Grading and fill:
The area under the front porch collects water from the driveway due to the dirt under the porch being lower than the driveway. The GC suggests that we do the following:
1) fill the low spots with dirt and grade away from foundation
2) add 6mil black plastic to keep moisture from penetrating
3) cover plastic with float stone
$1800 in materials ($1000 12-13yd float stone, $300 dirt, $500 plastic)
$4400 in labor which includes shoveling, wheelbarrows etc. that’s steep but it’s a lot of material to move
I’m looking for validation that it is wise to grade away from foundation and give water a place to go at this appreciable but ultimately nominal cost.
-GC suggests it would prevent future frost heave of footings. I agree with that.
-GC suggests that moisture sitting under joists isn’t great long term. I also tend to agree there
-GC suggests this is standard practice. We do have truly nonexistent grading and no stone under there currently. I believe that it’s standard practice
-GC suggests this (the stone mainly) will help with critters. Haven’t had an issue so far but makes sense
So, my prompt to the GJ commenters and thinkers here is, is there value in another $6k of site work, or is this busy work? Aside from the area that pools water, is this worth doing under a covered porch? I have them moving forward but can be convinced otherwise. Always happy to pay for work that has functional value even if I can’t see it
The pooling under deck. Definitely needs to be improved
And the area that will have no grading. Why do it above and not down here? Makes me question if I should either do both or neither:
