Dryseal gets Zero in BBA test

BBA 95/3114 Logo

BBA_Dryseal_November_2014Hambleside Danelaw submitted the Dryseal GRP mechanically fixed, component based waterproofing membrane to the British Board of Agrément for ‘zero-falls’ testing and accreditationn.

Dryseal was submerged in water at 60°C for 6 months, and then was subjected to a series of rigorous tests for water penetration, material bond strength, indentation and tensile characteristics.

Dryseal was submerged in water at 60°C for 6 months, and then was subjected to a series of rigorous tests for water penetration, material bond strength, indentation and tensile characteristics.

In September 2014, Dryseal passed with flying colours with “no water penetration”, and withstood a maximum tensile load requirement of over 22 kN/m, with negligible change from the original sample.

Now Agrément Certificate 95/3114 has been re-issued with full ‘zero-falls’ accreditation. Dryseal can now be used on roofs with falls less than 1:80, a common requirement for terrace areas and roof gardens.

The NHBC will only allow the use of fully independently accredited waterproofing systems in ‘zero-falls’ installations. Dryseal has now been proven to achieve the requirements.

Andy Fell, Hambleside Danelaw Dryseal Manager, said: “We’re delighted at this authoritative proof that the advanced characteristics of Dryseal can easily satisfy the ever increasing demands made on modern roof covering systems.”
