Future Proofing Waterproofing Multi Level Commercial New Build Structure

OVERVIEW

Delta’s Structural Waterproofing Consultant, Paul Green, CSSW alongside Delta’s MD, Kevin Dodds, were appointed to the design team to collaborate with the Architects, Engineers, Main and Sub-Contractors to fulfil the role of Waterproofing Design Specialists in providing a reliable, watertight solution for this substantial project.


The large-scale basement project consists of a 4-storey deep

basement located close to the River Thames in Central London.


The proposed subterranean space would offer multiple usage. This complex project required a waterproofing design which is, able to cope with intermittent/regular hydrostatic pressures created not just by groundwater, but also geographical tidal impacts from the river Thames and potential stress challenges caused by the surrounding infrastructure such as heavily trafficked railway lines in the development’s vicinity.


Structures that experience a high level of vibration from

surrounding infrastructure can, over time, have a high propensity to suffer cracks, which could lead to failure of some waterproofing solutions, so therefore careful considerations should be incorporated into the overall waterproofing design from those aspects and, the impacts these factors can have on an elected waterproofing system.

Delta’s design philosophy rotated around creating a robust and suitable waterproofing design, the structure design, a continuous system, sequencing and installation, future maintenance, and serviceability, whilst able to fulfil requirements set out in BS 8102:2022 Protection of below ground structures against water ingress. Code of practice. The British Standard which governs waterproofing of substructures.
