The Caltech QC range comprises cold applied, reinforced PMMA waterproofing systems for roofs, balconies, terraces and walkways. The wet-on-wet application process incorporates polyester fleece reinforcement, reducing installation time and the risk of inter-coat contamination.
The range includes primers, air and vapour control layers (AVCL), warm and non-combustible thermal insulation options, and ancillary components.
The range includes:
The Caltech QC range features a catalyst-controlled cure to form a seamless, fully bonded membrane that simplifies installation while providing crack-bridging performance, rapid curing and durable protection. The liquid-applied formulation can be applied by roller or brush, forming a self-terminating membrane that allows efficient detailing around vertical upstands, penetrations and complex junctions without the need for mechanical termination bars. Caltech QC is suitable for a wide range of roofing applications and can be integrated with other Alumasc waterproofing systems to facilitate the waterproofing of complex details, transitions and interfaces.
Available with a range of decorative, textured and anti-slip finishes, the Caltech QC Balcony Plus system can be tailored to meet project-specific aesthetic, durability and slip-resistance requirements.
