Rigid uPVC VISTAGARD (Hatari) for underground cable and pipe protection.
This newly developed uPVC tiles are more practical, easier to handle and come
in signal red or sulphur yellow.
The many advantages over the conventional concrete tiles make this product
far much better for all applications and this is the main reason why, throughout
the developed world, the uPVC tile is making a big impact in covering underground
pipes and cables.
Effectiveness of concrete cable tiles is gradually reduced with time for the
following reasons :
The steel reinforcement bars rust because concrete is porous. This process is particularly fast in moist / wet ground conditions. The concrete itself is a rigid
brittle material which can crack or flake when exposed to mechanical stress.
Such stresses can occur after installation when the back-
oads are applied downwards from ground level. Concrete brittleness also leads
to the deterioration of the tiles surface making any embossed lettering more
and more difficult to notice and read.
In the case of rigid uPVC cable tiles, a life span of at least 50 years is offered.
Proof of this is the use of rigid PVC pipes for water transportation all over the
world, uPVC pipe systems installed in Europe 50 years ago are still functioning
trouble free; indicating that rigid uPVC is highly resistant to ground conditions
and retains its properties over long periods of time.
