Cold Applied Liquid Waterproofing
Dura-Walk
Dura-Walk is a liquid walkway and balcony waterproofing system, a polyurethane modified methyl methacrylate liquid coating engineered for walkways, balconies, and high-traffic surfaces. Rapid cure times and crack-bridging properties deliver trafficable waterproofing (topcoat UV-aged to 1200 MJ/m² at 50°C, EOTA TR-010) suitable for concrete, asphalt, metal, existing coatings, bitumen membranes, and new warm roofs.

Why Choose Dura-Walk?
Pedestrian traffic performance
Designed for roofs and external areas subject to regular foot traffic, providing a durable waterproofing and wearing surface within a single system.
UV and weather performance
The finished surface is UV-aged tested to 1200 MJ/m² at 50°C (EOTA TR-010) and formulated for rainfall and seasonal temperature variation as part of the complete system build-up.
Crack-bridging capability
The elastic membrane accommodates normal substrate movement while maintaining continuity of the waterproofing layer.
Surface finish options
Available with a range of aggregate finishes and colour options to suit access routes, balconies, terraces, and wayfinding requirements.
Dura-Walk Liquid Walkway and Balcony Waterproofing System Build-Up
Dura-Walk comprises three essential components working together to create durable, trafficable waterproofing for balconies and walkways in commercial and residential applications.
Dura-Systems Primer
Treat and Prepare
A range of Dura-System Primers are available to treat and prepare various surfaces, ensuring a strong and watertight bond of the waterproofing membrane.
Dura-Systems Membrane
Dura-Systems Membrane is a polyurethane modified, thixotropic methacrylate resin system that is suitable for creating watertight membranes on a wide variety of substrates. The formulation Dura-Systems Membrane can also be used for coating on rising or very steeply inclined surfaces.
Dura-Systems Membrane Detail
Membrane Detail is a polyurethane modified, thixotropic methacrylate resin system that is suitable for creating watertight membranes on a wide variety of substrates. The formulation Dura-Systems Membrane Detail is designed for complex detailing where using Grip Soft Polyester reinforcement would not be suitable. The resin is reinforced due to the formulation containing embedded fibreglass stands and has an increased viscosity to help application on vertical, rising or very steeply inclined surfaces.
Dura-Systems Membrane Thix
For Creating Watertight Membranes
Dura-Systems Membrane Thix is a polyurethane modified, thixotropic methacrylate resin system that is suitable for creating watertight membranes on a wide variety of substrates. The formulation Dura-Systems Membrane Thix is specifically designed to be mixed with Dura-Systems Membrane to increase the viscosity of the coating to be used for coating on vertical, rising or very steeply inclined surfaces.
Grip Polyester Soft
Reinforcement
Grip Polyester is a strong, elastic, polyester reinforcing fabric. Each is a lightweight material ideal for use with cold-applied mastics. Grip Polyester Soft differs from Grip Polyester Firm by conforming more easily and readily to irregular shapes and surfaces, making it ideal for use over irregular surfaces.
Dura-Systems Top Coat with Quartz Anti-Slip Aggregate
Resistance to Water Interaction
Dura-Systems Top Coat is a reactive solvent-free, low-viscosity, virtually non-yellowing 2-component methacrylic resin offering resistance to water interaction. It serves primarily as a slightly elasticised and unpigmented Top Coat on sprinkled coatings in wet areas. In the Dura-Walk system, the top coat will have a mineral or natural quartz aggregate broadcasted into it at the specified rate to achieve an anti-slip finish. This can be applied to walk ways, balconies or stairways.
