Cournaya’s Land Enhancement installs and replaces culverts so water can pass under driveways and crossings instead of washing over them. We focus on proper sizing, slope, and backfilling so your culvert works the way it should and your access points stay safe and stable.

Signs Your Culvert Needs Attention

When a culvert is undersized, damaged, or plugged, water doesn’t stop-it simply finds another route. Often that route is over your driveway or around its edges, causing erosion, soft spots, and even complete washouts. Ignoring a failing culvert usually means more damage and higher repair costs later.

  • Water flowing over the driveway instead of through the pipe
  • Sinkholes, washouts, or soft spots near the crossing
  • Visible rust, crushing, or separation in the culvert
  • Standing water in the ditch that never seems to drain

Replacing or installing the right culvert restores flow and protects your driveway or access point from long-term damage.

How We Install and Replace Culverts

We start by looking at the drainage area, ditch or swale, and any requirements that may apply in your area. For replacements, we remove the old pipe and any unstable material around it. For new installations, we excavate the trench, set the culvert at the proper grade, and then backfill and compact around it to support the crossing above.

  • Assess drainage needs and existing ditch or swale conditions
  • Remove damaged or undersized culverts when needed
  • Install new pipe at the correct elevation and slope
  • Backfill, compact, and shape the driveway or crossing
  • Finish-grade the surrounding area to blend with existing ground

Our goal is a clean, functional crossing that lets water pass freely while keeping your driveway or lane solid underfoot and under tire.

Our Guarantee to You

We stand behind the work we do. Our guarantee is simple: we will show up when we say we will, do the work we agreed to, and walk the job with you before we leave. If something reasonable needs to be addressed related to the work we just completed, we will talk it through and make a plan to make it right.

Our Workmanship Warranty

Outdoor work is always at the mercy of weather and existing site conditions, but we do not disappear when the equipment leaves. If you have concerns about the workmanship on a recent project, contact us. We will review the site, explain what we are seeing, and discuss any adjustments that may be appropriate based on the original scope of work.

Need a Culvert Installed or Replaced?

If water is overtopping your driveway, eroding the edges, or your culvert is clearly failing, it’s a good time to act. Contact Cournaya’s Land Enhancement to discuss your situation, and we’ll look at the site, recommend the right culvert solution, and outline the cost before any work begins.

How Our Service Process Works

Step 1: Talk Through the Project

Every job starts with a conversation. You tell us what is going wrong, how you use the property, and what you would like to change. We ask questions, look at any photos you have, and when needed schedule a visit so we can see the ground in person.

Step 2: Walk the Site and Plan the Work

On site, we walk the area with you, point out problem spots, and talk through options. We explain what we recommend, why we recommend it, and how it will be done so you understand the plan before any equipment moves.

Step 3: Do the Grading and Site Work

On delivery day, we bring the material with trucks sized for your property and access. We place piles where you can easily reach them with equipment or wheelbarrows, or where we will be grading if we are handling the spreading.

Step 4: Review the Results Together

After delivery, we are available to answer questions about how to spread, compact, or maintain the material. If you decide you would like help with grading or additional work after seeing it on site, we can talk about next steps and schedule follow-up services.

Frequently Asked Questions

The correct culvert size depends on how much water needs to move through the ditch and any requirements set by local authorities or road agencies. We’ll look at the drainage area, upstream and downstream conditions, and any guidelines that apply, then recommend an appropriate pipe size for your crossing.

In many cases, yes. We can remove the damaged culvert, install a new one, and rebuild just the section of driveway above it. If the damage has spread farther, we’ll explain what areas need repair so the crossing is fully supported and safe to use.

Most typical residential culvert projects can be completed in about a day, depending on the length of the pipe, depth, and site access. More complex drainage situations may take longer. We’ll give you a realistic schedule when we look at the site and plan the work.
