Grinding old floors and extension joins in Ewell
When carpet or vinyl comes up in an older Ewell house, the concrete beneath is rarely clean. Black adhesive, rubber backing stuck to the slab, paint splashes and patches of tile glue all sit between the new floor and a proper bond. Diamond grinding takes them off. Rotating heads set with industrial diamonds cut the top of the slab away in thin passes, opening up the surface without breaking into the floor below.
The same machine deals with ridges. Where a rear extension has been added, its slab or screed rarely finishes in a perfect line with the old floor, and a lip of a few millimetres at the join will show through LVT or crack a tile. Grinding the high side down, then feathering a compound across, brings the two together.
Garages give a third reason to grind. A painted or sealed garage floor has to be taken back to bare concrete before a bonded screed or new flooring can grip it. Thin coatings come off by grinding; thick coatings over a large area are usually quicker with shot blasting or scarifying.
Newer screeds can need a pass too. In Ewell, 8% of homes were built between 2000 and 2014, and a cement screed of that age may still carry a weak surface skin or trowel marks that adhesives dislike. A light grind removes them.
How much comes off is measured, not guessed. Every screed has a minimum depth, and grinding away too much can leave it thinner than it should be, so we take only what the job needs.
Dust control in occupied Ewell homes
Concrete, screed and old tiles all contain silica. Grinding them releases respirable crystalline silica, a fine dust that hangs in the air, drifts through a house and is harmful to breathe. We therefore grind only with dust extraction: the shroud around the diamond head is connected to an industrial vacuum that draws dust away at the point of cutting.
Where the family is living in the house during a refit, containment goes further. Doors to the rest of the house are sheeted and taped, the work area is closed off, and the floor is vacuumed when grinding ends so no dust is left for the next trade.
Grinding has limits worth knowing before you book. It removes local high spots, but it cannot flatten a floor that slopes or dips across a whole room, because cutting deep enough to do that would weaken the floor. On a floor like that we grind the high points and then pour self levelling compound for Ewell floors or lay a screed.
Once the surface is clean and sound, it is ready for compound, screed, new flooring or a resin coating from a specialist. Resin and polished concrete are specialist finishes we leave to others, and our grinders and diamond tooling are not for sale or hire. If the next layer is a thin skim, see latex screed in Ewell.
