The importance of soil levels

When you’re installing a new lawn it’s important to considering the soil levels before a single roll of turf is delivered. If you have a naturally sloping block then the soil levels are pretty much determined for you but if your block is level then you have a little work to do. The aim with a level block is to actually create a slight slope for surface drainage. This is particularly important if you have a clay soil which is prone to drainage issues. On some sites that slope naturally towards a building or on level sites, surface drains or underground drainage systems may be necessary; if this is the case contact a drainage specialist before you install your new lawn.

 

When levelling your soil start levelling around the outer edges where the finished height is often already determined. You can use a steel rake or a topsoil spreader to achieve the desired result. When the outer edges are complete use string lines to get all the levels in line. Set a taught string line across the area around 50mm about the soil and use that as a reference point, levelling the soil accordingly. Use this process over different sections of your yard until it’s all done. As you go remove any debris, rocks, small tree roots and break up any large clumps of soil.

 

From here, you can use a water-filled roller to systematically firm up the soil and expose any depressions that require attention. Water-filled rollers can be hired from all of the usual places. Adjust any imperfections after rolling. What you’re aiming for is a soil that is firm under foot – your footprint should sink in just a bit, but not too far. If the soil is too soft your turf, once installed, will sink resulting in an uneven surface that is not only unsightly but poses a trip hazard.
