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.

Dean Construction owns and operates many types of conventional equipment including diesel impact hammers, caisson drills, (to 90" diameter) and all associated equipment. We also have ready access to wide variety of specialized equipment through our contacts in the industry across North America

Pile Driving

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

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.

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

Dredging for Sterling Fuel Dock

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



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.

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.

ENVIRONMENTAL WORKS

Construction of new fish spawning/habitat areas.
Enhancement of existing marine areas through the construction of spawing beds and artificial reefs.
Construction of structures to protect natural areas from disruptive species.

Shoring / Cofferdams

Dean installs numerous earth-retention and dewatering structures every year. Whether to permit excavation and construction, or support existing structures and soild. Dean has the experience and expertise to provide economical solutions.
