Wire Backed Silt Fence

Product Overview

Our wire backed silt fences are available in black or orange, supplied in a convenient 4 ft x 100 ft roll. Each roll contains pre‑attached woven polypropylene fabric bonded to a galvanized wire mesh, providing superior strength and erosion control on demanding job sites where standard silt fences cannot withstand the flow. The UV‑stabilized fabric and rust‑resistant wire ensure a service life of 1–2 years under typical construction conditions, making this product a reliable choice for DOT‑compliant projects, steep slopes, and high‑flow channels.

Technical Specifications

Specs

Colors: Available in Orange or Black – choose according to site visibility requirements or local regulations.

Material: Heavy‑duty woven polypropylene fabric that resists tearing and UV degradation for extended outdoor use.

Dimensions: 4 ft x 100 ft Roll – covers 400 square feet of perimeter, ideal for medium‑sized construction sites.

Roll Length: 100 ft Length – continuous fabric ensures fewer seams and faster installation.

Fabric Width: 4 ft – standard width accepted by most silt fence installer machines and trenching equipment.

Welded Wire Width: 3 ft – 14‑gauge electro‑galvanized wire provides a sturdy backbone while allowing the fabric to extend for proper trenching.

Wire Mesh Opening: 2 inch by 4 inch – our tighter 2x4 inch openings deliver 50% more wire coverage than the industry standard 4x4 inch mesh, reducing the risk of fence collapse under heavy sediment loads.

UV Stabilized – fabric is treated to resist degradation from sunlight, maintaining tensile strength and filtering performance for up to two years.

DOT Compliant – meets or exceeds state Department of Transportation specifications for silt fencing, ensuring approval on regulated road and bridge projects.

Gauge: 14 Gauge – provides the ideal balance of rigidity and flexibility for easy handling and long‑term stability.

Rust Resistant: Electro Galvanized – the wire is coated with a sacrificial zinc layer that prevents rust even in moist, chloride‑rich environments common on excavation sites.

Key Features & Benefits

Features

Meets or exceeds DOT Specs: Our Wire Back Silt Fence meets or exceeds DOT specifications for silt fencing. Wire backed silt fences are required on the toughest job sites, where standard silt fences are not sufficient to prevent silt from leaving your site and entering nearby stormwater drainage systems. This product has been tested for flow‑through and sediment capture efficiency, giving you confidence in regulatory compliance.

Lasts 1–2 Years (Depending on Site Conditions) – the combination of UV‑stabilized polypropylene and galvanized steel wire provides a service life that is typically twice that of standard silt fences, reducing replacement labor and material costs over the project duration.

Added Wire Mesh For A More Stable Fence: Sandbaggy rolls provide 50% more wire mesh than our competitors! That’s because our wire mesh openings are 2" x 4", while our competitor's is 4" x 4". The more wire mesh, the less likely your fence will collapse. This tighter spacing also distributes hydrostatic pressure more evenly, preventing bulging and blowouts during heavy rain events.

Pre‑attached fabric: Silt Fence Fabric is pre‑attached to the wire mesh prior to shipping. Once you receive the roll(s), you just unroll and trench fabric into ground. This one‑piece design eliminates the need for on‑site assembly, saving valuable labor hours and ensuring consistent overlap.

Compatible with Silt Fence Installer Machines: Engineered for easy installation with silt fence installer machines, such as Blue Diamond Silt Fence Installer Attachment. The consistent roll width and uniform wire attachment reduce jamming and downtime, making this an efficient choice for large‑scale projects.

Applications & Heavy‑Duty Use Cases

APPLICATION

Galvanized 14 gauge wire (Rust Proof): Using electro‑galvanized 14‑gauge wire, Sandbaggy Wire Back Silt Fence is built to last for 1–2 yrs on a job site. The zinc coating protects against corrosion from soil moisture and road salts, maintaining structural integrity throughout the project lifecycle.

UV stabilized fabric: Sandbaggy Fabric is UV Stabilized to allow for extended use on construction sites. Without UV inhibitors, polypropylene can lose strength in as little as three months; our treatment ensures the fabric remains effective for the entire warranty period.

Heavy Duty Use – Reinforced Silt Fences have more stability than regular silt fences. Use these silt fences for erosion control on:

Construction Sites – where earth‑disturbing activities generate high volumes of runoff laden with fine sediment. Our fence captures particles as small as 0.2 mm, protecting downstream waterways.

Steep Slopes – on grades exceeding 3:1, standard fences often fail due to hydrostatic pressure. The wire backing provides the extra tensile strength needed to hold the fabric against the slope and channel water safely to sediment basins.

High Flow Areas – in channels, ditches, and culvert outlets where water velocity can exceed 2 ft/s. The reinforced wire mesh prevents the fence from being undermined or torn away, maintaining continuous sediment control.

Windy Areas – the added weight of the wire mesh reduces wind‑induced flutter, keeping the fence upright and in contact with the ground, even during gusty conditions common on open lots and plains.
