Canady’s Erosion handles any project where preserving the soil or shoreline is a priority. We’ve handled projects ranging from small private construction contracts to large and complex government needs. Some of our past projects include:
- Waste Water Treatment Plants
- Solar Farms
- Athletic Fields
- Commercial Projects
- Industrial Projects
We stay on the cutting edge of erosion control methods, always striving to adopt the best techniques or combination of techniques for each individual situation. We invite you to learn more about some of these techniques below.
Hand sowing (or planting) is the process of casting handfuls of seed over prepared ground. It is also called “broadcasting” (from which the technological term is derived). Usually, a drag or harrow is employed to incorporate the seed into the soil. Though labor-intensive for any but small areas, we still use this method in some situations. Practice is required to sow evenly and at the desired rate. A hand seeder can be used for sowing, though it is usually reserved for small seeds, such as those of grasses and legumes.
Also known as hydraulic mulch seeding or hydro-mulching, hydroseeding is a planting process which utilizes a slurry of seed and mulch. The slurry is transported in a truck- or trailer-mounted tank and sprayed over prepared ground. Helicopters have been used to cover larger areas. Aircraft application may also be used on burned wilderness areas after a fire, and in such uses may contain only soil stabilizer to avoid introducing non-native plant species. Hydroseeding is an alternative to the traditional process of broadcasting or sowing dry seed. The slurry often has other ingredients including fertilizer, tackifying agents, green dye and other additives.
Sometimes (misleadingly) called a “filter fence,” a silt fence is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff. Silt fences are widely used on construction sites due to their low cost and simple design, although their effectiveness in controlling sediment is often rather limited, due to problems with design, installation and/or maintenance.
A coir fiber baffle is a porous barrier installed in sediment dams and silt basins. The baffles reduce the velocity of the runoff into the erosion control device, which facilitates the settling of sediment before being discharged offsite. The baffle consists of a coir fiber mat supported by the same steel T-posts that are used for temporary silt fences. Baffles help prevent short-circuiting of flows through the device to the outlet point with little or no settling time. In addition, the baffles improve sediment retention because they distribute the flow, which reduces turbulence of the runoff inside the device.
Waddles are long logs made of biodegradable fabric filled with straw or wood chips. Like the silt fences they sometimes replace, they help trap sediment, slow the water flow rate, and break up slopes into more manageable lengths to protect water quality and vegetation further down the slope. Waddles also have the advantage of being 100% environmentally-friendly and can be left in place to biodegrade after they’ve served their purpose.
Erosion control mats are used to temporarily stabilize and protect disturbed soil from raindrop impact and surface erosion, to increase infiltration, decrease compaction and soil crusting, and to conserve soil moisture. Mulching with erosion control blankets will increase the germination rates for grasses and legumes and promote vegetation establishment. Erosion control mats also protect seeds from predators, and reduce desiccation and evaporation by insulating the soil and seed environment.
During construction, dirt, clay, sediment-filled runoff, and other pollutants can pour down wastewater inlets, greatly increasing the contamination of the water and the burden on the wastewater plant. Sometimes, this water is diverted to the overflow channels for rainwater and gets poured into retention ponds or streams, causing ecological problems as well. To prevent these and other crises, inlet protection methods introduce filters on, around, or within public wastewater inlets, such as sewage grates.
Block & Stone
Large stones (riprap) are a popular and effective method of preventing erosion near water outlets, such as where pipes or diversion channels empty into streams, rivers, or lakes. Stone inlets help slow the erosion of the bank, reduce the velocity of the incoming water, and act as a barrier for silt, sand, and dirt, which may contaminate the runoff water during heavy rains. Large wire cages filled with blocks or stones are also effective methods for stabilizing steep slopes, especially near water sources.
