Where to apply?
PENNTECH™ PRE HDPE self-adhering waterproof membrane is specially designed for underground structure waterproofing(e.g. basement, foundation), supports pre-applied construction method. Its pressure-sensitive adhesive requires less process during construction, the whole layer will firmly stick on the foundation and become part of the building.
Why it is so superior?
√ Weldable- Tight joint, leakage risk free.
√ High Elongation- Easy to apply, super adaptation to any structure, breaking risk free.
√ Sticky Back- Excellent bonding performance, application as easy as pie.
√ Pre-application- Be part of the building foundation, no leakage risk, no maintenance needed.
√ ISO&CE authorized- Reliable quality, keep your project safe and sound.
√ Thorogh pre-engineered system- make detail treatment perfect& easy.
How to apply it?
The surface to be applied must be solid and smooth. The application surface may be damp, but no puddles. In order to prevent damage to the membrane, the application surface must be smooth and clean. Large openings and voids should be filled using materials with the required strength.
To ensure good adhesion, the joints must be tightened with a roller. Roll finish edges should be taped with Double Tape in corner and piece combinations. In the production of single face curtains, it is necessary to create a smooth bottom surface without spaces.
