Polyurethane Injection Grouting
PU grouting is a specialised technique that involves the injection of expanding polyurethane to stop any water flowing down or through cracks or to fill voids under slabs, concrete joints or behind concrete walls and joints.
Polyurethane injection grouting can be applied where water dripping occured. We can arrest leakage of below ground level structure, seepages from surrounding soil, or heavy dripping of concrete roof or terrace from negetive side. However most common applications are for below ground level concrete structures, where we want to stop leakage immediately.
