GeoFilter GN Filter Fabric --- is a Non-Woven fabric made from high quality polypropylene fibers &#; bonded and needle punched to form a strong fabric that retains its dimensional stability and is resistant to damage from construction stresses
The most effective solution is to stop the erosion before it starts
That's where GeoFilter GN Geotextile Fabric can be very helpful
Filter fabrics allow water to flow through while filtering out substances like sediment, silt, and dirt, and they are typically used in the construction process during drainage processes. Nonwoven Filter fabrics typically consist of needle-thin pores that help with effective filtration and help with controlling erosion with moderate strength while woven monofilament filter fabrics are woven fabrics with lower water flow rates but higher strength relative to their weight.
Filter fabrics come in lightweight, heavy duty, or even medium heavy versions. This allows a higher amount of control and choice when choosing a filter fabric for applications such as pipes, French drains, retaining wall drainage zones and driveway, parking lot, and laydown yard underlayment.
Filter fabrics can provide a large variety of benefits as different types of geosynthetic filter fabrics provide varying levels of support when it comes to separation, drainage, and stabilization. It is important to look at what you are trying to achieve in your application to determine which type and strength of fabric best meets your requirements.

Geo textile filter fabrics can be utilized in a number of ways. Below are some of the most common applications for our nonwoven geotextile fabrics:
Most construction projects involve the removal, addition, or manipulation of dirt. In the weeks, months, or years that such projects require to be completed, loose soil spreads outside of the construction zones, causing loose dirt to muddy up nearby sources of water.
As a means of maintaining water quality, many builders erect silt fences around their building sites' borders. These are constructed of non woven geotextile fabrics and fence posts. Silt fences are good for keeping dirt and debris out of nearby streams, rivers, lakes, and ponds as long as these silt fences are placed in good locations, maintained properly, and installed properly.
Drains are used to keep water out of areas that have been shown to pool or otherwise retain more water than surrounding areas. One of the most popular types of modern drains is the French drain.
To dig a French drain, you&#;ll first dig a trench that is very slightly sloped. A plastic drain is placed in the bottom, which is then surrounded by rocks and covered by non woven geotextile fabric. Dirt is placed on top of the fabric. The fabric helps keep dirt out of the drain, preventing it from getting clogged and causing soil erosion.
Over time, the shoreline of beaches changes. This can cause normal sea levels to get too close to existing structures.
One way to maintain shorelines is to lay down strong non woven geotextile fabric at the current shoreline. Next, tons of sand are placed on top of the fabric. This process has to be repeated every few years to keep barriers from showing.
Gabion Supply has all the non woven geotextiles you need for all your erosion control and filtration applications. Contact us today for quantity pricing and product availability.
What's the Best Landscape Fabric for Draining Water?
Not all Landscape Fabrics function the same way, so be sure to use Non-woven geotextile for proper drainage
On the surface, there seems to be little difference between woven and non-woven geotextile landscape fabrics. Both are designed to increase soil stabilization and ground support. However, depending on what surface you have and what your goals are, choosing the right landscape fabric for drainage makes all the difference to the outcome of your project.
Non-woven geotextile fabric is the best choice for drainage applications where water flow through (permeability) is the main concern. Non-woven landscape fabric is commonly used in French-drains, drain-fields, and erosion control.
There are only two primary types of fabrics used in landscape, and construction applications; woven geotextile, and non-woven geotextile fabric. Read on to discover which one is more suitable for your application.

