Case Study Wellington Arch
One of Harrison Waterproofing’s projects was to install a waterproofing system in the vaults of Wellington Arch, London. A cementitious waterproofing system was installed.
A cementitious waterproofing system maintains a dry environment, in an underground area, by creating a physical internal barrier to damp and water. For this type of system we are authorised and recommended by industry product leaders, Sika Ltd.
The first step towards a successful Sika system is adhesion and it’s essential the substrate is suitably prepared, either by Scabbler or Bush Hammer, prior to work starting. Thereafter, if there is any likelihood of movement, we also recommend the use of combiflex movement joints around wall / floor joints. False economies here can lead to expensive problems further down the line.
