Whatever the material, backfilling a basement foundation puts a momentary stress on the walls. Let the concrete cure for at least a week before backfilling (28 days is best). Place and compact the backfill carefully in partial lifts—don’t dump it all in at once.Click to see full answer. Similarly, how long does it take for backfill to settle?If you have time, fill it to within 1 foot of full, wet it down until water stands on top, then finish by rounding it off to shed rain. Let it dry and settle for several months and you have a foundation that is virtually incompressible.Beside above, does rain Help dirt settle? Re: Time For Earth To Settle It comes down to how much rain we get. A couple of good thunderstorms will settle backfill in a matter of a week or two, but if it’s dry or frozen, it basically won’t settle on it’s own. Also, how do I backfill around my house? When it comes to backfilling, free-draining backfill that’s free of any construction debris will relieve hydrostatic pressure on the foundation walls, minimizing the burden on your foundation waterproofing. This backfill should be properly compacted with a cap layer that will shed bulk water away from the foundation.Can you build on filled land? #1: Don’t Build on Fill: If you cannot dig down far enough to rest the footings on solid and undisturbed ground, then you run the risk of having the ground settle after you home is built. This can cause severe wall cracks or structural failures.
