Epoxy Encapsulation

H-Piles at International Shipping Facility after Encapsulation.

Epoxy encapsulation can effectively prevent continued corrosion of marine structures. 

Substructure’s in-house epoxy encapsulation services include epoxy, customized fiberglass jackets, and clamps to secure jackets during epoxy pumping – a complete one-stop operation for world-leading corrosion protection.

Our experience using deficient, existing pumping technologies prompted us to design a unique, compact, plural-component epoxy pump for marine encapsulation services. This travel-ready, patented pump now services Substructure epoxy encapsulation projects around the world. Built for applications with specifications for 1:1 ratios, Substructure’s pump provides the highest-quality product available, part of the most complete, turnkey, epoxy encapsulation installation in the industry.

Properly applied epoxy encapsulation provides an extremely durable marine coating, with a life expectancy of 20-50 years. Epoxy encapsulation is best used in the extended intertidal zone to prevent the 3 primary types of marine corrosion from continuing to erode structures. The three major types of marine corrosion epoxy encapsulation protects structures from are oxidation, fretting, and electro-chemical (more here).  

(Under the water, cathodic protection is best used to protect metal.)

Epoxy Encapsulation Projects


Epoxy-Filled FRP Jackets

The most effective encapsulation method involves placing a fiber-reinforced-polymer (FRP) jacket, or form, around a structural member, sealing the bottom, and then filling the annular cavity with a two-part epoxy grout. 


FRP vs. Steel Jackets

Encapsulation with epoxy-filled fiber-reinforced polymer (FRP) jackets is superior to and more cost effective than with concrete-filled steel jackets or concrete-filled FRP jackets.


Effective Surface Preparation

There is little performance difference among the variety of epoxy grouts and fiber-reinforced-polymer (FRP) jackets available for marine encapsulation.
