Silt Control

Silt control is the practice of managing silt and sentiment on construction sites to ensure it does not migrate into nearby watercourses and pollute them. Stratec offers a range of products designed to fit any requirement, including Silt Fencing, Sediment Mats and Sandbags.

Sediment Mats / Sandbags

Sediment mats, also known as silt mats, are used in waterways during construction activities. They are used to trap disturbed sediment and silt that migrate into steams and watercourses that could pollute aquatic habitats downstream.

Sediment mats are biodegradable and fixed to the stream bed, in order to filter the water and trap debris without impeding water flow.

Sandbags are another method of silt control in streams and watercourses. They work by diverting the flow of water away from a certain area, this also makes them efficient in erosion control. Sandbags can also be used to isolate an area for work.

Sandbags allow for a high flow of water to pass while effectively filtering out the sediment and in turn preventing pollution. Sandbags are great for reinforcing existing structures and flood reduction measures.

Both Sediment mats and sandbags are effective tools for the protection of streams from pollution and are often used in conjunction with other silt control measures such as silt fencing.

Silt Fencing

Silt fencing, also known as Silt Stop, is a temporary barrier intended for retaining sediment and preventing pollution on construction sites. There are several laws and guidelines governing pollution that must be adhered to.

They are made of synthetic filtration fabric, usually, geotextile filter fabric, woven together to create sheets of material that are extremely strong yet water permeable. They are often used in conjunction with bulk bags and prefilled sandbags.

They are designed to provide temporary protection to rivers, lakes, and streams by preventing loose soil or silt from migrating into the water and polluting it.

Once the ground is no longer being disturbed by activities such as construction and revegetation and permanent soil stabilisation has begun, then the silt fencing can be removed.

Pegs and pins are used in a number of applications in order to secure materials. They are usually timber stakes that are left in the installation permanently to keep it in place. They are commonly used to support Silt Fencing, Erosion Control Blankets and Geocell.
