Floating Dock Oceanside NY

Floating Docks

Floating docks, gangways, and platforms provide additions to traditional structures allowing for easy access to boats and personal watercrafts in shallow and deep water, or even no water. Floats are custom-built in any shape or configuration — square, rectangular, L & U shaped, and more. Various materials can be used including various woods, composite lumber, and plastic materials. These structures can be removed during winter months and in advance of extreme weather conditions to ensure their protection.

Helical Piles

Helical Piles

Helical piles are among the strongest and sturdiest foundation support systems available for marine construction projects. They are able to support over 50 tons in compression and tension while resisting upward force. The unique cylindrical design make helical piles easy to install without a need for heavy overhead machinery. They can be installed areas with limited access where other types of support structures may not be possible. Kevel Marine has installed thousands of helical piles in support of house-lifts and new-construction projects throughout the south shore areas of Long Island following Super-Storm Sandy.

Pile Driving

Driven Piles

Kevel Marine can drive deep piling foundation-work for structures located nearby bayfronts, waterways or above high-water tables. We use strong poles driven deep into the ground to create stilts which force surrounding earth materials to close around the pile lock it into place. A critical step in foundation construction, these piles become part of the structure’s primary foundation. We more than 25 years of experience installing piles made of timber, steel, concrete and sheet, and offer sturdy and long-lasting solutions. In addition to pile construction, we also offer complete repair services to preserve the integrity of your marine structures.

Crane Service Hewlett NY

Crane Services

Avoid exposure to ice and harsh weather conditions by scheduling a haul-out for your boat, floating dock and gangway ahead of the winter months. Our crane gently lifts your vessel and dock materials to store them on your property and return them to the water in the spring.

Boat Lifts

Boatlifts and bulkhead elevators keep your boat safe in busy areas and rough weather conditions. They significantly reduce vessel maintenance by eliminating marine growth such as barnacles and algae. Boat lifts can also reduce or eliminate winter storage costs. Kevel Marine sells and install boatlifts from top companies such as IMM® and other manufacturers. We can help you determine the proper type and size of lift for your yacht, boat, jet-ski and other watercraft. We also provide boatlift maintenance services too.
