Solid strip timber flooring can be fixed directly to joists, sheet subfloors of particleboard or plywood over joists, and plywood or battens over concrete slabs. In some locations, direct fixing to the concrete slab is standard. The traditional timber floor is renowned for its strength, durability and character. Throughout their life, solid strip timber floors can be rejuvenated to near-new conditions by sanding and refinishing. It is ideal for new houses or to match existing floors in renovations, and they can be top (face) nailed or secretly fixed in combination with adhesives.
