duplas p anti root

Technical Data Sheet

DUPLAS P ANTI ROOT is an excellent anti root, APP-modified bitumen waterproofing sheet membrane with a special compound to prevent the root penetration. It is absolutely root proof and widely used in green roof systems. The topside is covered with a special foil or sand or slate and the bottom layer with a polymeric foil.

OUTSTANDING FEATURES
  • Excellent anti-root property.
  • Self-sealing to minor cracks.
  • It can be used for interior garden system or exterior green roofs.
  • Highly resistant to dilute acid and fertilizers.
  • High resistance to ageing.
  • High elasticity and flexibility.
  • High tear resistance.

Uses

  • Root-proof under layer.
  • It can be used either a single layer or a part of Duproof two-layer anti-root sealing system that is used for waterproofing and root proofing of green roof system.
  • The membrane is used for interior garden system as well as for exterior roof garden systems as protection against root penetration.

METHOD OF APPLICATION

The application of DUPLAS P ANTI ROOT roofing and waterproofing membranes are easy and fast by the torch–on method. Clean the surface to be waterproofed and prime with Duproof Primer and allow to dry. The drying time depends on the porosity of the substrate and the environmental conditions (approx. 0.5 – 3 hrs.)

The membranes are then unrolled and aligned properly on the entire primed substrate, allowing overlap joints of 100 mm at the sides and 150 mm at the end.  Roll back the membranes without disturbing the alignment. Apply gas torch on to the contact area of the membrane and the substrate. Ensure enough melting at the bottom to form sufficient melt adhesive to stick on to the substrate. While torching, forward the roll and press firmly to bond the membrane on to the substrate. Then, smoothen out seams by means of a rounded trowel. This system of application can be used on concrete, concrete blocks, bricks, foam concrete, fibre cement board and steel substrates. Care must be taken when torch bonding with heat sensitive substrates.

The APP modified sheet membrane is versatile and flexible that can be applied using pour and roll application method and cold bond applied method. For technical instruction refer to Duproof Application System.
