Newton Specialist Contractor Arti Construction got involved at an early stage in this new-build project in Golders Green, North West London, to construct an office basement and 4-storey dwelling containing 7 new flats.

The Project

Arti worked alongside Landmark Architecture and Barnard Associates structural engineers. They faced the challenge of excavating and waterproofing a 330 m² basement 3.5 metres deep. They also managed restricted site access and a tight schedule.

The Solution

Arti Construction have been building, renovating, converting and remodelling properties in London since 2002, so they soon got the site up and running with a 40-tonne piling rig installing 267 secant piles. Once the team removed a total of 1,700 cubic metres of earth and clay, they began the waterproofing.

Arti required a completely dry office environment, choosing an external Type A system. They also used an integrally waterproofed Type B concrete structure, and an internal Type C system. They began with Newton 403 HydroBond beneath the slab and against the secant piles. The team completed the Type A solution by applying Newton 104 crystalline solution to the tops of the piles. Newton 314-BG bentonite granules were also used around the pile caps.

To provide a watertight Type B concrete structure, Arti then installed Newton 315 Polymer-Waterbar to all construction joints in the concrete slab and walls.

Once the project was ready for Arti Construction to return to the site, the specialist team installed the maintainable and robust internal Newton CDM System.

The Result

Despite many challenges, including a tight timescale, Arti Construction delivered the project on schedule. They also managed extremely restricted access and Covid-19 social distancing rules.
Arti completed the Type A, B, and C waterproofing to an impeccable standard.
