Grinding Clarion's new slabs in South Wimbledon and Mitcham
The council's largest ever project is Clarion Housing Group's rebuilding of the High Path estate in South Wimbledon and of Eastfields and Ravensbury in Mitcham. Alongside the new homes it includes commercial and community space. Fresh concrete in new units is rarely ready for a finish straight away. Slabs poured in bays can leave lips where they meet, ridges from the trowel and a weak skin of laitance on top, and any of those can spoil thin flooring or make an adhesive fail.
A grinder deals with all three. Diamond segments on rotating heads shave the surface in thin passes, bringing a lip down until it is flush, flattening ridges and removing the skin to expose firm concrete. Primer then soaks into a surface that is open and clean rather than sealed by dust and laitance.
There is a limit to what the machine can do. It corrects small, local high points, but a unit floor that is out of level across a large area cannot be ground true without cutting far too deep, and on a screed that risks going below the minimum thickness. In that case we grind the high spots and bring the rest up with compound or a fresh screed.
Grinding is also the step before a resin system, which a specialist lays after us; resin and polished concrete are not finishes we lay. For floors that are cracked or broken rather than just rough, see concrete floor repair.
Merton garages, extensions and Wimbledon shop units
In homes, grinding usually follows a lifted floor covering. In Merton, 13% of homes were built between 1973 and 1999, and floors in houses of any age can hold several generations of carpet glue and vinyl adhesive. Taking that off by grinding leaves concrete that a latex smoothing coat or new adhesive can hold to.
Extensions bring the lip problem indoors. Where a kitchen extension on one of the borough's Victorian terraces meets the original floor, a slight step at the join is common, and grinding the high edge lets the two be levelled as one surface; the levelling page for Merton explains that next stage. Garages being converted may have paint, oil and a rough top that need removing before any build-up.
Between tenants, shop units in the town centres of Wimbledon, Mitcham and Morden can need the same treatment: old adhesive and paint ground off, then compound and a new finish.
Every grinder we run is connected to a dust extractor. Concrete, screed and tile contain silica, and grinding them throws up respirable crystalline silica dust, so neighbouring rooms and shops are sealed off before work starts. Our operators bring the machines; we do not supply grinders or diamond tooling to others.
