Basement & Cellar Waterproofing
Basement conversions offer a great way to get much needed space that can work for all different situations, creating an extra bedroom, a gym or children’s playroom – the possibilities are endless and the days of the dark, damp cellar are firmly confined to history.
Converting damp basements and other spaces below ground level into dry rooms can be a cost effective and highly rewarding way of extending a home or utilising space within an existing property.
Sussex Damp Proofing specialise in the provision of waterproofing systems that are employed to upgrade existing basement rooms, waterproof new buildings or convert damp, unused spaces below ground into dry habitable rooms.
Structural waterproofing below ground is a highly specialised operation and must be undertaken by contractors and designers who have the requisite levels of skill, understanding and experience. Failures resulting from inadequate specifications or poor workmanship can be very costly. Sussex Damp Proofing specialise in structural waterproofing and are able to work with the client to design a suitable waterproofing solution.
Waterproofing in existing underground structures is usually undertaken by applying waterproof membranes to the inside walls and floors or by using drained cavity technology. Waterproofing techniques are defined in BS8102, the British Standard for “Protection of structures against water from the ground”.
Structural Waterproofing Systems
The two types of waterproofing system commonly used in existing structures are. Adhered waterproof membranes or “type A” waterproofing systems (as defined in BS8102) are commonly multi coat renders, cement based coatings, bituminous paints or epoxy coatings. This form of waterproofing provides an unbroken barrier to water. These systems are applied to clean walls and floors and are usually protected and held in place by floor screeds, renders, plasters or other “loading coats”.
Cavity drainage systems or “type C” waterproofing usually utilise pre-formed high density drainage membranes, channels and sumps. These are designed so as to direct any water entering the structure back out in a controlled and managed way. Typically cavity drain membranes are installed to the walls and floors these direct water into drainage channels. The channels then allow water to be directed to sumps or drains so that it can be removed safely from the building. Cavity drain membranes provide an alternative to conventional cementitious tanking systems, which work by holding the water back. Cavity drain membranes work on the principle of allowing water to continue to penetrate the structure but control it in the air gap and divert it to a suitable drainage point. They do not allow pressure to build up against the internal construction and the air gap behind the membrane allows the structure to breathe and to some extent to dry out. The membranes are lose laid on floors and fixed to walls using special plugs and sealing materials, with little or no preparation required to the substrate. Once the membrane has been fitted, wall surfaces can be dry lined or plastered directly and floors can be screeded or a floating dry board system installed.

Sussex Damp Proofing supplies products and systems designed for cellar waterproofing and other general waterproofing works in new build and existing properties. Key products for waterproofing include Isola Platon cavity drain membranes, which are designed for use in all cellar or basement waterproofing projects to control the ingress of damp or running water. A complete range of Isola Platon polyethylene studded membranes is available which can be specified according to the application and which work on the principle of allowing the damp or running water to travel behind the membrane to a controlled drainage system. Benefits of cavity drain membranes over other damp proofing methods include the minimal disturbance and preparation required to the existing substrate and their toleration of structural movements.
Sussex Damp Proofing specialise in structural waterproofing and basement conversions and are able to consider the nature of the building and the clients design requirements to ensure that the correct method of waterproofing is selected and executed to enable the highest standard of basement conversions.
