Solving Your Water Problems
Removing the water pressure against a foundation is how professionals usually waterproof a home against seepage. There are a few basic types of drainage methods that accomplish this task, and they often produce excellent results. To deal with rising groundwater, a drainage system installation may require digging through the concrete slab of a foundation next to the walls, installing the system, and then connecting the drains to a sump pump. To defeat surface water seepage, a waterproofer may install a wall and footing drainage system that collects and routes water away from the foundation. Since in both cases the water pressure against the basement or crawl space is removed, these repairs are typically a long-lasting solution.
The injection method is used to seal cracks in poured concrete foundation walls. Small holes are drilled into the crack, and an epoxy material is injected. This material seeps through the full width of the crack and bonds the two sections of concrete back together, prohibiting water from entering through the crack. The repair is complete once the entire crack is sealed. The process is fairly noninvasive, but the injection method is not a suitable fix for all types of water-related problems, nor will it work for all types of foundation walls; homeowners should consult with waterproofing professionals before deciding whether or not the injection method is the best option for addressing seepage.
