The Complete Job
From Ground Preparation to Finished Concrete
A dependable base starts well before the concrete arrives. Northern Grit Concrete is not a ready-mix delivery service — the work covers preparing the ground and installing the finished base or slab, so the whole job is dealt with in one go.
There is no point rushing what sits underneath. Where agreed, that includes taking away spoil and old material once the work is done.

Why Preparation Matters
A Proper Base Starts Below the Surface
There is no single thickness or specification that suits every job. What is needed varies with the structure type, manufacturer instructions, load, ground conditions, drainage and intended use.
- Ground conditions
- Clay, made-up ground, soft spots and tree roots all change how the area is dug out and prepared.
- Excavation depth
- Depth depends on what is coming off the top and what the finished level needs to be.
- Levels
- Levels are set against the house, garden and any existing hard surfaces before shuttering goes in.
- Drainage
- Water needs somewhere to go. Falls and surrounding levels are considered as part of the job.
- Sub-base
- Crushed stone laid to a suitable thickness gives the slab something firm to sit on.
- Compaction
- Laid in layers and compacted — loose stone under a slab causes problems later.
- Shuttering
- Timber formwork holds the concrete to the right size, line and thickness.
- Reinforcement
- Mesh or bar is used where the structure, load or design calls for it.
- Concrete depth
- Thickness is decided by the load and the requirements for that particular structure.
- Curing
- Concrete gains strength over time. We explain how long to leave it before building on.

Straightforward Approach
No Fuss. Just a Properly Planned Job.
Most problems with concrete work come from unclear expectations rather than the concrete itself. So the aim is simple: talk it through, agree what is being done, then get on with it.
What preparation is needed
Before anything is booked in, you will know what has to come out and what goes back in.
What the quote includes
Set out clearly, so there is no guessing about what is covered and what is not.
Access requirements
Where materials come in, where spoil goes out and anything that needs moving first.
Waste removal
Whether excavated material and old surfaces are taken away as part of the job.
Timing
A realistic idea of when the work can be carried out, rather than a promise we cannot keep.
Curing
How long the concrete needs before the structure can be installed on it.
Supplier confirmations
Anything that needs checking against your building supplier's base specification.
Prices are not fixed in advance and availability varies with the weather and current work. Every quote follows a proper look at the job.
