DELTA®-MS

DELTA®-MS as a sub-base course

DELTA®-MS

DELTA®-MS is a field-proven dimpled sheet consisting of special high-density polyethylene with a high compressive strength of c. 250kN/m². 

Because DELTA®-MS features more than 1,800 dimples per square metre, pressure distribution is favourable and point loads on perimeter insulation are low in practice. The sheet is non-polluting for drinking water, is rot-proof in soil, and offers at least 25 years material resistance when installed.

DELTA®-MS in vertical applications

DELTA®-MS reliably separates foundation walls from moist soil. The dimpled sheet offers comprehensive protection for compression-resistant waterproofing and/or perimeter insulation.

The sheet forms an extremely effective protection layer on the substrate. The requisite drainage is provided either by highly permeable soil or by a seepage layer of mineral material (e.g. gravel sand belonging to the B32 grading curve) that is at least 50cm thick and is guided up the wall. If necessary, DELTA®-MS may be used as a vapour-pressure equalising layer.

Flat overlap edges permit fitting seams precisely. Moreover, the diagonal arrangement of the dimples permits straight folding.

DELTA®-MS System for tunnel construction

DELTA®-MS is the rational and dependable solution for coping with water in tunnel construction projects of every kind. The spaces between the dimples pointing outward, i.e. towards the living rock or a stabilising shotcrete filtration layer, merge into a continuous channel system through which the water emerging from the rock can drain away. The subsequent waterproofing layer may be attached directly to the dimpled sheet if required, using rational fastening methods. Artesian water pressing outward will drain off unpressurised through the dimpled sheet so that the waterproofing will be protected from hydrostatic pressure from the start. Where water-impermeable concrete is used, DELTA®-MS serves as permanent shuttering. Seepage water will be kept away during the setting phase.

DELTA®-MS as a sub-base course

A substitute sub-base course for floor slabs

A reinforced floor slab requires a foundation on which the spacers for the reinforcement mesh may be placed. Using lean concrete for a sub-base course requires digging a 5cm deeper pit. Added to that, there will be high working costs, additional equipment costs, and waiting time. Particularly where relatively large areas are involved, this means higher costs and delayed progress. Where DELTA®-MS is used as a sub-base course, crucial advantages are installed off the roll: minimum installation time, high compressive strength, no equipment costs, no additional excavation, no waiting time, additional protection of the slab from rising damp, and no leaching out of the cement paste. DELTA®-MS resists acids, bases, oils, and solvents. The sheet is tough and stiff enough to be walked on and traversed by wheelbarrows. It safely supports the lower strip-shaped spacers for the reinforcement mesh. A DELTA®-MS sub-base course is the ideal alternative to a traditional sub-base course of lean concrete.
