It is a process of grouting in which the polyurethane material is injected and expands to fill up voids and seal cracks for slab lifting and leveling. It is commonly used for waterproofing, to create barrier on flow water, structure re-leveling, seal joints and structural cracks.
Polyurethane grouting is injected under low pressure to structural members on repair mostly on slabs, walls and foundations. The grout material usually reacts when encounter water flow it will expand and fill up voids on slabs and other structural member on repair. Grout techniques consider different factors such as viscosity, time reaction, water reaction, movement of grout on voids.
Polyurethane grouting advantages are fast, cost efficient, and very effective for settlement and instability.
Polyurethane Grouting is the highly recommended method for slabs, high carrying slabs, on an organize area wherein cleanliness is observed, for surfaces with sensitive value or quality and on load sensitive areas.
