The Lancasters:

A refurbishment project that used waterproofing intelligently is The Lancasters in London. The Georgian terrace was ailing until its £80 million redevelopment into 77 apartments. Its Grade II Listed facades were kept and the interior rebuilt. Three subterranean levels were also created for car parking, gyms, swimming pools and a business centre.
The redevelopment project by Northacre, in conjunction with Minerva PLC, required a high level of integrated waterproofing, as any remedial action would prove highly inconvenient. Nilsson Architects therefore turned to specialist consultant TASC Associates for specification advice.
A range of products from Sika, global manufacturer of building materials, were selected to create the watertight envelope, installed by specialist structural waterproofing contractor Aquarend.

Cornwall Terrace:

For the renovation of eight properties into ambassadorial residences,in one of London’s most prestigious locations, specifiers looked to a waterproofing system that would protect the historic and nationally prominent buildings to the utmost. They chose the market proven Sika 1 Pre-bagged Waterproofing System – a system that has provided undisputed protection for over 100 years.

Oakmayne Properties, working with award-winning architects Tate Hindle and English Heritage,completely redesigned and rebuilt the interiors and renovated the exteriors of the eight properties. Part of this work included the upgrading of its basements to provide more habitable living space for its residents.

The basement refurbishment project was overseen by main contractors Laing O’Rourke working with specialist contractor Aquarend. Providing their expertise to the waterproofing of the basements, they installed the Sika 1 Pre-bagged Waterproofing System, a system Aquarend has used on prestigious basement refurbishments in London many times over.


Beech Cottage
 Sika’s Cavity Drainage System has successfully stopped water from leaking into the basement of a Surrey based private home – keeping the residents and their new second lounge safe and dry.

Following construction, ground water penetrated the new extension via the lightweight block cavity skin due to higher adjacent ground levels. Sika, global leader in specialist building products, was asked to put a stop to the water intrusion with its market leading waterproofing systems.

With the cottage’s lightweight block structure too weak to utilise a waterproofing render system, such as Sika’s renowned Sika 1 Pre-bagged waterproofing system, the company and specialist contractor, Aquarend, worked closely with the client to specify the right solution – Sika’s Cavity Drainage System.
