Liquid Waterproofing

SIG Design Technology

Liquid Waterproofing
Liquid waterproofing systems provide one of the most cost-effective methods for making a new or existing roof waterproof. Correctly installed and maintained they can provide a long-term life often in excess of 25 years, and in refurbishment situations liquid systems can provide considerable savings on roof replacement costs.

SIG Design and Technology are able to recommend a wide range of liquid roofing products for your projects. Each one has its particular benefits, and SIG can even seek out other specialist products if required on your behalf – view their case studies below for more information.

SIG provide not only a range of premium liquid waterproofing systems to choose from, but also the dedicated support before, during and post install that helps ensure a successful outcome.

Hydrostop AH+ Liquid Waterproofing
The new and improved Hydrostop AH+ is a wet-on-wet, cold applied liquid waterproofing product that’s fully reinforced with a polyester fabric. An extremely versatile and innovative one-component liquid system it offers many benefits including ease of application, fast curing times and with low VOC content it is fume free and virtually odourless. It can also be applied in practically any conditions and at low temperatures. The superior performance of the liquid waterproofing system makes it ideal for new build or refurbishment projects and gives superb results with complex detailing.

Available in two versions, AH25+ and AH15+ use different weight reinforcement fleece and coverage rates and are available with 25 and 15-year warranties respectively. AH+ systems are BBA certified, certified to EN13948: 2007 for Green Roofs and fire tested to meet BS476-3 2004 Hydrostop AH+ Liquid Waterproofing Systems are the latest innovation in liquid roofing technology combining the benefits associated with existing alternative products, to create a new user friendly system.

Unpleasant odours, restrictive weather conditions, differing application processes, multi component systems – combined, these make the successful installation of liquid systems very challenging. Hydrostop AH+ has been developed with these attributes in mind to produce a membrane which is considerate to the needs of the installer.

SIGnature PU Liquid Waterproofing
The SIGnature PU Liquid Waterproofing System is a revolutionary, fast curing, pure elastomeric, hydrophobic, polyurethane flat roofing system available in two product formats.

SIGnature PU-10 Liquid Coating is a single component liquid membrane, single coat application with a 10-year guarantee.

Both SIGnature PU Liquid Coatings can be applied as a single coat with only localised reinforcing as required, creating a bubble-free and durable liquid applied roofing system. SIGnature liquids can be applied all year round above 5°C and are cold applied – no heat or flame required. They offer excellent elasticity and tensile strength and guarantees up to 20 years (product specific) when installed by a DATAC Contractor – a member of our accredited contractor scheme.

Vulkem® Quick System
The Vulkem® Quick System is a crack-bridging, wear-resistant waterproofing system with aesthetic appeal. Its hardwearing and fast-curing characteristics mean that it is particularly suited to high-traffic areas, such as communal walkways, terraces, balconies, and pedestrian bridges. The UV-resistant polyurethane-modified methyl methacrylate (PMMA) system can be applied during the winter at very low temperatures and is guaranteed for 20 years.

The different components that make up the Vulkem® Quick System cure to form a highly-elastic, foot trafficable waterproofing system which is suitable for installation on old or new concrete, tiles, metal, wood, epoxy and other types of existing deck coatings.
