New build lawn groundwork
From construction subgrade to lawn-ready finish.
The best time to establish correct lawn levels is while machinery access is still available and before fences, landscaping and other finishing work restrict the site.
Supply and spread screened topsoil
Place clean screened topsoil to the required depth while maintaining finished heights around slabs, paths, patios and drainage points.
Leave it ready for the lawn finish
Accurately trim and grade the surface for ready lawn, hydroseed or conventional grass seed.

Estimating new-build topsoil
Area multiplied by soil depth gives the volume.
For a new build, the required quantity also depends on the existing subgrade and the finished heights beside slabs, paving and drainage.
100 m² lawn at 100 mm depthRequires approximately 10 m³ of topsoil before allowing for settlement or uneven subgrade.

New-build lawn questions
Plan the groundwork before access disappears.
When should new-build lawn preparation happen?
Ideally after the main construction earthworks and permanent hard-surface levels are known, but before fencing and landscaping restrict machinery access.
Can you supply and spread the topsoil?
Yes. We can prepare the construction subgrade, supply screened topsoil, spread it and complete the final grading required for the selected lawn finish.
How deep should the topsoil be?
The suitable depth depends on the existing subgrade, required finished heights and intended lawn result. Site plans, photos and measurements help establish the correct volume.
Can you match paths, patios and driveway levels?
Yes. These fixed heights are important reference points. The lawn should finish below hard surfaces while maintaining suitable falls away from the house.
