Geotex (Fabric) Runway
(Information Only)

For more information, please visit EcoGeoX.

Many radio controlled aircraft clubs throughout the United States are using a Geotextile runway as an alternative to asphalt. The Geotex runway offers many advantages as it is affordable, and it provides a smooth surface so all sizes and types of aircraft can use it. This page will explain all the details of the Geotex runway. At the bottom of the page, you can place a vote. If our club expresses enough interest, we too could have a Geotex runway.

What Is Geotextile?
The fabric is used as an underlayment in road construction as a porous barrier between gravel and earth. Water filters right through it, but (as long as it is in contact with the ground below) it tends to keep the underlying earth below it from eroding. There are many different varieties, all designed to meet government specifications for either puncture strength, tear strength or porosity. Its main weakness is that it will degrade over time due to UV exposure. The time span is 5-7 years of use before needing to consider replacement. It is a petroleum-based material, so pricing varies widely and changes day-to-day.

Easy to Install
A Geotextile runway is also fairly simple to install. Blade the runway area, or remove all weeds with a post-emergent weed killer such as Roundup®, and fill in low points. Compact the area, making sure to establish a crown and allow for drainage on the sides. Rake out bumps and rocks. Apply a pre-emergent weed killer such as Preen. Unroll the Geotextile onto the prepared runway area. Secure the Geotextile by driving in 8&#; sod staples to just slightly below grade level. Use staples every 18 inches. Overlap Geotextile edges 6&#; or so and glue it with something like Black Jack® brand Emulsion Roof Coating. Another option is 3M&#; #78 Spray Geotextile Adhesive.

Southern Eagle Squadron in Leesburg, FL have discovered another way to seam two sections of Geotextile together. They utilized a product available at Home Depot called Tite Seal &#;Roof Deck Seam Tape.&#; They are very pleased with the results. As an added bonus, the tape is white, creating a white strip down the middle that many clubs prefer!

Seminole Valley RC Field completed the installation with Willahoochee 315W Geotextile material. This runway replaces the old existing grass runway which was rough and made takeoffs and landings very challenging. The club installed 3 rolls of Willahoochee 315W geotextile fabric and secured it with sod staples to complete a runway that is 30&#; wide by 300&#; feet long. The installation was completed in just a few hours.

Below is a video of the Central Savannah River Area Flyers installing their runway on grass.

CSRA Flyers completed the installation of our brand new runway made from 315W geotextile material. This runway replaces the old existing grass runway which was rough and made takeoffs and landings very challenging.

A crew of 15 club members installed 3 rolls of Willahoochee 315W geotextile fabric and secured it with ~2,800 8&#; sod staples to complete a runway that is 45&#; wide by 300&#; feet long. The installation was completed in just 2 hours and 45 minutes!

There are several methods the Geotextile runway can be repaired.
There are many ways to repair a Geotex runway. An adhesive used to apply patches is called GOOP found at Home Depot, as well as other retailers. The GOOP patches take about 20 minutes to dry enough to use the runway and they seem to hold up really well. We repair holes using small pieces of the fabric and asphalt roof patching compound. Some of the smaller holes can be repaired using just the asphalt roof patching. A good idea is to use round corners on the patch material to lessen the chance of them pulling up.

Questions and answers

How do I seam Geotext?
Since sewing will produce humps that are not acceptable, the product will need to be glued or bonded. Gluing polypropylene can be problematic. Our clubs have told us of several options that work. These are Black Jack® Emulsion Roof Coating, 3M&#; #78 Spray Geotextile Adhesive, Goop® glue and Tite Seal Roof Deck Seam Tape.

Where can I purchase sod staples?
They are usually available at Home Depot, Lowes or your local sod supplier. Make sure to get staples with a flat top. Some have a rounded top that can protrude up after installation.

How long will my Geotextile runway last?
Each installation is unique. However, clubs are typically reporting 5-7 years of use.

Does a Geotextile runway need to be pulled up every year?
No. You do not want to pull the runway up. This can result in damage to the geotextile. It will also be difficult to re-roll it into a manageable size without a mechanical apparatus to tension it while it is rolled.

How do I remove snow and other debris from geotextile runway fabric?
A blower or broom is the best option to ensure you do not damage the fabric.

