The Job
This chemical underpinning project is located outside of Pittsburgh, Pennsylvania at a manufacturing facility. Water began to seep through the floor of the shop, break room, and bathrooms inside a manufacturing facility. The investigation determined that a water line had broken, and weekend soils below the floor, causing the settlement. Voids were also present below the floor.
The Challenge
The client’s primary concern was addressing the stability of the area without affecting normal usage.
The Solution
CJGeo proposed chemical grouting to stabilize the weakened soils, along with structural polyurethane grouting to fill voids. Previous repairs to address floor settlement had been completed, so a hydro-insensitive undersealing polyurethane grout was used to ensure stability without lifting the slab.
Due to saturated soils, CJGrout 35NHV was the best material for filling voids immediately below the floor. 35NHV is a normal speed, hydro-insensitive geotechnical polyurethane, specifically formulated for void filling applications. It provides high bearing capacity, and minimizes the chance of undesirable lifting during installation.
