How To Prep & Install Geotextiles

What Type Of Geotextile Do You Need?

Brought To You By Our Associates Spudulica

Before you even think about installing a geotextile fabric you need to figure out which type you need. If you are laying the geotextile in a very high traffic area or a high weight loading area then chances are a woven membrane is what you need, although keep in mind this doesn’t provide a massive amount of permeability or filtration. On the other hand, if it is somewhere that generally doesn’t have a massive amount of high loading traffic and is mainly used for foot traffic or general domestic usage then a non-woven membrane will likely be your go-to.

 

Preparing Your Geotextile

Now that you know what type of geotextile you need you can start with the prep work to lay it. To start with you will need either a new Stanley knife or at least a couple of fresh blades or if your cutting a low GSM membrane sharp scissors should do the job (keep in mind if you are cutting high GSM membrane scissors will not work) If you have a lot of material to cut please refresh your blades frequently as using a blunt blade can fray the membrane and never use scissors on a woven membrane.

Cutting Your Geotextile

Woven: If you have opted for a woven membrane your best bet for cutting it is to lay it down in place and then clean up the edges by cutting it as smoothly as you can using a sharp Stanley knife. Once cut you need to be cautious with the membrane to reduce fraying and trust us the strands do get everywhere! Non-Woven: If you have opted for a non-woven membrane we suggest you lay the membrane down and have someone hold it in place to stop it moving while you cut then slice through it with a sharp Stanley blade.

Installing Your Geotextile

Now that you have completely prepped your geotextile for installation you can start to prepare the area of installation. To start with you need to prepare the ground by removing any grass/shrubs/stones. Once all blemishes have been removed you need to make the ground flat and fill in any holes that are left from your removals. Now that the ground is prepped you can lay your geotextile over the area making sure that it is flat against the ground. Once you are happy with how you’ve laid it you need to secure it tightly into place using pegs/pins on each edge, we suggest 1 pin/meter used. You can now begin to lay your overlay whether this is aggregate or decorative material.