The roll has numerous fibers sticking out on the ends. Is it unraveling?
No. This is how the finished rolls appear. This is not a defect. You will notice that the rolls have a thick selvedge about an inch or so in that prevents unraveling.

What preparation is needed before laying the fabric?
The ground is rolled and the grass is mowed as short as possible. You can kill the grass off with spray to help the fabric lay down faster.

How is it installed?
It is held down by 8&#; staples approx. 6&#; apart at all edges and seams.

What maintenance is required during the season?
The only maintenance required has been to kill a few weeds working up through the seams and to patch a few bad prop strikes.

What needs to be done each spring?
Roll the field and push the staples down. They work up a little due to the frost in the ground.

Any winter preparation needed?
No winter prep has been needed.

What are the top three problems with the fabric runway?
(A) Short coupled planes or planes with poor landing gear tend to be real squirrelly
at taxiing and take off.
(B) You must have a very slow idle.
(C) If a plane noses in or crashes on the runway really hard, it can put the prop nut through the runway or the prop may slice through. However, most of the time it does no harm.

Why do other clubs go to a fabric runway?
Because a lot of the guys did not like having to put larger wheels on their airplanes in order to take off from the tall grass, especially in the spring when the grass grows so fast.

How do other club&#;s members like the fabric runway?
Most of them like it, even those who originally opposed it. One particular club maintains approx two (2) acres of mowed field for anyone who still prefers to fly off grass.

What care must be taken while mowing? How close do you get to the fabric?
Our mower just overlaps the edges of the runway and has had no problems.

Does it stay tight?
The runway material stretches tight in the sunshine and stays tight all year round.

Does the wind damage the runway?
There have been no problems with the winds damaging the runway, but the runway must be securely installed with sod staples.

What is the cost estimate?
For one roll of Geotex &#; Mirafi® FW404 compairable to US230, 15ft. wide X 300 ft. Long &#; price is $1,940 + $60 to truck it from Salt Lake to WAM.

What is the average size of runway other clubs are using?
The average runway width and length are 30 feet X 300. For our club we would need a minumum of 2 rolls of Mirafi® FW404. This bid is through Nilex &#; Salt Lake City.

Geosynthetic are synthetic fabric that are utilized to enhance the performance and stability of soil and other fabrics in civil engineering tasks. They can have different uses, such as strengthening, parting, filtration, drainage, safety, and barrier. In airport and runway construction, Geotextile fabric for waterproofing can provide many advantages, such as decreasing expenses, saving time, increasing protection, and minimizing environmental effects. In this post, you will discover about some of the major applications and benefits of utilizing Geotextile Fabric in airport and runway construction. 

Strengthening and Stabilization 

One of the most usual usages of woven geotextile fabric in airport and runway construction is to strengthen and steady the subgrade, base, and surface coating of the roadway. Geotextile Fabric can deliver tensile strength, difficulty, and resistance to the soil and total fabrics, averting them from distorting, cracking, or rutting under heavy weights and frequent traffic. Geotextile Fabric can also decrease the density and quantity of the pavement fabrics, resulting in lower structure and maintenance expenses. Some instances of geosynthetic utilized for strengthening and stabilization are geogrids, geotextiles, and geocells.

Separation and Purification 

Another important uses of Geotextile Fabric in airport and runway construction is too distinct and filter various fabrics and liquids. Geosynthetic can avoid the mixing of the subgrade and the base or surface coatings, conserving the reliability and performance of the path. Geosynthetic can also purify water and air, enabling them to go through while holding soil particles and pollutants. This can avoid the blockage and corrosion of the drainage procedures, as well as the frost heave and thaw fading of the subgrade. Some instances of geosynthetic utilized for separation and filtration are geotextiles, geonet, and geocomposite. 

Drainage and Waterproofing

A third crucial role of woven geotextile fabric in airport and runway construction is to deliver drainage and waterproofing options. Geotextile Fabric can ease the discarding of additional water and dampness from the pavement coating, decreasing the threat of saturation, swelling, and worsening. Geotextile fabric can also work as a barrier to avoid water infiltration from the texture or groundwater sources, safeguarding the subgrade and the pavement from damage. 

Protection and erosion control

A fourth crucial advantage of woven geotextile fabric in airport and runway construction is to safe and control corrosion of the soil and the pavement. Geosynthetic can cushion and engross the effect of the construction tools, aircraft, and vehicles on the pavement texture, decreasing the wear and tear and enhancing the service life. Geosynthetic can also cover and steady the soil slopes and ridges around the airport, avoiding them from being worn by wind, water, or ice. Some examples of geosynthetic utilized for safety and corrosion control are geotextiles, geomat, and geocells. 

