Grinding back Desborough extension and garage floors
Grinding works by spinning diamond heads across the floor so they shave the top of the concrete or screed away in thin layers. It is a precise way to take a surface down where it stands proud, and to strip off whatever is stuck to it.
Three situations suit it in a house. The first is the join between a new extension slab and the original floor. Even when levels were set carefully, a lip or ridge often runs along the line where the two meet, and grinding takes it down so a single floor can run through.
The second is the garage. A slab that has had years of oil, paint or a cheap floor coating needs taking back to clean concrete before it can be screeded or levelled as part of a conversion, and our guide to garage floor screed shows where grinding fits in that order. The third is the floor found under old carpet or vinyl: black bitumen glue, hardened tile adhesive or patches of paint that will stop any new layer bonding.
Grinding also removes trowel marks, and the laitance on a new screed when it has to be opened up for primer.
What it cannot do is level a floor. A room that slopes or dips gently across its whole width stays sloping however long the machine runs. The answer there is to grind only the high spots, then bring the rest up with compound, a thin latex coat or, for bigger falls, a new screed. Grinding too deep into a screed also leaves it thinner than its minimum depth, so we measure before we start.
Dust control in lived-in Desborough homes
Concrete, screed and old tiles all contain silica. Grinding them creates respirable crystalline silica dust, fine enough to get deep into the lungs and to settle across every room in a house. For that reason our team grinds only with dust extraction connected to the machine.
In an occupied Desborough house that matters as much as the finish. Before we start, we seal doorways into the rest of the home with sheeting, protect the stairs and hall along the route in, and keep the work area closed until it has been cleaned down. Pets and children stay well away from the room on the day.
Grinding is at its most useful on small and medium areas. For a whole floor under a thick coating, shot blasting or scarifying can be quicker, and our floor preparation service covers those methods.
Our machines and diamonds are not for sale or hire, and resin or polished concrete finishes are left to other trades. Grinding here is preparation for the next layer, whether that is our compound or screed, new flooring, or a resin system laid by another trade. If the concrete itself is cracked or breaking up rather than just dirty or uneven, concrete floor repair comes first.
