    Waterproofing Job in Tallahassee, FL

    The building had previously been waterproofed. The sealant had deteriorated and failed -- This was allowing water to infiltrate through the cinder block into the conditioned area. Our crew dug trenches along three of the four exterior walls, cleaned the debris and dirt off the walls, applied a waterproofing sealant, and lastly, filled the trenches back in.

    The Indoor Environmental Management team cleaned and disinfected the entire wood floor system in the crawlspace. The original crawlspace access door and sump pump were also replaced. A proper vapor barrier was installed with complete coverage of the crawlspace soil floor, with no exposed gaps, up the foundation walls, and wrapped around all support piers. A Sanidry CX was also installed with discharge lines to the exterior of the residence.

    The IEM crew built a retaining wall along the edge of the downhill slope on the side of the house. Behind the wall, they installed french drains and used membrane to keep water from seeping through the wall.

    This homeowner in Tallahassee was tired of being unable to use their old crawl space with ripping insulation and nasty looking walls. They called our office at Indoor Environmental Management and we sent out a crew to transform their crawl space right away. Our crew installed a patented CleanSpace Vapor Barrier system and now the homeowner is pleased with their healthy and attractive storage solution!
