Part of Triton Systems’ range of cavity drain membranes for use as part of a drained or ‘Type C’ waterproofing system, Platon P8 is designed to be applied to the inside face of basement or below ground walls and floors.
P8 is manufactured from HDPE and is impermeable to water, water vapour and Radon gas.
Its studded profile has a construction height of 7mm and it is pliable enough to be formed around corners and projections without the risk of breaking - even in very low temperatures.
Quick and easy to install, P8 is supplied in 2.07m x 20m rolls and can be cut easily with a knife or scissors.
Its BBA certification satisfies the requirements of third party building warranty providers (NHBC, LABC etc).
Type C waterproofing is defined in BS 8102: 2009 as ‘drained protection’ which is achieved by the incorporation of a drained cavity within the basement structure.
Water is collected in the cavity formed between the external wall/basement floor and the studded cavity drain membrane, and diverted to a suitable drainage point.
The use of cavity drain membranes manages pressure building up against the internal construction, and the remaining air gap created between the studs and the structure allows the structure to breathe and, to some extent, dry out.
Cavity drain membranes are loose laid on floors and fixed to walls using special plugs and sealing materials, with little or no preparation required to the substrate. Once the membranes have been fitted, wall surfaces can be dry lined or plastered directly, and floors can be screeded or a floating dry board system installed.
Triton also supplies the full range of plugs, seals and tapes required for installation of a Type C system as well as pumps, sumps and drainage components.
It’s important to note that the basement wall must provide enough primary resistance to water ingress to ensure the cavity only accepts a controlled amount of water or dampness.
Cavity drain membranes can be used within a standalone Type C system or as part of a combined strategy with other forms of waterproofing depending on site conditions, planned use of the basement or below ground area and risk assessment.
Other Platon cavity drain membranes are also available from Triton Systems including those designed to be plastered or plaster-boarded directly, and for external use to protect the primary liquid applied or self-adhesive waterproofing membrane.
