They are two ways to build a silt fence the right way and the wrong way. The wrong way will lead to erosion and damage. Follow our instructions below to ensure you do the job properly. Silt fences are usually built in landscaped areas and constructions sites to ensure sediment can’t enter from waterways as well as prevent erosion. It is often temporary and is a low-cost solution to separating or catching the flow of excess to waterways.
Installing a silt fence is labor intensive but can done. All you need is the correct materials and to have a clear understanding of how to do it properly. The below procedure will demonstrate how to manually install a Silt Fence using some basic landscaping resources.
What You’ll Need:
- Roll of String
- Trench digger
- Sledge Hammer
- Staple Gun and Staples
- Silt Fence
- Wooden Stakes
1) DIG THE TRENCH LINE
Using a digger, dig a six (6) inch deep and four (4) inch wide trenches along the area that needs to be protected. Your digger needs be long enough to ensure the depth is accommodated for.
2) INSTALL WOODEN SUPPORT STAKES
On the downside of the hill, drive the pointed end of the wooden stakes into the ground using the sledgehammer. Space your pegs at 1 to 1 ½ meters apart and bury them at least 15cm into the ground.
The length and diameter of your hardwood stakes will depend on your site plan specifications. But their length and depth of installation must be sufficient to meet the requirement of the project. We recommend 38 x 38mm x 0.6m for the 0.77m Silt Fence and 38 x 38mm x 0.9m or 1.05m for the 0.86m Silt Fence.
3) PLACE SILT FENCE FABRIC
Silt Fence is a woven Propylene material. It is used to prevent sediment and pollutants from entering drainage and waterways.
The Fabric needs to run along the inner side of the stakes, make sure that the fabric is as tight as possible. Dig and bury the lower quarter of the silt fence into the ditch. Use a staple gun with heavy-duty staples to fasten the fabric onto the hardwood stakes. You will need at least 3 staples to attach the fabric to the stake
4) BACKFILL TRENCH WITH SOIL
Cover over the trench with removed soil to secure its location. It is best to pile up more soil than you think is needed since it will settle over time. Compacting or backfilling must be done correctly to form a sturdy barrier. For best results, use a compactor or a flat metal square with a wooden handle and tamp all the area you just filled.
Incorrect installation of silt fence may lead to serious issues. The key is to use quality erosion control products to achieve the best results.
