Envirotreat was engaged to undertake gasworks remediation (E-Clay Stabilisation) at the former Rectory Lane gasworks site Guisborough.
The first phase of the project involved the emptying, cleaning out and off-site disposal of the underground tar tank.
An E-Clay stabilisation treatment methodology was adopted for the second phase of the works. This stage involved the excavation of tarry impacted materials from around the tar tank and across the site. The stockpiled soils were treated in batches using E-Clay. Representative samples were leach tested and compared to the agreed remediation target criteria.
Validated soils were reused on site to return level to pre-remediation levels.
