ASL has extensive experience in contaminated land risk assessment on a wide range of contaminated land sites including petrol filling stations, former gas works, scrap yards, engineering works, power stations, ordnance and battery manufacturing plants and railway land. We continually conduct research into new investigation and remediation techniques and current legislation to ensure that the advice we provide is the best available.

ASL offers a full range of geotechnical investigation and assessment services including the determination of design parameters for the following:

• Gas Protection
ASL site investigation works include monitoring for the presence of ground gases that may pose a risk to human health within the completed development. Where such risks are identified, generally in the form of elevated concentrations of methane or carbon dioxide, gas protection measures are required. ASL provides recommendations for suitable gas protection measures based on the monitoring results. This can include specification of gas resistant membranes and design of subfloor venting.
