we have encountered some difficult ground conditions on site lately in the form of running sand (photos attached) so this slowed us down for a week while we de watered the area. This involved drilling to a depth of 5 metres and installing pipes so we could pump all the water out of the ground to enable us to install the drainage. we are currently working on the last of the three concrete chambers and hope to pour the concrete walls next week. I have attached a short video showing the directional drilling (auger bore) works which allows us to install pipework without actually digging.
