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 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. 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.

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. Ideal for new build or refurbishment projects and gives superb results with complex detailing.

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
SIGnature PU Liquid Waterproofing System is a revolutionary, fast curing, pure elastomeric, hydrophobic, polyurethane flat roofing system available in two product formats.
SIGnature PU-20 Liquid Coating Kit comprises two components which when mixed together create a single coat application, rapid curing liquid roofing membrane which can offer a 20-year guarantee.

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.

SIGnature Edge Coating System
Plastisol or PVC-coated metal sheeting which has been cut on site exposes a cut edge of bare metal, mainly at overlaps and eaves. The coating will, over time, peel away from the untreated edge and corrosion follows through weathering and capillary action of water held in the lap.

SIGnature Edge Coating System has been developed to protect the cut edges of Plastisol or PVC-coated metal sheeting used in roofing and cladding applications. When properly installed by a DATAC accredited contractor the products are guaranteed for 10 years, effectively lengthening the lifespan of metal sheeting. SIGnature Edge Coating System is also suitable for the repair of penetrations and guttering.

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.

LIQUIROOF
Available exclusively from SIG Design & Technology LIQUIROOF interlocking PIR boards deliver a super-flat surface ideal for liquid and flat roofing systems. Liquid waterproofing coatings are typically between 1.25 to 2mm thick meaning even the most minor imperfections in the substrate surface can create alignment issues and stress points on the outer surface coating. LIQUIROOF fully supported PIR insulation boards interlock on all 4 sides, from top to bottom, to create a strong and solid surface with no raised edges, misalignment or gaps.

Faced with a lightweight 8mm OSB 3 panel on the topside, LIQUIROOF panels are designed for use on old or new boarded structures. The polyurethane rigid foam insulation core provides maximum insulation with minimum panel thickness. The serrated edges on the boards slot together easily to cover large uneven surfaces, and with minimised alignment time are quick to install.
