Damp-proof courses


Icopal is one of the largest manufacturers of waterproofing products in the world, and has long been a pioneer in the field of damp-proof courses (DPC).

Icopal’s DPC range provides benefits including high-tensile strength, tear strength and puncture resistance, to maintain waterproofing integrity during and after construction. Icopal’s DPCs are flexible at low temperatures for ease and speed of handling and detailing. They are also quick and easy to install. Superior mortar adhesion maintains structural integrity. Whether loads are high under multiple storeys, or light under copings, Icopal DPC provides exceptional performance under load.

The products accept complex geometry, allowing the most complicated details to be accommodated without compromising waterproofing.
The range includes Xtra-Load Engerseal, Xtra-Load Elite, Xtra-Load Nubit, and Xtra-Load Alumite. All products are either BBA approved, or comply with the requirements of BS 6398.
