The surface area must be waterproofed according to a.b.e.® Construction Chemicals’ specification. This is not a primary waterproofing membrane but is recommended for buried dual layer system applications. The first layer consisting of a 3mm abe® unigum torch followed by an antiriot bituminous membrane Index Defend H. Lay abe.®drain 20 P in place with the dimples facing downwards. Should it be necessary to overlap, then 150mm would be sufficient. Apply super laykold waterproofing tape 100mm wide along the flat part of the product for this purpose. Where required place a geotextile membrane loosely on top of the abe.®drain 20 P before spreading out the soil. This is important as the soil would otherwise fill the dimples and thereby reduce water drainage Spread out the soil according to the instructions of a qualified landscaper.
Do not butt-joint sheets.
Install abe.®drain 20 P as supplied using an overlap of 150mm between the sheets resulting in an overall coverage of 35m2 per roll.
