Basement Waterproofing for a nursery in Bradford


Products used: Cavity Drain Membrane

Undercliffe Lane Community and Children’s Centre was first set up in 2003 by local people of St Augustine’s Church and nearby residents. Local people felt strongly that there was nothing for them in their community and they wanted this to change. They are now a thriving community project which incorporates a Children’s Centre that has a wide range of activities including a nursery and opportunities for children and adults across the age range.

Undercliffe Lane Community works and Children’s Centre was due for a program of alterations and partial refurbishment during the summer break. Part of the works involved the installation of a lift facility and the provision of through access into a basement classroom. The existing access to the classroom consisted of a damp, untidy basement hallway which needed waterproofing to provide a safe, and dry environment.

Did you know?

‘Broad Ford’, later known as Bradford, was first settled in Saxon times and by the middle ages had become a small town centred on Kirkgate, Westgate and Ivegate.  


Alongside the architect and the contractor, Timberwise designed and installed a Type C (drained protection) waterproofing system with little preparation and the facility for the contractor to dry-line over the waterproofing system which reduced wet-trades in the schedule of works. The cavity drain waterproofing system was installed quickly with little or no disruption to the program, therefore, the works were allowed to proceed unhindered.

What a great opportunity to work with such a caring and community-driven establishment. Through our innovative waterproofing systems, we will make this community centre a warm, dry and safe place for both children and adults to enjoy ”

Cavity Drain Membrane

Benefits of using cavity drain membrane are that it does not require extensive and damaging preparation to the wall surface and that it provides vapour control and when used with humidity control systems is capable of delivering an environment to all levels within a Grade 3 environment to BS 8102:2009

Sump Pump

The cavity drain waterproofing system was designed to drain into adjacent large basement rooms which were at a lower level and had submersible sump pumps recessed in the floors. Attention to detail with designing waterproofing systems is critical – Timberwise technicians ensured that service penetrations through the waterproofing membrane were treated effectively and that fixing points did not create any problems for the contractor. All joists were fully sealed using butyl tape and fixing points were sealed using gasket grommets to the underside of system fixing components.


Under the Code of Practice which dictates waterproofing design (BS 8102:2009 – The code of practice for protection of below ground structures against water from the ground), it is critical to design and consider future maintenance into a waterproofing system. Timberwise designed into the specification and installed cleaning ports to allow future maintenance of the waterproofing system and if required inspection of the cavity drainage system at the Community Works Nursery & Children’s Centre.

The system offers support alongside flexibility and working in conjunction with the Maintenance Manager, Timberwise carried out all works in the summer holidays as to minimise disturbance to the nursery.
