One of the world’s oldest and most traditional waterproofing materials, mastic asphalt is a truly versatile performer, outlasting other materials and proven time and time again on everything from sealing dams to flooring, flat roofs to sports facilities,walkways to balconies and car parks to bridges

Successfully used to provide unbeatable protection from water penetration for centuries, in recent years mastic asphalt has been reformulated to include advanced polymers for increased durability, combining its traditional strengths with modern technology.

Mastic asphalt is highly resistant and robust enough to withstand all types of weather situations and attacks from thermal shock (rapid temperature changes), which are a frequent source of break down in many other types of membrane.It’s also non-toxic and non-flammable.

Its durability and seamless application means that it is one of the few membranes able to handle consistent heavy foot and vehicular traffic, including from Heavy Goods Vehicles, and still maintain its waterproof integrity. With no application too tricky, it is also easy to repair should alterations or damage occur.

Another major advantage with mastic asphalt is that it can be laid at speed, reducing the project costs significantly. It also cools very rapidly, allowing foot traffic within two to three hours, dependent upon ambient temperature.

Providing such excellent wear against the extremes of weather – and with a life expectancy of 50 years and more – the waterproof membrane is fast becoming the material of choice for a manner of different buildings including, schools, offices, shopping centres, hotels and even churches.

Mastic asphalt has one further advantage over other types of waterproof membrane – it is carbon neutral – a massive bonus for any building owner anxious to show their green credentials and, when it has reached the end of its useful life, it can be recycled or used as roof screed, minimising the impact on the environment.

Highly cost-effective, mastic asphalt offers lower installation costs than many other types of membrane. Its versatility makes it the ideal choice, so whether it’s a 31 mile bridge in Hong Kong or St Paul’s Cathedral, this market- leading product is revered across the world.
