Our Services
From the first dig to the final seal, Seneca Foundations handles every phase of your foundation project with precision and care. One crew, one call, one company.

Poured Concrete Foundations
The backbone of every strong structure
Poured concrete foundations are the gold standard in residential and commercial construction. At Seneca Foundations, we specialize in cast-in-place concrete walls, footings, and retaining walls engineered specifically for Western Pennsylvania soil conditions and weather patterns. Every pour is built to last decades.
What We Provide
- Full basement foundations for new home construction
- Crawl space and slab-on-grade foundations
- Retaining walls and stem walls
- Garage and accessory structure foundations
- Multi-story commercial foundation systems
- Frost-protected shallow foundations
The Seneca Advantage
We use the Western Forms aluminum forming system, which we own outright. That means no rental delays and a precision wall finish on every pour. Our experienced crews deliver plumb, square, and level foundations that make the framing crew's job easier from day one.

Excavation & Site Preparation
Getting your site build-ready from the ground up
Before a foundation can be poured, the site needs to be properly prepared. Seneca Foundations handles complete excavation and site preparation for residential and commercial projects throughout Butler County and Western PA. Our experienced operators and heavy equipment fleet get your lot ready for construction on schedule.
What We Provide
- Foundation excavation and overdig
- Lot clearing and grading
- Driveway and access road cutting
- Topsoil stripping and stockpiling
- Backfill and compaction
- Rough and finish grading
The Seneca Advantage
Our operators know Western PA terrain. Whether your lot is flat farmland in Harmony or a steep wooded hillside in Cranberry Township, we have the equipment and experience to excavate safely and efficiently. We coordinate excavation with foundation work so there are no gaps in your project timeline.

Utility Installation
Water, sewer, gas, electric, and drainage done right
Utility installation is one of the most critical phases of site work. Seneca Foundations handles water, sewer, gas, electric, and storm drainage installation as part of our turnkey foundation package. By keeping utilities in-house, we eliminate scheduling conflicts between multiple subcontractors and keep your project on track.
What We Provide
- Water service line installation
- Sanitary sewer line installation and connections
- Natural gas line trenching and installation
- Electric conduit and underground service
- Storm drainage systems and catch basins
- Utility trench backfill and compaction
The Seneca Advantage
When one crew handles both the foundation and the utilities, things line up. Penetrations are in the right place, elevations are correct, and inspections pass the first time. Our crews coordinate every utility run with the foundation plan so there are no surprises when the plumber and electrician show up.

Concrete Line Pumping
Precision placement for every pour
Not every foundation pour is straightforward. When access is tight, distances are long, or the job calls for precise placement, concrete line pumping is the answer. Seneca Foundations operates modern line pump equipment to deliver concrete exactly where it needs to go, quickly and efficiently.
What We Provide
- Line pump service for residential and commercial pours
- Hard-to-reach foundation walls and footings
- Elevated slab pours and upper-story work
- Long-distance concrete placement
- Precision placement for complex formwork
- High-volume and continuous pour capability
The Seneca Advantage
Our line pump operators work hand-in-hand with our forming crews. Because we control both the formwork and the pump, we can coordinate the pour sequence for maximum efficiency and minimum waste. Faster pours mean better concrete consolidation and a stronger finished product.

Waterproofing & Drainage
Keeping your basement dry for the long haul
A foundation is only as good as its waterproofing. Western Pennsylvania gets significant rainfall and snowmelt, which makes proper waterproofing and drainage essential for every below-grade structure. Seneca Foundations installs complete waterproofing and drainage systems that protect your investment for decades.
What We Provide
- Spray-applied and sheet membrane waterproofing
- Interior and exterior French drain systems
- Foundation drain tile installation
- Sump pit and discharge line installation
- Dimple board drainage mat application
- Grading and surface drainage solutions
The Seneca Advantage
We waterproof every foundation we pour because we know how important it is in this climate. Our crews apply waterproofing membranes while the forms are still fresh-stripped, ensuring complete coverage and proper adhesion. We install drain tile and gravel before backfill so the drainage system is fully functional from day one.

Total Station Layout
Pinpoint accuracy on every foundation
Accuracy starts before the first shovel hits the ground. Seneca Foundations uses total station surveying equipment and GPS-guided layout technology to establish precise foundation locations, elevations, and dimensions. This level of precision ensures your structure is exactly where it should be, every time.
What We Provide
- Building location and setback verification
- Foundation corner staking and layout
- Elevation benchmarks and grade control
- As-built surveys and documentation
- Complex geometry and angular layout
- Multi-structure site coordination
The Seneca Advantage
We lay out every foundation we pour using total station equipment. That means your foundation corners are within fractions of an inch, your walls are square, and your elevations are dead-on. Builders and general contractors trust our layout work because it translates directly into easier framing and fewer callbacks.
