Foundation Crack and Rod Hole Sealing
Foundation cracks and rod holes allow for easy paths of storm water migration into basements. Sealing these areas is a budget friendly option that can often resolve a water issue without the need for excavation. With this method, the crack or hole is sealed from the inside. Polyurethane foam is injected into the wall and expands to create a strong bond with the existing concrete. Unlike other methods of repair, the polyurethane foam fills the entire void up to the exterior part of the wall.

Frequently Asked Questions – Basement Waterproofing in Ann Arbor, MI
1. Why do so many homes in Ann Arbor have basement water problems?
Many homes in Ann Arbor are built on dense clay soil, which drains very slowly. During heavy rains or snowmelt, water can build up around foundations instead of soaking into the ground, increasing hydrostatic pressure and leading to leaks, seepage, and foundation cracks.
2. How does clay soil affect basement waterproofing?
Clay soil expands when wet and holds water against your foundation walls. This constant moisture pressure is one of the main causes of foundation cracks, wall bowing, and basement leaks in Ann Arbor homes. Effective waterproofing systems must relieve this pressure and redirect water away from the foundation.
3. What stormwater solutions help prevent basement flooding in Ann Arbor?
Proper stormwater management is key. Solutions often include foundation drain systems, sump pumps, exterior drainage improvements, downspout extensions, regrading, and underground discharge lines that move water safely away from your home — even during Michigan’s heaviest storms.
4. My yard stays soggy after it rains. Could this affect my basement?
Yes. Standing water in your yard is a sign of poor soil drainage, which is common in the Ann Arbor area. When the ground becomes saturated, water can seep toward your foundation and into your basement. Addressing surface drainage and subsurface water flow helps protect both your yard and your home.
5. What are signs my Ann Arbor home needs basement waterproofing?
Common warning signs include:
- Damp or musty basement odors
- White mineral deposits (efflorescence) on walls
- Water stains or peeling paint
- Cracks in foundation walls or floors
- Water after heavy rain
These symptoms often point to drainage problems related to local soil conditions.
6. Will installing a sump pump solve my water problem?
A sump pump is an important part of many waterproofing systems, but in areas with heavy clay soil like Ann Arbor, it works best alongside interior drainage channels and exterior water management. A full system ensures water is collected and discharged efficiently.
7. Can poor grading around my home cause basement leaks?
Absolutely. If the ground slopes toward your house instead of away, rainwater collects near the foundation. Regrading and extending downspouts are common stormwater solutions that reduce pressure on basement walls.
8. How do you waterproof basements in older Ann Arbor homes?
Older homes often lack modern drain tile systems. Waterproofing may involve installing interior perimeter drains, sump pump systems, vapor barriers, and exterior drainage improvements to manage groundwater and prevent recurring moisture problems.
9. How long does basement waterproofing take?
Most interior drainage and sump pump systems can be installed in 1–3 days, depending on the size of the basement and severity of water issues. Exterior excavation or complex drainage corrections may take longer.
10. Do you provide basement waterproofing services throughout the Ann Arbor and surrounding area?
Yes. We serve homeowners in Ann Arbor, Saline, Chelsea, Dexter, Brighton, Canton and surrounding Southeast Michigan communities, addressing local soil conditions and stormwater challenges unique to this region.
