Overview
JX-705 PET self-adhesive waterproofing membrane is made of rubber modified asphalt self-adhesive material containing active additives as the main material, with polyester film (PET) as the surface reinforcement material on the upper surface and isolation film (paper) on the lower surface. It can be constructed by self-adhesive method (dry laying method) or cement adhesive (wet laying method), and can also be combined with rubber asphalt waterproof coating to form a composite waterproofing system. It is a tireless self-adhesive polymer modified asphalt waterproofing membrane that can meet the construction requirements of different base conditions.
Features
l Strong bonding force, good extensibility of the self-adhesive layer, and strong ability to adapt to structural deformation.
l The overlapping seams of the roll materials are glued, and the overlapping and airtight performance is more reliable.
l The coil is soft and conformable, and has good construction tolerance.
l The fine cracks caused by nail rod penetration or external stress can heal themselves under the action of building load gravity.
l It has high reflectivity to sunlight, and short-term exposure can avoid UV and heat aging of the coil.

Installation
Self-adhesive method.
Application
It is suitable for underground waterproofing projects and non-exposed roof waterproofing projects
Notes
1. Before the roll material is installed, avoid exposure to the sun to prevent the temperature from being too high and the isolation film from being difficult to tear open.
2. The joints of the roll materials should be dense.
3. Operations should be stopped in severe or extreme weather such as strong winds of level 5 or above, rain, snow, etc.
4. Before constructing the waterproof layer, the embedded parts must be installed and fixed to avoid drilling holes after the waterproof layer is constructed,
which will damage the waterproof layer and leave hidden dangers of leakage.
5. After the roll material is laid, areas that are directly exposed to sunlight for more than three weeks should be covered and protected with plastic sheets or other materials.
