Silt Fences (Filter Fence)

A silt fence, often referred to as a “filter fence,” serves as a temporary sediment control device utilized on construction sites to safeguard the water quality of nearby streams, rivers, lakes, and seas from sediment present in stormwater runoff.

Our silt fences primarily function as perimeter controls and are commonly employed in conjunction with sediment basins, sediment traps, and erosion controls. These measures aim to retain sediment in areas where the soil is disturbed due to construction activities, such as land grading and earthworks. Silt fencing, a widely adopted temporary sediment control device in construction, plays a crucial role in preventing runoff after storms and restricting loose sediment from entering waterways. Among the various sediment control methods available, silt fencing stands out for its effectiveness, rapid installation, and cost-effectiveness.

The construction of our filter fences involves utilizing high-quality filter fabric stretched between a series of wooden or metal fence stakes positioned along a horizontal contour level. Installation involves placing the stakes on the downhill side of the fence, and the lower edge of the fabric can be trenching into the soil and backfilled on the uphill side. However, relocating the trenched soil from the downside to the upside of the trench can be challenging. The design and placement of the silt fence are intended to create runoff pooling, facilitating sedimentation. Although water can permeate through the silt fence fabric, it is not uncommon for the fabric to become obstructed by fine soil particles over time.
