Benefits of ShoreGuard® Sheet Piling

ShoreGuard® Vinyl Sheet Piling contains no toxic coatings or preservatives, is corrosion-resistant, is impervious to marine worms and will not rust, rot or crack. Vinyl seawalls are also UV-resistant, meaning they will not be damaged by the sun or fade like wood and paint.

The pictures below were taken of an exposed seawall in Corpus Christi after Hurricane Harvey ravaged the Texas Gulf Coast. This one had been built using ShoreGuard® Vinyl Sheeting Piling and survived the storm. The hurricane pulled soil out from behind the wall exposing its components but the seawall remained structurally sound and intact.

Styles of ShoreGuard® Sheet Piling

ShoreGuard® is available in both corrugated and flat panels and can be special ordered and customized to meet the specs of your job and the freshness of your timbers. McCoy’s carries a range of colors to help you achieve the look you want. You’ll want to select a color that best blends with the feel of your home and its surrounding property. Dirt type and water color should be taken into consideration when choosing a color as lighter colored panels may be stained by dark dirt, such as red clay, and muddy waters. McCoy’s currently carries gray, brown and clay panels in select stores, with additional colors available through Special Order.
