Quick summary: Construction sites face erosion from rain, wind, and runoff, and the right control system depends on the severity and type of exposure. This guide covers 14 proven erosion control systems — from soil nails and geotextile walls to sediment basins and concrete canvas — to help you match the right method to your site conditions.
Erosion control systems help prevent soil loss and stabilise construction sites exposed to rain, wind, and surface runoff. Common solutions include erosion control blankets, geotextiles, drainage systems, sediment barriers, and vegetation, which protect soil surfaces, manage water flow, and maintain site stability during and after construction.
Erosion is one of the biggest challenges faced by many construction companies. Multiple factors cause erosion and each scenario calls for stringent control measures. The severity of the erosion will determine the type of erosion control system to implement.
Adopting an erosion control system helps protect new structures, save costs, minimize the environmental impact, and ultimately save lives. This post highlights fourteen types of erosion control systems at sites.
Before we delve further, let us consider what an erosion control system is. An erosion control system is put in place to prevent the causative agents of erosion i.e., water, wind, or sediment. An erosion control system is built with durable materials that withstand harsh conditions.
When installed with expert precision, an erosion control system can mitigate water pollution, protect underground pipelines, protect properties, and manage stormwater runoff. Some erosion control systems are installed temporarily, while others are implemented permanently.
The former reduces the risk of erosion while the latter protects the area from erosion in the long term.
Now, let us consider the types of erosion control systems available.
Soil nails are driven into the soil to create a resisting force against slope failures. They create a barrier similar to retaining walls and offer quick installation. The nails are drilled deep into the earth while capping it at the surface during the installation.
A grassed waterway is a natural or constructed channel designed to convey runoff from areas where erosion control is needed. This method of controlling erosion helps to protect water quality since the runoff filters sediment and nutrients.
These revetment systems are used to control erosion on embankments of waterways and artificial drainage channels. Articulated concrete blocks can be constructed in various shapes and thicknesses, forming a grid of interconnected units.
Shotcrete involves spraying concrete at a high speed until it reaches a certain density level or compaction. Shotcrete is more economical than most erosion control systems, yet, it is recommended to be sprayed by a professional.
Turbidity barriers are floating geotextile fabric curtains used in water bodies to contain suspended sediment and prevent it from spreading during construction, and are sometimes paired with supplemental sediment control measures.
Geotextile installation is a popular erosion control and soil improvement solution. They are used for separation, drainage, sealing, protection, filtration, and reinforcement.
A French drain uses drain tile, a system of underground piping that channels ground and surface water to an exit point. French drains are installed with a slope of approximately 1 inch of drop for every 10 feet of horizontal run.
Fabric-formed concrete is a cost-effective and high-quality solution to erosion control. It is designed by pumping highly fluid concrete into woven fabric “forms”.
This specially woven-fabric technology looks like cable-reinforced mattress sections with patterns customized to resist some of the most erosive forces.
As the name implies, this involves planting vegetation in areas with existing or potential high erosion rates. This practice is mainly adopted on sites that cannot be stabilized by standard conservation treatment.
Grouted riprap is a cement-adhesive mixture used to protect soil from erosion of riverbeds and lakeshores. Riprap comprises a layer of large stones interlocked together to serve as a barrier on unstable slopes.
It is commonly installed over a synthetic geotextile membrane to prevent erosion undercutting along ditches, channels, seawalls, and shoreline banks.
MSE walls are easy to use and offer faster installation than traditional reinforced concrete walls. Engineers use this system to control erosion in a variety of sites.
Sediment basins are installed to protect the natural resources until vegetation or structures are installed to control the source of sediment. In this practice, a constructed basin is designed to collect and store waterborne debris or sediment.
Dust control measure is ideal for construction sites affected by wind and water pollution. Polymer additives, silt fences, and misted water are standard dust control methods.
Concrete canvas ranks among the newest and fast-to-install erosion control methods. It is a flexible, concrete-filled geosynthetic material that hardens to form thin layers when hydrated. Concrete canvas needs to be installed and hydrated correctly to ensure maximum protection.
Choosing the right erosion control system depends on your site’s specific conditions — slope severity, water exposure, soil type, and whether protection needs to be temporary or permanent. From structural solutions like soil nails and MSE walls to material-based methods like geotextiles, riprap, and concrete canvas, each system addresses a different erosion challenge.
In many cases, combining two or more of these methods — such as pairing geotextile installation with vegetation, or riprap with a synthetic geotextile membrane — provides the most reliable long-term protection for construction sites.
Soil nails and MSE (Mechanically Stabilized Earth) walls are commonly used for steep slopes, since they create a resisting force against slope failure with relatively fast installation compared to traditional reinforced concrete walls.
Temporary systems, such as silt fences or sediment basins, reduce erosion risk during active construction. Permanent systems, such as MSE walls, grouted riprap, or geotextile walls, protect the area from erosion over the long term after construction is complete.
Can erosion control methods be combined?
Yes. Combining methods — such as pairing geotextile installation with vegetation, or riprap with a synthetic geotextile membrane — is common practice and generally provides more reliable protection than relying on a single method alone.
