Interior System

Everdry Wisconsin | Interior System

Interior System: Inside drains may be used to waterproof from the inside of the basement. Typically, this involves opening the floor around the perimeter of the basement, digging a trench, and installing pipe and gravel around the footer. The contractor also installs ‘weep-holes’—small, one-half- to three-quarter-inch holes in each block cavity—to release any water that may be trapped. The holes are covered with a plastic molding or styrene panel before the floor is re-concreted.

Cons:

Highest risk solution since it brings surface water inside, then pumps it outside.

Unprotected outside walls susceptible to more cracking and leaking.

May lead to undermining of footer.

Warranty covers floor only.

Does not address humidity which causes mold growth.
