LANGLEY has been supplying high-quality systems for more than 50 years. As part of our commitment to high quality sustainable and long-lasting systems, the Langley PU liquid waterproofing system has been developed to the same exceptional standards which can be expected from us.

Offering guarantee lengths of 20 and 25 years, we are excited that our new liquid technology allows the application of a 25-year system in just two coats. This significantly decreases install time compared to many other liquids in the market where a three-coat system is required.

Langley PU is a solvent-free, polyurethane coating system comprised of primers and liquid-applied membranes and is compatible with the huge range of accessories, rooflights and sustainable solutions on offer. Perfect for sensitive or occupied sites, the low-odour liquid can be used on occupied buildings such as schools or hospitals. It provides monolithic, flexible, durable and long-lasting protection.

Features & Benefits

Low Odour 

Langley PU is a leading liquid roof waterproofing system that uses innovative technologies to deliver a safer, low-odour, user-friendly experience for sites where fumes can be hazardous, such as schools, pharmaceutical and food/beverage manufacturing sites, hospitals, commercial offices and retail units. 

Durable

Polyurethane technology delivers a tough surface, suitable for irregular foot traffic without additional protection.

 

 

Non-Toxic 

Our new PU carries the same warning labels as a bottle of washing-up liquid. Kind to the planet and safer for installers, with no more serious health or environmental hazards on the labels.  

Seamless 

Once applied, Langley PU provides a seamless, monolithic and waterproof barrier which allows surface water to discharge freely from the roof. 

Fast Curing  

Langley PU is already a fast-curing system. With catalysts available to accelerate the cure time during winter months, the speed of installation remains consistent throughout the year. 

Ponding Water Resistant 

Langley PU is highly resistant to ponding water, providing excellent protection even where small amounts of water remain on the roof. 

Quick Installation 

The two-coat system dramatically reduces installation times. 

Minimal Waste 

Roof repairs can be carried out without removing the existing membrane, minimising disruption and reducing waste to landfill.  

Cold Applied 

No need for hot works or naked flames. 

 

The Langley Guarantee

Our guarantees set the benchmark within the industry, with a single-point independent Insurance Backed Guarantee (IBG) of up to 25 years that covers design, workmanship, materials and consequential loss.
