About GRP Tankworks

GRP Tankworks LTD is a two-person specialist team based in London N5. We install and look after GRP sectional cold water storage tanks for building owners, facilities teams, contractors and tank manufacturers.

Our story starts in 2018 at DOK Tanks, building GRP sectional tanks on site for Dewey Waters and Nicholson Plastics (now Tricel). In 2024 we set up GRP Tankworks LTD, and under our own name we've built Tricel panel tanks and, for the past six months, Balmoral tanks.

We build tanks up to 3m deep, from the base bearers up to the final connections, in plant rooms, basements, rooftops and outdoor sites. We hold JIB PMES System Tank Installer cards and confined spaces training, and we're public & employers' liability insured. We work across London and the South of England, and further afield for the right job.

We keep things straightforward: we turn up when we say we will, work tidily and safely, and leave you with a sound, watertight tank.
