Waterways Lock Refurbishment

Water was tracking under the sill of this old neglected lock, washing away sediment beneath the oak beams. This was causing signs of failure in the structure.

To fix it, we cast a new sill and replaced the gate linings. We then discovered that water was penetrating the pillar core which meant we needed to find a solution that would not require costly stoppages and rebuilding.

The answer was an injection technique using specialist pumps and bore packers. This is a recent innovation, providing a permanent solution over a short period.

The polyurethane resin used is renowned for its high flexibility and good adhesion. Cracks repaired using this method, remain leak-proof even in the case of width modifications and dynamic stress. In this case, polyurethane resin provides a durable sealing effect through use of Spurr, making it ideal for cases of highly pressing water like this one.
