Darby and his crew did some more waterproofing on my home at the rear after having done similar work about 8 years ago on the side.
I have to say the soil is horrible - clay, rocks, bricks, rubber tubing and all sorts of 30+ year old debris. Work on the job was made more difficult by finding some huge old concrete footing from days gone by leaving them only 18" of room in which to work for about 1/3 of the width of the foundation wall. And a power conduit emerging 30" down at one side that connects to the garage, so they had to dig around that.
Nevertheless they dug and worked on time and on budget even finishing up a bit early on the final of three days.
This is back breaking work and at the same time requires a lot of attention to detail - after excavation they applied a coating of parging concrete, then on top of that a rubber/tar compound and then on top of that heavy plastic sheeting to create a waterproof sandwich. Plus in this case they had to install a new window well and the drainage tubing and gravel for that.
I was satisfied 8 years ago for the first time Mud Monkeys worked under somewhat less horrible conditions, and I am satisfied again.
This might be once in a lifetime work but when it has to be done, I would not call anyone other than Darby and his team to do it.
