Type A System – Newton – External Waterproofing

BASEMENT

Type A System – Newton – External Waterproofing

Arti Waterproofing were 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.

Working alongside Landmark Architecture and Barnard Associates structural engineers, Arti were faced with the challenges of excavating and waterproofing a 330m2 new basement at 3.5 metres deep, whilst also coping with very restricted site access and a tight timescale.

 

Project:


As a completely dry office environment was required, Arti chose an external Type A system with an integrally waterproofing Type B concrete structure. They began with Newton 403 HydroBond beneath the slab and against the secant piles. The Type A solution was completed with the application of a Newton 104 crystalline solution to the tops of the piles, and Newton 314-BG bentonite granules to seal 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.
The waterproofing will eventually be finished with an internal Newton CDM System once the project is ready for Arti Waterproofing to return to site.

 

Outcome:


Despite facing many challenges, including a tight timescale, extremely restricted access, and Covid 19 social distancing rules, Arti waterproofing delivered the impeccable Type A and B waterproofing to the agreed project programme.
