PU injection, also polyurethane grouting or injection, is a waterproofing technique which uses expanding injected polyurethane
PU Injection helps to prevent water flowing through and voids or cracks typically in concrete.
This is effective in solving water leakage issues, especially when applied on the underside of the seepage area or the lower floor ceiling where the leak occurs.
PU injection is a recommended method to be applied to actively-leaking cases involving concrete slabs.
