Hogmoor Field Dynamic Probe Investigation

We are hiring a dynamic probing rig to investigate the features at Hogmore Field following on from our radar investigation in June 2016.
This rig will percussively drive a sacrificial steel cone into the ground using a mechanised drop hammer. Blow counts are recorded per 100mm of penetration into the ground and the blow count profile can be used to indicate the nature of the ground conditions and soil profile present. We would expect to complete say 5 or 6 probes to 10m depth in the day. The probes can be taken deeper if wanted – around 60m total probing can be done in a day. We are hoping to use an iPad with an app that allows GPS positioning of the probes and the outline of the feature we choose to investigate. We should be able to relate back to the previous investigation works we carried out.

If you'd like to join us please contact us via this booking link to get access details. We plan to gain access to the site to set up the equipment between 08:30 and 09:00, but you could come along at any time to see what we are doing.

About us

Chalk MicrographThe Berkshire Geoconservation Group is a volunteer group which works with local authorities, landowners and the general public to safeguard our special landscape for future generations and to promote understanding of its geology and geodiversity.

We designate sites of significance within the county so that these can be conserved and enhanced where appropriate. We also produce a Local Geodiversity Action Plan which identifies actions to be taken over a five year period. Blackwater Gravels This aims to guide the conservation and interpretation of the geological features of Berkshire.

If you are interested in any aspect of geoconservation please consider joining BGG. Even if you do nothing else with the group, by simply becoming a member you will be making a big difference. Membership is free and all members receive news and information about our activities.

Over the year we have a regular programme of walks to areas of geological interest and anyone is most welcome to join us. If you would like to suggest a walk of interest then please do so. We are always happy to give talks to local groups about the geology of the area.

Contact us if you would like more information.
