Floor Tiles Lifting in Rainham

Floor tiles that lift, rise into a ridge or pop up with a crack, sometimes called tenting, are under pressure from movement they cannot absorb. Tiles and the floor beneath expand and contract with temperature and moisture, and without movement joints around the edges and across large areas, that pressure has nowhere to go but up.

Other causes include adhesive that did not bond properly, a floor underneath that moves or holds damp, and underfloor heating that was switched on to full heat too soon after tiling. It can happen suddenly, often with a loud crack, and lifted tiles can have sharp edges, so keep people off the area. Do not try to glue them back down yourself, because the pressure underneath will simply lift them again.

In Rainham we see it on larger open-plan floors in the newer homes around Beam Park, and on conservatory floors in South Hornchurch where temperatures swing. The fix is to lift the affected tiles, find the cause, and relay with proper movement joints and full adhesive cover.
