APP waterproofing membrane (-5°C)

Pre-fabricated waterproofing membrane made of distilled bitumen and elasto-plastic polymers (APP) having a woven non woven single strand composite polyester reinforcement, which provide the membrane with high mechanical characteristics and excellent dimensional stability. The V versions have a fibre glass reinforcement, with excellent dimensional stability. The versions PA are self-protected on the upper face with mineral slates which reduce superficial heat absorption improving the durability of the membrane. The self-protected versions have a side selvedge of 10 cm and upon request a head selvedge of 15 cm, to improve adhesion between the sheets.
On request an ANTI-ROOT version is available for green roof applications. The compound has a special chemical additive (PREVENTOL B2 BAYER) which provides the membrane with high resistance to root penetration, aggressive chemical agents such as fertilizers, weedkillers, etc. The anti root resistance of the product does not harm the health or life of the plants. The anti root additive does not wash out with water, and remain permanently active.
