Rion Waterproofing is a Wisconsin team of basement waterproofing, crack injection and floor coating specialists, led by owner Ryan Harrison.

Built on integrity, led by experience

Rion Waterproofing was founded in 2015 by Ryan Harrison, a contractor with over 15 years of experience in Southeastern Wisconsin. Every job still carries his name, so we stand behind our work.

Today our crews handle the whole concrete job: stopping leaks, repairing cracks and coating the finished floor. Rion Injection, our concrete crack injection team, serves homes and commercial buildings across Wisconsin, eastern Minnesota, eastern Iowa and northern Illinois.

We started as a Milwaukee-area waterproofing company and grew by doing the repair, not just the patch. Today that means one owner-led team for the leak, the crack and the floor. Our focus is concrete: finding why it is failing and fixing it so it stays fixed.

Basement waterproofing that fixes the cause.

Water gets in through cracks, joints and the seam where the floor meets the wall. We start by finding the source, then fix it with interior and exterior drain tile, sump systems, wall repair and mold remediation. You get a plan built for your home, a clear price, and a dry basement you can actually use.

Most of our homeowner calls start with a wet basement. Many of them end with a crack that needed injecting or a floor that needed coating.

Concrete crack injection for homes and commercial buildings.

Injection seals a crack from the inside and stops water without digging up your yard. We use it on poured basement walls, but also on parking structures, bridges, churches, apartments and underground storage.

Commercial and municipal work is a growing part of what we do, and our crews are used to working around people who still need to use the building.

Garage floor coatings built to last.

Coatings only last on sound concrete, so we repair cracks and prep the surface first. Then we install polyaspartic or polyurea floor coatings in garages, basements, patios, pool decks and commercial floors.

The result is a floor that is easy to clean, resists stains and holds up to traffic. Because the same crew did the prep, you deal with one company from start to finish.
