Unit floors at St Mary Cray and Lower Sydenham
A unit that changes hands usually keeps its old floor. The previous tenant's floor paint, worn sealer, carpet tile adhesive and patch repairs all sit on the slab, and nothing new bonds reliably to any of them. Grinding cuts through those layers back to sound concrete.
St Mary Cray is the largest area within that corridor, and when a unit there is refurbished, the floor is part of the job. Lower Sydenham's business area on Kangley Bridge Road raises the same question at the start of a fit-out: what is on the slab, and how much of it has to come off?
The method is simple to describe. Spinning heads set with diamonds shave the surface off concrete or screed a little at a time. On a warehouse slab that takes down the ridge where two pour bays meet, the trowel marks left from the original finishing and the raised edges around old patch repairs. Each pass is controlled, which matters, because grinding too far into a screed can leave it thinner than the minimum depth it was designed for. Where the build-up is unknown, we check its depth first.
Very large areas, or thick coatings, can be quicker to strip by shot blasting or scarifying; both sit under our floor preparation service. Once ground, the slab can take compound from our Bromley levelling service or a coating applied by a specialist. Resin and polished concrete are not finishes we lay.
Extension lips, garages and old glue in Bromley homes
In houses, grinding is usually a small, targeted job. Post war homes in Orpington and the Crays suit extension slabs, and where a new slab meets the original floor the two seldom finish dead level. A lip of a few millimetres across the opening will show through LVT. Grinding the high edge down, then skimming, gives the fitter a continuous floor.
Garages are the next case. Years of oil, paint and tyre marks stop a new screed or compound from bonding, so the slab is ground back before a conversion; our garage floor screed guide shows what goes on afterwards. Lifting carpet or vinyl in an older house often reveals black or yellow adhesive, and grinding removes it where scraping cannot.
Grinding has one firm limit. It removes local high spots, but a floor with a fall or a hollow across a whole room will still slope afterwards. There, we grind the high spots and then level or screed the rest.
Dust is the other point to understand. Concrete, screed and tile all hold silica, so cutting them sends up respirable crystalline silica dust. We grind only with extraction connected at the head, and we screen off neighbouring rooms. The grinders and diamond tooling stay with our own crew; they are not for sale or hire.
