Delta basement waterproofing for London Synagogue

Delta basement waterproofing for London Synagogue

Delta Membrane Systems provided a basement waterproofing system for a new build basement for a North London Synagogue.

Synagogues are places for the Jewish community to worship, they are also used as a place to study and often act as a centre for the community.

Delta were first approached at the design stage of the project. During on-site attendance it was noted that the hydrostatic head of water pressure in this area was phenomenally high and that the waterproofing design would need to reflect this.

Delta’s Technical Consultant, Paul Callaghan suggested incorporating into the design the Delta Bespoke Sump Pump range.

Delta’s Bespoke Sump Pump range would be able to remove large volumes of ground water in the event of an unexpected defect in the structure, foul and grey waste.

Delta’s Sump Pumps are designed and manufactured within the United Kingdom and are capable to withstand hydrostatic forces encountered in all demanding and unsympathetic applications.

Locations of the sump pump units were suggested during the design phase and were installed by the main contractors under the supervision of Delta. By incorporating sump pumps at the design stage, it allowed for project team to work together to create and share a range of project documentation with the benefit of interconnectivity which in turn created better project decisions during the correct stages of the project.

The design was further enhanced by the incorporation of a high-water level alarm which is WIFI enabled offering predictive data to our operation centre monitored 24/7 and a duplex control panel (the powerful Dual V6 pumps were factory set to activate at different levels. One V6 pump being the primary and the secondary pump acting as a back-up).

With the Synagogue basement being a new build would benefit from an application of Koster Polysil TG 500 (an anti-lime coating/surface primer) which would reduce the risk of excess free lime leaching out of the concrete during the curing process. This free lime, if untreated, can enter the Cavity Drainage System which can impede the flow of water and cause sump pump failure.

The client confirmed Delta’s expertise and on-site attendance exceeded expectations. The client congratulated Paul on his understanding of expected performance and his ability to explain the reasons for his waterproofing design.

Delta were able to review the objectives of the project and present solutions resulting in the Shul and rooms within its basement remaining dry, habitable and fit for purpose.
