The Capital London Skyline

Capital Projects



Wandsworth Prison Gate House, London


The existing asphalt roof was in a very poor condition and the option of stripping the roof could not be considered, so capital proposed an overlay with a high performance liquid system 

Having carried out works previously on this site Capital were asked again to solve a water ingress problem over the roofs of the front gates house.

As with all these types of premises access & security was to be of a high priority.

The existing roof was asphalt and had been neglected and the existing slumps and fractures in the asphalt were very severe.

Stripping the roof was not an option and we recommended an overlay with a cold applied liquid waterproofing and Capital chose the Marley Polimar system.

Repairs were carried out by Capitals asphalt team prior to carrying out the overlay.

All our operatives including the scaffolding team had to be CRB checked before they were allowed to work on the site and all passed
5 roofs over the gate house were overlaid with Anti-slip walkways.

Wandsworth’s maintenance team were very impressed with the speed and quality and more importantly, no more leaks
