Prelasti EPDM waterproofing membrane is an ideal solution for tanking purposes. Sheets are prefabricated to suit client requirement, and vulcanised to form a single sheet up to 1200m2 in size. Prelasti EPDM can be loose laid with ballast, fully bonded, or attached using mechanical fixings.

Structural waterproofing of buildings is vitally important to prevent ingress of water and damp- a bigger problem than ever before with climate change now bringing us 100 year flood events on a semi-regular basis. Commercial and domestic properties in flood prone areas can be better protected, to a large extent, by appropriate tanking and defences being applied.

AAC Waterproofing have years and years of experience with commercial and domestic tanking, foundation and structural waterproofing using Prelasti EPDM membranes as well as specialist liquid applied systems to provide the highest possible levels of protection. Our teams operate throughout the UK - for more information, please contact us.
