015 systems
Sheet membranes
Factory-made sheets of set thickness, bonded or welded at the seams on site.
Bituminous membranes (SBS & APP)
Modified-bitumen rolls torch-bonded with overlapping laps, for protected roofs, basements and foundations.View the system
PVC membranes
A synthetic sheet with hot-air welded seams, suited to large and exposed roofs.View the system
EPDM membranes
A flexible synthetic rubber in large sheets that copes with UV and movement, for exposed and garden roofs.View the system
Geomembrane & HDPE liners
Polymer sheets thermally welded on site to line lakes, large reservoirs and flood channels.View the system- TPO
TPO membranes
A single-ply thermoplastic polyolefin sheet with hot-air welded seams, for exposed roofs.View the system
024 systems
Liquid-applied & linings
Materials applied as liquids that cure into one continuous, seamless layer.
Liquid polyurethane waterproofing
A liquid membrane that cures into a continuous, seamless rubbery layer, strong at details and penetrations.View the system
Polyurea waterproofing (hot & cold)
A fast-curing, tough polyurea layer, hot-sprayed with dedicated equipment or cold-applied.View the system
Clear polyurethane coating
A clear polyurethane film that keeps surface water out of tiles and stone without changing how they look.View the system
Epoxy tank linings
A continuous, smooth epoxy lining for water tanks, using products certified for drinking-water contact.View the system
032 systems
Cementitious & crystalline
Cement-based systems that bond to the concrete or work inside its pores.
041 system
Injection
Resins injected into cracks to stop water or restore the bond.
051 system
Joint systems
Treatments that let the structure move while keeping the joint watertight.
063 systems
Thermal insulation
Layers that cut heat flow through roofs and walls.
Spray polyurethane foam insulation
A closed-cell rigid foam sprayed in place to form continuous, joint-free thermal insulation.View the system- XPS · EPS
XPS & EPS insulation boards
Polystyrene boards: XPS for inverted roofs, load and moisture; EPS for protected walls and ceilings.View the system 
Inverted roof system
A roof build-up with the insulation above the waterproofing membrane, shielding it from heat and impact.View the system
073 systems
Concrete repair & protection
Restoring damaged concrete and protecting it and its reinforcement.
Concrete repair with repair mortars
Breaking out damaged concrete, treating the reinforcement and rebuilding the section with a suitable repair mortar.View the system
Anti-carbonation coatings
A coating that restricts carbon dioxide entering concrete, slowing carbonation and rebar corrosion.View the system
Protective coatings (corrosion & chemicals)
Multi-coat systems that isolate steel and concrete from moisture and chemicals.View the system
083 systems
Flooring
Resin and cement-based floor layers chosen for use and traffic.
Epoxy flooring
Roller-applied or self-levelling epoxy floors: seamless and easy to clean, for factories, warehouses and facilities.View the system
Car-park coatings & line marking
Car-park floor coatings built for tyres and abrasion, with bay lines, numbers and arrows.View the systemMicrocement
Thin, hand-trowelled cementitious coats for floors and walls, with a seamless look.View the system
092 systems
Falls, drainage & protection
The layers that lead water away and protect the waterproofing.
QQuestions
Questions clients ask
What are the types of waterproofing?
Sheet membranes (SBS and APP bituminous, PVC, TPO, EPDM, HDPE liners), liquid-applied membranes that cure in place (polyurethane, polyurea, clear coatings, epoxy linings), cementitious and crystalline systems, crack injection and joint systems. The type is chosen by location, water pressure, sun exposure and movement.
How long does waterproofing last?
There is no single figure: service life depends on the system, the quality of the details and installation, exposure to sun and heat, the protection layer and maintenance. The warranty is according to the approved system, manufacturer recommendations and the project agreement.
