The Rootlok System

The Rootlok Vegetated Wall System is an engineered environmentally friendly system specifically designed for earthen structures. The system provides a reinforced facing for walls and slopes, protecting surfaces from erosion and offering an ideal medium to achieve a sustainable green finish.

The Rootlok Vegetated Wall System consists of two primary elements that combine to form a solid yet flexible structure, both of which are made in the UK. The engineered system is designed to provide a permanent soft solution for green walls and retaining structures, delivering long term erosion control whilst creating sustainable and environmentally enhancing schemes.

The Rootlok bag

At its core are the Rootlok bags, each weighing 30kg
and filled with a high-organic-content growing medium that promotes rapid germination and supports the establishment of grasses, plants, and shrubs.

This medium ensures a free-draining system, preventing waterlogging and fostering healthy root development. The bags can be pre-seeded, hydroseeded, or planted, offering flexibility to suit a variety of project requirements.

The Rootlok plate

The Rootlok Plate is manufactured by injection moulding using talc filled polypropylene and uses wholly UK sourced recycled material. The result is a consistently high-quality product that has great resistance to naturally found alkali's and acids within the ground.

The Rootlok Plate must be used throughout the system. The plate joins the gap between the bags and locks each one in to position to form a solid structure.

Bag fill material

The material used to fill each bag is an engineered blend that creates a free draining system with sufficient nutrients to gain a sustainable green finish. It consists of a mixture of soils, compost and sands that are free from pollutants and are of a grade that will support the growth of vegetation.

Installation

One of the key benefits of Rootlok is how easy it is to install unlike hard edge structures such as concrete, stone, block, panel and gabion systems. This allows it to be used in locations with difficult and varied terrains that are not suitable for traditional methods.

The Rootlok System can be used to build structures up to 10m or higher. There are numerous construction methods dependant on the wall type and height, loadings and other specific site conditions. The simplicity of the system allows it to be installed by individuals with ease.

Vegetation

One of the major benefits of the Rootlok System is its ability to integrate vegetation within the structure. Not only does this deliver on Rootlok’s green credentials but ensures longevity of its 120 year design life. We recommend several methods to vegetate the Rootlok structure: pre-seeding the Rootlok bags, hydro-seeding and inserting live plants.
