This is an equipment specially designed for manufacturing walls with double layer of concrete and an inner hollow.
This kind of precast panels are widely used for the construction of earth-retaining walls and underground enclosures. This hollow panels are inserted with the protruding reinforcement of the foundations and then they are filled with concrete so that they conform a solid wall. This avoids the need of using formworks.
The mould for double wall allow adjusting the distance between both concrete layer, in order to vary the final wall thickness.
As well as other Moldtech equipment, the mould for double wall can be supplied with heating by finned pipe and with external vibration, pneumatic or electrical.
