London basement waterproofed by Delta Membranes

Delta Membranes recently provided its waterproofing system to make a newly excavated basement at a London mews house watertight.

The London property is sandwiched between to rear gardens of adjacent properties and didn’t offer the opportunity of extending the existing footprint. Excavating under the drive allowed the property’s owner to extend their home without compromising on neither the property’s external appearance or functionality.

Delta’s Waterproofing Design Specialist suggested incorporating Koster NB1 to wall/floor joints. Fillets were created to protect external junctions, using Koster Repair Mortar Plus. The coved fillets were then further waterproofed using two coats of Koster NB1 crystallising mineral waterproofing slurry. 

Delta Membrane Systems Limited has qualified to use the CE mark and hold BBA Agrement Certificate 00/3742. All membrane systems are manufactured in accordance with DIN EN ISO 9001, and EMAS EN ISO 14001.
