Type 1 Geotextile Fabric - Non-Woven



The type 1 geotextile fabric is composed of polypropylene and is designed for use in applications such as retaining walls, drainage and soil separation projects. The commercial-grade non-woven geotextile is permeable and allows for a high water flow rate while retaining dimensional stability. The fabric is rot and mildew resistant and is designed for permanent installations. Our type 1 geotexitle is available in a wide variety of different weights and roll sizes to suit nearly any application.

Note: Use the specification sheets below to match the specific fabric to your project’s requirement. The definition of a type or class of geotextile can vary depending on the specific municipality’s definition. Please be sure to check with your project engineer or municipality to ensure that this fabric matches their definition of a type 1 geotextile fabric.

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

The Difference Between Woven & Non-Woven Landscaping Fabric

Woven And Non-woven Geotextile Fabric

Landscapers and gardeners alike realize how important landscaping fabric is for their gardens or any hardscape project they have in mind. This fabric will reinforce, separate, and filter while allowing for good filtration and drainage. That said, not all landscaping fabrics are the same or right for every project. Because there are many different fabrics on the market, you need to know which fabric will work best for your project before making a decision.

Woven and non-woven fabrics have their weaknesses and strengths when it comes to installation depending on their characteristics. In the following, we will go over their similarities and their differences as well as where they should be used in a hardscape installation.

Different Kinds Of Landscape Fabrics

Geotextiles offer reinforcement, separation, filtration, and drainage. This is important for areas with subgrade elements that are saturated for periods of time during the year or if your area has several freezing and thawing cycles during the winter months.

Separation of the soil subgrade from the base is important in order to prevent the movement of the subgrade into the base material. The upward movement of the subgrade into the base material is caused by the load the pavement bears. As an example, if a heavy object is pushed down into the mud, the mud will spread upward and horizontally. We will go over more about this later on.

Reinforcement or Stabilization using landscape geotextile will help to spread the load over a greater area of the base because the geotextile is in tension and gives the base tensile strength.

Filtration of geotextiles will allow water to spread out and over a wider area while maintaining greater control over the drainage of water.

Drainage will help water flow freely through the geotextile fabric.

There are some factors you have to take into account when choosing the best fabric for your project. Before choosing the fabric, there are a few other things you need to understand about woven and non-woven geotextile fabrics and their best characteristics in order to get what will work best for your project:

Woven Geotextile Landscape Fabric

Most woven geotextile fabric is made of polypropylene filaments connected to a network that offers more stabilization and strength than non-woven fabric. The woven geotextile fabric offers filtration, separation, and reinforcement.

Geotextile woven landscape fabric is used for very active, as well as motionless load projects including driveways for extra reinforcement to the base by spreading the load over a larger area. If the subsoil is soft and not stable and water is not a regular occurrence for penetrating the subgrade, then woven geotextile fabric is not that important.

That does not mean that drainage is not important because it is. You will have to install solid or perforated pipes and drains to collect the water and remove it from the system. If you don't, the water will stand and form a reservoir that will stay there for a long time then lead to future problems.

Non-Woven Geotextile Landscape Fabric

Non-woven geotextile fabric is made of polypropylene fibers that are connected at random through the network. These fibers are small, creating a fabric that feels a lot like felt.

This non-woven fabric offers filtration, separation, and drainage. There are a number of different non-woven fabrics to choose from. The fabric's strength is usually 80 to 90 grab tensile strength and is a good choice for hardscape installed under interlocking and retaining walls as well as other landscape drainage projects. This product is a commercial-grade fabric versus a weed barrier fabric.

The differences between woven and non-woven textiles are the drainage and reinforcement qualities. Non-woven textiles are water-permeable landscape fabrics with excellent drainage in comparison to woven textiles. Drainage is the major focus for areas that require excellent drainage capabilities. For projects that experience fewer activity loads, pedestrian traffic, less static loads, hard subgrades, and that water must flow freely, non-woven geotextile is the right choice for you – not woven geotextile.

This is critical for projects that require separation of material from cross-contamination while still having the ability to allow water to drain through it, such as French drains. In this project, a perforated drainage pipe is surrounded by a clean stone and then wrapped around with non-woven geotextile filter fabric. The water from the surface will penetrate through the fabric, through the clean stone, and into the drainage pipe without disturbing any of the elements around it. This also applies to hardscape projects that require the same functions.

Another hardscape project that requires non-woven geotextile is a concrete overlay. Concrete overlay is a hard material that does not require reinforcement or stabilization but does require that any water that enters the system must drain through, and then filter out of the system. It's highly recommended to use non-woven geotextile fabric for this project and other projects like this.

Also, non-woven geotextile fabric is the chosen product for retaining walls while the woven fabric is great for the foundation. The rest of the wall can be covered with non-woven fabric as the properties of the lateral and top areas of the fabric are for separation, filtration, and drainage but not for reinforcement. This will let water penetrate the backfilled section of the wall and then into the drain without displacing the subgrade and soil material into the backfill material.

How To Use Landscape Fabric

To install the geotextile properly, the minimum overlap from one piece to another should be 12 inches and increased as the subgrade becomes softer. The pieces should be shingled away from the foundation meaning the pieces from the foundation should be placed under the next piece allowing water to move from one piece to another without getting under a piece of fabric. As the fabric is rolled out and cut, the pieces must be in tension as the base material is being prepared on top of it.

All wrinkles must be smoothed out or removed before dumping gravel over it and preparing your base. Where possible, limit the amount of fabric you cut. Also, when installing the fabric, make sure it will wrap up the sides of the project to increase the separation of the subgrade from the sides into the base material.

One of the benefits of using geotextile is the separation of the subgrade from the base material. Referring back to pushing a heavy object into mud, the material will move horizontally but the material under pressure from the load will move upwards as well.

The separation of the subgrade under tension of the geotextile will stop the upward movement of the subgrade into the base material by spreading the load out over a larger area. This also prevents the horizontal movement of the subgrade from the sides of your excavation into the base material.

There are several benefits to installing geotextiles in your landscape or hardscape project. There are several factors you must take into consideration before choosing the best geotextile for your project. In this article, you will get help choosing the right product for your project's extended life and make sure you follow the directions and recommendations in order to install the geotextile the right way.