Ecological and Visual Development

A fifth and final benefit of Geotextile Fabric in airport and runway construction is to enhance the ecological and aesthetic aspects of the task. Geosynthetic can decrease the carbon footprint and the energy ingesting of the construction procedure, by utilizing less natural resources, producing less waste, and needing less shipping and machinery. Geosynthetic can also increase the appearance and the functionality of the airport, by delivering green spaces, noise lessening, and wildlife safety. 

Functions of Geotextiles

The procedure of operation of a geotextile in any application is distinct by six separate meanings:

Separation

The separation purpose of non-woven geotextile fabric is largely used in the making of roads. Geotextile avoids the mingling of two together soils. For example, by unravelling fine subgrade dirt from the mixtures of the base course, the geotextile preserves the drainage and the power characteristics of the total fabric.

Some of the relevant regions are: 

• Between subgrade and stone base in unpaved and concreted roads and airbases.

• Between subgrade in railway trails

• Between landfills and stone base expansions.

• Between geomembranes and soil drainage layers.

Filtration 

The regularity of geotextile-to-soil process that consents for satisfactory liquid flow with restricted soil loss across the plane of the geotextile. Porosity and permeability are the main aspects of geotextiles which contain penetration action.

Reinforcement

Summary of non-woven geotextile fabric in the dirt raises the ductile strength of the soil the same quantity steel does in concrete. The strength development in soil due to the summary of geotextile is by the following 3 contraptions:

• Contiguous control through interfacial confrontation between geotextile and soil/cumulative. 

• Impressive the possible bearing external failure plane to change an advanced shear power external.

• Membrane type of sustenance of the wheel weight.

Sealing

A covering of non-woven geotextile fabric is soaked in between current and new asphalt layers. The geotextile grips asphalt to become a waterproofing membrane decreasing perpendicular undertaking of water into the roadway structure. 

Usages of Geotextile in Construction

The prospect of geotextile in the construction area is very huge. The application of geotextile is provided under the banner of the nature of work.

Road Work

Geotextiles are mainly used in the structure of the road. It reinforces the soil by collecting tensile strength to it. It is used as a quick de-watering coating in the roadbed; the geotextiles needs preservative its permeability without trailing its unscrambling functions.

Railway Works

The woven textiles or the non-woven ones are used to separate the mud from the sub-soil without hindering the groundwater flow where the ground is rough. Invasive individual layers with material avoid the fabric from itinerant off sideways due to quakes and sensations from running trains.

Agriculture

It is used for soil control. For the expansion of murky paths and trails those used by cattle or light traffic, nonwoven fabrics are used and are creased by overlying to containing the pipe or a mass of grit. 

Drainage

The uses of geotextiles to strained the soil and a more or less single size ground fabric to ship water is increasingly seen as a strictly and commercially viable auxiliary to the traditional structures. Geotextiles fulfill the filtering device for drainages in earth dams, in roads and highways, in lakes, behind absorbent barriers, deep drainage drains, and agriculture.

River, Canals and Coastal Works

Geotextiles protects river arrays from erosion due to currents or slurping. When used in combination with natural or artificial enhancements, they work as a filter.

Conclusion

In today&#;s post we get to understand about Geotextiles, its categories, functions & usages. Geotextile is a crucial component in construction industry. If you want to buy any type of Geotextile fabric then just approach Singhal Industries as they have a vast experience in manufacturing of all kinds of Geotextiles.

Frequently Asked Questions (FAQs)

What is geotextile fabric used in road construction?
It can be a geotextile, a geomembrane or a mixture of the two. Modern geotextiles are normally manufactured from synthetic polymers-polypropylenes, polyesters, polyethylene&#;s, and polyamides-which do not deterioration under biological and chemical procedures. This makes them beneficial in road structure and conservation.

Does geotextile fabric let water through?
Geotextiles can be utilized in separation to enable water to go through the covered coatings. Geotextiles are utilized to go water through but avoid other fine particles and soils from going through.

What is geotextile used for in construction?
Geotextiles are largely utilized in road structure, particularly to fill gaps between the roads to enhance soil layout.
