Revetments & Seawalls

Cribs, Piers, & Docks

From a few feet to miles of armor stone,  Revetments are a great option to drastically slow the effects of erosion due to wave action. 

From ballast stone filled cribs, to timber docks leading to the water, there are many options to enhance your water access on your property.

Pile Driving

Dredging 

Sometimes there is just no substitute for the power of steel. Sheet piling installations are a tall order, but will secure the shores of your property. 

When those marinas and boat launches get a little too shallow, it's time to dredge. We're ready to ensure you get back to a safe water depth.
