Waterproofing & Insulation Services
Application-led protection above and below ground—from roofs and basements to wet areas, water-retaining structures, landscaped decks, and repairs.
One scope. Considered in context.
Final system selection depends on the project specification, substrate, use, and site conditions.
Roof Waterproofing & Insulation
Coordinated waterproofing and insulation for new roofs, exposed surfaces, and roof refurbishment.
Roof protection is considered as a complete build-up: substrate, falls, waterproofing, thermal insulation, and protection. New installations and refurbishment require a system selected for the roof’s use and existing condition.
Typical application areas & suitable systems
New flat roofs & combo roof systems
Systems- Specified combo roof assemblies combining compatible insulation, waterproofing, and protective layers.
- Torch-applied bituminous membranes where the substrate, roof build-up, and hot-work controls permit.
Application notesCoordinate insulation thickness, vapour control, falls, outlets, upstands, and termination details as one roof assembly.
Exposed roofs & coating systems
Systems- Polyurethane liquid waterproofing systems with the specified reinforcement and UV-resistant finish where required.
- Silicone roof coatings on sound, prepared substrates where adhesion and system compatibility are confirmed.
Application notesConfirm substrate moisture limits, adhesion, drainage, coating thickness, and suitability for exposure and maintenance traffic.
Roof refurbishment
Systems- Compatible membrane overlays or liquid-applied systems after assessment of the existing roof.
- Selective removal and replacement where the existing build-up cannot be retained.
Application notesInvestigate trapped moisture, failed interfaces, and the existing insulation before deciding whether to retain or remove layers.
Important technical considerations
- Confirm the thermal design, roof loading, access requirements, and all interfaces against the project specification.
- A coating is not a substitute for correcting defective falls, unstable substrates, or failed roof details.

Request a QuotationSubstructure Waterproofing
Below-ground protection for foundations, basements, and retaining walls, coordinated with joints and groundwater conditions.
Below-ground waterproofing must respond to groundwater conditions, construction sequencing, and the concrete structure. Continuity across slabs, walls, and joints is central to the design.
Typical application areas & suitable systems
Raft foundations & base slabs
Systems- Specified bituminous sheet or self-adhesive membrane systems on prepared blinding where suitable.
- Crystalline waterproofing for suitable concrete applications where specified, as part of the coordinated waterproofing design.
Application notesMaintain continuity at pile heads, slab edges, and service penetrations; protect membranes before reinforcement and concreting.
Basements & retaining walls
Systems- Bituminous or self-adhesive membranes selected for the substrate and anticipated below-ground exposure.
- Compatible protection boards and drainage layers where required by the design.
Application notesAssess hydrostatic pressure, substrate preparation, wall-to-raft transitions, membrane terminations, and backfill protection.
Construction joints & penetrations
Systems- Centrally cast, external, or hydrophilic waterstops selected for the joint design.
- Compatible penetration seals and joint treatment systems coordinated with the surrounding waterproofing.
Application notesWaterstop position, restraint, concrete compaction, joint movement, and installation access must be resolved before casting.
Important technical considerations
- Crystalline treatments do not eliminate the need to detail movement joints, construction joints, and penetrations.
- System selection must consider water pressure, groundwater chemistry, access, and the required protection strategy.

Request a QuotationWet Area Waterproofing
Detailed protection for bathrooms, kitchens, laundries, balconies, and terraces, compatible with adjacent finishes.
Wet area systems are selected around the substrate, expected water exposure, movement, drainage, and finish. Junctions and penetrations receive the same attention as the main surface.
Typical application areas & suitable systems
Bathrooms & washrooms
Systems- Flexible cementitious waterproofing beneath compatible finishes.
- Selected polyurethane systems where specified and compatible with the substrate and tile build-up.
- Corner, junction, and pipe penetration reinforcement integrated with the selected system.
Application notesConfirm upstand heights, drain interfaces, curing periods, and finish compatibility before tiling or testing.
Kitchens & laundry areas
Systems- Flexible cementitious or compatible liquid-applied waterproofing selected for the exposure.
- Compatible collars, reinforcement, and seals at drains and service penetrations.
Application notesCoordinate falls, thresholds, service routes, and compatibility with floor finishes and adhesives.
Balconies & terraces
Systems- Polyurethane liquid membranes with suitable exposure or protective layers.
- Flexible cementitious systems or suitable sheet membranes where specified for the proposed build-up.
Application notesAccount for thermal movement, movement joints, drainage falls, door thresholds, outlets, and protective finishes.
Important technical considerations
- Confirm substrate condition, moisture limits, and compatibility between the membrane, adhesive, and final finish.
- Testing and covering-up should follow the specified system’s curing and inspection requirements.

Request a QuotationWater Tanks & Swimming Pools
Waterproofing and specialized lining for water-retaining structures, with careful joint and penetration detailing.
Water-retaining structures require waterproofing appropriate to the stored water, immersion conditions, structure, and finish. Lining selection is project-specific, particularly for drinking-water storage.
Typical application areas & suitable systems
Concrete water tanks
Systems- Cementitious waterproofing selected for the concrete substrate and intended water exposure.
- GRP lining for suitable applications, with the complete resin, reinforcement, and lining system specified for the service conditions.
Application notesFor potable water, require specific drinking-water contact certification or approval applicable to the complete proposed system; GRP is not inherently potable-water suitable.
Swimming pools & water-retaining structures
Systems- Flexible cementitious systems beneath compatible tile or other specified finishes.
- Specialized lining systems where suitable for immersion, water chemistry, and the intended finish.
Application notesCoordinate structural movement, filling and testing sequences, curing, tile adhesives, and exposure to treatment chemicals.
Joints, outlets & penetrations
Systems- Specified waterstops at construction or movement joints.
- Compatible flexible joint seals and proprietary penetration details integrated with the selected membrane or lining.
Application notesDetail changes of plane, pipe entries, fittings, and movement interfaces before the main lining is applied.
Important technical considerations
- Verify immersion suitability, stored-water chemistry, preparation, and curing requirements for the complete system.
- No potable-water suitability, certification, or project approval is implied without verification of the selected products and installation.
