Driveways, Drainage & Seasonal Services

Risha Enterprises offers reliable excavation and site services to support foundation work and general construction across Sunbury, Ohio and surrounding areas. With more than 35 years of experience in excavation and site preparation, we help homeowners, builders, and contractors create stable, code-compliant foundations for homes, pole barns, garages, workshops, and additions.



Every successful build begins with proper groundwork. From digging footers and grading pads to backfilling and rough site work, our team ensures your construction site is safe, level, and ready for the next stage. We bring the equipment, skill, and local experience to handle your excavation and foundation prep the right way—from day one.

Whether you're starting a new home build or preparing for a structural addition, we make sure the land under your foundation is solid, compacted, and properly graded.

Foundation Excavation Services

We provide precise foundation excavation for slab-on-grade, crawlspace, and basement structures. Working closely with property owners, builders, and concrete crews, we coordinate access, elevations, and backfill timing to ensure every excavation meets exact depth and slope requirements. Our services include footer trenches, foundation and pad grading, cut-and-fill work, and soil compaction—delivering reliable site preparation for garages, pole barns, outbuildings, and residential construction.

Site Grading and Pad Preparation

Before a foundation can be formed and poured, the site must be properly cleared, leveled, and graded. Risha Enterprises provides professional grading services to ensure a flat, compacted surface that meets drainage requirements and structural needs.


Grading and pad services include:

  • Pad construction for pole barns or garages
  • Final grading around foundation walls
  • Drainage slope planning
  • Access grading for trucks and construction equipment
  • Gravel pad placement for temporary construction access



We use laser-leveling and proper compaction techniques to ensure each pad or grade is ready for long-term support.

Backfill and Compaction

After foundation walls are poured and forms are removed, the area must be backfilled and compacted to protect the structure and reduce settling. We return to the site at the appropriate stage to handle careful backfilling with either native soil or imported fill as needed.


Our team ensures:

  • Proper soil placement and compaction
  • Clean grading around the foundation
  • Water runoff management to prevent erosion
  • No pressure against newly formed walls



Correct backfill is essential to the performance and drainage of any foundation. We do it right to protect your investment.

Construction Site Support

In addition to excavation and grading, Risha Enterprises provides general site services that support construction progress and efficiency. We work with builders and homeowners to improve access, manage drainage, and create a safe, organized work zone.


These services include:

  • Rough access roads and drive paths
  • Construction staging area grading
  • Clearing and debris removal
  • Site prep for sheds, concrete pads, or porches
  • Final site touch-ups after framing



Whether you're working with a general contractor or managing the project yourself, our site support helps streamline each phase of construction.

Foundations for Pole Barns and Agricultural Structures

Pole barn construction requires precise foundation support. Whether you're building with a dirt floor, gravel base, or full concrete slab, we prepare the ground to match your barn design and meet long-term performance needs.


We provide:

  • Post hole excavation and setting support
  • Pad leveling and slope adjustments
  • Concrete slab prep and edge grading
  • Trenching for utility access


Because we also build pole barns ourselves, we understand the structural needs of post-frame buildings and how to ensure the ground supports the entire structure evenly.

Our foundation and construction support services are ideal for:


  • Homeowners building custom homes or additions
  • Property owners installing pole barns or workshops
  • Contractors seeking excavation partners
  • Builders managing multiple residential projects

We work with individual clients, crews, and general contractors to provide the excavation and site services needed to keep construction moving smoothly.

Frequently Asked Questions

  • Can you work with my general contractor?

    Yes. We coordinate closely with your GC, builder, or concrete team to make sure excavation is scheduled and completed to exact project specs.


  • How deep are footer trenches typically?

    Trench depth depends on frost line requirements and local building codes. In central Ohio, most footers are set 36 inches or deeper. We follow your engineer’s or builder’s exact specifications.


  • What kind of foundations do you excavate for?

    We excavate for slab-on-grade, poured walls, crawlspaces, basement walls, and post-frame barn footings. We also offer excavation for small pads and outbuildings.


  • Do you offer grading after foundation work is complete?

    Yes. We return after forms are removed to backfill, compact, and grade the surrounding area for final use or landscaping.


  • What if I only need pad prep for a barn or shed?

    We offer standalone pad prep for pole barns, sheds, garages, and other structures. We’ll clear, level, and compact the area to match your structure’s footprint.
