Optional gas membrane (supplied by other) If required, a gas membrane can be easily incorporated as TETRiS produces a smooth, level surface for the membrane to be draped over and built into the course work accordingly.

Underfloor heating systems (supplied by other) An underfloor heating system can easily be integrated into the floor prior to applying the structural concrete floor finish.

Option 2Cover the TETRiS blocks with a D49 steel mesh, cable-tie the underfloor heating pipes to the mesh at the desired centres and cover with the structural concrete. Install the heating manifold at a later stage.

Lightweight partition walls not exceeding2 0.75kNm can be built anywhere off the

finished floor.

Option 1Secure the underfloor heating pipes to the TETRiS blocks with ‘U’ anchors at the desired centres and cover with the structural concrete topping. Install the heating manifold at a later stage.

Lightweight non-load bearing concrete block(1)partition walls built parallel to the beams

MUST be constructed within a 75mm (each side on the centre line of the beam) zone directly above the floor beam(s).
