Liquid-applied waterproofing | |
Type | AlphaGuard FC LOW. Guidance for specification option: A highly elastic, fully reinforced, polyurethane modified, benzyl methacrylate liquid applied membrane that cures in minutes with an advanced catalyst activation and extremely low application odour. AlphaGuard FC LO has exceptional elongation and crack bridging properties offering a robust waterproofing layer that can easily cope with normal levels of structural or thermal movement. AlphaGuard FC LO is hand-applied in two separate coats with AlphaGuard 225 g Reinforcement installed between each coat. The first coat should be applied at a rate 2.1 kg/m², reinforcement applied, and a second coat of 1 kg/m² to achieve an overall waterproofing layer of 3.1 kg/m² (minimum 2.3 mm dry film thickness). Catalyst mixing is typically 4% by weight (20°C or below) but can be adjusted for lower ambient temperatures. |
Reinforcement | AlphaGuard 225 g Reinforcement. Guidance for specification option: A strong, chopped strand matting, glass fibre reinforcement that provides enhanced strength to liquid applied membrane systems. AlphaGuard 225 g Reinforcement is applied between separate coats of AlphaGuard FC LO. AlphaGuard 225 g Reinforcement should be carefully embedded into the initial coat, lapped by minimum of 50 mm, and laid flat without creases, air pockets or prominent fibres. |
System accessories | TremDome. Guidance for specification option: A traditional domed style rooflight that includes a thermally broken insulated kerb with excellent natural light transmittance properties. TremDome rooflights come with a variety of ventilation accessories and can be operated manually or electronically. Design is subject to survey or client requirements. TremDrain. Guidance for specification option: Gravity drainage outlets that have an integral membrane flange for sealing flat roof membranes. TremDrain outlets are manufactured from aluminium, are suitable for all roof types and offer excellent flow rate. Type, size, and design is subject to survey or client requirements. TremClip. Guidance for specification option: Lightning protection systems are frequently installed to buildings to avoid damaging and costly lightning strikes. TremClip has a threaded securement base that includes a separate retaining clip to secure lightning conductor tape at predefined centres across the roof. TremFlash. Guidance for specification option: A1 non-combustible secondary cover flashing manufactured from soft and workable zinc alloy. Primarily used as lead substitute in flat roof details such as wall chases or abutment flashing. Ilbruck SP510. Guidance for specification option: General purpose low modulus sealant that is silicone free and cures to form a tack free surface. TremSeal mastic can be used to enhance the waterproofing integrity of a wide variety of detailing situations. TremSafe. Guidance for specification option: TremSafe is a range of bespoke roof top safety items such as a fall prevention guardrail system, access ladders, and up and over service platforms. All TremSafe items are manufactured with robust galvanized steel and designed to overcome any specific site condition. TremDuct. Guidance for specification option: TremDuct is a prefabricated, cable penetration unit manufactured from stainless steel and rigid PVC that includes an integral membrane flange. TremDuct cable penetration units are specifically designed to create a robust and weatherproof service penetration for cables or conduits passing through flat roof constructions. TremVent. Guidance for specification option: TremVent is a prefabricated ventilation unit manufactured from stainless steel and includes an integral membrane flange. TremVent ventilation units are designed to create a flat roof penetration that can be effectively sealed to the primary waterproofing membrane. These roof mounted ventilation units are a suitable choice for new build installations or can be used to renew existing vents during flat roof refurbishment. Manufacturer guidanceAs required. |
