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

  • check_circleLine pump service for residential and commercial pours
  • check_circleHard-to-reach foundation walls and footings
  • check_circleElevated slab pours and upper-story work
  • check_circleLong-distance concrete placement
  • check_circlePrecision placement for complex formwork
  • check_circleHigh-volume and continuous pour capability

workspace_premiumThe 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

  • check_circleSpray-applied and sheet membrane waterproofing
  • check_circleInterior and exterior French drain systems
  • check_circleFoundation drain tile installation
  • check_circleSump pit and discharge line installation
  • check_circleDimple board drainage mat application
  • check_circleGrading and surface drainage solutions

workspace_premiumThe 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.
