I have had several estimates hovering the $1000 mark for those companies that use long probes to inject sealant into the ground around the foundation to seal cracks.
I have a tri-level townhouse with the sublevel being finished with drywall on the walls and carpet on the floor. During heaving rainstorms I get water seepage from the same area of the wall where a fireplace kit is. Most of the fireplace components are out, but their remains a sheet metal shield that would be difficult and messy to remove, thus an inside inspection and repair of the crack is out of the question.
Directly opposite of the leaking wall on the outside is a deck, of which the boards run directly to the foundation.
Access to the foundation or ground underneath would mean removing quite a few of the deck boards.
I hope I've accurately described how difficult this is.
1) I'm wondering what is the best soil/sand/gravel combination to have under a deck so close to the house to weep away the rain?
2) Is there equipment available for rent (Home Depot says no) that would allow a home owner to inject the "sealants" used by contractors to fix a foundation crack?
3) Any idea of costs involved?
If someone wants a better understanding of my situation, I can email pix.
Thanks for any/all help-suggestions.
