tive 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™ underlay- ment 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 sur- face and improve the bond of the calcium aluminate-based under- layment. After just an hour of dry time for the primer, the instal- lation team poured TechLevel™ 150 Self-Leveling Underlayment up to 1-1/2” deep. Premium qual- ity TechLevel 150 achieves great- er than 4,300 psi compressive strength to resist point load, which is important given the weight of hospital equipment. “TechLevel 150 is my go-to lev- eler if I have a choice,” said Josh Reed, concrete division manager at the Rouse Company. “We definite- ly 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 rigor- ous product standards, unparal- leled technical support and qual- ity backed by an extended war- ranty. The high-use, high-traffic tile assemblies at Jacobs Medical Center qualified for a 15-year installation system warranty. Two lightweight Emerald Systems™ for- mulas included in the installation, ProLite and CEG-Lite, can also earn carbon offset credits for any project where they are installed. A project of this scope and scale CUSTOM tile installation sets standard of care at San Diego hospital Kitchen quarry tile was set with VersaBond® Flex Professional Thin-Set Mortar, which is formulated for high bond strength and extended adjustment time.
