Installation
Lay the DURABASE DD 80++ membrane with the mesh
fabric facing down loose onto the structural waterproong.
The desired surface construction can be laid onto the mesh
material without further preparatory work.
Please refer to the installation instructions at www.dural.com

Application areas
Accumulation of water
As a result of faults in the sealing gradient, such as increases
in the overlapping area or unevenness, water can accumulate
below tiled surfaces.
Frost and heat
When ceramic ooring is laid in outdoor areas, such as
balconies or terraces, tiled surfaces are exposed to high
thermal loads, which can lead to long-term damage in the
surface structure.
Cracks in the ooring structure
Cracks cause high levels of moisture penetration and eventu-
ally even detachment of the tiles, cavities, eforescence and
fracturing of the joint structure.
Properties
DURABASE DD 80++ is an extremely robust, closed poly-
propylene membrane which is extremely dimensionally
stable and has a dimpled structure with a special mesh fabric
laminated onto the upper side. The dimpled side with the
mesh fabric which supports the tiled structure works as
a drain with exceptional drainage capacity. The conical
dimples and their varying heights facilitate adequate drainage,
even at high volumes. The material is resistant to ageing and
rottingand any residue can be disposed of in the normal
household waste. DURABASE DD 80++ allows for an
extremely exible choice of ooring or surface construction,
thereby offering a high degree of adaptability to the respective
building.
