Intensive Topsoil
Lightweight Topsoil
Specified for general planting on roofs and podiums and a vital part of SuDS
Description
Intensive roof gardens are identical to any standardised "floor" garden and require maintenance, irrigation and management throughout the year. Our Intensive Roof Soil is purely an evolution of the standard BS3882:2015 multipurpose topsoil, but with an added element to bring down the bulk density. A clean, free-draining (sandy) loam with good levels of NP and K is blended with Lightweight Expanded Clay Aggregate to create a relatively free draining substrate that will sustain a variety of planting schemes. Ideally your As Received Density won't exceed 1200kg/m³ whilst the Field Capacity Density is ideally <1500kg/m³.
