Kemper System were specified for roof repairs for a occupied 1930s art deco municipal office building in Blackpool, Lancashire.

The building was experiencing standing water on a largely zero falls roof with only four drainage outlets, meaning water had started to leak into the occupied offices below.

Kemper System’s Stratex Warm Roof system using its Kemperol V210 was specified for the 1,200m2 roof area.

The Kemperol V210 is a polyester-based resin, applied wet-on-wet that forms a permanently elastic, seamless, yet highly durable waterproofing membrane.

The roof was extremely complex with detailing around air-conditioning units, raised steelwork and cable trays in close proximity.

All existing steel work on the roof was treated and encapsulated with plywood and waterproofed with Kemperol to ensure additional life span.

Contractors had to clean the roof prior to the application of Kemper System’s Kemperol V210. The lack of drainage meant any power washing created more ponding on the roof. Therefore, contractors used a vacuum wash and dry system that automatically extracted the waste water and pumped it directly down the drainage outlets.

After cleaning the substrate, contractors applied Kemper System’s Kempertec D Primer over the Kempertherm F insulation as part of the warm roof build-up. The insulation is rigid PIR board with multi-layer foil composite face on both sides, and has tongue and groove edges for interlocking construction.

Kempertec EP5 Primer was also applied prior to installation of Kemperol V210 to the roof deck and stairwell areas.

The cold-applied Kemperol V210 liquid resin saturates a non-woven reinforcement fleece that is tailored to the exact contours and details of the roof.

The waterproofing is installed in a single process and cures to provide a robust waterproof membrane that cannot delaminate and is UV stable.
