River & canal

River & Canal Seawalls

Moving water and narrow waterways are a different problem than an open lake. River and canal walls tend to work hard every single day.

Conditions that shape these projects

  • Current that works constantly at the base of the wall.
  • Boat wake in canals, often reflected back and forth between walls.
  • High-water events and rapid level changes on rivers.
  • Debris impact during floods.
  • Continuous walls with neighbors on both sides and very little room between them.

Canal properties

Canal lots frequently have a wall running the full width of the property, tied directly into the neighbors' walls, with a dock or lift attached. Work in that setting has to account for what happens at the property lines and for how equipment can even get to the water.

Riverfront properties

Riverfront walls often deal with undercutting at the toe and washout behind the wall after high water. If you have noticed changes following a flood event, that timeline is useful information for a provider.

A note on materials and construction

Different projects may use different materials and construction systems — steel, vinyl/composite, concrete and timber are all common. Appropriate options can depend on the property, water conditions, project requirements and applicable local requirements. A qualified provider can evaluate the specific project. SeawallQuote.com does not recommend a material, determine structural requirements or provide engineering advice.
