Concrete and flatwork covers the flat, poured surfaces around a property: driveways, patios, footpaths, garage bases, sheds bases and screeded floors. It's a different skill set from wall-building or repointing. The contractor needs to get sub-base preparation, falls (drainage slope), reinforcement, mix design and curing right, because a concrete slab is very hard to fix once it's down and cracking, pooling water or breaking up at the edges within a year or two usually traces back to a shortcut at one of those stages.
Bristol's mix of clay soil in areas like Bedminster and Brislington and older, uneven ground on hillier streets around Totterdown or St George makes sub-base work especially important here. A contractor who skips proper excavation and hardcore compaction on clay ground is setting up future cracking, whatever the concrete finish looks like on day one.
What to check before you hire
- Sub-base depth and drainage: ask what depth of hardcore they're planning and where the water will run to.
- Reinforcement: mesh or fibre reinforcement for driveways and anything taking vehicle weight.
- Movement joints: proper joints stop random cracking as the slab expands and contracts.
- Finish type: brushed, tamped, exposed aggregate or power-floated, agreed and priced upfront.
- Written quote: area, depth, materials and clean-up included, not a vague day rate.
