The British Structural Waterproofing Association (BSWA)

Extreme care should be taken in appointing the right professionals to specify and undertake the work, as any problems arising can have serious consequences. Ninety nine percent accuracy in most skilled trades would be considered an excellent standard whereas in structural waterproofing it could constitute total failure! In this vital area of construction, technical products are all too often specified by people without the requisite knowledge and experience, and applied by untrained labourers with little knowledge of the exact requirements, resulting in failure.

Established in 1992, the British Structural Waterproofing Association is a trade association dedicated to raising levels of professionalism in structural waterproofing. Its members, who have passed rigorous checks to be approved for membership, include international product manufacturers, independent consultants and trained, assessed specialist contractors. To avoid dealing with inexperienced and untrained structural waterproofers, a BSWA member should be sought.

Delta Logo

DELTA Registered Installer

DELTA® Systems are installed by a Nationwide network of specialist contractors who are holders of “Registered Installers” Certificates.

Although DELTA® Systems are by comparison, easy to install, it must be recognized that the correct diagnosis of the problem is essential so that DELTA® Systems can be designed and tailored to the needs of the building, to give the best possible performance. It is therefore recommended that only competent specialist contractors, who understand dampness, and the associated problems, be employed to survey the site, install the system and thereby ensure the best possible performance of the system.

White Rock surveyors hold the industries regognised qualification CSSW (Certificated Survey In Structural Waterproofing) and all our basement waterproofing systems are installed to BS8102 2009

Product Guarantee

Delta membrane systems can come with a thirty year product guarantee as long as it is installed by one of delta,s registered installers. The guarantee covers the membrane and ancillary components. Based on experience, accelerated ageing tests and a quality manufacturing system to ISO 9001, the DELTA® range can also be guaranteed with confidence.

White Rock can also provide installation guarantees, which can be further supported by GPI insurance cover if required. The period of guarantee offered is normally up to 10 years and there is a small premium required for this facility.

Wall Tie Federation Logo


The Wall Tie Installers Federation is the representative trade organisation for registered installers of remedial and replacement wall ties and related services in the UK.

Most registered installers also offer the ancillary services of lateral restraints and bed-joint reinforcement all carried out in conformity with the recommendations of the Building Research Establishment. The WTIF have a guarantee insurance bonding scheme, covering cavity wall tie work, which is only available to members.

The Federation is nationally recognised as the accepted reference point for professional bodies and private individuals seeking information or guidance on these subjects.

The Wall Tie Installers' Federation can help in two ways: with the selection of a Registered Installer to inspect and, if required, to do this work and with an insured Warranty on the completed work so that if it is necessary to sell the house in the future the Warranty can be offered to the purchaser to whom the Federation will upon request transfer the unexpired term of the Warranty.

Registered Installers are experienced in the diagnosis and remedial treatment of wall ties and any ancillary work required.

If you are considering a house-purchase, a wall tie survey by a Registered Installer should certainly be included in your preliminary investigations before making an offer. In some areas it will be required as a precondition of a mortgage being offered on a property.
