They arrived on time, and set the work site out and commenced drilling holes through the foundation on the last or last but one the drilling the copper water supply pipe was hit which was not your operatives fault it was installed beneath the foundation. This distracted me from the activities that Uretek was doing, I noted the laser level was set up and indicators (6no) were mounted on the wall and injection took place. I do not know how much product was injected in. I hope this stabilizing process has worked time will tell, but your operatives did a good job thanks
