High performance asbestos roof coating secures BBA accreditation

A team of building surveyors and polymer chemists, who introduced a new coating system for asbestos roofs, have seen their efforts rewarded with prestigious certification from the British Board of Agrément (BBA).

Solihull-based Liquasil, which manufactures a range of innovative polymer based, liquid roofing systems, received the accreditation, widely accepted as the only true fitness for purpose test in the UK’s construction industry, for its unique Asbestoseal system.

The UK’s only BBA approved system of its kind for treating the problems associated with aged asbestos roofs, it includes a corrosion treatment for metal fixings, a sealer for small holes and cracks, plus the full roof coating which is available in solvent and solvent-free  versions.

It carries a 20 year manufacturer’s product warranty when installed by an approved installer and has a life-expectancy in excess of 100 years. Uniquely, it is available in any RAL colour.

More than 50,000 sq metres of Asbestoseal have already been installed throughout the UK and part of the BBA certification process involved site inspection as well as extensive laboratory testing over a two year period.

Commenting on news of the certification, Robert Street MRICS, Director of Liquasil, said: “We have always been confident that Asbestoseal is the best performing asbestos roof   coating system on the UK market, but BBA accreditation is absolute proof of this.

“As Chartered Building Surveyors, we have traditionally preferred to specify new roofs wherever possible, but of course this is the most expensive option. We designed the Asbestoseal system to provide a more affordable alternative that gives surveyors and   other professionals absolute confidence when undertaking asbestos roof refurbishment.”

Liquasil’s product range, which also includes systems for gutters and metal roofs, is available via a nationwide network of approved installers, each of whom has undergone comprehensive training in product application, health & safety and roof cleaning methods.

For companies interested in becoming approved Liquasil installers, the company offers regular installer training and CPD sessions for surveyors and other professionals. More information can be found at
