Summary

Failed waterproofing on open roof needed to be replaced with a new multi-layer combo roof: insulation, seamless membranes, and technical coatings for resilient, UV-stable, and fully watertight performance. Previous patch repairs and membrane overlays had failed to address underlying slope and coverage issues—leading to recurring leaks and rapid deterioration.

Technical Diagnosis

Failures due to inadequate slope, cracks near outlets, UV breakdown of prior system, and incomplete coverage at interfaces. Complete solution needed re-leveling, improved joint detail, and robust, weather-resistant finish layers.

Implemented Solution

Thorough surface preparation including cleaning, securing of electrical conduit cores, repair of cracks, and protection of adjacent surfaces

Spray application of high-density polyurethane foam in controlled layers, penetrating cracks and leveling surfaces to form a seamless insulation and waterproof barrier

Dual-layer liquid bitumen membrane application providing protection with excellent adhesion and flexibility to bridge substrates movement

installation of geotextile layer, reinforced concrete screed with proper slope, preparation of angle fillets, and cementitious coatings for watertight finish

THE RESULTS

No leaks or dampness; full surface restoration

UV-resistant, long-life protection guaranteed
