Summary

Newton Specialist Contractors ASF Waterproofing were called in to investigate why the Bridge Master’s Quarters at No.1 Tower Bridge was suffering from damp and proceeded to install multiple Newton products to resolve the issue.

The Project

At the world famous Tower Bridge, landscaping contractor Maylim was commissioned by the City of London Corporation to investigate why the Bridge Master's Quarters at No.1 Tower Bridge was suffering from damp.

After excavating, they discovered that the structure had no effective damp proofing protection. Newton Specialist Contractor ASF Waterproofing were commissioned to install new damp proofing measures to solve the issue.

The Solution

ASF Waterproofing approached the project in two phases, using multiple products to effectively damp proof both inside and outside the building. At the start of phase one, ASF correctly prepared and cleaned the internal wall surfaces before installing a new damp proof course by injecting Newton 804-DPC into the walls at regular intervals, then sealing the holes with Newton 313-WP. The walls were then smoothed with a new internal render, ready for Newton 103-S to be quickly and easily sprayed to provide a final barrier to water.

For phase two, the ASF team turned to the external walls of the structure, preparing and cleaning the surface before applying a new external render coat. The wall was then thoroughly waterproofed with four coats of the flexible, resilient Newton 109-LM. To ensure that the building was completely protected externally, the waterproofing began at 1-metre below ground level and extended all the way up to the existing windowsills.

The Result

Thanks to their meticulous attention to detail and high standard of installation, ASF Waterproofing were able to provide both the contractor and the client with a high quality and comprehensive damp proofing solution. As a result, the City of London Corporation can now hand over the building to the new lease holder, safe in the knowledge that it is well protected from damp.
