Geotech Fabric



Geotech fabric (geotextile fabric or geo-fabric) can be used for a variety of applications such as french drains, drain fields, erosion control, separation and stabilization, and more. The fabric is composed from polypropylene blend and is needle punched to provide water permeability. This geotextile material is specially formulated to resist ultraviolet light deterioration and is inert to commonly encountered soil chemicals. The fabric will not rot or mildew, is non-biodegradable, and is resistant to damage from insects and rodents.

Our non-woven geotextile fabrics are available in weights ranging from a 3oz to a 16oz per square yard. The lighter the fabric options provide a higher water flow rate while the heavier the fabrics are stronger but provide a lower water flow rate.

Woven Geotextile Fabric
In addition to non-woven getoextile fabric we also provide a large selection of woven fabric which is ideal for stabilization applications.

Do These Fabrics Drain Water?

Most drainage fabrics on the market claim to be permeable with a high water flow rate. Specification sheets show flow rate but it can be difficult to translate the testing numbers into a real world example.

Frequently Asked Questions

Why Using Geotextile Landscaping Fabric For Your Next Project Is Important

For years landscape fabric has been playing a major role in most hardscape projects. This fabric is designed to separate, reinforce, and filter in order to provide good drainage and filtration. Not all fabrics are good choices for all projects, there are several differences that must be taken into consideration before choosing a fabric. Understanding the differences is important for developing a successful landscaping project.

Woven & Non-Woven Geotextile Fabric

Woven and non-woven have their own strengths and weaknesses when it comes to making a decision on what should be used in a given project. Where one might excel, the other might fail. In this article we will go over their similarities and differences and where each one should be used in a successful landscaping project.

As geotextile offers separation, filtration, reinforcement, and drainage, as mentioned, above, it's critical where subgrade materials will remain saturated for a good portion of a year or will be present during multiple freeze-thaw cycles during the winter months.

It's critical that the separation of the subgrade from the base material will stop the movement of the soil. This is an upward movement of the soil subgrade into the base material caused by the load the pavement carries. As an example, a heavy object falls in the mud, the object is the load pushing down on the mud causing it to shift upwards and horizontally.

Shifting to geotextile, the stabilization or reinforcement of the base material when using geotextile will help to spread the load out over a greater distance because the geotextile is in tension and provides tensile strength to the base material. The filtration of geotextiles will allow water to spread out over a wider area and have greater control over the drainage of the water. When choosing the right geotextile for a project, there are a few factors to take into consideration, but first, you need to know about the two kinds of geotextile and their values.

Geotech Fabric Used in Landscaping

Woven Geotextile Landscape Fabric

Woven geotextile fabric is made of polypropylene filaments connected to a network for greater stabilization and strength than non-woven geotextile. This fabric offers separation, filtration, and reinforcement strength when used.

Geotextile woven fabric is used for driveways such as heavier dynamic and static load projects to add more reinforcement to the base by spreading the load out over a greater distance. If you can't get the drainage you need from the geotextile, you need to install a drainage system for the project using perforated or solid pipes and drains in order to collect the water and withdraw it out of the system. If not taken care of, the water will create a reservoir allowing water to stand causing other issues over time.

Non-Woven Geotextile Landscape Fabric

Made of polypropylene fibers, the fibers in the non-woven fabric are connected through a system causing the fabric to feel similar to felt. The texture of the fabric feels like felt. The non-woven geotextile offers separation, filtration, and drainage when used. There are several variations to choose from and the strength of the fabric is around 50 to 90 lbs grab tensile strength and above that it's good for hardscape installation under interlock and retaining wall projects as well as other drainage projects. This fabric is considered a commercial-grade landscape fabric versus a weed barrier fabric.

The drainage and reinforcement characteristics of non-woven and woven geotextiles are greatly different. Non-woven geotextile fabric goes beyond woven geotextiles and has been the focus for areas that require the ability of good drainage. For projects that include drainage flow, low static loads, pedestrian traffic, hard subgrades, and low dynamic loads, non-woven geotextile fabric is the best choice.

It's important where separation is required while still being able to allow water to drain similar to that of French drains. In one case, a perforated drain pipe was enclosed by stone and covered with non-woven fabric. The water from the surface can absorb through the non-woven geotextile fabric through the clean stone and then into the drainage pipe. Filtration of water through the fabric will only remove contaminants in the water but will not remove the subgrade or soil around the filter.

Non Woven Fabric With Gravel

Another important feature of non-woven geotextile fabric, you can apply a concrete overlay. The overlay was made of a hard substance not needing to be stabilized or reinforced It's necessary that any water entering the system will drain out through the filter and non-woven geotextile is highly recommended for this process.

Non-woven geotextile fabric is normally used for retaining walls while woven geotextile fabric is used for the foundation or base of the retaining wall. The remainder of the wall can be covered with non-woven fabric as the lateral and top section of the fabric creates separation, filtration, and drainage but not reinforcement. Water will enter the backfilled areas of the wall into the drain without removing the subgrade and soil material.

Geogrid is used along with non-woven hardscape fabric to provide reinforcement or stabilization of the base material that's placed on top. The non-woven geotextile is installed for separation, filtration, and drainage with the geogrid installed directly on top for reinforcement or stabilization. Non-woven geotextile is flexible where woven is not, so aggregate can get through the apertures of the geogrid and operate correctly.

How To Use Landscape Fabric

The minimum overlapping of the geotextile pieces should be 12 inches but can increase when dealing with a softer subgrade. The pieces should be shingled under the following piece away from the foundation. The cut pieces of geotextile must be in tension as the base, material is being prepared on top of it. The material must be smooth with all wrinkles removed for dumping gravel on top then prepare your base. It's important that the fabric will wrap up the sides to offer further separation of the subgrade from the sides into the base material.

The separation of the subgrade from the base material is one of the benefits of using geotextile. In the case of our example of a heavy object landing in mud, When the material is put under pressure it will move horizontally and probably upward as well. The separation of the subgrade under the tension of the geotextile will prevent any upward movement of the subgrade into the base material by spreading the load over a larger area and stopping the horizontal movement of the subgrade into the base material.

There are many benefits to installing geotextiles in your hardscape or landscape projects. Keep in mind when choosing the correct geotextile for your project. You must also consider the longevity of your hardscape or landscape project.
