At what stage can I put the foundations in and what type of ground floor finishes can I have?
If you are deciding to go along the timber frame route you should wait to receive the timber frame company’s soleplate layout drawing before progressing with your foundations. The soleplate layout will have all panel and diagonal dimensions required to set out the foundations including which wall panels will be load bearing / non load bearing. To ensure a successful project it is imperative that the ground worker works to the timber frame company’s soleplate layout and constructs the base within the allowed tolerances. To achieve this a recognised / recommended ground working company should always be used.
FLOATING GROUND FLOOR – Ground floor finish laid when the structure is watertight which generally consists of Vapour barrier / 60mm Polystyrene and 18mm V313 Moisture resistant floor decking (can be laid on top of a concrete base or concrete beam and block floor). (This floor is suitable if the majority of the ground floor is to be carpeted or similar)
POWER FLOAT FLOOR – A finished concrete floor that is layed using a power float machine before the timber frame arrives. The concrete is screeded off flat and allowed to reach initial set before work starts. This method avoids having to lay a screed or a floating floor at a later date. (This floor is suitable for finishes such as tiling or carpeting)
CONCRETE SCREED – An in situ flooring of cement mortar laid to an accurate flat surface by screeding. Screeds are laid on the structural floor (concrete base or concrete beam and block floor) and usually have no reinforcement – in a timber frame situation it would be laid after the structural shell has been erected (generally approx 65mm deep). (This floor is suitable for finishes such as tiling or carpeting)
SUSPENDED TIMBER GROUND FLOOR – Can be supplied by the timber frame manufacturer as pre-cut joists to be constructed by the erection team. The floor would not generally be insulated and decked until the structure is watertight. (This floor is suitable if the majority of the ground floor is to be carpeted or similar)
