Preparing unit floors at Crusader Park and Warminster Business Park
A grinder works by spinning diamond tipped heads across the floor, shaving the surface down a fraction at a time. On a warehouse or light industrial slab, that removes whatever stops a new finish bonding or lying flat: trowel marks, ridges, lips where one concrete bay meets the next, the weak laitance skin on a screed, painted walkway lines and the thin coatings or old adhesive a previous occupier left behind.
When a unit near the junction of the A36 and A350 changes hands, the incoming business usually wants a new finish, whether that is a resin system from a specialist, vinyl in the office or a fresh levelling layer. Each of those depends on a clean, open surface. We grind it, vacuum it and hand it over ready, so the next trade can start on time.
Grinding has a limit worth knowing before you book. It shaves off high spots, but it cannot bring a floor into level when the whole thing falls or sags across a wide area, because far more would have to come off than the slab can spare. Take too much from a screed and it can end up thinner than its minimum depth. In that case we grind the peaks and then bring the low areas up with compound, as set out on our floor levelling for Warminster page.
For very large areas or thick coatings, shot blasting or scarifying may be quicker, and both sit within our floor preparation work. Resin and polished concrete are outside what we lay, but the slab can be left ready for whoever does.
Grinding extensions, garages and lifted floors in Warminster
Homes produce smaller, fiddlier grinding jobs. A rear extension on a post-war semi is a typical one: the new slab rarely finishes at exactly the height of the old, and a lip often runs along the line of the former back wall. Grinding that lip down, then levelling across the join, lets one covering run through without a bump.
Garages are another. An old garage floor may carry oil stains, paint or a worn coating, and a conversion needs it taken back to clean concrete before a membrane or screed goes on. Our build-up for a converted garage floor explains the build-up that follows.
Then there are floors exposed when carpet or vinyl comes up, still patched with black bitumen adhesive or hard glue. Some of it can be covered, but adhesive that is soft or flaking has to come off before anything new is laid.
Dust is the hazard on every one of these jobs. Silica is present in concrete, screed and tiles, and grinding them without control releases fine dust that is harmful to breathe. We grind only with extraction connected, seal off doorways and protect the rooms next door. If the slab below is cracked or breaking up, it may need concrete floor repair before grinding is worthwhile.
