Expanded Free Ground-Gas Webinar Programme

Read More

GGS had arranged to run a full series of ‘A-Z of Ground-Gas’ training events throughout 2020. This is the tenth year we would have run these in collaboration with PAGeotechnical. However, due to Covid-19 social-distancing, these events have now been postponed.

As an alternative, GGS has put together the following programme of FREE 1 hour technical webinars to be held at 10:30 BST. Find the registration links on our training page or below:

11th May – Introduction to continuous ground-gas monitoring

Sign up here

2nd June – Best practice in continuous ground-gas monitoring

Sign up here

23rd June – Geology 101 for ground-gas contamination

Sign up here

Further webinars are scheduled on the following dates at 10:30 BST and registration links will be published soon.

14th July – Continuous monitoring and the Source-Pathway-Receptor pollutant linkage

4th August – The Lines of Evidence approach to ground-gas risk assessment

8th September – Radon – source, hazards, monitoring and remediation

29th September  – Mine gas hazards, monitoring and risk assessment

If the current lockdown is relaxed this programme may be revised and the A-Z training events will be re-established if this can be done safely.

Reduce ground gas risks and successfully complete developments

Read More

As technology advances, environmental monitoring data is increasing in volume and expanding in range. The potential for these advances to refine the accuracy and speed of ground gas risk assessments is significant. Nonetheless, choosing the right technology, technique and team to perform these often complex on-site risk assessments is still a crucial consideration.

Radon: the hazard and managing the risk

Read More

Radon gas is a natural hazard that we can’t see, feel or smell.  Consequently, most people are unaware of it and the risks often don’t get the attention they deserve.

‘The A – Z of Ground-Gas’: What people say about it and why you should join

Read More

After eight years of delivering training on best practice in ground-gas monitoring, we’re very proud and assured that our two day courses meet the needs of our varied delegates. However, we don’t expect you to take our word for it. Take our customers open and honest accounts of their experiences instead. Read our ground gas training review and we’ll see you in 2018.

How do I find out if my building is in a radon-affected area?

Where radon occurs

Radon is a naturally-occurring radioactive gas produced by uranium decaying underground. It seeps into buildings through floors, walls in contact with soil, and through water or gas supplies. When inhaled, radon atoms decaying in our lungs can cause damage to cells and cause lung cancer.

It’s associated with geological types like granite and shale, and the probability of finding high radon levels has been mapped for the UK in the ‘Indicative Radon Atlas.’ Although detailed, it only gives an indication – you have to test to be sure.

Save time and protect your development with 3rd party verification

Read More

Everyone agrees that Britain needs new homes, and quickly. Targets at both local and national levels increasingly focus on the redevelopment of brownfield sites; with the dream of transforming derelict space into thriving communities. Of course, the simple message sold to voters doesn’t encompass the difficulty of clearing and converting a former industrial unit into flats, or building on old landfill. Ground-gas can be a danger in any development but, as the focus switches to brownfield, developers are increasingly being expected to officially validate that effective ground-gas measures are ensuring the safety of future site users.
