Water Proofing Contractors
150 / sq ft
Onyx Engineering delivers comprehensive waterproofing solutions for concrete, masonry, and hybrid substrates across new builds, retrofits, and remedial works. Our systems combine advanced membranes, coatings, and injection techniques with meticulous surface preparation to protect structures from water ingress, moisture, and durability challenges.
Key benefits
Robust barrier solutions: sheet membranes, liquid-applied coatings, and crystalline technologies
Multi-layer protection: surface prep, priming, barrier, and protection systems
Flexible performance: potable-water compatibility, salt exposure, and hydrostatic pressure resistance
Safety and compliance: method statements, risk assessments, and quality documentation
Typical applications-Below-grade waterproofing for basements, tunnels, and car parks
Shower, bathroom, and utility room waterproofing in new builds and renovations
Roofing and balcony membranes, terrace waterproofing, and deck coatings
Structural crack injection and moisture mitigation for heritage projects
2) Expanded ServiceOverview:
Our Water Proofing Service provides engineered protection against water ingress, moisture migration, and chemical attack. We tailor solutions to substrate, exposure class, and project delivery constraints, ensuring long-term durability and compliant installation.
What we do
Surface preparation: cleaning, profiling, moisture testing, and crack mitigation
System selection: bituminous, polymer-modified bitumen, elastomeric, cementitious, crystalline, and polyurethane options
Application methods: membrane installation, coating applications, injection grouting for cracks
Protection & detailing: edge detailing, expansion joints, penetrations, and drainage integration
Verification & testing: adhesion tests, holiday testing (conductivity checks), and as-built documentation
Maintenance & repair: coating refresh, patching, and localized injections
