In the case of strip or pier foundations factory-made floor elements are used instead of a concrete foundation slab. The floor beams of the elements may me made out of solid wood, solid wood compound beams connected with nail-plates, I-beams, laminated timber or Kerto-wood – the specific choice depends on the width of the span. The floor elements are insulated with glass wool or with some other insulating material and covered from below with moistureproof plywood or some other type of board depending on local conditions and requirements as well as with a wind barrier. From the top the floor elements are covered with moistureproof chipboard or OSB board to which all the necessary layers may be installed on site depending on the purpose of the room, from parquet flooring to ceramic tiles.
The accompanying image shows a principal solution for a floor element.
