Overview

An essential part of completing the remediation of brownfield sites is the topsoil and subsoil used to cap the site.  Delivered in association with Boughton Loam (formerly British Sugar TOPSOIL) and Tim O’Hare Associates, this webinar brings together leading experts to discuss the key requirements in:

  • the selection and sampling of appropriate soil sources
  • the assessment of site-won and imported soils
  • soil compaction – problems, causes, avoidance and repair
  • the design, placement and verification of the clean capping layer.

What you will learn

This is key to successfully clearing NHBC and Local Authority conditions, and knowing how to get it right the first time can be important when it comes to having funds released by lenders.

You will leave the webinar with greater knowledge of the various sources of topsoil, pitfalls, sampling and testing and the Local Authority/NHBC requirements.
