Demex Construction Services

As a family-owned business, we have been serving the coastal shoreline from Port Buffalo to Port Monroe for over a decade. Our sister companies, Demex Marine Construction and Gamellia Ironworks & Construction, specialize in the core elements of marine construction, focusing on erosion prevention, construction, and maintenance. We are dedicated to providing exceptional services, such as Revetments & Seawalls, Cribs, Piers, & Docks, Pile Driving, and Dredging, to enhance your water access and protect your property from erosion.

Our History

Our journey began in 2006 when Jim Gamellia Jr. started Gamellia Ironworks and Glassblowing, later to become Gamellia Ironworks and Construction. Over the years, we have evolved and shifted our focus to Specialty Marine Contracting, leading us to where we are today. With three generations of the Gamellia family involved in the business, we are committed to preserving the values of true craftsmanship, safety, and environmental responsibility.

Our Services

Our services are designed to meet the needs of both residential and civil projects. We believe in using locally sourced materials and American-made steel on every project, ensuring our connection to the local economy. Our team of highly trained crews and meticulously maintained fleet guarantee that we can handle any project efficiently and safely.

Revetments & Seawalls

Revetments are a great option to drastically slow the effects of erosion due to wave action. From a few feet to miles of armor stone, we can provide solutions tailored to your specific needs and property requirements.

Cribs, Piers, & Docks

We offer a variety of options to enhance your water access on your property, including ballast stone-filled cribs, timber docks leading to the water, and other solutions designed to meet your unique needs.

Pile Driving

Sometimes, there is just no substitute for the power of steel. Sheet piling installations are a tall order, but they will secure the shores of your property. Our experienced team is equipped to handle any pile driving project, no matter the size or complexity.

Dredging

When marinas and boat launches get a little too shallow, it's time to dredge. We are ready to ensure you get back to a safe water depth with our state-of-the-art equipment and expert crews.

Additional Services

In addition to our core services, we also provide Underground Utilities, Site Restoration, Excavation, and Site Work. Our commitment to providing comprehensive solutions sets us apart from other marine construction companies.

Safety and Health

At Demex Marine Construction and Gamellia Ironworks & Construction, we prioritize safety and health above all else. Our rigorous safety training and "human aspect" core management philosophy ensure that we complete every project without incident. We believe in protecting both our area's greatest natural resource, Lake Erie, and the shores that surround her.

In the Community

We are proud to be part of the local community and believe in giving back. Through our work, we aim to preserve the beauty and integrity of Lake Erie and its surrounding shores for future generations.
