HERTALAN® have been issued with a new BBA certificate (nr. 91/2728) which covers both our hertalan easy cover and hertalan easy weld roof waterproofing systems for ballasted, adhered and mechanically fastened applications.


The British Board of Agrément (BBA) is the UK’s major authority offering approval and certification services to manufacturers and installers supplying the construction industry. BBA Certification is recognised by building control, government departments, architects, local authorities, specifiers and industry insurers like the NHBC.

For a product to be considered for BBA certification it must reach the strict guidelines set up by the authority and must comply with the following :

/ factors relating to compliance with Building Regulations where applicable
/ factors relating to additional non-regulatory information where applicable
/ independently verified technical specification
/ assessment criteria and technical investigations
/ design considerations
/ installation guidance
/ regular surveillance of production
/ formal three-yearly review.



The following key factors have been assessed by the BBA when awarding HERTALAN® EPDM with certification:

Weathertightness — the systems and their joints, when completely sealed and consolidated, will resist the passage of moisture to the interior of the building (see section 6).
Properties in relation to fire — results of tests indicate that the systems will enable a roof to be unrestricted under the Building Regulations
(see section 7).
Resistance to wind uplift — when correctly specified, the systems will resist the effects of any wind suction likely to occur in practice (see section 8). Resistance to foot traffic — the systems will accept, without damage, the limited foot traffic and loads associated with installation and maintenance of     the systems (see section 9).
Durability — under normal service conditions, the systems will provide a durable waterproof covering with a service life of at least 25 years
(see section 11).
