Special Projects

Specializing in Marine Construction and Underwater Projects

Underwater Resources, Inc. enjoys the challenge and rewards of performing under difficult and adverse conditions that are always present in and around the water. Whether you need inspections or restorations, our team is more than ready to help you out.


What We Do

Our projects include:

HDPE Pipeline Installations

We can work for up to 63” diameter HDPE pipelines for sanitary outfall and water conveyance systems. Fusion welding 40’ to 50’ pipe sections onshore to make up to an 8000’ continuous length of a pipeline, we can control precision alignments within narrow corridors as in water depths over up to 125’.


Diamond Wire Saw Cutting or Demolition

Using this demolition methodology minimizes debris impact and allows for faster and more economical removal or seismically retrofits of marine structures, including raw water intake towers, bridge piers, and water impoundment structures using limited and minimal above water spread equipment and support services.

Specialty Inspections

We use remote imaging equipment (ROV, Sonar) to conduct detailed UW investigations of shallow and deepwater structures, scour, and sediment level surveys. These are conducted within limited access beneath piers and pipelines or tunnels; Bathymetry, Current Velocity, and Sub-bottom Profile surveys.

Types of Testing

Destructive testing is conducted with coring to measure the compressive strength of concrete and chloride intrusion. We can also perform nondestructive testing (NDT) to measure corrosion and wastage of structural steel. It will also allow us to conduct flaw detection using UT or MT equipment and techniques.


Concrete Restoration, Leak Repair, or Substrate Stabilization

Epoxy and urethane injection of cracks and cold joints in concrete structures for rehabilitation and structural repair, sealing water leakage from groundwater intrusion or damaged pipe joints. We can also install internal pipeline joint seals up to 144” diameter pipe and culverts; soil stabilization using cement and urethane grouts beneath submerged structures.

Corrosion Protection or Seismic Upgrade of Marine Structures

UW encapsulation of steel piling and pipeline structures using corrosion-resistant or protection systems and seismic upgrade on concrete structures or caissons using fiber-reinforced polymer systems (FRP.) Installation of sacrificial anodes and impressed current cathodic protection systems.
