BC-01 Combined Waterproofing Reinforced Basement within Contiguous Piles

Newton-Solution-BC-01

Newton Waterproofing Index Score

This solution has the capability of achieving an NWI score of 3.6, by employing 1 form of waterproofing (Type A – Barrier Protection) to prevent ground water passing through the structural elements of the building to ensure that the desired internal environment is achieved. 

Newton Waterproofing Index - 2.3-3.6

Recommendations & Standards

Type B, integrally waterproof reinforced concrete structures, should be designed to BS EN 1992 (Eurocode 2) and placed correctly with good compaction to remove all air pockets, and where all joints are correctly waterproofed. Poor workmanship resulting in poor construction will have an adverse effect on the final NWI score.

The structure should be constructed to ensure that it is able to resist the stresses imposed by the ground water pressure and be engineered or of sufficient mass to resist flotation. The installation of re-usable injection waterbar systems should be considered.

For more information about NWI scores and how they can help with your project design, read our page explaining the Newton Waterproofing Index and how it works.

Type B – Prevent Water Ingress Through Construction Joints and Service Penetrations

Newton-Solution-BC-01-NWI-scoreInstall the high-grade, hydrophilic Newton 315 Polymer-Waterbar at the centre dimension of joints to provide the most protection to the key critical construction joint. 315 Polymer-Waterbar swells up to 9 times its original size when in contact with water, sealing the joint fully and reliably.

Type C – Isolating the Internal Habitable Space and Fixtures and Fittings from Dampness and Water Ingress 

Apply the Newton CDM System internally, including a safe means of drainage to remove any ingressing water. The Newton CDM System comprises of a cavity drain membranes, drainage, pumps and control systems and is ideal for projects where a completely dry internal environment is required.

Further Information

To improve the NWI score, improve the waterproofing design by adding a Type A system as per Newton Solution ABC-01.
