Shrewsbury Flood Defence Wall Receives Gunite Group Injection Solution
We are very proud to share that our Infrastructure team has successfully completed an innovative and effective construction joint waterproofing project, on a Grade II listed heritage flood defence wall in Shrewsbury.
Once it was discovered that the construction joints were leaking, a solution was required to effectively seal the joints, without drilling into the Grade II listed heritage structure. Our answer was to use innovative 'Bee Sting Injection Packers'. The packers allow the polyurethane sealing resin to be passed through a small needle aperture, allowing the injection needle to be pushed through the newly installed joint sealant. This acts as a backstop for the closed-cell, highly elastic, polyurethane resin to bond and form a permanent seal at the back of the joint, without the need for any invasive drilling.
The final outcome was well received by all project stakeholders, providing safe and long-lasting results with minimal disruption caused by the process.
