DELTA dimpled sheeting can be used for all building projects in areas where water represents a hazard. DELTA-MS 20, with 20 mm high studs and increased drainage capacity, was developed especially for underground construction projects. It is applied economically on horizontal and vertical surfaces as "permanent formwork" between a shotcrete layer or

DELTA*-MS 20 between the ground slab and the carriageway construction catches the water when the water table rises and conducts it to the drainage

subterraneous curtain wall and the
concrete structural wall.
The shotcrete acts as filter and keeps the seepage layer free from ground particles.

This procedure allows:
► deliberately drain away or deflect the water in the construction phase
in order to not obstruct the process of setting, especially in the case of water impermeable concrete
► drain away water at reduced pressure on completed structures, or
► bring the groundwater level around the building to the same level and to maintain a uniform hydrostatic load in front of the sealing layers subjected to water pressure.
