The wedi Fundo drain-substructure element eliminates any possibility of failure resulting from poor positioning of the drain body. It guarantees reliable support and accurate aligning of the drain and thus time consuming building and filling with mortar and screed is not required.

This element is made of XPS foam. It is not reinforced and is not coated. It is especially recommended for use in suspended timber floors and can be shortened continuously by up to 20 mm.
