Our Culvert Repair & Replacement Services

Trenchless Rehabilitation Services

When your pipe still has good structural integrity, but leaks or cracks are starting to show, we repair it on-site instead of tearing up your property.

  • Sliplining: We insert a new, slightly smaller pipe directly into your existing damaged pipe to restore its function.
  • CIPP (Cured-in-Place) Lining: We pull a resin-saturated tube through the damaged pipe and then harden it with heat or UV light.
  • Invert Paving and Concrete Lining: If the bottom part of the pipe is the only part that’s damaged, our team can apply a reinforced concrete invert, shotcrete, or geopolymer lining.
  • Joint Sealing/Banding: If the culvert has leaking or damaged concrete joints, we’ll use internal bands or gaskets to keep out soil and prevent water seepage.

Replacement Services

If your culvert has completely collapsed, lost its structural integrity, or rusted through, we may need to fully or partially replace it.

  • Full Excavation and Replacement: We dig up the surrounding roadway or driveway, remove the old culvert, and replace it with a new one. We grade and backfill around the culvert to make sure water drains correctly.
  • Headwall and Endwall Work: Our crew will rebuild or reinforce the concrete or stone structure at the inlet, outlet, or both.
  • Permitting and Environmental Work: We take care of all required permits for your Central Coast culvert replacement, including the CDFW Streambed Alteration Agreement and any Army Corps approvals for work near waterways. When the job wraps up, we restore disturbed soil and vegetation and leave your site in good shape.

Maintenance & Preventive Services

Keeping up with routine maintenance protects your culvert from debris buildup, root intrusion, and soil erosion before small issues turn into expensive repairs.

  • Cleaning and Unclogging: We will pressure wash the inside of the culvert, cut roots that have started to grow into the sidewalls, and remove any debris that could clog the pipe.
  • Pressure Grouting: We’ll use injections to stabilize the loose soil around your culvert and fill cracks in the lining.

How We Repair & Replace Culverts

culverts-damage

1. Site Assessment & Inspection

We begin by assessing the property and inspecting the culvert. We’ll look for how severe the damage is and the condition of the surrounding soil. We’ll also check for sinkholes and blockages. Then, we’ll consider the water volume and your drainage needs.

2. Repair or Replacement Recommendation

After we assess your culvert, we’ll recommend the best path forward, whether that’s a repair or a full replacement. If repair is the right option, we’ll identify the best method for your situation. If replacement is necessary, we’ll help you choose the right material, size, and shape and walk you through the cost of each option.

3. Permitting & Utility Clearance

With years of experience navigating local permit requirements across Santa Cruz, Monterey, and Santa Clara counties, we handle grading, encroachment, and other necessary permits on your behalf. We also mark all underground utilities before we dig to prevent accidental damage to gas, water, and electrical lines.

4.  Repair or Removal Work

If we’re doing repairs to the culvert, we’ll carry this out with minimal disturbance to the surrounding areas. If we’re replacing your culvert, we’ll excavate the area, remove the old culvert, and install the new one without destabilizing the soil around it.

5.  Installation & Reinforcement

If we replace your culvert, we’ll make sure the area around it is properly graded first. This ensures that water can flow at a safe rate and in the right direction. We’ll restore and compact the soil surrounding the culvert.

6. Site Restoration & Final Inspection

We’ll clean up the surrounding area and verify proper drainage. We’ll do a final walkthrough with you to ensure that you’re satisfied with the work that we performed.

Properties We Serve

Residential

Many of the homes that we serve have culverts running under their driveways, along private roads, and in drainage ditches on their property. Over time, age, erosion, storm runoff, and vegetation can all damage these culverts. We handle your entire culvert repair or replacement project, from pulling the necessary permits to the final walkthrough.

Commercial

Commercial culverts often face higher demands than those on residential properties. Central Coast storm seasons and agricultural runoff place even more stress on commercial culverts. Here at Betz Works, we perform culvert repair and replacement in parking lots, access roads, retail centers, industrial facilities, and apartment complexes.

We’ll make sure that the work is compliant with all commercial permitting requirements. Additionally, we’ll work tirelessly to complete this work with minimal disruptions to your business operations.

Municipal

Betz Works has even earned the trust of local municipal offices, thanks to our quality of work. We’ve repaired and replaced culverts under roadways, highways, and in public drainage systems.

Much of the Central Coast area deals with aging infrastructure, including culverts. Recent storm seasons and changes in weather patterns have placed even more strain on culverts. We’ve handled multiple, large-scale projects like these throughout Santa Cruz, Salinas, Carmel Valley and many more areas.

Why Trust Betz Works?

Since 1958, three generations of our family have been helping Central Coast homeowners, business owners, and municipalities keep their drainage systems in shape. We know how heavy rainfall, shifting soil, and marine moisture wear down culverts in this region, and we know how to fix them.

When you hire us, you get:

  • A licensed, insured, and bonded crew
  • An owner on-site for every project, with 15 years of hands-on field experience
  • Full project management from permits to final walkthrough
  • Clear communication at every step

FAQs

What does a culvert actually do?

Culverts create a path for water to flow under or around roadways, driveways, and other infrastructure. They may also be bridge-like structures that can support vehicle or foot traffic while allowing water to flow underneath.

What are the most common types of culverts?

Pipe culverts are the most common type of culvert. Other options include box culverts and arch culverts.

What causes culvert damage?

Several factors can compromise your culvert over time, including:

  • Improper installation or low-quality materials
  • Neglected maintenance
  • Heavy rainfall, flooding, and storm runoff
  • Soil erosion and shifting ground
  • Root intrusion and vegetation growth
  • Age and general wear and tear
How do I know if my culvert needs repair or replacement?

Generally, we can repair culverts if they have minor damage but maintain their structural integrity. The soil around the culvert should also be stable.

In some instances, culvert repair isn’t an option. For example, if your culvert is collapsing or has been crushed, a repair simply won’t last.

Replacement is also the best option if your existing culvert cannot keep up with the amount of water that needs to flow through it.

In these cases, we can remove the damaged culvert and replace it. We’ll help you choose the right material for your drainage needs and restore the soil around it.

What repair methods do you use?
  • Cured-in-Place Pipe Lining: A tube that’s saturated in resin is inserted into the culvert, where it’s hardened by heat or UV light. This is the best option for culverts with mild structural damage.
  • Slip Lining: A new pipe gets inserted into the culvert, where it’s sealed with grout. If the existing culvert has enough stability to serve as an outer shell, this is an excellent option.
  • Spray Lining: We use a winding machine to push vinyl lining into the culvert from the entrance. This method is best used when minimal excavation is preferred.
  • Shotcreting: We spray a concrete mixture into the culvert at a high velocity, allowing it to compact and harden inside. This is the ideal choice when a culvert needs strong, structural restoration.
  • Paved Invert: If your culvert is 36” or more in diameter, a paved invert is placed into the base of the culvert to repair abrasion damage.
Who is responsible for driveway culverts near me?

Fixing your culvert early keeps water draining properly and protects the soil around it from erosion and saturation, which lowers your risk of sinkholes and costly water damage down the line.

Why is it important to repair a culvert promptly?

The property owner is generally responsible for culvert repairs. Culverts along public roads or easements may fall under county or city jurisdiction. To find out who is responsible for a culvert near you, contact your local public works department:

How do I fix erosion around a culvert?

Shrubs and vegetation can help support the soil near a culvert and prevent erosion. Loose stones and rocks, also known as riprap, may also reinforce the culvert.

What happens when a culvert fails?

A collapsed culvert leads to water pooling on the driveway or road. It may also lead to clogged creeks or streams.
