Combo Roof System

Combo roof waterproofing is an advanced multi-system waterproofing solution designed to provide superior protection for roof surfaces by combining two or more compatible waterproofing materials in a single integrated system. This approach is used to enhance durability, improve redundancy, and ensure long-term resistance against water ingress, thermal movement, UV exposure, and structural stress.
Typically, combo systems may include a combination of polyurethane foam, RBE / acrylic coating, screed, and the final PU top coat.
Depending on project requirements and site conditions. Each component is applied in a specific sequence, where membranes provide the primary waterproofing barrier, and liquid coatings or reinforcements enhance detailing, flexibility, and joint protection. This layered system ensures complete coverage of critical areas such as joints, corners, penetrations, and parapets, which are most vulnerable to leakage.
Combo roof waterproofing is especially suitable for flat roofs, podium decks, terraces, and exposed concrete surfaces where high performance and extended service life are essential. It offers excellent resistance to ponding water, UV radiation, temperature fluctuations, and structural movement, making it a reliable and durable solution for residential, commercial, and industrial projects.

Application Procedure

Surface & Condition Check

Thoroughly inspect substrate condition and environmental factors including wind speed, humidity levels, and surface moisture content, ensuring all parameters comply strictly with manufacturer’s specifications before proceeding.

PU Foam Mixing & Layered Application

Precisely spray-apply the polyurethane foam in multiple passes to achieve the required thickness, creating a seamless, self-bonding insulation layer across the entire deck.

Elastomeric Waterproof Base Coat

Apply a UV-resistant protective base coat over the cured foam to seal the surface and provide an immediate waterproof secondary shield.

Geotextile Installation & Slope Formation

Install a separation layer of non-woven geotextile followed by the formation of precise slopes using lightweight screed to ensure efficient water drainage.

Concrete Screed Placement & Finishing

Lay the protective concrete screed to specified gradients, providing a durable walking surface and mechanical protection for the underlying layers.

Joint Sealing & Angle Fillet Preparation

Detail all critical areas, including expansion joints and wall-to-floor junctions, with specialized sealants and cementitious coving to eliminate leak-prone corners

Final Cementitious Waterproof Coating

Apply the final, heavy-duty waterproof membrane over the finished screed and parapets for a complete, multi-layered customization of the roof’s defense system.

Material Composition

Integrates high-density, closed-cell polyurethane foam with a secondary layer of fiber-reinforced cementitious or liquid-applied membranes to create a robust, monolithic barrier.

Thermal Performance

Delivers exceptional insulation with low thermal conductivity, significantly reducing heat transfer into the building and optimizing HVAC energy efficiency.

Weather Resistance

Engineered to withstand extreme temperature fluctuations and prolonged UV exposure while maintaining a seamless, watertight seal against heavy rainfall and ponding water.

Durability & Flexibility

Combines high compressive strength to handle structural loads with superior elastomeric properties that accommodate natural building movement without cracking.
