LRWA

The LRWA consists of the leading manufacturers of liquid applied waterproofing, approved contractors

he LRWA was originally formed as the BRCMA (Bituminous Roof Coating Manufacturers Association), in the 1970’s in order to promote good practice in the industry. In the early 90’s it became apparent that growth in non-bituminous products was active and the association reinvented itself as ELRA (European Liquid Roofing Association) incorporating all liquid roofing systems. Additionally the organisat

ion was being recognised as an industry voice and thus became involved with the drafting of European standards. In 2005 a second reinvention recognising the wider markets that the liquid waterproofing was being used in, resulted in the formation of ELWA (European Liquid Waterproofing Assocation)

In 2010 the association recognised the need for an industry voice for the fastest growing sector of the roofing market in the UK and refocused once again to include Roofing. The association re-launched to become the Liquid Roofing and Waterproofing Association.

📢 Another LRWA Technical Guidance Update

Following the recent updates to Guidance Notes 14 and 16, Guidance Note 18 - Electronic Integrity Testing for Liquid Applied Membranes has also been updated.

Electronic Integrity Testing (EIT) plays a vital role in verifying the integrity of waterproofing membranes before finishes are installed - helping to identify breaches early, reduce costly remedial work and provide greater confidence in the completed installation.

If you’re involved in the design, specification, testing or installation of liquid applied waterproofing systems, make sure you’re working from the latest guidance.
