A cavity drain system is often referred to by Structural Waterproofing Designers as a means of waterproofing protection for underground structures.
According to BS8102:2009 there are three types of protection. Type C protection is known as drained protection and is most commonly formed using a Cavity Drain Membrane.
Table 1 of BS8102:2009 tells us that Cavity Drain systems are suitable for use in any underground structure regardless of the level of risk Ie: The height of the water table in relation to the basement slab.
A Cavity Drain system is made up of a cuspated membrane applied to the walls and floor with a channel at the wall/floor junction. The membrane allows any water ingress to filter down to the slab and find its way to the perimeter channel. The channel directs the water to a sump pump which is situated below the slab. The sump pump chamber will then remove the water ingress to the ground level drains.
The wall membrane is typically an 8mm stud which means an 8mm cavity is formed and the floor membrane typically uses a 8mm/20mm stud. The reason for this difference is that there is potential for a higher volume of water to collect on the horizontal plane than the vertical and so it is good practice to create a larger cavity to accommodate higher volumes.
The cavity drain systems are great for internal waterproofing of existing basements. If an existing basement space is being converted into new accommodation, it may not be possible to install or replace a protective barrier on the outside or the structure and so the Type C cavity drain system is an obvious choice to ensure the environment is completely dry.
The cavity drain membranes are versatile and flexible membranes and easy to install to brickwork, blockwork or concrete walls however great care and skill is required to ensure the cavity drain system is installed as a sealed system to ensure moisture, damp and smells do not penetrate into the basement.
The floor membrane has a compressive strength of 150kN/M2 and can receive a screed directly on top of it and to provide finished floor levels and conceal the waterproofing membrane. Often the vertical wall membrane is concealed using a block or studwork wall built up in front of it to conceal the waterproofing. It is important that the system is maintained at least every six months. Openings must be left in the concealing wall to ensure it is possible to access the flushing points and maintain the channel.
When the engineer attends to maintain the channel, they should also check the sump pump to ensure everything is working order. The sump should contain at least two pumps, one is raised slightly and acts as a backup pump.
Being below ground, cellars have the potential to be invaded by water that naturally sits underneath the construction – so as part of your basement conversion and structural waterproofing project, you’ll also need to have a sump pump installed.
This prevents underground water from building up and flooding the basement, and also helps to eliminate the water that is redirected by the structural waterproofing system. We’ll advise on the right type of sump pump installation required, and only use the highest standards of products.
All of our cellar waterproofing and sump pump systems meet British Standard 8102:2009, but while they’re the most reliable approach to waterproofing, they need to be maintained to keep them in full working order.
Limescale build up and a lack of cleaning and servicing can lead to sump pump failure, which can be costly and inconvenient to repair while also invalidating your guarantee. We offer competitive maintenance packages along with our structural waterproofing and sump pump installation services.
