Services
Single Ply Roofing
Single ply roofing uses synthetic polymer membranes for durable, flexible solutions with over 40-year life expectancy. Our systems accommodate adhered, loose-laid, or ballasted applications, featuring hot-air welded seams stronger than the membrane itself. Available in custom colours, these systems replicate traditional metal roofing aesthetics at reduced costs while offering self-cleaning surfaces and recyclability benefits.
Structural Waterproofing
Hot melt waterproofing provides monolithic membranes with self-healing properties and 100% substrate adhesion. Our BBA-accredited systems include 6mm thick layers with reinforcement, suitable for inverted green roofs and podium structures. Installed by approved contractors, these solutions operate at temperatures down to -18C and carry 20-year warranties, eliminating concerns about lap failures or water tracking.
Green Roofing
Green roofs combine ecological benefits with functional performance, featuring extensive systems weighing as little as 65kg/m. Our solutions support biodiversity through sedum plants and low-maintenance substrates, reducing stormwater runoff and urban heat island effects. Systems include pre-cultivated mats and custom planting options, compatible with both new builds and refurbishments while meeting FLL design standards.
Built Up Felt Systems
Multi-layer bituminous systems offer proven reliability with BBA-certified 30+ year lifespans. Our torch-on and flame-free membranes suit warm and inverted roofs, featuring polyester/glass fibre reinforcement for tear resistance. Available with various insulation options, these systems maintain stability in extreme temperatures while complying with ISO9000 quality standards.
Liquid Applied Waterproofing
Liquid coatings provide flame-free waterproofing for new and existing roofs, using bitumen, polyester, or polyurethane bases. These systems allow direct application over existing coverings, reducing disruption during installation. Suitable for flat and pitched roofs, they offer rapid curing times and adaptability to complex roof geometries and penetrations.
