Today’s steel docks are long-lasting, low-maintenance, & green

It’s a common problem on the lakes of Muskoka. You have a classic old boathouse from the golden days – well-maintained, beautifully trimmed, luxurious inside – but it’s sitting on a rotting dock. Because the underwater timbers are compressing, the doors and windows no longer open and close and the building’s structural soundness is in jeopardy.

Or you may have a vintage wooden crib dock that is inevitably losing its battle against time, nature, and water, and repairing it yet again is starting to seem pointless.

Steel docks for a strong foundation 
Worrying about dock deterioration can become a thing of the past, according to Arnie Coulson, co-owner of Coulson Brothers Scow Service, a company that offers consultation, design, and installation of steel docks, along with other services, and specializes in servicing and developing water-access properties.
“Steel docks have become the industry standard now,” Arnie explains. “You don’t get rotting, shrinking, or shifting. The piles are either driven or pinned to the bedrock and the dock stays as level and stable as the foundation of your cottage.”
Even if you have a thick layer of silt over the bedrock on your lake bottom, a steel dock can still be supported on a solid footing, through the use of helical pile technology. With the Coulsons’ specialized equipment, this torque-driven dock piling system drills each steel pile into the lake bottom. “It acts like an augur,” explains Arnie, “and with sufficient soil cohesion, it provides a firm, solid footing.” This process can represent a financial saving, with less steel and concrete needed for the piles.

A friendly footprint
The stability, durability, and longevity of steel docks are not their only advantages. As well as being virtually maintenance-free, they are also environmentally friendly. “It’s hard to get a permit for crib docks now,” says Arnie, “because their larger footprint disrupts the fish habitat and water flow.”Steel piles create a much smaller impact on the lake bottom than a crib dock of equal size.

Docks play a leading role in the enjoyment of time at the cottage, and apprehension about their condition and upkeep is unwarranted. “We consult on dock locations, get approvals, install, and can even jack up a boathouse to replace the dock underneath it,” says Arnie. With good planning, the cottage dock can fulfill its proper function – a place to relax on a sunny afternoon, dock the boat, take off on water skis, and gaze out at the priceless view of the lake.
