The foundation of the outer wall of my garage is lower than that of the inner wall. Water seeps when it rains. Is it useful to fill the outer wall? Please fill in the property.

The low seepage of foundation is caused by the infiltration of water in backfill soil, and backfill soil is useless. It's best to waterproof the exterior wall with high quality. If the backfill can be dug, permeable crystalline waterproof coating and polymer waterproof coiled material should be used for waterproofing. Be careful when handling, and ask professional waterproof personnel to do it. If it is inconvenient to dig backfill soil, or it is impossible to dig backfill soil, the back water surface can also be treated with seepage control, and UD high-strength special long-term seepage control material can be used for spraying treatment.
