In 2009 the introduction of continuous ground gas monitoring ushered in a new era of ground gas risk assessment and mitigation. This innovative technology provided timely and accurate data that transformed the way we approach ground gas contamination.
Since then, the availability of continuous monitoring devices and service providers has evolved; companies have come and gone and new instruments have been developed. However, GGS has been a consistent fixture.
In 2006 GGS’s founder, Simon Talbot, collaborated with the University of Manchester on the research project that resulted in the development of the GasClam, the world’s first in-borehole continuous ground gas monitoring device.
Then in 2009, GGS was established and became the first commercial adopter of the GasClam technology. One of GGS’ first contracts was to carry out a ground gas risk assessment to unlock a local authority stop notice on a housing development. After two weeks of continuous monitoring, GGS was able to convince the planning authority to remove the stop notice. The alternative would have been up to 6 to 10 weeks of conventional periodic monitoring.
The value of continuous ground gas monitoring is that it provides high quality data that captures the full variability of a gas regime and the environmental drivers that affect it. It is no longer adequate to accept the uncertainty associated with weekly monitoring rounds and recommendations to add gas protection ‘just in case’. This is approach is costly to developers, wasteful of resources and encourages poor workmanship.
Continuous monitoring has moved from being a niche research tool to a recognised best practice technique sought after by regulators and top-tier consultants alike. The steady growth in demand for continuous monitoring has led to technology improvements and a better understanding of ground gas behaviour. As a result, the technique is more widely available and consultants can now hire continuous monitoring equipment from a range of service providers.
However, GGS remains the market leader, setting the industry standard for a comprehensive and quality assured continuous ground gas monitoring and risk assessment service.
The GGS approach has always been to provide clients with a responsive service that fits their needs; a service based on:
GGS has the largest fleet of continuous ground gas monitoring devices in the UK, including its flagship instrument, the Gas Sentinel. In order to meet the growing demand GGS has increased its fleet of continuous ground gas monitoring devices in 2023 by 25%.
The following pages include news articles, videos, guidance notes and white papers on a range of ground gas related topics which we hope you will find of interest. Please browse through but if you can’t find something on your particular issue of interest, we’d be very pleased to hear from you so we can put that right.
