Durable Seawalls to Protect the Shores of St. Clair Shores
Erosion is a real concern for waterfront property owners on Harsens Island. With fluctuating water levels, strong currents, and seasonal storms, seawall installation provides a critical barrier between land and water. It’s an investment in both safety and property value.
We construct:
- Steel sheet pile seawalls – Ideal for long, straight shorelines with high wave exposure
- Vinyl/PVC seawalls – Cost-effective, corrosion-resistant, and suitable for most residential properties
- Concrete seawalls – Engineered for heavy-duty performance, common in public or commercial applications
- Riprap revetments – Natural rock barriers that absorb wave energy and blend with the landscape
planning & permitting
We start with an environmental site review to determine your shoreline’s erosion patterns, soil stability, and required wall height. Permitting with EGLE is mandatory on Harsens Island due to its ecologically sensitive wetlands, and we handle the entire process, including soil and water impact documentation.
Customized to Fit Your Needs
Depending on the exposure and water dynamics near your property, we may recommend steel sheet piling, vinyl walls, or composite alternatives. From residential backyards to commercial marinas, our seawalls are built to last and look great.
Our Process
- Initial Consultation: Analyze shoreline, property grade, and material requirements.
- Design & Engineering: Build specs are created based on site conditions and water forces.
- Permitting & Approvals: EGLE and township permits are obtained.
- Installation: Wall is built, anchored, and backfilled for drainage and support.
Benefits of seawall installation
- Erosion Defense: Seawalls hold back soil and absorb wave energy, preserving your land.
- Water Intrusion Prevention: Reduce the risk of flooding and groundwater seepage into basements or crawl spaces.
- Long-Term Value: A properly built seawall increases property longevity and resale appeal.
- Clean Appearance: Modern seawalls can be aesthetically integrated into your landscaping.
