Cost Efficiency
The real measure of this is not just the comparison of costs for the initial installation; you also need to figure in the costs
over the long term. Since FRP sheet piling lasts much longer than more traditional materials, the cost of repairs and replacement
is delayed.
Consistent Appearance
It is well known that wood fades over time. Paint may cover that up, but the paint color will fade as well. There is really not a lot you can do about that except continue to paint in order to keep it looking nice.
FRP sheet pile, on the other hand, holds the same beautiful appearance for a very long time.
UV Resistance
Most materials react negatively to the harmful ultraviolet rays of the sun, and it doesn't take very long for that to start
happening. When the time period is stretched out over years, the sun can do some real damage.
FRP sheet piling is designed to be resistant to this, so the effects of the sun are not as serious or as quick.
Unaffected by Marine Borers
Marine borers are small mollusks or crustaceans that live in the ocean, and their primary source of sustenance is wood. If you use wood for your seawall construction, you will almost immediately have marine borers latching on and drilling into it.This degrades the integrity and stability of the seawall over time, which defeats the whole purpose of the structure. You want your seawall to be strong enough to withstand very harsh conditions. If a marine borer comes across a seawall constructed with FRP, it just keeps moving. FRP provides no attraction at all for marine borers.
Easy Installation
FRP sheet piling provides for an easy installation, particularly compared to wood. Wood is subject to imperfections, warping, and various deformities. This can sometimes cause problems or delays at the time of the installation. Unlike wood, FRP sheet pile does not grow in nature; the components of a vinyl seawall are manufactured to some very strict and precise standards. There is virtually no room for error, so you are able to have a consistent product each time. This means an easy installation.
