The yard is collapsing!
This was a very interesting StainStopper installation. A freshly drilled borehole we were asked to fit a StainStopper to prove interesting. Clearing out the soil around the top of the bore casing and we found a massive cavity. It seems there was a cavity around the screen and a large one at that. The client is going to fill the cavity with sand and gravel and prevent any further erosion.
