OMEGA BASETOP Screed Sheeting

Is a high vapour-impermeable moisture and radon barrier. The special multi-layer sheeting consists of a quality corrosion-resistant aluminium layer with fleece reinforcement on both sides. The sheeting was specially developed as damp-proofing for use on floor slabs with ground contact as a protection against ascending moisture in accordance or on intermediate floors, as vapour barrier above rooms which are subject to a high degree of stress in terms of construction physics. The adhesive backing on both sides permits a quick, clean and tight seam during handling.

INFO

The sheeting is laid loosely with approx. 10 cm overlap on even ground surfaces which are free from sharp edges and soiling.
If required the membrane can be bonded with the substrate over the entire surface using UNI XL Primer Spray (contact bonding method).
The longitudinal seams become permanently sealed and watertight by simply pulling off the backing strips followed immediately by pressing down the adhesive joint.
End joints and seams must have an overlap of min. 10 cm, using OMEGA PLASTO Adhesive Tape.
Membrane connections at penetration points, rising structural elements and damp-proof courses must be made using OMEGA PLASTO Tape Adhesive Tape. The overlap should be min. 10 cm. If required the substrate may be pre-treated using UNI Primer Spray.
