaic tiles of the same material for residences and public spaces; Daltile’s quarry tile in Arid Gray for laundry rooms in residences; “Luce Glass” glass wall tile from North Shore for public restrooms; Ann Sacks’ 2” x 8” “INCA” brushed aluminum tiles for kitchen backsplashes; stone tiles in travertine, basalt, tundra stone and granite; “Nublado Light” and “Walnut Brown” wall base tiles from Stone Source; and many additional tile and stone selections that were optional for residents at time of purchase.
All interior tile and stone was installed with MAPEI’s thixotropic mortar, Ultraflex™ LFT™. This mortar has a high content of unique dry polymer, resulting in excellent adhesion to the substrate and tile and is formulated with Easy Glide Technology™ for ease of application. Both wall and floor tiles were grouted with Keracolor® S (sanded) and Keracolor U (unsanded) grouts from MAPEI’s grout color collections. The quarry tiles in laundry rooms and in the kitchen and prep rooms on the Amenities level were grouted with Kerapoxy CQ. This grout uses a proprietary aggregate to achieve its durable color, making it excellent for countertops, high-traffic areas, and areas needing stain and chemical resistance. Easy to maintain, Kerapoxy CQ will clean to the original color and contains BioBlock® technology to help protect against mold and mildew.
The A-American installers performed exceptionally well with the many different types of installations in many different parts of the project, but they truly excelled on the installation of the tile on the inside and outside of the cantilevered leisure/lap pool extension on the Amenities level. Working on a crane that lifted them seven stories into the air, the crew set sheets of black glass mosaic tiles on the interior and exterior sides of the glass-bottomed portion of the pool that extends 13 feet out from the building. They used MAPEI’s Adesilex™ P10 bright white, multipurpose thin-set mortar formulated with non-sag properties to set the tiles. The Adesilex P10 was mixed with Keraply™ for increased performance in a submerged installation. After removing the protective cover sheets, the tiles were grouted with Ultracolor Plus FA.
A total of 40 different products supplied by MAPEI – from substrate preparation to installation of all types of finished flooring – allowed the owners, architects, general contractors and installers, the peace of mind of sourcing all their needs from a single manufacturer to create a true island beauty.
