Shoreline Erosion & Retaining Walls
Fluctuations in water levels, waves and harsh Ontario winters are just a few of the things that can impact your shoreline and result in erosion. If you are experiencing challenging slopes or erosion on your property, we can help. Kehoe will do a full assessment to determine the best course of action for limiting erosion of your waterfront property.
Retaining Walls
Retaining walls can look great and are sometimes installed just to improve waterfront esthetics but they can also provide critical shoreline stabilization and prevent erosion. Kehoe will design and install retaining walls, constructed with sheet piling, concrete, rip rap or natural stone.
A site visit is required to determine the appropriate type of material and size to adequately protect the shore from wave and ice action. Regardless of which shoreline erosion measure you select, please be aware that the time needed for approvals can be significant.

Rip Rap
Rip rap is a permanent layer of stone which is sized appropriately for the site wave climate, generally placed at a 3:1 slope with geotextile cloth separating the native soil behind the wall. These walls are used to protect the soil surface against erosion. Rip rap is an ideal solution for dissipating incoming wave energy. -
Armour Stone
Armour stone is a very durable and esthetically pleasing option used to fight against erosion. These rectangular blocks of natural rock may be placed in multiple stepped back layered levels to accommodate different shore heights. Armour stones can be stacked vertically to minimize the amount of ground space used, which offers significant benefits in developed spaces. -
Sheet Pile
Sheet pile is commonly used to encapsulate existing eroding structures. To stop erosion, an interlocking vertical steel wall system is constructed with varying profile and thicknesses of steel. Material profile and design are based on water depth, retained soil heights and required lifespan.
