Gravel used for erosion control comes from mines and quarries. Its round-edged, interlocking configuration makes it the ideal rock type for allowing a natural stream of water, nutrients, and root systems to move through the soil unobstructed.Įngineers and landscapers tasked with using this type of stone on a sloped property may also use cobblestone as a filler material for a structure called a “gabion.” These are baskets or crib-like arrangements used in retaining walls or dams which allow the soil to breathe but constrict potential soil dislodging or movement. You may think cobblestone exists to make driveways and streets more aesthetically pleasing, but this type of stone has its use in erosion control. Your choice of the right rock type for your property depends on its physical orientation, and there are multiple options, each with a specific purpose. If you need to bring your soil’s fertility levels back up, erosion control blankets are a better choice. Keep in mind that using rocks as a solution for erosion control on slopes works best when your vegetation is already well-established and your soil nutrient levels are thriving. Strategic rock placement can help you maintain the positive, restorative effects of other erosion control methods by keeping soil protected from events like flash floods, high winds, and harsh, extreme sunlight. Keep reading to learn how to place rocks on a slope to stop erosion.

In these cases, rocks provide the best natural solution because you’re keeping well-established soil from draining or being blown away. Gravity isn’t doing you any favors - and harsh summer months with sudden rainfalls can drain soils of their nutrients and strangle plant life. Rock use and placement is a particularly innovative solution because it allows homeowners to blend function and aesthetics.Įrosion control is especially crucial if your home sits on a slope or your property area is hilly. Zoom in from this global picture to your slice of the land: There are a range of erosion control methods you can implement in your backyard and on your property. Soils store more than 4,000 billion tonnes of carbon, which means it’s a viable solution for reducing global carbon woes. When we lose 24 billion tonnes of fertile soil every year due to erosion, we also lose the opportunity for soils to feature as a prominent climate change solution.
