If your Caerphilly lawn stays soggy all winter, goes bald in summer and never seems to thicken up, the problem is usually a few inches down. On many new developments the ground is driven over by diggers and dumpers for months, then a thin skin of topsoil is spread over it and turf rolled out on top in time for the keys to change hands.
When we lift a failing new-build lawn, these are the things we most often find:
- Subsoil packed so hard by machinery that roots and water cannot get through it.
- Heavy clay close to the surface, which holds water in winter and cracks in a dry spell.
- Only a shallow layer of topsoil, sometimes less than a spade's depth.
- Buried bits of brick, concrete, plastic and offcuts left from the build.
None of this means the builder did anything unusual; it is simply how a lot of new gardens start life. The fix is to strip the turf, break up the compacted layer, pick out the debris, bring in good topsoil and relay. Where water still sits, a simple drain can help. Our advice piece What Lies Under a New-Build Garden in Caerphilly goes into more detail, and Laying Turf in a New-Build Caerphilly Garden covers the relaying itself.
