Creating a New Community Centre, North London

When HSP Architects and Price & Myers wanted to transform a listed commercial basement in Temple Fortune to create a new community centre, they needed to look no further than Newton Specialist Contractor Arti Construction to perform the waterproofing.ning three of the walls were either fully or partially below-ground and suffering from water penetration. Arti recommended the Newton CDM System, as it is the most safe and reliable form of waterproofing that would deliver a completely dry internal space and cause the minimal amount of disruption to the Listed structure.

The basement, part of a four-storey Listed building, was built into a hillside, meaning that three of the walls were either fully or partially below-ground and suffering from water penetration. Arti Construction worked with the design team at an early stage to design a waterproofing solution.

With existing Listed basements such as this one, Arti Construction were quick to recommend a Type C cavity drain waterproofing solution in the form of the Newton CDM System. Type C waterproofing is the safest and most reliable form of waterproofing that will deliver a completely dry internal space, whilst also causing the minimum amount of disruption to the Listed structure.

Before Arti could proceed with the installation, they first had to re-level the existing concrete slab in order to provide a flat and stable floor.

With the structure fully prepared, Arti could then proceed with installing a full cavity drain waterproofing system. This consisted of installing Newton 508 with minimal MultiPlug fixings to the walls and floors to capture the ingressing water. The water is then directed via Newton Basedrain channels to a Titan-Pro sump chamber, for removal by dual NP400 clean water pumps.

The complex basement space included existing columns, windows and an internal staircase which all had to be factored into the waterproofing design.

Regardless of this, Arti Construction completed the 280m2 installation within budget in just one week, delivering a reliable Type C structural waterproofing system that is also compliant with British Standard 8102:2009.
