Bulkhead Repair/Construction

Coastal and inland bulkheads are most often referred to as vertical revetments. These man-made structures are constructed along shorelines to control property erosion, Control Water Flows and create Stable working platforms near the Waters edge.

Bulkheads should be constructed by qualified licensed, insured, and bonded contractors. We at Sterling Sub Sea work closely with our structural engineers to bring you the best Bulkhead construction services in the market.

Our Bulkhead Construction service offers the following features:

  • High-quality materials.
  • All hardware is hot-dipped-galvanized.
  • Most of our materials are supplied locally for cost savings.

Bulkhead Repair

Major and Minor repairs are our specialty. We often suggest and recommend repairs when other companies are pushing for new installation projects. We are licensed, bonded, and fully insured. Quality Workmanship and Incredible customer service are our goals. We’ll get the job done right the first time, and on time.

Is Bulkhead repair suggested?

Yes, it is. The cost of a repair versus the cost of a new Bulkhead installation is very substantial. A site evaluation from one of our experts will help to answer that question. Our first option is always a repair solution. On-site, we review structure and erosion control issues. Minor repair permits are much easier to obtain than New Installation Permits.

Furthermore, bulkheads that need repair should be on top of the list for many projects. Collapsed Bulkheads cerearte a need for extensive Salvage work and can drive the Installation Cost of a new bulkhead up significantly. Contact us today to learn more about our bulkhead repair services.

Dock Construction and Repair.

When it comes to building docks, Sterling is second to none. No job is too big or too small. We have built high-quality structures throughout the inland waterways from both the land and from the water. This includes dry bulk terminals, liquid bulk terminals, heavy-lift docks, cellular structures, sheet pile walls, marinas, and more.

Due to our vast experience, we know what a Safe, efficient dock operation should look like and work with our clients and their engineers to optimize the structure to meet their needs.

If you are looking to extend the life of an existing structure, contact us for underwater inspections and surveys. Our divers are the best in the business and know river-based infrastructure. We  can carry out an underwater inspection and provide repair solutions to make life simple.

Rest assured, we will work closely with you to find a repair that will best fit your structure and your budget.

Structural Piling

What is a Structural Pile?

Sheet piles are sections of sheet materials with interlocking edges that are driven into the ground to provide earth retention and excavation support. Sheet piles are most commonly made of steel, but can also be formed of timber or reinforced concrete.

Sheet piles are commonly used for retaining walls, land reclamation, underground structures such as car parks and basements, in marine locations for riverbank protection, seawalls, cofferdams, and so on.

How Does Piling Work?

The selection of sheet piling is dependent on factors, such as:

  • The type of work, e.g., whether it is permanent or temporary.
  • Site conditions.
  • The required depth of piles.
  • The nature of the structure.
  • The type of protection required.

We offer the following types of  piling:

Timber piles.

Timber sheet piles are generally used for short spans in temporary structures, and to resist light lateral loads. They are typically connected by tongue and groove joints, or are Round Timbers. The disadvantage of timber piles is that they require preservative treatment and can be difficult to install in soil containg a high rock or Boulder content.

Reinforced concrete sheet piles.

Reinforced concrete sheet piles are formed using precast concrete members, usually connected by tongue and groove joints. They are commonly used in permanent river dams, canals, and other marine structures. The toes of the piles are usually cut with an oblique face to facilitate easy driving and interlocking. At the same time, the heads are finished off by casting a capping beam.


Steel sheet piles.

Steel is the most common form of sheet piles as it has good resistance to high driving stresses, excellent water-tightness, and can be increased in length either by welding or bolting. They are connected by interlocking.
