What Wykamol Group does

Wykamol Group Ltd is a UK-based manufacturer of building preservation and renovation products, founded in 1934 and headquartered in Burnley. The company manufactures and distributes a comprehensive range of specialty chemical products organized around three core sectors: damp and timber treatment, structural waterproofing, and structural repairs. The portfolio includes BBA-approved cavity drain membranes (CM3, CM8, CM20 variants with mesh and geotextile options), silane-based damp-proofing creams, cementitious tanking systems, timber treatment concentrates, gas-proofing membranes (the Quadproof range with EVOH co-polymer barriers), anti-condensation systems, and Thor Helical structural repair products. Wykamol operates the UK's only Cavity Drain Membrane extrusion plant following a £2.5 million investment in 2018, giving it domestic manufacturing capability competitors lack.

The company serves property renovation and repair specialists, waterproofing contractors, architects, surveyors, housing associations, and homeowners, primarily through UK and Ireland building merchants, a Registered Installer network, and a direct technical sales team of CSSW-certified Area Technical Managers covering all UK regions. Pricing is quote-based through the technical sales team rather than publicly listed. In 2024, Wykamol was acquired by Mapei Group through its UK subsidiary Mapei UK Ltd, integrating the Wykamol brand into a global chemical building products manufacturer present in 57 countries. Post-acquisition, products are distributed across the UK, Ireland, continental Europe, the Middle East, Africa, and Australia, leveraging Mapei's international footprint. The combined Mapei UK operation, which includes Wykamol, recorded sales exceeding £110 million in 2023 with consistent year-on-year growth and a 370+ workforce.

• Delta Membrane Systems: UK manufacturer and distributor of Type C cavity drain membranes, sump pumps, and BS8102-compliant waterproofing systems. Competes head-to-head with Wykamol's CM3/CM8/CM20 range and Quadproof gas membranes in basement and below-ground waterproofing projects.
• Sovereign Chemicals (Fosroc): UK-focused manufacturer of damp-proofing creams, waterproofing slurries, and timber treatment chemicals — direct overlap with Wykamol's Ultracure DPC and Microtech timber ranges. Now part of Fosroc, expanding competitive pressure from a global specialty-chemicals player.
• Safeguard Europe: UK specialist in damp-proofing, timber preservation, and basement waterproofing products with comparable BBA-certified offerings. Competes directly with Wykamol in the contractor and merchant channels for rising-damp and structural waterproofing.
• Triton Chemicals: UK manufacturer of damp-proofing products, waterproofing membranes, and timber treatments. Overlaps with Wykamol's DPC creams, cavity drain membranes, and timber-treatment chemicals, and shares the same merchant and contractor distribution model.
