Grouting & Road Void Grouting Techniques


Concrete road slabs have a tendency to sink or rock during the course of their serviceable lives, due to instability of the underlying sub-base material, usually brought about by water flow or pumping action beneath the slabs. The costly alternative of demolition and reconstruction can be avoided by introducing grout beneath the slabs, using vacuum to create an upward air flow, thus ensuring effective void filling with minimal wastage.

Misaligned slabs can be lifted back to correct levels using specialist chemical grouts.

This process has been modified to stabilise floor slabs, as typically found in factories and warehouses and can also be used to underpin private dwellings. The use of rapid setting injection materials enables slabs to be returned to service within hours of treatment, thus minimising disruption to normal operations.

Resitech can also undertake general cementitious grouting of voids, machine bases and redundant services. Deep voids can also be filled using probe injection techniques.
