Hi-Newbie here. Last spring I had an inground pool installed. The repeated driving of large trucks, backhoes, cement trucks etc. next to the house caused a crack in a foundation wall from a window corner almost to the floor. It is at an angle. There is a little efflorescence near the bottom of the crack. I would say it is a little wider than hairline, but nothing gaping. It has been very wet here. The ground never dried last summer and now there is snow melt. We plan on fixing a dip in the ground where there is standing water caused again by the trucks compacting the ground. There is a 9 inch gap between the foundation wall and the concrete patio. We are planning to put in a drain there tied into a downspout. Doe this sound like a good plan and is the crack someting to really worry about? I have read that the cause of the crack is as important as the fix but seeing as it was the truck traffic and nothing else I'm hoping it won't be a huge problem. We never had water there before this. BTW-pool builder has disclaimer in contract absolving itself of any responsibility for cracked foundations. Thanks so much for any information.
