Cavity Drain Systems are generally used in basement waterproofing or cellar waterproofing. These services provided by Sussex Damp Experts include cavity drainage membrane, tanking, and external systems. Our highly qualified surveying team can provide you with a wide selection of practical waterproofing ideas and solutions for both new construction and existing basements.

Common Types Of Damp And Its Causes

Rising Damp

Rising damp is a prevalent type of moisture that affects building walls. Moisture from the ground rises through the walls as a result of capillary action. This means that groundwater is drawn up through microscopic channels in the bricks like a series of straws. This water contains salts, which move up the wall as well.

Penetrating Damp

Penetrating Damp, often known as “rain penetration,” results from excessive water invading a home through an external wall. This can happen via walls, roofs, windows, or door surrounds at any property level and is frequently caused by roof tile flaws, broken pointing, blocked weep holes, or faulty seals.

Condensation

When warm air collides with cold surfaces or has too much humidity in your home, condensation happens. This is especially prevalent throughout the winter when your central heating system kicks on during the chilly morning and evening hours.

What’s The Purpose Of A Cavity Drain System?

A cavity drain system is a waterproofing system that consists of a cuspated membrane that is applied to the walls and floor and a channel at the wall/floor junction. Any water that gets through the membrane filters down to the slab and into the perimeter channel. The water is directed via the track to a sump pump beneath the slab.

How Is A Cavity Drain Membrane Installed?

Installing a cavity drain membrane, it’s a meticulous process that involves different skills and techniques. It should be done by professionals and specialised workers.

Generically it can be described in a list of processes:

  • Determine which wall or floor will be worked on;
  • Remove the skirting board with care;
  • Carefully remove the plaster and replace it with stone, brick, or blockwork;
  • Drill holes and inject DPC cream over the external ground level;
  • Apply a coat of primer-sealer to the wall;
  • Carefully attach the membrane to the wall.

Sussex Damp Experts provides a complete design and installation service for basement structural waterproofing following British Standard BS8102, defined as “the protection of structures against groundwater.”

We employ polyurethane plastic sheets with dimples formed into them for cavity drain membrane systems. These are mechanically attached to the walls to create a hollow between the substrate and the interior wall plaster finish, allowing any ingressing water to be collected and drained away from the property; if necessary, sump and pump systems can be installed in the floor structure.

To boost the UV value of the wall structure, insulation-backed plasterboard can be used over the cavity drain membrane system if necessary. The system was created by Sussex Damp Experts’ experienced surveyors and adheres to Property Care Association criteria. Sussex Damp Experts’ standard guarantees apply to these systems.

Advantages Of Cavity Drainage Systems In Waterproofing

Whatever kind of waterproofing is used to retrofit a basement, it must be capable of withstanding groundwater pressure, and the product must have a British Board of Agreement (BBA) or similar independent technical certification.

The waterproofing design meets British Standard 8102:2009 ‘Code of Practice for Protection of Below Ground Structures Against Water from the Ground’ and is easy to maintain in the future.

Once the structure is ready for the Type C system to be installed, a cavity drain membrane system is installed, extending to the vaulted spaces and recess walkways.

We can also install sophisticated monitoring systems that detect high water levels within pump sump chambers and monitor pump station performance, running regular health checks on the pump stations in a non-invasive way to monitor and troubleshoot electrical/mechanical failures before they occur drainage system is supported.

The End Of Wet And Musty Underground Areas

Basement conversions are a fantastic method to gain much-needed space that can be used for various purposes, such as building an extra bedroom, a gym, or a children’s playroom — the choices are unlimited, and the days of the dark, damp cellar are long gone.

Converting wet basements and other below-ground spaces into dry rooms can be a cost-effective and enjoyable way to expand a home or make better use of existing space.

Sussex Damp Experts specialises in waterproofing methods for upgrading existing basement rooms, waterproofing new structures, and converting damp, disused spaces below ground into dry living rooms.
