A Much Needed Change for Acton

Acton Gardens encompasses 52 acres which places it in the top five largest developments in the capital. This £660m investment will be complete in 2026, delivering 2,500 new homes just a stone’s throw from Acton’s new main line Crossrail station. When complete, Acton’s desirability, which has previously been in short supply, is expected to grow significantly. Richard Cherry, Deputy Chairman of Countryside Properties says, “Our over-arching vision is to transform the South Acton Estate into a highly sought after, sustainable, residential community that all residents are proud to live in.”

Gas-Proofing with PUDLO

Due to the size of Acton Gardens, it is being completed in a number of phases, with PUDLO chosen as the trusted system for waterproofing. PUDLO’s dual system, which incorporates membrane into the traditional waterproof concrete solution, is compliant with NHBC’s rigorous standards. The system was installed on a number of the building phases, and gas membrane was used for much of the project as ground gases including radon and methane were present on site.

PUDLO’s Use throughout Acton Gardens

PUDLO has been used in huge areas throughout Acton Gardens, including critically dry grade 3 areas such as residential slabs and walls and grade 2 areas such as the underground car parks. PUDLO was poured and membrane laid in lift pits and basement areas up to the ground floor level.

Consultation between PUDLO, the main contractor and consulting engineers took place in the early stages of the design phase. PUDLO’s dedicated CAD design team was on hand to offer advice and guidance on the waterproof and gas-proof elements. This team created bespoke drawings and details for Acton Gardens, ensuring the dual system would fully serve its purpose – keeping the development free from gas and water ingress.
