Slab Stabilization

SUMMARY

Atelier Bretagne operates 24 hours a day, 7 days a week, having to follow the rhythm of the orders made by clients. Over time, the subfloor had become progressively unsuitable to support the loads to which it was subjected daily. The continous passage of forklift on the floor slabs eventually caused damage. URETEK successfully stabilized these floor slabs. 

OBJECTIVES

The solution that included a stop in production was quite impossible, due to high costs. URETEK presented an ideal proposal, programming and planning carefully execution time for each phase of the intervention, so as to minimize interference with production activities of the company.

TECHNOLOGY APPLIED

Though studies made, URETEK verified that in the area around the expansion joints the pressure made by the loads was extremely high. Taking this observation into account, the drilling of the pavement was realized, in general, following a pattern with a hole in each m² of floor but increasing the density of the holes around the joints of expansion. The intervention required the execution of a series of holes of 12 mm in diameter in the floor and the laying of cannulae metal through which the UREETK geopolymer was injected in the substrate of the pavement. During the injections, laser levels were positioned to ensure unwanted lifts did not occur.

OUTCOME

Compacting of the subfloor of 7.000 m² of flooring without unwanted floor lifting and without substantial interference of production routine. Applying URETEK Geoploymer technology, it was possible to fill the voids by injecting the URETEK swelling geopolymer, designed specifically for this type of processing. By expanding, the geopolymer reinforced the subfloor in the area surrounding the injection point and reset the contact between the subfloor and floor. The success of the intervention was tested using sensitive indicators to the hundredth of a millimeter. The stabilization of 7,000 m² of floor required 35 working days and the use of about 20 tonnes of URETEK geopolymer.
