Control Sediment Movement Before It Reaches The Watercourse

Silt Fencing
Murlac Silt Fencing provides a temporary, permeable barrier for controlling sediment-laden surface run-off during groundworks and construction activity. The woven polypropylene geotextile allows water to pass through while retaining soil and sediment before it reaches drains, ditches, streams and other sensitive areas.

A Practical Barrier Between Disturbed Ground And The Watercourse


Silt fencing is installed across the expected path of surface run-off to intercept soil and sediment moving from exposed ground. The porous geotextile slows the flow and allows water to pass through, while larger suspended particles accumulate on the upstream side of the barrier.

Correct positioning is essential. The fence should follow the site contours and run across the anticipated direction of flow rather than directly down a slope. Its lower edge is buried within a compacted trench to reduce water and sediment passing beneath the fabric.

KEY PRODUCT FEATURES

Developed For Effective Site Sediment Control

Murlac Silt Fencing provides a strong, permeable barrier that helps control sediment-laden run-off across exposed sites. UV-stabilised geotextile, burial marker lines and reusable components support straightforward installation, reliable performance and flexible use as projects progress.

Permeable Sediment Barrier

Allows water to pass through while retaining soil and suspended sediment.

High-Strength Geotextile

Woven polypropylene provides a strong temporary barrier for exposed sites.

UV-Stabilised Material

Added UV protection supports continued outdoor use throughout the project.

Burial Marker Lines

Visible lines help installers position the fabric at the recommended trench depth.

Reusable & Repositionable

Serviceable sections can be adjusted or relocated as the project progresses.

Complete Kit Available

Rolls, timber posts, nails and protective washers can be supplied together.
COMMON APPLICATIONS
Where Silt Fencing Is Used

Silt fencing can be installed wherever disturbed soil may be carried across the ground towards drainage systems or sensitive water environments. The final alignment should reflect the site contours, direction of run-off and available installation area.
