Hi, I’ve been asked to update these CAD drawings to show the floor build-up. Is this something you can do, and what would the cost be? The proposed floor construction is as follows: - Tile finish with adhesive and grout - Decoupling mat - Levelling compound (up to 20mm) - 75mm screed - Vapour barrier - 125mm PIR insulation - Structural concrete subfloor Based on this build-up, there is approximately 200–230mm of non-structural material above the concrete slab. As such, all fixings will need to bypass these layers and achieve adequate embedment into the structural concrete. We propose the following fixing approach: - M12 threaded rods - Chemical (resin) anchors - Minimum 100mm embedment into the concrete slab - Total fixing depth approximately 320–350mm Please let me know if you need any additional information. Thanks, Matthew
