Chemical stabilisation/ flood grouting

Chemical Stabilisation/flood grouting, utilises the chemical reaction between two liquid compounds to form a solid fill within a pipe defect.

This can be achieved either using full manhole to manhole flood and fill operations or localised using sealing packers either side of the defect provided that the packers allow for pumping and extraction of the individual chemicals. Chemical one is first pumped in and allowed to flow into the defect, through the pipe wall into the surrounding ground. This is the quickly extracted and the second chemical pumped in. As it meets and mixes with the Chemical one the reaction causes a solid material to be formed with the defect so sealing it. If required a robotic system can be used to smooth off any intruding ‘product’ and clean the pipe once the process is completed. The process also repairs laterals if the chemicals are allowed to flood into these connections.
