Our products ProtectaWeb™Tree root protectionProtectaWeb is a proven no-dig method of enabling the creation of access ways or parking areas in close proximity to nearby trees. The unique composition and strength of ProtectaWeb™ ensures this can be done without compacting the soil, which can cause irreparable harm to the tree’s life support system. ![]() Prevent damage to tree rootsProtectaWeb is a matrix that contains and confines granular infill. This provides a stable, uncompacted, composite matrix with an enhanced angle of internal friction that significantly reduces the imposed loads on the soil and tree roots beneath. ProtectaWeb’s perforated cell walls give lateral drainage, minimising hydrostatic build up which ensures the maximum supply of water to the tree roots, even when installed on a gradient. On development sites soil compaction is the biggest threat to existing trees. Soil compaction forces air, minerals and water particles out of the soil leaving the tree root starved of the vital components needed for health. Compaction is caused primarily from the construction process or creating new paths, car parks or roadways above the root protection area of existing trees. This is usually compounded by site traffic using the site prior to any tree protection measures being in place. There are other factors which can cause harm to trees on development sites. These include:
![]() ProtectaWeb provides the solutionWrekin’s tree root protection system, ProtectaWeb™, is ideal for building roads, car parks, lorry parks, and pathways over the root protection area of existing tree roots. It can be designed to accommodate all types of vehicle loadings and soils without any digging required. The system is simply placed on the existing ground, filled and finished with a porous surface. The cells are filled with a clean angular stone which allows drainage and aeration through the cells. Two key components of the ProtectaWeb™ system are the special grading of the stone and the selection of the geotextile separator, placed below the ProtectaWeb™ How protectaweb tree root protection system worksLack of tree root protection can lead to

Design proposals and guaranteeWe can provide full design proposals for all ProtectaWeb components. The chart below can be used as a guide for initial project implementation. However, we always suggest the full requirements of your design be verified by our technical support team. In addition, we will guarantee ProtectaWeb Tree Root Protection System for 25 years, providing the ProtectaWeb strictly adheres to our installation recommendations and all system components have been used.
Note: This is general guidance for the depth of ProtectaWeb according to Gross Vehicle Weight for a firm and stable sub-grade (CBR.3%). If the ground conditions are poor and/or unstable please contact our ProtectaWeb team for a site-specific design on 01543 440432 or via email at sales@wrekinproducts.com.
