COVERAGE
-The protective ground cover must consist of well-graded soil, sand or crushed gravel (avoid sharpstones or stones with a diameter of more than 2.5 cm).-The protective covering must be distributed using low-load machinery, keeping the covering materialconstantly between the covering and the wheels. -It is important that machinery or other heavy vehicles do not pass over VOLGRIP EP until it has been covered with at least 30 cm of protective material.

DEATAIL
When in contact with water, or just simply in contact with the ground humidity, the natural Sodium Bentonite contained in VOLGRIP EP turns into a waterproof gel through hydration and expands up to 16 times its initial dry volume while remaining waterproof tank to the self-containment implemented by outdoor non-woven textile.In the case of concrete structures, the special VOLGRIP EP needle-punching allows perfect self- containment in such expansion once the casting is carried out (which is very important to obtain high waterproofing.
In fact, the fibres of the non-woven textile (on the external side) protrude purposely from the textile (onthe internal side) and during the casting, the fibres are embedded into the concrete, thereby resulting in excellent mechanical adhesion of all the product layers to the structure (not simple superficial adhesion). Otherwise, in the case of compacted soil for protection, the soil itself will perform the confinement function. The laying surfaces may be damp/wet and must not have any large protuberances or cavities or continuous water flows that could jeopardise the independent sealing of the overlaps. The sheets can be folded and cut in any direction
