Topsoil Production


PAS100 compost and sand is delivered to our production site.


Materials are mixed together to our specified blend which is compliant to BS3882:2015.


Each batch will undergo rigorous testing to ensure its consistency and compliancy.


Once the topsoil blend has been approved, it is loaded onto the appropriate delivery vehicle in either bulk bags (1m3) or loose (tonne).


The order is sent out for delivery via a specialist haulier.

Topsoil Calculation

To calculate the cubic meterage of your site, multiply the width x length x depth.

Using the answer from the above formula, multiply the volume by the soil bulk density.
