80mm Preloaded Geotextile Membrane Filter Sock Sleeve

This 80mm pre-loaded geotextile filter sock is pre-wrapped on a cardboard applicator for easy loading and comes supplied in 30mtr lengths. Most commonly used alongside 80mm perforated land drain pipes, however suitable for various types of perforated pipe drainage including PVC, straight wall and corrugated HDPE, steel and aluminium. If you require geotextile filter socks longer than 30mtrs take a look at our non-preloaded geotextile filter sock sleeves which are available in longer lengths and various diameters.

We recommend using the preloaded geotextile for pipes of at least 9mtr in length or longer for ease of installation. Installing pre loaded geotextile is a simple and easy to do. Starting with the outlet end of the pipe, simply:

• Fully expand the cardboard into a square and sleeve it over the end of the pipe
• At the outlet end of the pipe tie a knot in the filter
• While maintaining tension on the sock, slide the cardboard applicator over the length of the pipe
• Remove the cardboard from the pipe
• Leaving the outlet end open, untie the knot in the filter

Made from polyester resin, this seamless geotextile membrane is permeable so it will allow water to filter through the geotextile sock into the perforated pipe ensuring the continue flow of water. Created in a special knitted design, this geotextile sleeve wrap prevents silt, soil and sandy particles from entering perforated pipe preventing any unnecessary clogs and maintenance. Any particles that are small enough to make it through the filter sock will be transported with the water flow, eventually discharged from the drainage pipe.

Geotextile membranes used to only be available in large sheets which meant that installing geotextile around your pipe was difficult and time consuming. Originally, you would need to measure around the pipe and then make sure the wrap is secure in place, which would require multiple people to assist. With this easy preloaded cardboard applicator, it is designed to save you time with ease of installation by one person, eliminate any measuring mistakes and potential wastage of large geotextile sheets. These pre-loaded geotextile filter socks are a handy time-saver for any project that requires the protection of an underground drainage system for all soil types.

Unlike impermeable geotextile membranes which do not allow water to pass through, permeable geotextiles have opposite qualities. Permeable geotextile membranes are made from porous fabrics allowing water to pass through.  Geotextiles are manufactured from various materials ranging in thicknesses and styles including woven, non-woven and knitted. They all have their unique purposes for different job applications.

The fabric is manufactured by Carriff and specifically designed for drainage filtration using state of the art circular-knitting machines. Tested under various procedures for permittivity and puncture resistance, this assures the installer they are using a reliable product that will perform when correctly installed and handled.
