Abstract
A silt fence system employs silt fencing that is supported along the fence length with stakes. The stakes have a polymer or plastic outer casing, and either a flexible core or a core segment of rigid material such as cement. The outer casing provides resistance to the elements and the flexible material provides the give to handle hydraulic forces with breaking of the stake, as is the case when wooden stakes are used. The system employs the rigid core stakes in situations where hydraulic forces are large enough that the combination of the plastic outer casing and flexible core is insufficient to maintain stake position.
Claims16
In a silt fence system comprising a fabric material and a plurality of stakes, wherein the fabric material is secured to the stakes to define an erosion control barrier at a construction site, the improvement comprising each stake having a core of a flexible material and an outer casing of a plastic or polymeric material.
A method of installing a silt fence at a construction site comprising:
- a) providing a silt fence fabric material, and a plurality of fence stakes, each fence stake further comprising a core of a flexible material and an outer casing of a plastic or polymeric material;
- b) inserting at least a portion of each stake into the ground, the stakes in spaced apart intervals defining an erosion barrier line;
- and
- c) attaching the silt fence fabric material to the stakes.
In a silt fence system comprising a fabric material and a plurality of stakes, wherein the fabric material is secured to the stakes to define an erosion control barrier at a construction site, the improvement comprising each stake having a core segment of at least a cement or cement-like material and an outer casing of a plastic or polymeric material.
