What diamond grinding fixes on Sudbury floors
A floor grinder cuts the surface away in very thin layers with rotating diamond heads. It takes material off, so it suits faults that stand up or sit on top: a bump, a raised join between two concrete bays, trowel ripples, a weak surface skin of laitance, glue left by an old covering, painted floors and worn thin coatings.
Several of those turn up in ordinary Sudbury refits. Pull up a tired vinyl or carpet in a kitchen and the old glue is often still there, patchy and too uneven for a new floor to bond to. Homes built between 2000 and 2014 make up 14% of the town's housing, and one of those on its first change of flooring may still have the original adhesive under the covering. Grinding takes it back to clean concrete or screed.
Extensions are the other usual case. A new slab or screed rarely finishes at exactly the height of the floor in the old house, and even a small ridge along the join will show through LVT or tiles. Grinding the high side down removes that lip. Garages are similar: a slab used for years may carry paint or a worn coating that must come off before insulation and screed go on, and our garage floor screed guide covers the build-up that follows.
Once the surface is clean, the floor can take levelling compound, a new screed, a resin system applied by others or the new flooring itself. Shop and office refits follow the same steps.
Dust, depth and limits on Sudbury floors
Concrete, screed and tiles all contain silica. Cutting them throws up respirable crystalline silica dust, which is harmful to breathe, so we only grind with dust extraction connected to the machine. In a lived-in Sudbury house the room is sealed from the rest of the home, doorways are masked, and adjoining floors and furniture are covered before the first pass.
Grinding has limits worth knowing before you book it. It flattens local high spots, but it cannot correct a floor that slopes from one wall to another or sags across the middle of a room. Grinding that level would take off far too much. The usual answer is to grind the peaks and then level with compound, or lay a new screed if the error is large, and our floor levelling service in Sudbury picks up from there.
Depth matters as well. A screed has a minimum thickness, about 65mm for a floating sand and cement floor in a house, and grinding too much away can leave it thinner than that.
Our team does the grinding itself; we have no machines or diamond tooling for sale or hire, and resin or polished concrete finishes are left to specialists. Where a coating is thick or the floor is very large, shot blasting or scarifying may suit better, as our floor preparation page explains.
