Lightweight Intensive Roof Garden Soil

Lightweight soil is a blend of screened sandy loam (40%), coir (20%), PAS100 Green Compost (20%) and LECA 4-10mm (20%).

The loam complies with BS 3882 (2007) and is screened to 10mm.

The high proportion of LECA, light expanded clay aggregate, reduces density and enhances drainage characteristics.

The material is free flowing, safe, easy to handle and is available in loose bulk loads, bulk bags or 25kg bags (32 litre)

This specialist topsoil is suitable for use where bulk density and free drainage characteristics are critical, such as in roof gardens or in planters on roofs where point loading is limited.

Lightweight Soil is not recommended for ericaceous (lime hating) plants

CPA, Thank you for our lightweight top soil which we are very happy with. Our only gripe is that we had no idea when it was to be delivered, except we hoped it would appear on the date we specified. It would have been nice to have the delivery date confirmed by the transporters, and even an approximate time of day, but we were glad to get it when it did come and we did stay in all day to receive it. Thank you. Tony
