With most jobs, we excavate the whole house, remove the asphalt, concrete, whatever needs to be removed to dig a 4 foot trench from the wall around the house.
Once we excavate it, we take any cracks we find, clean the wall, and chisel 2 to 3 inches on either side of the crack. We then repair it with hydraulic cement and bonding agent. The bonding agent is important because it makes the old concrete adhere to the new. Then we tar the whole thing and wrap it with hydro guard which is a membrane that prevents hydrostatic pressure. We then use a drain tile which is a perforated PCV pipe with a sock on it. The purpose of the sock is to filter out all the silt. We cover the exit pipe with drainage stone about 6 to 8 inches thick. The drain tile that surrounds the house is attached to the sewer line.
Once the job is complete, we do a complete clean up, put the decks back, where ever there was concrete or walkways, we’ll replace it with crushed stone. We recommend at least a year’s wait for the earth to settle around the foundation before the client does any landscaping or paving.
We also fix and repair fieldstone foundation and masonry stone foundation.
