SeaShield 2020SP™ System
A petrolatum system for protection of sheet piles, comprising of HDPE jacket with welded supporting bars. Used with Denso SeaShield Primer, Denso™ Marine Piling Tape, Denso Mastic™, wall attachment spines, foam blocks and 316 stainless steel fasteners for tensioning and attachment of jacket to wall attachment spine.
The SeaShield 2020SP™ System can be used on Z-piles, U-piles and combined walls of all sizes and types. It can accommodate and encapsulate tie rod heads and, subject to specific design, can be used on most walls with fenders, ladders, drainage outlets, cathodic protections hangers, waling beams or other features. The system is suitable for harbours, ports, channels and seawalls in marine environments.

Product FAQ
What is the expected life of the 2020SP system?
The system is based on the proven SeaShield 2000FD system. More specifically, it is based on the 2000FD system as applied to H-piles or octagonal piles, which also use foam blocks to ‘round out’ the pile. These systems have been proven over decades of use to provide a life of 25+ years while preventing virtually all corrosion.
In comparison, painted systems are expected to last for 6-8 years and often prematurely fail in marine environments. This will allow corrosion to continue wherever the coating breaks down – particularly in existing pitted areas.
Is the 2020SP system easy to apply?
Yes, the SeaShield 2020SP system is easily applied by trained applicators and does not require specialised equipment. A boilermaker is required to attach the system using 5mm fillet welds. Denso can provide training to contractors or staff of the asset owner. Denso will provide full installation instructions customised to the project as well as templates for inspection and test plans. Surface preparation requires only removal of marine growth and loose corrosion. A high-pressure water blast followed by a quick scrape is typically the most efficient way to achieve this.
