Concrete floors can sink from many reasons. Most reasons are poor compaction of the soil before construction; leakage of draining system causing the soil to soften and weaken; and excessive loads of machinery, merchandise, or transport trucks. 

When concrete floors sink, the problems that usually follow that affect businesses are ponding on roads that inconvenience traffic, tilting of machines or storage tanks, cracking of concrete; all of which can be hazardous for the staff and the operation.

Lifting sunken concrete floors by PU Foam (Polyurethane) injection

Tesla Engineering provides services for lifting-relevelling sunken concrete floors by injecting Polyurethane or PU Foam into voids. The foam will expand, compact the soil, and lift the sunken floor. High accuracy levelling lasers ensures that relevelling of the floor is precise while experienced engineers oversee every step of the operation.

Procedures for lifting sunken floors

Obtaining reference points with levelling lasers

Getting accurate level references or the elevation difference is a very important process to obtain data for topographic mapping as well as engineering construction. Tesla Engineering undertakes this operation as the first step in lifting-relevelling sunken floors. The procedure is carried out using high accuracy levelling lasers in order to identify the elevation and tilting direction of the area.
