Health & Safety / CDM

Minimal exposure to contamination (e.g. asbestos) for workforce and public
Gas dispersal is controlled and diluted with fresh air prior to dispersal.
Reduced risk from less vehicle movements and lower plant requirement.
Shallow excavations, less than 0.65m deep.
Minimal open trench required as the installation progresses.
Small working zone made fully secure at the end of each shift.
Robust, vandal resistant dedicated vent terminations, designed for a school environmental.

Engineering & Environmental

Predominantly a no-dig solution with a minimal generation of excavated material that is generally from the upper inert capping layer.
Contaminated ground remains in place.
Any arisings are used to backfill over the top duct with any surplus arisings regraded to suit original ground levels.
No dewatering requirements.
No impact on site hydrogeology.
No impact on existing foundations.
Replaces the requirement for aggregate venting media
Reduces burden of site traffic on existing roads as the venting composites used are up to 100 times more efficient that gravel venting media.
Uses recycled and recyclable materials.

Financial Benefits

Low mobilisation / start-up costs.
Rapid installation will enhance site programme.
Negates the off-site disposal of contaminated material.
Minimises importation of granular materials.
Low maintenance requirements post installation.
Minimal site disruption of other trades.
Can be installed while other earthwork operations take place, such as ground improvements.

Sustainability

Reduces the environmental impact of your development as it uses recycled and recyclable materials
Reduces impact of quarrying through low reliance on aggregates
Reduces impact of tipping / landfill through no-dig installation method
Requires significantly less lorry movements than alternatives considerably reducing your carbon emissions.
