DREDGING
Dean Construction performs dredging for all levels of the Government, industrial, commercial and private owners.
Projects are performed using our fleet of Clamshell Dredges (up to 17 cubic yard buckets), as well as suction dredges. Material can be disposed of on land or in open water.
Environmentally friendly removal of under-water contaminants has been achieved using specialized equipment, procedures and monitoring. Our specialized crews are fully experienced professionals with many years of experience and training in the marine/heavy construction field.
Turbidity curtains and environmental monitoring can be supplied.
Some of our more recent dredging projects include:
•Hamilton Harbour
•Burlington Channel
•Amherstburg Coast Guard
•Oshawa Harbour
•Lower Detroit River, Amherstburg

CAPABILITIES
DEEP FOUNDATIONS
Over the past 50 years Dean Construction has driven countless piles and drilled numerous caissons in all types of ground to support buildings, bridges and heavy equipment. We have also sunk shafts and built large cofferdams in difficult soils to permit the safe construction of water and sewage treatment plants, pumping stations and the deep foundations required for many industrial projects.
Because of the volume of our deep foundation work, we maintain close contact with international suppliers of steel piling and have ready access to economical sections at discount prices.
We encourage our clients and their engineers to contact us early in the design stages of a project so we can assist them in selecting the most cost-effective design for their deep foundations. For larger projects, we can also drive and proof-load test piles to ensure that the piling costs are minimized.

Pile Driving
Rock-socketed piles as well as grouted, tensioned rock anchors have also been installed by Dean.

Caissons
Cast-in-place drilled shafts, these foundation elements provide compressive capacity using concrete and rebar. Dean has installed "belled" and "straight" versions of these for many years

Helical Piles
Helical Piles can be used to provide Deep Foundations in many situations. The portability of the equipment makes them ideal for limited access projects. (ie. between or inside structures) Installation is nearly free from vibrations, so work can be achieved on or near sensitive structures.
Dean Construction has installed units up to 30" in diameter with 6 5/8" diameter shafts up to 100' deep.

Micropiles
Dean has installed micropiles at numerous sites as a cost saving alternate to coventional deep foundations. Micropiles have also been useful where sites are inaccessible to larger equipment or where vibration must be avoided.

Recreational Marinas
Dean Construction has built recreational marinas for many public and private clients around the Great Lakes. The scope of our work typically includes the construction of breakwaters, shorewalls, dredging, boat ramps, mooring piles, fixed and / or floating docks, utilities, fueling stations and sewage pump outs.

Marine Slip
Our Marine Slips on the Detroit River are equipped with facilities to dock, store and load/off-load vessels with a maximum draft of 10'.
We are also equipped with a Marine Railway to pull vessels up to 500 tons for inspection, painting and repair.

Shoreline Protection
Dean Construction has protected many miles of shoreline from flooding and erosion with the installation of engineered systems appropriate to the location. These systems have included steel sheet piling, concrete bulkheads, armour stone revetments, steel bin walls, groyne fields and various proprietary systems. We have also helped to protect and restore environmentally sensitive wetlands, fish habitats and recreational areas through the construction of sediment traps, fish ladders, artificial reefs, spawning areas and beach sills.
Our clients include many local, regional and national agencies, both in Canada and the United States. We are therefore thoroughly familiar with the ever-changing Regulatory, Approvals and Permitting processes which apply to construction activities on the Great Lakes and within regional waterways.

Vertical Shaft Installtion
Dean performs land and marine based drilling operations through soil and stone for foundations
This includes drilling operations for large diameter foundations, as well as vertical connections to tunnels, water intakes and sewers.
Diameters of up to 14' have been achieved underwater with strict environmental protocols enforced by the concerned authorities.
Rock-socketed piles as well as grouted, tensioned rock anchors have also been installed by Dean.
