After Spray-Lock application, tests showed that SCP 327 penetrated over 7.5 inches into the 9-inch thick wall, reducing potential for moisture issues, efflorescence, and shrinkage cracking. Thirty days later, there was no shrinkage cracking and no evidence of moisture or water intrusion through the wall. Continue reading

May 19, 2014 /prREACH/ -- Much of Tacoma, Washington is built on a hill overlooking beautiful Puget Sound. While the view is spectacular, Tacoma averages more than 37 inches of rain a year, creating a surface and subsurface water challenge for the business district below.
During construction planning, Mortensen and University of Washington-Tacoma Facilities teams addressed the challenge by installing pumps that move up to 4,000 gallons of water from the building footprint daily.
A 6800 square foot shotcrete wall system was also constructed to protect the new structure from the water run-off. The construction team included Spray-Lock Concrete Protection® (SCP) Technology as an integral part of their solution to prevent moisture intrusion into the building from the hill.
After Spray-Lock application, tests showed that SCP 327 penetrated over 7.5 inches into the 9-inch thick wall, reducing potential for moisture issues, efflorescence, and shrinkage cracking. Thirty days later, there was no shrinkage cracking and no evidence of moisture or water intrusion through the wall.
Because of these proven sustainability benefits of Spray-Lock’s Concrete Protection® Technology, SCP will be used in additional walls and the Student Center slab as construction continues. The Student Center is expected to open in January 2015.
About Spray-Lock Concrete Protection®, LLC (SCP) Established in 1982, Spray-Lock Concrete Protection® (SCP) manufactures spray-applied concrete treatments that penetrate into concrete capillaries and pores to waterproof and protect the entire capillary and pore structure. SCP technology ensures that concrete capillaries are blocked – permanently – thus turning the concrete surface into a suitable substrate for application of coatings and coverings. Testing has shown that SCP treatment performs concrete curing equal to or better than 28-day water ponding. This technology is a strengthening and surface hardening solution that also increases sustainability for concrete floors and structures. With over 30 years of successful projects, SCP Technology provides time-proven solutions for indoor and outdoor concrete.