Geotextile Landscape Fabrics: Non-Woven VS. Woven
Woven Geotextiles are strong, finely spun strips of linen, polypropylene, or polyester material. It is typically impermeable, and water drainage through the material is minimal.
This geotextile&#;s durability (pull strength) and warp resistance is ideal beneath high load capacity surfaces, including gravel/rock footpaths, highways, and parking lots.
Common Non-Woven Fabric Applications
Water flow (permeability)
Xeriscaping
Filtration
Common Woven Fabric Strengths:
As a weed barrier
Beneath roads/paths
Parking lots
Nonwoven fabric in French Drain
Woven fabric layer under driveway
Below are the benefits of woven and non-woven geotextile products to help you make an informed decision.
Non-Woven geotextile fabric explained
Needle-punched and poly-spun varieties of non-woven geotextile fabric allow water to easily flow through and are both sturdy and versatile for landscaping drainage. The non-woven geotextile fabric is most commonly used as a landscape material to support adequate drainage, filtration, and ground stabilization.
Available as lightweight, medium weight, and heavy weight, these fabrics feel like felt to the touch.
Fabric Weight Categories:
Light weight (2 oz. to 3 oz.)
High flow rates, substrate cushioning, and drain-field type applications. The 3 oz weight is often used behind retaining walls to act as a barrier between the dirt and gravel.
Medium weight (4 oz. to 6 oz.)
A medium weight non-woven fabrics allows water penetration without displacing existing soils. It also helps in controlling soil erosion, separation and drainage functions (French-drains). Additionally we see these weighted fabrics utilized beneath gravel paths acting as a separation barrier between the gravel and the dirt below.

Heavy weight (8 oz. to 16 oz.)
Heavy weight non-woven fabrics are great for applications requiring strength and permeability. They are more resistant to puncturing and their durability makes them a good choice underneath large rip-rap, geomembrane cushioning when applied to retention barriers and artificial lakes. Please note that toward the upper end of the weight spectrum (10 oz +) the water flow rate diminishes significantly due to the thickness of the material.
Heavy non-wovens are also used as a separation layer for sand under volleyball courts (8 oz), and to prevent the mixing of ballast and soil under railroad tracks (16 oz).
Note: If you are installing artificial turf, or pavers we have a Drainage mat roll available in multiple sizes and types.
PRO TIP:
For a french drain application, 4 oz fabric is most commonly used. This fabric provides a nice mix of durability and high water water flow rates.

Woven Geotextile Fabric Explained
Woven Geotextiles also called driveway matting are processed by pressing and cutting polypropylene layers and then weaving them into high tensile sheets. The result is a premium filter that is resistant to foreign particle clogging from dirt, sand, or other debris.
The woven geotextile fabric can bear heavy loads, tolerate road rut, extend pavement life, and act as a significant sediment barrier.
It should be noted that this fabric&#;s low permeability is not ideal where drainage is necessary. Woven geotextile fabrics work best when a tightly wound, nonporous, uniform material is needed.
Woven geotextiles are an excellent choice for projects requiring water to flow over a subsurface.
Advantages of Woven Fabrics:
Strength and durability
Ground stabilization
Woven ground cover fabrics resist UV decay
Retains tension
Three categories of woven fabric:
Woven geotextiles are versatile and are manufactured in three varieties: slit film woven geotextiles, monofilament geotextiles, and combination woven geotextiles.
Silt Film Woven Geotextiles
Made of interlaced plastic sheets, Silt Film is used to separate and stabilize weaker soils. It is has a lower permeability than drainage fabric and can be quickly setup around a jobsite. This product is also known as silt fence and serves as a vertical barrier held in place with wooden or metal stakes to help prevents sediment from flowing downhill.
This type of fabric is also used under gravel paths and for some road construction applications.
Monofilament Geotextiles
Monofilament fabrics are typically constructed from interlaced poly fibers or tape yarns. This class of fabric is much stronger than silt film and will perform well on under heavy loads.
These fabrics are typically used for filtration projects, such as spillway areas, bulkhead applications, seawalls, and securing shorelines.
Combination Woven Geotextiles
Combination or hybrid fabrics consist of yarns woven together in alternating patterns that provide greater strength than monofilaments. The weave also enables water to flow through easily. These fabrics are most appropriately used in projects requiring strength and specific fluid mechanics.
In general these high end geotextiles are typically specified by a project engineer or called out on a plan.
PRO TIP:
Woven fabrics excel at strength, but typically suffer in drainage unless they are a high end monofilament or combination fabric.
