Super Silt Fencing Calculator

To get started, just enter the length of the super silt fencing you require.

According to the GD05 Erosion and Sediment Control Guidelines, silt fence posts are generally spaced between 2 and 4 metres apart. Our calculator uses an average spacing of 3 metres to give an approximate quantity for estimating only.

Please note that some products are supplied in fixed box quantities and can’t be split into smaller amounts.
