A popular East London church has regained its post-war glory thanks to the solvent-free and odourless liquid waterproofing solution from Kemper System.

Kemper's manufacturer’s Stratex Warm Roof system and Kemperol 2K-PUR liquid waterproofing solution was specified to refurbish the Calvary Charismatic Baptist Church in Poplar. For many years, financial challenges meant the church had to carry out temporary repairs, which included a timber structure built over the entire roof area, and a felted covering on top of the original roof surface.

The initial single-ply specification was changed to Kemperol 2K-PUR by architects, A&RME, to provide a liquid waterproofing solution capable of addressing the complex design of the building with its concrete gutters and columns, as well as a number of round rooflights - meaning Kemper System’s seamless waterproofing solution was ideal for the level of detailing required.

The Stratex Warm Roof system, comprising Kempertherm insulation and Kemperol 2K-PUR cold applied liquid waterproofing membrane, was quick and easy to apply, minimising possession times on site and allowing the community to enjoy the church at its best once more. Roofing contractor, Capital Roofing Co Ltd of Blackheath in Greenwich, installed the roof system which involved removal of the timber structure and felt layers to reveal the 40 original circular skylights.

Chris Shulver at Capital Roofing Co Ltd, said: "Thanks to Kemperol’s quick and easy application, we could tackle the high level of detailing required on site with ease. It also decreased the time required for the temporary roof because of the single, wet-on-wet application process that doesn’t require the base coat to cure before subsequent site visits and further coatings are applied, unlike wet-on-dry systems.”
