Specifications
To provide under-screed drainage and a capillary break preventing moisture and salts below the sheet from migrating to the surface.
Solution
VersiDrain 6P sheets were installed over structural slab prior to application of the topping screed and installation of the surface decorative pavers. The sheets positioned between structural slab and topping screed prevents water and salts in the screed from migrating upward via capillary action minimising efflorescence on the pavers above.
