When it comes to burying the lower edge of the filter cloth, it’s recommended to bury it to a minimum depth of 6 inches. This ensures that the silt fence is securely anchored in the ground and can effectively prevent sediment from flowing through. The cloth should be carefully compacted into place to create a barrier that can intercept sediment-laden water.
The amount of cloth that needs to be buried depends on the height and length of the silt fence. A standard roll of silt fence typically measures around 3 to 4 feet in height and can be anywhere from 50 to 100 feet long. It’s important to calculate the required length of silt fence beforehand to determine the amount of cloth that will be needed.
This can be done by taking measurements of the designated area, including any curves or corners. It’s recommended to add an additional 10% to the calculated length to account for any overlapping of the cloth during installation.
This can be done by considering the standard roll size and dividing the length of silt fence needed by the length of cloth in each roll. It’s always better to have an extra roll or two on hand to account for any unexpected changes or repairs that may be needed.
Following established guidelines and investing in sufficient cloth can help achieve optimal results and prevent erosion and sedimentation issues.
