Cold applied liquid membrane system for uninsulated flat roofs.
AlphaGuard BIO is ideal for providing a durable, fast curing, low odour, waterproof coating on any new build or refurbishment flat roof.
AlphaGuard BIO is a unique polyurethane, two-component, liquid applied membrane with a high bio-based (castor oil) content that can be used to weatherproof any new build or refurbishment flat roof. With its extremely low odour, ease of application and rapid curing properties, the AlphaGuard BIO systems are an ideal specification for highly sensitive areas, such as hospitals and schools where pungent odours should be avoided.

System performance | Guidance for specification option: AlphaGuard BIO systems possess a variety of independently assessed accreditations for performance such as British Board of Agrément, European Technical Assessment and a Broof(t4) fire rating under BS EN 13501-5:2016 fire classification of construction products and building elements. AlphaGuard BIO systems comply with the performance guidelines set out in relevant UK Building Regulations, BS6229:2018 Flat roofs with continuously supported flexible waterproof coverings, and LRWA codes of practice. AlphaGuard BIO membranes offer exceptional low odour application with an enhanced environmental profile. |
Preparation | |
Horizontal work | AlphaGuard BIO primer (Direct Coating).Guidance for specification option: The specific AlphaGuard BIO primer type is subject to adhesion tests and the proposed substrate material. Standard AlphaGuard BIO primers: • AlphaGuard BIO WB Primer:
• AlphaGuard C-Prime:
• AlphaGuard M-Prime:
|
Skirtings and vertical work | As Horizontal work. |
Liquid-applied waterproofing | |
Type | AlphaGuard BIO.Guidance for specification option: A fully reinforced, two-component, polyurethane liquid applied membrane with catalyst technology. AlphaGuard BIO has exceptional low odour properties and provides a robust waterproofing layer that can easily cope with normal levels of structural or thermal movement. AlphaGuard BIO Basecoat is hand-applied in two separate coats with AlphaGuard 225g Reinforcement installed between each coat. AlphaGuard BIO Basecoat should be applied at a rate 0.8 kg/m² achieving a final coverage of 1.6 kg/m². To complete the membrane system, AlphaGuard BIO Top Coat is hand-applied in a single coat at 1.2 kg/m². |
Reinforcement | AlphaGuard 225g Reinforcement.Guidance for specification option: A strong, chopped strand matting, glass fibre reinforcement that provides enhanced strength to liquid applied membrane systems. AlphaGuard 225g Reinforcement is applied between separate coats of AlphaGuard BIO Basecoat. AlphaGuard 225g Reinforcement should be carefully embedded into the base 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. TremTrim.Guidance for specification option: TremTrim is a prefabricated GRP edge trim that is specifically designed for multiple flat roof waterproofing types. Compatible with various Tremco reinforced bitumen membrane and liquid applied membrane systems, TremTrim provides an effective termination of the specified waterproofing systems at the perimeter edge. 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. |
