CMI is the leading developer and manufacturer of high-performance, sustainable and cost-effective vinyl seawalls and bulkheads. We invented the vinyl seawall 25 years ago, and for decades we have cultivated relationships with local marine construction companies for the purposes of connecting them with homeowners in need of seawall education, installation, repair or replacement. Our ShoreGuard products remain the best selling, most trusted synthetic sheet piling in the world.
In addition to vinyl materials, CMI also offers advanced solutions in composite and aluminum sheet piling. Our components provide lasting quality in an often-overlooked area of construction, saving homeowners on costly tie-rod repair and cap maintenance.
Sheet piling must be able to withstand harsh conditions. Our non-corrosive materials save homeowners time and maintance, paying long-term dividends when compared to traditional concrete or treated wood sheet piling, which can fail after a short time. If you only want to build your seawall once, then use the best materials. Choose ShoreGuard.
