Topscape Subsoils are tested in line with BS8601:2013
Subsoils make up a key component of soil profiles providing storage and moisture while transmitting rainfall to deeper layers and watercourses, enabling deeper rooting of trees, grasses, and plants.
Subsoils can control the waterlogging of surface layers and help vegetation to withstand drought and provide tree anchorage.
Subsoil plays an important role in reducing the amount and speed of surface water runoff, reducing the risk of erosion and flooding; becoming an integral part of sustainable drainage systems.
In the context of soil profile construction, the Subsoil is an important medium for root growth providing reserves of water, plant nutrients, and mechanical anchorage.
Topscape Subsoil (and Topsoil) can form valuable cover systems that break any pollutant linkage and provide an effective barrier between underlying contamination and any surface development.

Why use Subsoil?
Additional info
British Standard Subsoil - In order to offer plants, turf, and other vegetation the best opportunity to grow, the topsoil must comprise of a certified combination of minerals, nutrients, water, organic matter, air, and living organisms. As this mix can be hard to achieve naturally, the British Standard for Subsoil was introduced to ensure landscape architects, contractors, and specifiers have a ready-made point of reference to enable them to supply and spread a safe and tested product.
BS8601:2013 ensures that each certified subsoil mix contains the correct pH level, to determine the correct acid/alkaline balance; the ideal physical composition to help avoid compaction; the right electrical conductivity value; as well as the maximum level of stones or sharps permitted.
Subsoil manufacturers, including Tarmac Topscape solutions range, are also regularly tested in line with BS8601:2013 standards to ensure all products are suitable for the intended end uses. Whilst different geographic areas will each have a unique geological composition – some may contain more sand, limestone or chalk than others – BS-certified subsoil can be used for all general-purpose applications, such as lawns or communal grassed areas across the country.
