DampSafe 603 (M19)
3 mm loose laid floor membrane.
Use with John Newton Waterproofing Tapes.
A high quality flooring membrane suitable for use above new and existing floors. The 3 mm studs allow for pressure equalizing of dampness within the floor below, allowing for dissipation at room perimeter and subsequent drying of the floor.
The studs also give slight compression to footfall making the floor very responsive and comfortable, and therefore suitable for use as the floor membrane for performance sports floors.
DampSafe 603 uncouples the floor finish from the substrate. The membrane also bridges small cracks allowing for quick floor installation above uneven substrates.
The membrane is guaranteed against deterioration for 30 years, and has a life expectancy of at least 50 years.
DampSafe 603 can be finished over with screed, 18 mm or 22 mm tongue and groove chipboard or particle board. Laminate and timber flooring should be installed over a layer of 18 mm or 22 mm tongue and groove chipboard.
