The Registered Waterproofing Contractors Scheme has been introduced for use in conjunction with the Sika®-1 Pre-bagged waterproofing system, SikaProof® and Sikaplan®. The need to reduce the risk to both specifier and client has given rise to this scheme, which is designed to facilitate the selection of assessed contractors. It allows total quality control – from product to service to installation, granting clients complete peace of mind with a wholly professional service nationwide. The main benefit of the Registered Contractor Scheme is to help minimise risk. Not only can clients be sure of excellent standards of materials and workmanship, both can be guaranteed for a period of up to 15 years.

The criteria includes:

  • Stable trading history
  • Satisfactory project references
  • Proven commitment to safety, health and environment
  • Compliance with all relevant British Standards
  • Appropriate insurance cover
  • VAT Registered
