发帖数: 1175 | 1 First look for places that need to drain water away from your foundation.
Fixing drainage (including gutters) is cheaper and more permanent than doing
from inside.
If you can not fix drainage, then consider draining from inside. However,
most crawlspace "experts" try to sell the drain from inside, which is more
expensive and unnecessary --- don't call them first unless this is the only
way.
Call the drainage people as your first bet. |

Sure, just make sure the soil/mulch is at least 12" away from the siding.
No need, as long as the water can flow away to a lower place.
If you can't discharge all the water off your property, find a spot with
good drainage and as far as possible from the house. Guide all the run-off
to this spot and maybe add a dry well to improve the drainage. For aesthetic
purpose, build a rain garden there. |
