The building had suffered from fire damage as well as vandalism over the years and had been left to ruin. During a site visit various considerations were given to what Delta product would be best suited to the job, given the restrictions imposed by the existing structure.

BRE Flood Reilient Test Home

Delta Membrane Systems Ltd

Delta Membranes were delighted to be invited by the BRE in adapting a property which could offer Flood Resilience. A housing unit within the BRE (a Victorian Terrace) was refurbished to demonstrate materials, products and innovations that will make it flood resilient. There are an estimated 5.2 million homes considered at risk from surface, river and coastal flooding. Preventative measures play a key role. The specification for resilience, using the same technology Delta have used for many years in Basements or below ground situations with additional consideration as to how we could adapt this to work in flood situations.

Luxury North London Residence

Delta Membrane Systems Ltd

Delta Membrane Systems Limited was asked to assistance on a particularly technically complicated project. The project in question was a new build luxury property in North London, providing almost 17,000 sq ft of accommodation, over four floors.  High volumes of hydrostatic water pressure was bearing on the structure, which was causing the property to suffer severe water ingress through construction joints. The property when constructed was built at a low level, it sits lower than the neighbouring properties adding to the hydrostatic water pressure issue.  An additional problem was the property had been built without a waterbar/hydrophilic strip.

Waterproofing vaults (using Type C Systems)

Delta Membrane Systems Ltd

Vaults are a common feature of 18th and 19th century buildings in Bath. Originally built to support the cobbled streets above and were a constructional response to the precipitous topography that surrounds Bath, in order to provide a level site. Many of the vaults within historic Bath suffer with water ingress and damp related problems. Incorporating best practice guidance - Type C Waterproofing Systems (BS 8102: 2009) a Type C System was used to keep this historic vault watertight and dry.

Basement Extension

Delta Membrane Systems Ltd

The project was split into 2 phases. Phase 1, waterproofing the exiting basement and Phase 2, retrofit extension to the existing basement to create a luxurious multiuse living area.

The Hub, Hattersley - Leaking Podium Deck

Delta Membrane Systems Ltd

Delta were employed to assist on this leaking podium deck project. Following a full assessment of The Hub and its underground parking facilities it was identified that rainwater was entering the basement car park through the ceiling deck at multiple points. These points included holes that were formed to allow drainage from the surface, movement joints and investigation holes that had been created through the steel rib and concrete deck. Based on “as built plans” a system was designed post construction that would offer the same quality of structural protection had it been incorporated during the build phase.

Public House Cellar Conversion

Delta Membrane Systems Ltd

Delta Registered Installers, Oaks Damp Proofing having previously undertaken work for the client were commissioned to design and install a Cavity Drain Waterproofing system that would meet BS8102:2009 the British Standard for the protection of structures against water from the ground, Grade 3 (no dampness or water penetration acceptable) to the cellar area of The Blonde Hedgehog. The Cellar having been used historically to store beer was not waterproofed historically. Beer cellars are notable for being very cold and wet. For hundreds of years beer cellars were always underground – because underground rooms are generally quite cool.
