FAQ
When do you use root protection and when do you use root guidance?
The fixed rule when making this decision is:
- Will the screen be placed within 2 meters of the tree? Then choose root guidance.
- Will the screen be placed further than 2 meters from the tree? Then choose root protection.
A root protection screen cannot be placed too close to a tree. The smooth material allows the roots to grow around it, causing the risk of the "flower pot effect". This means that the tree does not have enough grip in the ground, which could cause it to blow over in a storm. With a root guiding system, the roots are guided downwards with the aid of vertical guiding ribs and this prevents a "flower pot effect" from occurring.
If RootBarrier® 325 is not placed correctly (smooth side not facing the tree roots), how effective is it?
The product will not be effective when places incorrectly. The smooth side of the RootBarrier® 325 prevents the roots from getting a grip and forces them to grow back. If the uncoated side is placed on the side of the tree roots, the roots can start to nestle in the fabric. This will cause irregularities in the fabric which means that the guarantee can no longer be given. If you want to be on the safe side, we recommend the RootBarrier® 360. This root protection screen is provided with a double coating.
Can I use RootBarrier® 325 instead of HDPE, for example?
Yes, the functionality is the same. In addition, our RootBarrier® root barrier is quick and easy to install. It is lighter in weight and easier to cut than HDPE. For example, a roll of HDPE 1mm 25 m x 100 cm weighs 27 kg and a roll of RootBarrier® 325 25 m x 100 cm weighs 8 kg. Thanks to the high quality of the RootBarrier® products, a 25-year guarantee is given on the root-resistant effect upon purchase (according to our guarantee conditions). However, the lifetime is more than 50 years.
What installation depth should the RootBarrier® 420 UV reach when protecting against bamboo?
We recommend a minimum installation depth of 1 meter for the RootBarrier® 420 UV. The exact depth depends on the type of bamboo, the quantity, the type of soil and the groundwater level. If you would like advice on the correct installation depth for your project, please contact our RootBarrier specialists. They will be happy to look at it with you!
