Dimpled sheet DELTA^®-MS

Tried and tested dimpled sheet made of HDPE with a high level of compressive strength for the use as an overfill protection, as a blinding layer and as a seepage layer in two-shell constructions (e.g. shoring).

Advantages

Very good resistance
DELTA^®-MS is resistant to chemical and microbiological pollution. Thanks to its resistance to rotting, it offers a material durability in the installed state of a minimum of 25 years. In addition, the sheet is safe for drinking water.
Regular load distribution
With approx. 1800 knobs per square meter and the special knobbed structure, when using the product DELTA^®-MS, there is a favourable pressure distribution and a low point load on the insulation of the perimeter.
Optimised laying
Because of the flat edge on one side, overlaps can be made in an easy way. The diagonal knob structure additionally enables a straight kinking enabling the sheet to rest on the ground without any gaps.
The perfect alternative to the conventional blinding layer made of lean concrete
In comparison with the conventional blinding layers made of lean concrete, the use of the product DELTA^®-MS has the advantage that approx. 5 cm less excavation is required, and the concrete base can be created immediately after the laying of the sheet. Furthermore, the DELTA^®-MS prevents the cement paste from seeping away by protecting the sole from rising damp.
Controlled water drainage when securing excavations through shoring and in case of tunnel building
DELTA^®-MS enables the efficient installation of a seepage layer with various construction types and in the tunnel construction. In this manner, the water occurring during and after the construction work is (temporarily) drained away in a pressure-relieved way.

Application

The product DELTA^®-MS can be used as filling protection on perimeter insulation up to 10 m installation depth and on base plaster, as a blinding layer under concrete floors and as a seepage layer in various construction types and/or in the tunnel constructions.
