New Three-part Structural Repair System Doubles the Strength of Original Timber
Piles
Denso North America recently introduced the SeaShield Series 400 Marine System,
a structural repair system designed to double the strength of original timber piles.
The three-part system is an encapsulation system that not only protects submerged
timber piles from aggressive saltwater environments and marine borers, but also
strengthens deteriorated piles with a durable, lightweight, non-corrosive reinforcement.
The Denso SeaShield Series 400 consists of three parts – the SeaShield Fiber-Form
Jacket, the high-strength C-Grid 450 carbon-fiber grid and either SeaShield 510
UW Grout (cementitious) or SeaShield 550 Epoxy Grout. This system provides
a non-corrosive reinforcement to the pile, and offers reduced weight compared to
steel reinforcements. The system has been independently tested by Texas A&M
University’s Department of Civil Engineering, Structural and Materials Testing Laboratory.
The Series 400 is designed for easy installation, with a high tensile strength.
During installation, the C-Grid 450 is wrapped around the pile then the SeaShield
Fiber-Form Jacket is positioned around the pile and the C-Grid 450. Once securing
the items in place, the UW Grout or the Epoxy Grout is then pumped into the jacket.
The grid requires less grout cover when compared to steel reinforcement.
"This system was designed with two major objectives," said Jeff Baker, Regional
manager for Denso North America. "First, to strengthen timber piles, with
a lightweight, easy-to-install reinforcement. This system doubles the strength
of the original timber pile. Second, it was designed to provide protection
for existing piles from the combined effects of bacteria, fungi, aquatic insects,
and wear and tear caused by tidal currents."
Denso North America, the leaders in corrosion prevention and sealing technology,
has offices throughout the world and is a wholly owned subsidiary of Winn &
Coales International. Originally established in London, England in 1883, Denso
is the first and original manufacturer of petrolatum tape, which was developed over
80 years ago for the "Long Life Protection" of buried steel pipelines against corrosion.
Denso's anti-corrosion and sealing products have a proven track record of solving
problems in all kinds of challenging environments worldwide, above or below ground
and underwater.
