发帖数: 206 | 1 Hi, is there any problem if I put plastic film under the new top soil
applied to improve the grading close to the wall? Would that help prevent the water seeping through and pressure the foundation?
Thanks very much! | m***y

new technology.
Just a few of things off the top of my head
1. You need to glue 1' of the plastic sheeting to the basement wall. We used
to use roof cement, but not sure what's the best adhesive now that there
are so many new glues in the town.
2. Back fill with gravels, not top soil. Most likely, you can't find a good
plant for these spots, so forget about top soil. Another benefit of gravels
is, they provide better drainage than soil.
3. Nowadays, it's recommended to use landscape fabric wherever gravels meet
soil, so that the soil can't migrate into gravels and fill up the cavity.
4. If possible, you still need a drain tile to lead the run-off away from
your basement. A few feet of plastic sheeting helps, but if you can lead the
water 20' away, it's better. |
