Culvert Repair &Rehabilitation
Nationwide culvert repair contractor specializing in large diameter culvert repair and trenchless culvert rehabilitation. Cost-effective, minimally invasive polyurea spray coatings that stop corrosion, restore structural integrity, and extend culvert life by decades — without full replacement.
Why Culvert Repair & Rehabilitation Matters
Aging and damaged culverts can lead to erosion, flooding, road failures, and safety hazards. ASFI Construction provides cost-effective, minimally invasive culvert repair and culvert rehabilitation — including large diameter culvert repair — for DOTs, railroads, municipalities, and private owners nationwide.
Fast-Curing Protection
Highly durable lining systems that stop corrosion and restore structural integrity
Custom Engineering
Tailored systems based on culvert size, shape, and condition
Minimal Downtime
Disruptive highway closures and expensive replacements are a thing of the past
Long-Lasting Protection
Resistant to corrosion, abrasion, and chemical exposure
Large Diameter Culvert Repair
Large diameter culverts present some of the toughest infrastructure challenges — full replacement means major excavation, lane closures, and weeks of disruption. ASFI's trenchless culvert repair approach is built for exactly these projects.
Built for Big Pipe
Our SIPP polyurea systems are spray-applied from inside the culvert, which makes them particularly well-suited to large diameter culvert repair where worker access is feasible and traditional slip-lining would sacrifice too much hydraulic capacity.
All Shapes & Materials
We repair round, elliptical, arch, and box culverts in corrugated metal pipe (CMP), reinforced concrete pipe (RCP), and structural plate. The seamless polyurea lining conforms to complex geometries that rigid liners can't.
Restores Structure
For fully corroded large diameter culverts, polymeric SIPP can dramatically increase load-carrying capacity — bringing failed culverts back into service without the cost, delay, and traffic impact of open-cut replacement.

Spray In Place Pipe (SIPP) is a trenchless technology pipe renewal method that sprays layers of polymeric lining inside deteriorated pipes to provide extended service life.
Superior Performance
Polymeric SIPP materials offer higher chemical resistance, corrosion protection, and tensile strength compared to traditional methods.
Structural Enhancement
Research shows polymeric SIPP can increase the service load carrying capacity of fully corroded culverts by up to 800%.
Environmental Benefits
Environmentally friendly with smaller construction footprint and compatibility with complex geometries.
