Henderson Marine Construction

Marine Construction

We offer end‑to‑end civil marine construction and heavy civil dredging for marinas, harbours, ship slips, ferry terminals, and industrial waterfronts. This includes self‑performing steel sheet piling (bulkheads, quay walls, cofferdams, tie‑backs), pile‑supported wharves/piers/berths, stationary and floating docks with steel frames and concrete/composite/wood decking, gangways and fendering, armour‑stone revetments, jetties/breakwaters, utility crossings, inspections, and emergency repairs, safely mobilized from our own sectional barges and floating plant.

Heavy Civil Dredging

Our dredging teams keep waterways open, accessible, and safe using state‑of‑the‑art equipment and environmentally responsible practices. These include pre‑dredge bathymetric surveys and sediment sampling with advanced sonar/GPS, mechanical dredging (clamshell/bucket) for dense material, rock removal with hydraulic hoe‑rams and mechanical recovery, and precision environmental dredging to minimize turbidity.

Erosion & Sediment Control

We manage sediments end‑to‑end approved open water placement for clean material or upland reuse/storage while handling contaminated sediments with specialized methods, certified disposal facilities, rigorous water quality monitoring, and full compliance with local, provincial, and federal regulations.

Modular Barge Rentals & Sales

We rent and sell 100% Canadian‑made modular barges. These flexible, customizable Henderson sections are available in 10′×20′ (5′ deep, ~12,500 lb), 10′×40′ (5′ deep, ~24,500 lb), and 10′ rake (5′ deep, ~6,800 lb) to support crane platforms, material handling, and remote access.
