Basement Waterproofing in Belleville IL

Location: Belleville, IL

Job Type: Basement Waterproofing

Overview:

The home was built in the 1920’s. The residence is two stories with a wood frame construction. The basement foundation was constructed mostly of unformed concrete and brick, with the floor being dirt and gravel. Extensive remodeling had been ongoing in the upper levels of this residence throughout Mr. Knight’s tenure.

Problem:

Mr. Knight reached a point of his remodeling when he realized his crumbling foundation walls would require replacement, and the water leakage in his basement would need to be addressed before he could continue. Mr. Knight was referred to Helitech after receiving bids from 6 other foundation repair contractors. Helitech prepared an engineered solution to replace/repair portions of the basement walls and correct this problem in an appropriate manner.

Solution:

Helitech installed temporary structural supports to carry the load during construction, removed the existing foundation walls and footing, and designed/constructed a new concrete footing. Helitech then replaced the east and west walls with poured concrete and concrete masonry blocks and installed treated sill plates and termite barriers on top of the new foundation walls. Helitech lowered portions of the basement floor approximately 18 inches, thus allowing the basement to be fully functional as additional living space.

Helitech applied a Hydraway Ultrashield waterproof coating to the exterior foundation walls and installed a Hydraway waterproofing system around the interior foundation footing. Helitech then set the floor to grade with gravel and replaced the existing dirt floor with a poured concrete.
