When pipeline operators discover an exposed pipeline, an unstable stream crossing, or erosion threatening a right-of-way, they need more than a consultant or material supplier. They need an experienced construction partner capable of mobilizing quickly, managing the entire project, and delivering a long-term solution.

That is where Submar stands apart.

For more than 40 years, Submar has provided specialized onshore construction services focused on erosion remediation, pipeline protection, and infrastructure stabilization throughout the United States. Having completed more than 2,200 projects across 45 states, Submar has become a trusted construction partner for the energy industry. Serving 90% of the nation’s major pipeline operators, the company is known for safely executing complex erosion remediation, pipeline protection, and infrastructure stabilization projects in some of the most challenging environments across the United States, earning its reputation as THE Exposed Pipeline Remediation Experts.

Construction Is at the Core of What We Do

At Submar, construction execution is at the heart of every project. Our team combines field-proven construction expertise with surveying, engineering support, permitting, project management, and long-term asset protection strategies to deliver complete turnkey solutions. From initial site assessment through final construction and performance monitoring, we manage every phase of pipeline remediation projects to ensure safe, effective, and lasting results.

Our crews routinely perform:

• Pipeline exposure remediation
• Stream and river crossing stabilization
• Erosion control installation
• Bank stabilization projects
• Site preparation and restoration
• Slope stabilization
• Water management improvements
• Articulated concrete mat installation
• LPSTP installation
• MSE wall construction
• Steel sheet pile installation

Every project is managed from initial assessment through final restoration, providing clients with a single contractor responsible for delivering results in the field.

From Problem Identification to Construction Completion

Erosion issues can develop gradually or appear suddenly after major weather events. Stream migration, bank failures, washouts, and changing water flow patterns can expose pipelines and threaten infrastructure integrity.

Submar’s approach focuses on understanding the site conditions and then executing the appropriate construction solution. Our team conducts field assessments, develops practical remediation plans, secures required permits, coordinates materials and equipment, and mobilizes experienced crews to complete construction safely and efficiently.

For pipeline operators, that means fewer contractors to manage, reduced project delays, and a single point of accountability throughout the project lifecycle.

Experienced Crews. Proven Solutions.

Submar’s construction crews work in some of the most challenging environments in the energy industry, including remote rights-of-way, river crossings, wetland areas, and environmentally sensitive locations.

Our construction capabilities include implementing a variety of proven erosion control methods, including:

Articulated Concrete Mats

Submar’s articulated concrete mat systems provide durable protection for exposed pipelines and vulnerable streambeds. The mats conform to changing terrain while protecting critical infrastructure from continued erosion. They also support natural vegetation growth, helping sites blend into the surrounding environment over time.

Longitudinal Peaked Stone Toe Protection (LPSTP)

LPSTP systems are designed to stabilize streambanks and redirect hydraulic energy away from vulnerable pipeline crossings. These projects require precise construction techniques and experienced project management to ensure long-term performance.

Bendway Weirs and Bank Stabilization

Submar crews construct bendway weirs and bank protection systems that help control channel migration, reduce erosion, and protect pipeline rights-of-way from future exposure risks.

Mechanically Stabilized Earth (MSE) Walls

Where slope failures and embankment instability threaten infrastructure, Submar constructs MSE wall systems that provide structural support and long-term erosion resistance.

Safety Drives Every Project

Construction performance starts with safety.

Submar maintains a comprehensive safety management system supported by behavior-based HSE processes, daily job hazard assessments, safety audits, learning management programs, and industry-recognized compliance systems. This commitment helps ensure our crews perform work safely while meeting client expectations for quality and reliability.

Nationwide Construction Support

With a nationwide presence and extensive experience across diverse geographic conditions, Submar is equipped to support projects ranging from small exposure repairs to large-scale erosion remediation programs. Our ability to self-perform critical construction activities, manage logistics, coordinate permitting, and provide project management services allows clients to move from problem identification to completed remediation with confidence.

Building Solutions That Last

Pipeline operators across the country trust Submar because we do more than identify problems. We build solutions.

From exposed pipeline remediation and streambank stabilization to complex erosion control projects, Submar delivers the experienced crews, proven installation methods, and construction expertise necessary to protect critical infrastructure for the long term.

When erosion threatens pipeline integrity, Submar brings the equipment, expertise, and construction capabilities to get the job done safely, efficiently, and built to last.
