Preparing unit floors on Hersham's trading estates
Industrial and trade unit floors collect layers. One tenant paints the floor, the next coats it, a third marks out lines for racking. When a new occupier takes a unit on an estate such as Hersham Trading Estate or Riverdene Industrial Estate, any layers left behind usually need to come off before anything new can bond.
Diamond grinding does that job. The machine's rotating heads carry diamond segments that cut the surface away in thin layers, taking paint, thin coatings, adhesive and the weak laitance on top of the concrete with them. The same pass knocks down ridges and lips where bays of a slab were cast at slightly different heights, a common cause of trip edges and of bumps under new finishes.
What follows depends on the use. A unit that will take a resin coating gets a ground, clean, open surface for the resin contractor, because resin and polished concrete are not work we take on. An office or trade counter area might be ground and then levelled with compound for carpet tiles or vinyl. A worn area that needs a hard wearing topping might be ground and then given a bonded screed.
Thick coatings or very large open floors can be quicker with shot blasting or scarifying. Cracked, spalled or broken concrete is a repair job first, covered by our concrete floor repair work. We say which method suits once the floor has been looked at.
Garages and extension joins across Walton-on-Thames
Garage conversions are a typical project on Walton's inter-war and post-war semis, and the old garage slab is often painted, oil stained or rough. Paint and stains stop a membrane, primer or levelling compound from bonding, so they are ground away to leave clean concrete before the floor is built up with insulation and screed.
Extension floors raise a different issue. Where a new slab meets the original house there is often a lip along the join. Grinding takes the high edge down so the new and old floors meet without a ridge under tiles or boards. Detached houses are 22% of Walton's homes, and across a wide open plan ground floor even a small lip is easy to spot under a long run of boards.
Grinding has a limit. It takes off high spots, but it does not make a sloping floor level. If a floor falls across the room or dips in the middle, cutting the whole area down to its lowest point would remove too much, and on a screed could go below its minimum depth. The sensible plan is to grind only the high spots and then lay compound or a screed, which our Walton levelling page explains.
Inside a lived-in home, dust is the main worry. Grinding concrete makes respirable crystalline silica dust, so we only grind with extraction attached and seal off doorways. Across the river, see concrete grinding in Sunbury-on-Thames.
