Established since 1970

AAC Waterproofing has been established since the 1970s and was one of the first UK companies to adopt and operate extensively with single-ply EPDM membranes.


We were also one of the early developers of off-site build techniques and we boast a purpose-built facility providing accurate, efficient prefabrication of high quality waterproofing solutions. Ultimately, this reduces the amount of time required for on-site installation.

We are the sole UK distributors of Prelasti made-to-measure EPDM. This is a very versatile system that has been specified in a wide range of projects from public sector, commercial & private buildings,

cutting-edge architectural structures, cladding, tanking, lakes and ponds, to waterproofing for extreme environment situations.

We are also approved installers of Sika Sarnafil and e-Lastic liquid PU membrane. You can see some of our projects here.

We have ISO 9001 and ISO 14001 accreditation and are CHAS registered. You can download copies of these certificates here.
