  • Scour Remediation
  • Free Span Correction
  • Structure Scour Protection
  • Concrete or Chain Ballasted

Our custom-designed frond mattresses are created specifically for the harshest marine environments. 

Benefits of our fronds include:

  • Ability to use longer 1.5m fronds due to the UV stabilised 200 Denier Woven PP on the base mattress
  • Improved reduction in velocity of current particles (up to 50% decrease)
  • Faster burial of surrounding subsea assets
  • Environmentally friendly due to the ability to act as a nursery for small fish

The fronds can be attached to concrete mattresses, grout bags, grout inflated fabric formworks or chain ballast. The fronds are secured for installation with a Velcro cover complete with buoyant monkey fist and a bridle for deployment. This allows the mats to be safely installed by ROV or divers.
