Foundation Waterproofing
Foundation Waterproofing in Eau Claire, WI
Your foundation is the one part of your home you can't afford to let water win against. When water pools against the foundation and saturates the soil around it, it doesn't just end up in your basement — over time it works on the structure itself, finding cracks, freezing inside them, and putting steady pressure on the walls. Eau Claire Drainage & Waterproofing protects your foundation from the outside in, with exterior waterproofing, foundation drainage, and grading that moves water away before it can do damage. Licensed, insured, and starting with a free inspection.

Warning signs
Signs of a Foundation Water Problem
Water problems at the foundation often show up at the structure before they show up as a flooded basement. Keep an eye out for:
- Water pooling or standing against the foundation after rain or snowmelt
- Cracks in the foundation walls — horizontal, vertical, or stair-step in block
- Walls that look like they're bowing, leaning, or shifting inward
- Efflorescence (white residue) or damp patches on the foundation wall
- Gaps opening up around windows and doors, or where walls meet
- Soil that has settled or pulled away from the foundation
- Water making its way into the basement through the walls or floor
Foundation issues tend to get worse — and more expensive — the longer they go. Catching the water early is what keeps a minor crack from becoming a structural repair.
Why it matters
Why Water Against Your Foundation Causes Damage
A little water near the foundation now and then isn't the problem — water that collects and sits there is. Here's what it does, and why our climate makes it worse.
Hydrostatic pressure
When the soil around your foundation is saturated, it creates hydrostatic pressure — the constant push of standing water against the walls below grade. That pressure forces water through cracks and porous concrete, and over time it can bow or crack foundation walls that weren't built to hold back that much force. Our heavy clay soil makes it worse by trapping water against the wall instead of letting it drain away.
The freeze-thaw cycle
This is where Wisconsin winters do real damage. Water that has soaked into a crack or is sitting against the foundation freezes, expands, and pushes the crack wider — then thaws, refills, and freezes again. Every cycle makes existing cracks bigger and can open new ones. A foundation that's chronically wet going into winter takes a beating by spring.
Soil movement
Clay soils swell when they're wet and shrink when they dry. That constant expansion and contraction around your foundation puts uneven pressure on it, which can lead to settling, cracking, and shifting over time. Keeping the soil around the foundation from getting saturated in the first place is one of the best things you can do for the structure.
Our solutions
How We Waterproof and Protect Your Foundation
Protecting a foundation is about stopping water from reaching it and sealing it where it's vulnerable. Depending on what we find, that can involve work on the outside, the inside, or both.
Exterior waterproofing membrane
The most thorough protection comes from sealing the foundation from the outside. We excavate down along the foundation wall, clean and prepare it, and apply a waterproof membrane that keeps water from penetrating the wall at all. Because it requires digging out around the foundation, this is seasonal work in our climate — but it's the most complete defense there is.
Foundation drainage (footing drains)
A footing drain — also called a foundation drain or drain tile — is perforated pipe installed at the base of the foundation that intercepts water before it can build pressure against the wall and carries it safely away from the home. Installing or restoring a proper footing drain is one of the most effective ways to relieve hydrostatic pressure on the structure.
Grading and surface water control
A lot of foundation water starts at the surface. We regrade the soil so it slopes away from the house, extend downspouts to discharge roof runoff well away from the foundation, and add yard drainage where water collects, so it never reaches the foundation in the first place. These are often the most cost-effective fixes.
Foundation crack repair
Cracks are both a structural concern and a water entry point. We seal and repair them — often by injecting polyurethane or epoxy through the full thickness of the wall — to close the path for water and help protect the integrity of the foundation.
Interior drainage, when it fits
In some cases the right complement is an interior system — interior drain tile and a sump pump inside the basement — to capture and remove any water that still gets through. We'll tell you whether your situation calls for exterior work, interior work, or a combination.
Prevention
Keeping Water Away From Your Foundation
The cheapest foundation protection is the water that never reaches it. A few things make a big difference: gutters and downspouts that actually carry roof water away from the house instead of dumping it at the base of the wall; soil graded to slope away from the foundation rather than toward it; and drainage for any low spots in the yard where water pools and soaks toward the structure. When we inspect, we look at all of it — because solving a foundation water problem often starts several feet away from the foundation itself.
Cost
How Much Does Foundation Waterproofing Cost in Eau Claire?
It depends on what the foundation needs. Regrading and extending downspouts is a modest fix. Installing a footing drain or repairing cracks is a larger job. Full exterior excavation and membrane waterproofing is the most significant investment, because of the digging involved. The condition of your foundation, how the water is reaching it, and the scope of the solution all determine the price. We inspect first, explain exactly what we find, and give you an upfront quote before any work starts — and if the fix is a simple one, we'll tell you.

FAQ
Foundation Waterproofing FAQs
How do I stop water from pooling against my foundation?
Usually it comes down to managing surface water and drainage — regrading the soil to slope away from the house, extending downspouts to discharge well away from the foundation, and adding drainage where water collects. In some cases a footing drain is needed to relieve pressure below grade. A free inspection will identify exactly why water is collecting and the right fix.
What's the difference between foundation waterproofing and basement waterproofing?
They overlap, but the focus is different. Foundation waterproofing protects the structure itself — sealing the foundation from the outside, relieving water pressure against it, and keeping water away with drainage and grading. Basement waterproofing focuses on keeping the basement interior dry, often with interior drain tile and a sump pump. Many homes benefit from both, and we'll recommend the right mix.
Can you waterproof a foundation from the outside?
Yes — exterior waterproofing is the most thorough option. We excavate along the foundation wall, seal it with a waterproof membrane, and install or restore a footing drain to carry water away. Because it involves excavation, it's seasonal work in our climate.
How serious are foundation cracks?
It depends on the type and cause, but cracks are worth taking seriously — they're both a structural concern and a path for water, and our freeze-thaw cycles tend to make them worse over time. We can assess the cracks during a free inspection and recommend whether they need repair.
Do I need exterior or interior waterproofing?
It depends on where the water is and what's happening to the foundation. Exterior work stops water before it reaches the wall and offers the most complete protection; interior work captures water that's already getting through. Many homes are best served by a combination — our inspection determines which.
How much does foundation waterproofing cost in Eau Claire?
It ranges widely depending on the solution — from regrading and downspout work on the low end to full exterior excavation and membrane on the higher end. We inspect first and give you an upfront price before any work begins.
