Professional Remedial Services Ltd

What Professional Remedial Services Ltd does

Professional Remedial Services Ltd (PRS) is a specialist contracting firm founded in 1981 and headquartered in Oldham, Greater Manchester, focused on the design, supply, and installation of structural waterproofing and ground gas resistant membrane systems. The company serves building contractors, house builders, housing associations, local authorities, and commercial clients across the North of England (Manchester, Lancashire, Yorkshire, Cumbria, Cheshire). Its service portfolio spans four core lines: structural waterproofing installation (cavity drain membranes, waterproofing coatings, BS8102:2022-compliant designs), gas membrane protection against radon, carbon dioxide, methane, VOCs and hydrocarbons, attenuation tank installation for Sustainable Drainage Systems (SuDS), and damp proofing/damp remediation.

The company's technical capability is built on a credentialed workforce rather than proprietary technology: full-time surveyors hold CSSW (Certificated Surveyor in Structural Waterproofing) and CSRT qualifications, while in-house installation technicians hold NVQ Level 2 Diplomas in Substructure Work Occupations and CSCS cards. PRS is an approved installer for four major membrane manufacturers — Delta Membranes (30+ year relationship), Visqueen (10+ years), Newton Waterproofing (10+ years), and Fosroc — and holds memberships in the Property Care Association (PCA), Structural Waterproofing Group (SWG), CHAS, and Trust Mark. The company issues company guarantees and QANW insurance-backed guarantees on qualifying works.

Revenue is generated entirely through project-based, quote-driven contracts secured via tender response, manufacturer referrals, and direct enquiry. Pricing is not publicly disclosed. Distribution is exclusively direct (field/enterprise sales) with no retail or e-commerce channels. Marketing is centered on the company's content website (gas-membranes.co.uk), CPD-accredited training seminars co-developed with Ground-Gas Solutions and Visqueen, and an extensive published case study portfolio. The company is privately held with no disclosed investors, funding rounds, or parent entities.
