Services / Shoreline and Revetment Work
Shoreline and Revetment Work
Stone placed at the water line to stop a shoreline eroding. Armour stone walls where the bank needs to stand upright, rip rap revetments where it can slope.
Waves, ice and changing water levels pull material out of an unprotected bank a little at a time. Stone at the water line takes that energy instead of the soil behind it.
A shoreline wall stacks armour stone into a near-vertical face. A revetment lays rip rap or armour stone on a slope. Which suits a site depends on the bank, the exposure and what the approvals allow.
What We Provide
- Armour stone and rip rap sized for the exposure
- Delivery to waterfront sites, staged where the truck can reach
- Placement of the stone by machine from the bank
- Shoreline walls and sloped stone revetments
Site and Access
- Access from the road to the shoreline for a loaded truck
- Slope and ground conditions between the unloading point and the water
- Docks, boathouses and neighbouring shoreline
- Water level at the time of work
Base and Drainage
Stone on a shoreline is normally built over a filter layer so the bank behind it cannot wash out through the gaps, with the bottom row set into the bed. Work at or below the water line in Ontario usually needs approval before it starts, often from the local conservation authority, and in-water work can be limited to certain times of year. Approvals should be in place before any stone is ordered.
Equipment
Waterfront sites usually need a machine with enough reach to place stone at the water line from the bank, and stone brought in where a loaded truck can safely turn and unload.
What Drives the Price
Every job is quoted on site conditions, so no price is published here. These are the things that move it:
- Length of shoreline and height of the bank
- Size of stone the exposure calls for
- Wall or sloped revetment
- Access from the road to the water
- Approvals and the time of year
- Delivery distance
