Drainage PVC (4") Under Driveway

Which four windows?

I always use sand around pipes to prevent rock induced cracks. It also helps the next person by giving them a sand layer warning on a pipe.

All the best,

Peter

Both pictures I attached are the same set of four windows just shown from different angles/perspectives.

Digging the trench.

Looks great, and it is nice to see everyone involved in the project!

I think that if you back fill with sand and gravel, and leave the earth where it is, you will have a nice berm to direct surface water away from the building.

All the best,

I got 15 tons of 57 stone delivered today for that.

The rule of thumb out here is 1' of dirt over a culvert and you can drive anything over it. Culverts however are typically corrugated and double wall, but with you being 18" down, you should be fine for most vehicles. (not concrete trucks though)

Towed this to fill this because the shop is not done fixing my tractor radiator.

Got 15 tons of 57 stone to go in over the pipe.

However about 15’ of trench caved in the rain/ monsoon last night so lots of hand shoveling vs the excavator work.

Success we’ve had two big rainstorms and zero water has come into the garage except a minor amount at the 10’ entrance door (like a quart or less).

Thanks for wrapping up the thread.
