Professional Associations

Formerly part of the BWPDA, the PCA is the premier trade body for the structural waterproofing, wood preservation, damp proofing, flood remediation and structural maintenance industries in the UK.

PCA members offer professional advice and help in their area of expertise – approved members include damp proofing companies, structural waterproofing, structural maintenance and timber preservation experts, specialising in rising damp, flood remediation, basement conversions, structural damage, dry rot and wet rot. For homeowner surveys - both pre and post purchase - PCA members can be trusted to provide peace of mind through a correct diagnosis, completed by skilled and experienced operatives. Damp proof training and other courses are available from the PCA, including timber treatment and condensation.

The Concrete Repair Association

The CRA was formed in 1989 to set high standards of workmanship and technical competence. Nowadays, the Association is committed to promoting and developing the practice of concrete repair and corrosion protection, as well as advancing education, technical training and health & safety matters in structural strengthening and crack bridging among other areas.   Members companies include specialist contractors, product manufacturers and product distributors established in the field of concrete repair, as well as associated organisations, such as testing laboratories.

  • Promotion of qualifications and training for members involved in specifying and applying waterproofing systems
  • Publications such as Waterproofing Existing Basements and the Basement Waterproofing Design and Site Guides
  • Promoting standards through the trade press and construction authorities
  • Helping customers to find the most appropriate member for their requirements
  • Thorough vetting of applicants to ensure provision of the necessary expertise in this specialist field.

SAFE contractor accreditation is a programme which recognises very high standards of health and safety practise amongst UK contractors. Under the SAFEcontractor system, businesses undergo a vetting process, which examines health and safety procedures and their track record for safe practice. Many major clients recognise the scheme and accept the SAFEcontractor certificate as confirmation of a company’s competency.
