Slab grinding
A slab ground back with a planetary grinder, with a dust extractor connected.
Floor grinding
We grind off high spots, lumps and rough patches so the floor is flatter.
Includes
- High spots
- Protrusions
- Surface unevenness
- Concrete, timber, particleboard and plywood
Grinding takes off high spots, protrusions and surface unevenness, so the next floor goes down on a flatter base.
On concrete, we grind. On timber, particleboard and plywood subfloors, we sand the high joints, raised edges and cupped boards flat. It's the same job on a different base.
The floor is assessed first
Grinding takes off the raised material where the check shows the surface needs it.
High spots
Raised areas and trowel ridges sitting above the rest of the floor.
Protrusions
Lumps of material stuck to or standing out of the surface.
Surface unevenness
A wavy surface with no single high point.
The base underneath
The same service on two kinds of base.
Concrete
High spots, protrusions and unevenness ground back.
Timber, particleboard and plywood
High joints, raised edges and cupped boards sanded flat, ready for the new floor.

Questions
Do you grind timber subfloors too?
Yes. On timber, particleboard and plywood subfloors we sand the high spots, joints and edges flat, ready for the new floor.
Will the floor need anything else after grinding?
Sometimes. If there are low spots as well, they get filled. We'll tell you once we've checked the floor.
Often next
Services that often go with this one.
- Low spot correctionWe find the low points in the floor and fill them with the right floor-prep material.
- Subfloor preparationWe fix unevenness, height differences and surface defects so the subfloor is ready for the new floor.
- Specialist workWe prepare over an existing tile or timber floor so new floorboards can go straight over it, and make small cuts in the concrete slab.
