Automotive Tunnel Water Leak Concrete Repair
This tunnel is used for getting from one building to another underground during rainy or snowy weather.
They had 3 different contractors come in to fix the situation and all 3 of those solutions had failed.
The USI Team went in and started prepping the floor and while peeling the base board off of the wall, discovered that the leak was even coming through the wall.
After scraping out 4 inches of wet concrete from within the wall, and almost 10 inches off of the floor, the USI Team used Resimac Resichem 574 Fastfill Plug to stop the leaks. This is a single component fast curing engineering grade, polymer modified, reactive cementitious putty for arresting water seepage and infiltration under pressure through cracks, joints and voids in concrete and masonry.
After the USI Team stopped the active leaks, we topped off the area with Resimac Resichem 572 Concrete Seal CWC. This is a single component, engineering grade, polymer modified, reactive cementitious coating with high adhesive properties. It is used in permanent immersion or negative pressure waterproofing. It resists hydrostatic pressure up to 145 PSI. The project has now been in service for over 2 years now and the customer has invited the USI Team back to do 3 more projects.
