Warning
Moisturein a basement can createmold and mildew, as well as ruin flooring and wall materials.
And this backfill can settle more than the surrounding undisturbed soil.
Over time, the backfill compresses, creating a slope (grade) that angles downward toward the foundation.

This can involve trucking in substantial amounts of soil to reverse the direction of the slope.
This can be a difficult problem to correct.
Driveway slabs sometimes develop sunken areas near roof gutter downspouts.

Each rainstorm will dump water from both roofs onto the driveway.
Roof downspouts can add a literal flood of water to areas prone to drainage problems.
A 1,500-square-foot roof will shed around 940 gallons of water in a 1-inch rainstorm.

Downspouts often dump water right at the base of the foundation.
But the vast amounts of water flowing off a roof can easily overwhelm such systems.
Also, check that the gutters are clean and flowing properly.

For major floods, a water mitigation company can remove water and dry out a basement.
If there are more than 2 inches of standing water, buy or rent a submersible sump pump.
Remove any wet carpet and insulation and damaged drywall immediately.
Dry out furniture, walls, and any items kept in your basement.
Salvaged items need to be thoroughly cleaned and sanitized.
