SHORE GUARD

Protect your shoreline from erosion, wave action, and ice damage with CMI ShoreGuard vinyl sheet pile seawall systems.

Shoreline Solutions

STOP SHORELINE
EROSION.

Iowa waterways are hard on shorelines. Wave action, boat wakes, ice, and seasonal flooding all take their toll. We install CMI ShoreGuard vinyl sheet pile seawall systems, which weigh 75% less than steel, are corrosion resistant, and require little to no maintenance. Engineered for flood protection on landmarks like the Jefferson Memorial.

How It Works

A wall that holds the line, below and above the water.

Vinyl sheet pile interlocks panel to panel and drives deep into the bank. The wall does its structural work below the waterline, then stays low and quiet above it. The same system protects a backyard shoreline, stabilizes a steep grade, or forms a full cut-off barrier.

Why Shore Guard

Built for the water, designed for the view.

Wave Action Protection

Absorbs boat wakes and open-water chop so your bank stays put.

Ice Damage Prevention

Vinyl flexes in seasonal freeze cycles instead of splitting like timber.

Erosion Control

Creates a permanent barrier against the slow loss of shoreline.

Low Profile Design

Stays visually recessive; the view is of the water, not the wall.

Clean Installation

Site-specific engineering, minimal disruption to existing landscaping.

Decades of Service

UV-stabilized vinyl and stainless hardware built for a 50-year horizon.
