Replaces Index Defend H Root



Proofex Torchseal A700 is a polymer-bitumen waterproofing membrane with an antiroot additive, reinforced with a ‘nonwoven’ polyester fabric for protecting roof gardens, buried works and gravel covered roofs. The antiroot properties are obtained by adding a specific antiroot agent (esterified fatty acids and oxyphenols) to the polymer-bitumen compound.
Proofex Torchseal A700 forms a continuous 4.5mm thick barrier against roots, even along the overlaps, due to the fact that the entire compound which forms the waterproofing mass is activated. The antiroot additive does not migrate in the ground nor is it washed out by water and it is resistant to the heat produced by torch bonding the overlaps.
The reinforcement of the membrane consists of a ‘non-woven’ polyester fabric which is resistanant to puncture and tearing.
The underside of the membrane is coated with polyethylene film that melts when torched.


Proofex Torchseal A700 is applied as the final waterproofing layer in contact with earth for gardens, foundations, underground structures and tunnels covered with soil. When waterproofing roof gardens, it is used as the top layer of a system, the first layer being a polymer-bitumen membrane reinforced with ‘nonwoven’polyester fabric and the second being Proofex Torchseal A700 which is placed astride the overlaps of the previous layer and full bonded with the torch.
Proofex Torchseal A700 is used in waterproofing systems in contact with the ground or where there is a risk of the system being attacked by roots.
