Exterior Waterproofing in Union, OH

When water reaches your foundation from the outside, through poor grading, a failed membrane, or saturated soil, the fix belongs outside too, not just masked from the inside.

Why Choose Our Specialized Exterior Waterproofing in Union, OH

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.

Professional Exterior Waterproofing technician working in Union, OH
1

Excavation & Membrane Expertise

Certification covers grading assessment and rubberized membrane application to manufacturer spec, verified on every job.

2

Local Grading Assessments

Local crews understand your region's soil composition and typical frost depth, both of which affect excavation planning significantly.

3

Itemized Excavation Pricing

No surprise charges for unexpected utility lines or rock encountered during excavation — those are flagged and discussed first.

4

Commercial-Grade Membrane Systems

Drainage board over the membrane channels water to the footing drain rather than letting pressure build against the wall.

Our Exterior Waterproofing Service Lineup

We don't run a one-size-fits-all playbook — every exterior waterproofing job starts from these core service components, adapted to what your property actually needs.

Foundation Excavation & Membrane Application

We excavate along the affected wall section down to the footing, prep the surface, and apply a rubberized membrane rated for permanent below-grade exposure. This is the most thorough exterior fix available and typically carries the longest service life.

Footing Drain Installation & Repair

A footing drain intercepts groundwater at the base of the foundation and carries it away before it can build pressure against the wall.

Grading & Drainage Correction

Soil sloping toward the foundation sends every rainfall straight at your basement wall, regardless of how good the membrane below is.

Window Well Drainage Systems

We install well drains tied into the footing drain system with a clear cover to reduce debris.

Exterior Crack & Joint Sealing

Cracks and cold joints exposed during excavation get treated directly from the outside before the membrane goes over them.

Frequently Asked Questions

The questions Union customers ask us before booking exterior waterproofing service.

How quickly can a crew start an exterior assessment in Union, OH?+
Response time depends on the assessment scope needed, but active water intrusion moves up the schedule.
Do you provide upfront, flat-rate pricing?+
Yes, quotes are itemized by excavation footage and membrane material, in writing before any digging starts.
Why would I need exterior work if interior injection already stopped the leak?+
Some situations genuinely only need interior work; we'll tell you honestly whether yours calls for exterior excavation.
How long does exterior waterproofing take?+
We'll give you a realistic project timeline during the written quote, including any landscaping restoration.
Will excavation damage my landscaping?+
Significant landscape features are discussed during the quote so there are no surprises.
Is exterior waterproofing covered by a warranty?+
Yes, membrane and footing drain work carries a written warranty against failure at the treated wall section.
Do you need to remove my patio or deck to excavate?+
Where possible, we work around existing hardscape, but a patio or deck directly over the excavation zone may need temporary removal, which we'll explain clearly upfront.
How deep does the excavation typically go?+
We confirm exact excavation depth during the assessment based on your specific foundation drawings or an on-site measurement.
