Cycle Paths - Technical Information
Cycle path enhancement
Polypipe is able to offer a number of products that may be used to enhance the water management capability of cycle paths and to protect the root zone of trees and shrubs adjacent to new cycle path construction.
Where the Polypipe Permavoid unit is incorporated in to the cycle path construction, it may be constructed:
- As an attenuation or infiltration system (may include an appropriate geosynthetic root barrier), the Permavoid unit effectively creates an air void within the pavement; discouraging root growth within the pavement, but can also be used to ensure penetration of moisture and air into the root area
- With an infill of a suitable growth medium, the Permavoid system ensures this soil does not become compacted, allowing room for future root growth while facilitating the penetration of moisture and air
Surface water management
Significant surface water management benefits may be gained from cycle paths if they are constructed following the same principles as a permeable pavement. Increasing the potential attenuation storage provided within the granular sub-base material can be achieved through the substitution of sub-base material with units from Polypipe’s Permavoid product range.
