V-Tec Installation

Installing a V-Tec Floor is a simple three-step process, similar to the laying of the more traditional concrete beam and block system.

  1. The V-Tec beams are laid out.
  2. The blocks are inserted.
  3. The screed is laid.

To ensure benefits and services are sequenced in the correct order, in particular before the concrete screed is poured, the installer must first become familiar with the features listed in the EPS Floorblock.

The V-Tec beams are laid out spanning wall to wall according to site plans. Spacing between the beams will be in accordance with the type of infill blocks specified and the corresponding load span tables. For the standard EPS floor block the spacing is 750mm from beam centre to centre.

The blocks or formers are then simply slotted in position between the beams. They interlock below the beam to provide a smooth ceiling surface and to prevent cold bridging in suspended floors, balconies, terraces and flat roofs.

With the floor blocks in position, in built services are added before laying the concrete. If required, first the timber floor fixing batten should be inserted into the preformed groove. This is followed by the installation of both horizontal and vertical pipe work and/or ducting and finally by any under floor heating coils. All electric cables and wiring should be encased in regulation conduit. For ease of maintenance, ducting of water and other service pipes is advised.

The V-Tec Beam has a pre-camber and generally at all spans up 4.5m there is no need for a forest of supports whilst the concrete pour is underway. When a mid span support is required the props should be left in place until the concrete has reached the required design strength.
