Barriers are flexible, high-performance membranes typically used in brownfield and redevelopment sites or sites with contaminated ground. We have a range of products including Japanese Knotweed Barriers, Hydrocarbon Barriers and Gas Membranes.

Japanese knotweed barrier

Japanese knotweed can grow up to a rate of 10cm per day, because of this it has been known to cause damage to both building structures and biodiversity. It targets weak points in building structures such as cracks in stone and brickwork and tried to grow through them. It also affects ecosystems by crowding out native vegetation and limiting plant and species diversity.

A Japanese Knotweed barrier is a flexible, reinforced membrane that protects structures and stops encroachment of knotweed root. It is often used in conjunction with other methods to prevent the plant’s spread, such as herbicidal treatments, excavation, screening, and sifting.

  • Protection of building structures
  • Contaminated sites

Hydrocarbon barrier

Hydrocarbon Barriers are flexible membranes designed to protect developments and installations from latent hydrocarbons. They are made of high-quality raw materials which give them high mechanical strength, excellent UV resistance, and resistant to roots. They can also be easily installed without wrinkling.

Hydrocarbon barriers are made up of polyethylene macromolecules which provide superior resistance against many chemicals and are also environmentally safe. They do not contain any plasticizers, fillers, micro biocides, or other substances which could be leached out by substances in soil, water or produced by roots. Therefore, Hydrocarbon barriers are an excellent choice for environmentally sensitive projects.

  • Brownfield and redevelopment sites
  • Contaminated ground
  • Highway construction and associated surface drainage systems

Gas Membranes

Gas Membranes are ultra-low permeability high-performance membranes for use in situations where resistance to Methane, Radon, CO² gases and Hydrocarbon vapours is required. They are generally used within construction applications, predominantly within the foundation design.

They also provide additional damp proofing protection and negate the need for a separate damp-proof membrane.  The multi-layered, loose-laid reinforced membrane construction means they typically have an excellent puncture and tear resistance.

  • Foundations of buildings
  • Basements
  • Contaminated industrial sites
