Root & weed barriers

CaRoot 325 is the universal, vertically - deployed protector against roots for professional use in underground engineering, gardening, landscaping or the construction of paths. The special coating on a highly non-tear fibrous web stops the uncontrolled growth of roots. Due to this, typical problems such as damaged pipes and the necessary works in the case of uncontrolled root growth can be avoided.

CaRoot 325 is a combination of a highly reliable geotextile and a special PP-coating. This guarantees the impenetrability of roots, a high level of resistance against bacteria / chemicals and at the same time, water resistance. Despite the strength of the product, it can be processed easily by hand. CaRoot 325 is also 100% recyclable. Subject to technical modifications.

Fields of application

• Vertical ‘partition panel’ between the plant and the pipes, cables or foundations
• Vertical ‘partition panel’ between the plant and the paving and/or path building
• As wrapping, permanent protection of pipes or lines
• Creation of targeted, long-term root growth


• 25 years warranty for protection against roots*
• Impenetrable for roots
• 100% water resistance
• Heavy duty, light and flexible
• Simple installation
• Resistant to bacteria and conventional chemicals
• 100% recyclable

In order to connect individual sections, we recommend CaRoot Click Connection. The use of CaRoot 420 UV should be especially considered in the case of aggressive root growth or natural weathering. For light covering work, we recommend CaGround.

* Before making a claim against the 25 years root protection warranty, please follow the CaPlast laying instructions and make yourself aware of the warranty provisions.
