per the backfilling with peastone/gravel, its not really (the gravel) that ‘protects’ the drain tile, its much bigger purpose is gravel isn’t going to ‘consume’ lol, aka saturate as does expansive clay soil, silt, so the more gravel against a foundation wall, versus clay-silt, the less lateral-soil-pressure against the wall, water isn’t going to sit-in, the gravel and make the gravel SWELL, no, so it would be less pressure acting upon the wall on upcoming rains. I thought i saw ‘some’ sand, couldn’t really get a good gander of most of the soil that was dug out
did they put in the black perforated drain tile along FOOTING OR clay or pvc, just wondering
N i see they piled some soil near-along the open trench, apparently it didn’t cause any cave in at your place but doing that, could, was risky imo.
so you know, we’ve done quite a few BOWED IN wall jobs over the years and many of them we ‘saved’ the existing wall, i’d guess around 1/2 were a little or a lot worse than your wall (what i could see in photos)… the homeowners were either short on cash or just opted to get it, HAND dug out, waterproofed and then backfilled with all gravel, no leaks and only 2 that i am aware of had… a little more movement, not much, but did move, didn’t pop OPEN cracks… one cannot take ALL of the EXT pressure/weight off a wall i guess is what im trying to spit out.
One of the last walls SOMEONE else rebuilt, if i remember correctly they did the back wall and about 8–10 feet of side wall, i think the cost was $12,000…it DID re-leak and owner found us and had us redo the waterproofing, DC, NY etc are more expensive but still seems a bit high
