Case studies

The Gunnery, Kent is a unique and interesting project. United Kingdom’s coast line is littered with abandoned military bases and forts which tell stories of England’s defence to a range of enemies.  Coastal fortifications can date back to 1534 and earlier, with many constructed under the rule of Henry VIII. During WWII the South was deemed as the most threatened part of England by German invasion. Kent is less than 30 miles from…

To waterproof the below ground structure of this project a ‘type C’ waterproofing system (Delta System 500) was installed internally to manage and control any water ingress. Delta MS500 fixed to the walls and Delta MS20 laid across the floor sealed with the necessary tapes. Modular drainage was used to drain any water build up to a bespoke Delta packaged pump station situated within the RC concrete slab on the lower level…

Although primarily designed to waterproof basements, the range of Delta products were used at ground level on a semi-detached property in Hertfordshire that suffered from severe flooding. This is not the first contract where the Delta system has been selected for ‘Flood Recovery’ and Delta has long been highlighting the economic and speed of application benefits for the products in such situations. After the flood at…

As this project was a double level basement a continuous waterproofing system was specified and designed by Delta’s Paul Callaghan CSSW to drain and manage any water ingress that may enter the structure below ground. Firstly a ‘Type B’ waterproofing concrete system was poured against the piles with a ‘Type C’ cavity drain membrane waterproofing system (Delta System) mechanically fixed to the walls of both levels and a floor…
