Cellweb® TRP: The Leading Tree Root Protection System

Yes. Cellweb® TRP is explicitly stated to be fully compliant with BS5837:2012 and APN 12.

Key compliance factors include:

• No-dig construction in accordance with BS5837 requirements for tree root protection.
• Designated for use within Root Protection Areas (RPAs) with no excavation and strict protection against soil compaction, both of which are required by BS5837.
• Meets BS5837:2012 technical requirements for three-dimensional cellular confinement systems for load distribution around tree roots.
• Ensures continued water and oxygen permeability, preserving root health as required under BS5837.

Yes, in most cases. Cellweb® TRP is widely recognised and routinely accepted by UK planning authorities because:

• It is fully compliant with BS5837:2012, the standard used by local authorities when assessing development near trees.
• It is a no-dig system, which tree officers typically require within RPAs.
• It has been adopted by councils and used on local authority projects, including footpaths and infrastructure within RPAs.

Most planning authorities request a method statement and drawings based on accurate ground conditions (CBR value), but normally approve the system when it complies with BS5837.

Yes. Cellweb® TRP is specifically designed for installation within Root Protection Areas (RPAs) / Tree Protection Zones.

• It is described as a no-dig tree root protection measure, intended for construction directly within RPAs.
• Evidence shows it reduces soil compaction, protecting roots even under vehicular traffic.
• It enables installation without disturbing the soil profile, which is a fundamental requirement inside TPZs.

Yes. Cellweb® TRP is suitable and regularly used on sites protected by TPOs.

• • The system is compliant with TPO guidelines, as stated in manufacturer and third-party documentation.
  • TPOs require strict non-invasive measures such as no-dig construction and minimal compaction, both of which Cellweb® TRP provides.

As long as the installation method follows the arboricultural method statement and local authority guidance, Cellweb® TRP fully satisfies TPO protection requirements.

Yes — Your Cellweb® TRP is the only tree root protection system on the UK market that has undergone independent testing. Testing was carried out by The Environmental Protection Group Limited.

• • It is explicitly stated to be independently tested, making it unique among TRP systems in the UK.
  • It has also undergone performance trials showing reduced sub-soil compaction, referencing work based on independent field trials.
  • Long-term tree vitality assessments further support its effectiveness in maintaining tree health after installation.
