Cementaid

What Cementaid does

Cementaid (UK) Limited is a privately held British specialty chemicals manufacturer founded in 1954 and headquartered in Crawley, West Sussex. The company produces the proprietary Everdure Caltite System — an advanced concrete admixture and surface treatment that delivers integral waterproofing and corrosion protection to reinforced concrete, eliminating the need for external membranes and protecting steel reinforcement against salt water ingress. Over 70 years the formulation has been used in more than 30,000 projects covering over 10 million cubic metres of concrete, including high-profile UK infrastructure such as the British Museum Great Court, Wimbledon No. 1 Court, the Queen Elizabeth University Hospital, and GSK's headquarters.

The company operates a specification-driven, sales-led go-to-market model. Architectural and structural engineering practices specify Everdure Caltite into project drawings (supported by downloadable NBS Specifications and BIM objects on the website), and Cementaid's regional technical sales representatives then engage concrete producers and contractors to supply the admixture. Revenue is generated through one-time product sales on a project-by-project basis, with technical consultation and CPD presentations forming the primary demand-generation engine. The company holds a BBA Certificate, ISO 14001:2015, NBS Specification, EFCA Environmental Declaration, Singapore Green Building Certification, and Polish Institute of Hygiene certification, providing regulatory and procurement validation.

Cementaid serves construction companies, contractors, concrete producers, architects, and structural engineers across the UK and Ireland, with additional project footprints in the Channel Islands, Isle of Man, Gibraltar, Dubai (UAE), and Hong Kong. Customer use cases span basements, retaining walls, tunnels, swimming pools, marine structures, and rooftops — particularly where water ingress or chloride-induced reinforcement corrosion is a critical design concern. Headcount sits at 251–500 employees and ownership remains independent, with no disclosed parent, PE, or VC backing.

Broad incumbents

• Fosroc International: Fosroc manufactures a comprehensive range of concrete admixtures, grouts, and waterproofing solutions including integral waterproofing systems. It is a broad construction-chemistry incumbent with direct overlap to Cementaid's product lines in concrete protection.
• Tremco (Tremco CPG): Tremco Construction Products Group manufactures waterproofing, sealing and concrete protection systems for buildings and infrastructure. Its portfolio of membranes, coatings and specialty concrete products overlaps with Cementaid's waterproofing concrete offering as a broad incumbent.
• GCP Applied Technologies (Saint-Gobain): GCP (now part of Saint-Gobain) produces admixtures and waterproofing products including the Preprufe and Bituthane membrane lines. It is a broad incumbent that overlaps Cementaid both via concrete admixtures and below-grade waterproofing systems.
• Euclid Chemical: Euclid Chemical is a diversified manufacturer of concrete admixtures, construction products, and repair materials. It is a broad incumbent with overlapping waterproofing, repair and specialty concrete chemical offerings to Cementaid's Caltite System.
• Sika AG: Sika is a global construction chemicals heavyweight with a full admixtures and waterproofing portfolio including Sika® WT and other integral waterproofing systems. It competes with Cementaid primarily through scale, distribution breadth and as an incumbent specified alternative.
• Mapei: Mapei is a large global manufacturer of construction chemicals, including concrete admixtures, mortars, and waterproofing products. It is a broad incumbent competing in the same waterproofing concrete category but across a much wider product portfolio.
• BASF Master Builders Solutions: Master Builders Solutions (formerly BASF Construction Chemicals) supplies a comprehensive range of concrete admixtures and waterproofing systems. As one of the largest construction chemicals incumbents globally, it competes with Cementaid in the admixture and concrete protection category.

Direct peers

• Penetron International: Penetron manufactures crystalline concrete waterproofing admixtures and surface treatments used in basements, tanks, tunnels and marine structures. It is the most directly comparable specialist competitor to Cementaid's Everdure Caltite System in the integral waterproofing admixture category.
• Kryton International: Kryton produces Krystol crystalline waterproofing admixtures and surface-applied systems for concrete. It sells into the same use cases (basements, water tanks, marine structures) via similar specifier-driven channels, making it a direct niche competitor to Cementaid.
• Xypex Chemical Corporation: Xypex specializes in crystalline concrete waterproofing admixtures and surface treatments that protect concrete from water ingress and chemical attack. Like Cementaid, it targets the integral waterproofing niche for below-grade and water-retaining structures globally.
