I hired a contractor to waterproof one side of my house. He got rid of some of the backfill and reassured me he would be putting gravel in it to replace what's removed. He did not. Now every time it rains the ground along that side of my house sinks. It is an area that extends 45 feet long by abt 2.5 feet wide. What is the best way to fix this?
I have some interlock stones sitting in my yard. Can I fill it up with screening and lay the interlock stones on top?
Thanks in advance for your advice.
You will need to excavate pathway. Install 5/6 inches of compacted base grave to required slope . Install 2 inches of screeded sand and install paving on top with a polymeric sand to finish. Pathway should slope minimum 2 inches
Thanks for the inquiry the best way to refill that would be put gravel in gravel provides an excellent drainage for water the ground is going to keep syncing until it stops ground was Disturbed don't finish the top until next year let the dirt and gravel settle then top up accordingly can I ask where you're located
Thanks for you replies and great advice. I will wait until next year. It's just that because we walk on that side of the house there is so much mud whenever it rains. The mud is tracked everywhere.
I am located in Brampton, Ontario.
The contactor did not compact the bacfill at all and he disposed of a lot of the soil so I don'thave any left to fill the sink holes. Where can I order gravel and backfill in bulk to keep filling up this hole everytime it sinks?
Hate to disagree with the other respondents; don't know the full story of the landscaping plan for the side of the house (plantings, sidewalk, etc.) or how bad it is, however here are some pointers:
best thing when backfilling is to have a clay cap with a minimum 10% slope away from the home. Foundations need to project minimum 6" above grade (8" if wood siding) by Code.
The idea of the clay cap is to keep the basement a little less damp + reduce the burden on the weeping tile (assuming you have).
If a walkway is planned good idea to have some 'road crush' or other suitable granular beneath. If you're planning to pour concrete the settlement will likely continue for many years.
If you're going for a shrub bed beside the house good idea to have 8-12" of black dirt over the clay cap; if sod then a few inches is adequate.
The cost of material is mostly in the trucking so try to find something as close to site as possible; if you want clay or other fill perhaps look for construction activity nearby.
