Basement Tanking

Basement Tanking

Tanking Walls is a simple way to create extra living or storage space in your basement
Many houses have basements, cellars and vaults that were never designed for modern living. They can suffer from rising damp and penetrating damp and even flooding.
As a result they are not being used to their full potential. BWD offers a range of basement waterproofing and tanking systems that can transform a damp, dank basement into a dry and habitable living space.

Basement Tanking Solutions

To create a livable space beneath your home we offer both Cementitious Tanking and waterproofing using Cavity Drain Membranes solutions. We will sometimes combine both damp proofing systems to waterproof a basement.

Our surveyor will inspect your basement and discuss your needs.

A basement waterproofing system will be designed specifically to meet your requirements.

Cementitious Tanking

Cementitious tanking utilizes a system of cement based waterproof coatings to prevent penetrating damp caused by capillary movement of water moving through earth retaining walls.
The tanking coatings can be plastered to provide a smooth surface to decorate.
Cementitious tanking is used in situations where there is no free flowing water or risk of flooding and in small areas where there is an
isolated damp problem.


Benefits of cementitious tanking

Can be used in small areas and on convoluted surfaces.
Does not require a drainage system, sump, and pump or an annually servicing.

Waterproofing with Cavity Drain Membranes 

Cavity Drain Membranes utilize a studded membrane to line the walls and floors to provide a dry internal surface.
The walls can then be dry lined or plastered, and the floors can be screened or overlaid with chipboard or tongue and groove flooring.
Sealed systems are used in conjunction with drainage or sump and pump where there is active water or flooding.
Ventilated systems are used where there is no visible water and in situations where conventional damp proofing methods are inappropriate.


Benefits of Cavity Drain Membranes

No need to incur expense and mess removing existing sound plaster (soft plaster shall be removed).
Redecoration can normally be carried out quickly as there is no need to wait for the system to cure.

How to waterproof a basement/cellar?

To waterproof your basement with the DELTA system there are two main components.

  1. Cavity drain membranes (dimpled/studded plastic sheets) which wrap the walls and floors to keep your finished wall dry.
  2. Drainage & sump pumps to drain the collected water to an existing drainage system, manhole or soak away.

The cavity drain membranes are fixed to the wall with our various fixing plugs and sealed together with our butyl rubber tapes.
