Concrete Floor Grinding in Rochester

Our own team carries out concrete floor grinding in Rochester as preparation, using diamond heads to remove high spots, ridges between bays, laitance, old adhesive and floor paint. Medway City Estate, on the Frindsbury Peninsula in Strood, holds about two million sq ft of warehouses, trade units and offices, and refitting one of them usually means taking the old slab surface back first. In houses, grinding deals with extension joins, garage floors and glue left after carpet comes up.

Unit refits at Medway City Estate and Neptune Business Park

A unit at Lakeside Park, Neptune Business Park or elsewhere on Medway City Estate seldom hands over a clean slab. Previous tenants leave floor paint, line marking, carpet tile glue and thin sealers, and none of those give a new compound or adhesive anything reliable to hold.

Diamond grinding strips them. The heads spin against the floor and cut away the top in thin layers, taking the coating and a skin of concrete with it. On the way they flatten the local defects that show up under a straightedge: lips where adjoining bays were cast at slightly different heights, trowel ridges, raised patches over old service runs.

Dust is the part that needs most care in a business setting. Concrete and screed contain silica, and grinding them makes fine dust that can be breathed deep into the lungs. We grind only with extraction attached to the machine and screen off offices, stock and neighbouring areas.

The result is a clean, open surface ready for the next layer: levelling compound, screed, a resin system by another contractor, or the flooring. We do not lay resin or polished concrete, and we do not sell or hire grinders. For very large floors or thick coatings, shot blasting or scarifying may be quicker, and both sit under our floor preparation service. Shop units at Cory's Wharf and the rest of the non-residential space at Rochester Riverside face the same question when their floors are fitted out.

Extension joins and garage slabs in Rochester houses

Semi-detached houses make up 33% of Rochester homes, and the domestic jobs that need grinding are found in houses of every kind.

Where an extension slab has been cast against an older one, the two rarely finish at quite the same height. A lip of a few millimetres is better ground away than buried under a thick build-up of compound.

Garage floors are another. Before a garage becomes a room, oil, paint and old sealer have to come off, or the screed laid over them will not bond. Grinding gets back to sound concrete ready for the membrane, insulation and screed that follow.

Then there are floors under lifted carpet or vinyl, where hard glue and stains stop anything new from sticking.

Grinding has a clear limit. It removes high points but cannot fix a floor that falls or dips across a room, and taking off too much can leave a screed below its minimum depth. Then the answer is to grind the highs and level, explained on the Rochester floor levelling page. Where the concrete is broken rather than just rough, concrete floor repair comes first. We grind floors in Gillingham too.

FAQs

Concrete Floor Grinding in Rochester: your questions

Can grinding remove floor paint from a garage?

Yes. Floor paint and thin coatings are among the things diamond grinding handles well, along with oil staining that has not soaked deep into the slab. The aim is clean, open concrete that a primer, compound or new screed can bond to. Thick coatings over a big area may be quicker to shot blast, which we would advise on after seeing the floor.

How much of the surface does grinding take off?

As little as the job needs. The diamonds cut in thin passes, so we can stop once a coating or high spot has gone. That control matters on screed, because grinding too deep can leave it thinner than its minimum depth. On a Rochester floor we check what the layer is and roughly how thick before starting.

Do you polish concrete or lay resin after grinding?

No. Grinding is preparation, and we finish by leaving a clean, sound surface. Polished concrete and resin systems are specialist trades we do not take on, though our ground surface can be handed to a resin contractor. If the next layer is compound, screed or flooring adhesive, we can carry the job on ourselves.
