Weir Residential Seawall
Client Type: Residential
A backyard renovation project turned into a more complex construction challenge when Ultramarine discovered voids under a neighboring foundation during the Weir seawall installation. The team solved the problem on the spot — protecting both properties — and delivered a new 80-foot seawall with a robust reinforced cap and 10 helical tiebacks.
The Challenge
The customer needed a new seawall as part of a backyard renovation. During installation, the crew encountered multiple complications including voids forming under a neighboring property’s foundation — a situation that required immediate problem-solving to prevent future erosion damage to both homes.

Scope of Work


Our Solution
Ultramarine completed the 80-foot seawall installation while simultaneously addressing unexpected voids under the neighboring foundation — going above and beyond to protect both properties and ensure long-term stability.
