Case studies

To fulfil the requirements of BS8102:2022 and BS 8485:2015+A1:2019 a strategy to develop a specification which combines structural waterproofing and ground gas protection were required for this refurbishment project.

The project involved creating additional living space to an existing mid terrace Victorian property in W12.  The site of the property, whilst not being located on contaminated land was identified as being potentially at risk, it was near what is classed as contaminated land (an old brick yard).

To satisfy Building Control requirements gas protection measures were required to meet BS 8485:2015+A1:2019.

Delta Registered Installer, T W Read Waterproofing Ltd have extensive experience in providing professional design and installation of waterproofing systems for existing and new build structures.

The Scope of this project was to provide a structural waterproofing solution to a large basement that had been formed below a residency in Streatham, South West London. These works were originally undertaken by a basement company who had ceased trading. Whilst the excavation works had been completed, no waterproofing system had been installed. 

The scope of the project was to facilitate a combined waterproofing solution for a 2,000m² luxurious subterranean space which includes a double-level basement that will accommodate a cinema room, spa wing and swimming pool, changing, and screening rooms, servery, storage & laundry wing, plant rooms and other accommodation.

Delta Registered Installers, Knowles were appointed as principal contractor to collaborate with the architects to fulfill the role of Waterproofing Design Specialists in providing a reliable, watertight solution for this £100m project.

Delta Registered Installers, Abtech (UK) Ltd were called upon to give assistance on a particularly technically complicated project where approaches to waterproofing design and installation had been incorporated, however the system had failed.  For a great remedial waterproofing outcome, seek assistance from an experienced waterproofing company to inspect your site and carry out the remedial work.

The property when built had a Type C, cavity drain membrane systems incorporated (not a Delta System), however there was no basement drainage incorporated into the design to manage water ingress.
