Why waterproofing at the edges matters more than the middle
The area most likely to fail in a kitchen is not the open floor but the perimeter around the sink base unit, dishwasher and washing machine, where water leaks are most likely and least visible. Sheet vinyl with heat-welded seams, or LVT with a fully bonded edge and silicone detail at wet junctions, keeps moisture out of the subfloor rather than just off the top surface.
- Sheet vinyl seam-welded near sinks and appliance runs reduces the number of joints where water can track through
- Click LVT is not recommended directly under freestanding washing machines or dishwashers without a glued-down section
- Silicone (not just grout or trim) at the wall-to-floor junction behind taps stops water tracking into skirting
- A damp-proof membrane is worth confirming on ground floor solid concrete kitchens, especially older properties
