Made Ground – dark brown, slightly gravelly, slightly
clayey SAND. Gravel is fine to coarse flint, brick and clay
roofing tile with occasional slate, charcoal and asbestos
fragments
The coarser made ground was generally encountered
along the line of the access road, farm yard and under
former building footprints. Elsewhere surface deposits of
asbestos cement board/drainage pipe were identified
over highly organic topsoil.

Development Requirements
Presentation by JPC Environmental Services Ltd & Elvanite Recycling Ltd Remediation of Asbestos Impacted Soils
Opportunity to retain suitable material on site
Fill areas such as
Building footprint
Carpark
Design Constraints
Engineering requirement for a ground bearing slab, ruled out the placement of material beneath building footprint– Type 1 fill required.
Drainage requirement for soakaway restricted the fill area of the carpark for fibre impacted fines.

Site Works –
Delivering the strategy on site
Adopt common strategy to
satisfy both reuse and off site
disposal demands
Site walkover and hand pick all
visible surface deposits
Strip site in a defined sequence to
minimise cross contamination
Moving from low risk to high risk

Localised caches / concentrated hotspots were identified, isolated to start, then treated at source as far as possible.
Excavated soils only screened once the bulk of the asbestos removed.

The stock piles were placed within their
own risk areas to further reduce the
risk of cross contamination
The clean/low risk soils stripped from
the green/paddock area, were retained
on site as topsoil, subject to validation
sampling
The medium and high risk material was
screened under controlled conditions,
hand picked to remove asbestos
