Waterfront foundations fail differently than inland foundations — saltwater corrosion, marine borers, wave-induced scour, and soft coastal soils create failure modes that standard foundation contractors are unprepared to handle. Seawall Repairs by Solid Foundations specializes in marine foundation repair for docks, boathouses, waterfront homes, seawall anchor systems, and other coastal structures — using helical pier underpinning, polyurethane grouting, and marine-grade repair methods designed for the harsh coastal environment.
Marine foundation repair addresses structural settling, sinking, cracking, or collapse of foundations exposed to marine or waterway conditions. This includes: timber pile foundations for docks and boathouses that have rotted at the waterline; concrete foundations on waterfront lots that have settled due to soil washout; seawall deadman anchor blocks that have lost bearing capacity; and helical pier anchor systems that need repair or augmentation. Marine foundation repair requires specialized equipment, materials rated for saltwater exposure, and knowledge of coastal construction codes.
We assess the foundation system from above and below water, identifying failed piles, undermined footings, corroded anchor hardware, and soil voids beneath the structure.
Timber piles are hammer-tested and probed to determine remaining structural capacity. Corroded steel hardware is evaluated for remaining section loss.
A licensed engineer determines whether failed components require in-place repair, sister pile installation, or underpinning with helical piers driven to stable bearing soil.
Where foundation settlement has occurred due to soft soil or soil loss, helical piers are hydraulically driven to stable bearing capacity and connected to the structure with engineered steel brackets.
Voids beneath waterfront slabs, footings, or under dock decking are filled with NCFI polyurethane foam to restore sub-surface support.
Timber piles damaged at the splash zone can be repaired with fiberglass-reinforced composite wraps that encapsulate the deteriorated section and restore structural continuity.
Marine foundation repair costs depend heavily on the repair type and scope. Helical pier installation runs $700–$2,000 per pier; polyurethane void fill under structures costs $8–$25 per board foot. Most residential marine foundation repairs run $5,000–$25,000 depending on extent.
