Splicing method and laying of root puncture resistant waterproofing membrane

Root puncture resistant waterproofing membrane splicing 1, bonding with solidifying adhesive. Solidification adhesive mainly refers to polyurethane adhesive, polymer modified cement coating, etc. After the solidifying adhesive dries, it is riveted and bonded to the non-woven fabric on the surface of the membrane.
Adhesive mechanism: The surface of linear low-density polyethylene is roughened with composite non-woven fabric, forming a mesh like void structure on the surface of the coil, making it adhesive. When the non-woven fabric on the surface of the coil comes into contact with the adhesive liquid, the tangential arrangement of the non-woven fabric fibers makes it easy for the adhesive to penetrate. The adhesive liquid enters from the mesh like pores of the non-woven fabric, playing a mechanical riveting role, so that the coil can be firmly adhered to the coil or substrate.
2. Hot melt bonding refers mainly to the hot wedge welding method, which has a better bonding effect.

How to avoid the aging problem of root puncture resistant waterproofing membrane? Let me take you to understand it together.
The root puncture resistant waterproofing membrane is made of a special composite copper base as the membrane base, modified asphalt with added special chemical root inhibitors as the coating material, and polyethylene film, fine sand or mineral particles as the isolation material. In addition to its performance, the root puncture resistant waterproofing membrane also has special chemical root inhibitors added to the modified asphalt, which can effectively prevent plant roots from penetrating the waterproof layer, ensuring the service life of the root puncture resistant waterproofing membrane. The characteristics of the root puncture resistant waterproofing membrane are:.
1. Root puncture resistant waterproofing membrane has a dual function of waterproofing and preventing root penetration. It can withstand PVC waterproofing membrane being penetrated by plant roots and has the ability to maintain long-term waterproofing.
2. The root puncture resistant waterproof membrane not only prevents root puncture, but also does not affect the normal growth and development of plants.
3. Root puncture resistant waterproofing membrane can form a high-strength waterproof layer, as well as the ability to resist pressure water, and has advantages such as puncture resistance, cracking resistance, tearing resistance, and fatigue resistance.
4. Root puncture resistant waterproofing membrane has high tensile strength and elongation, and is particularly adaptable to shrinkage deformation and cracking of the foundation layer.
5. Root puncture resistant waterproofing membrane has excellent high and low temperature resistance, and can be used in hot and cold areas.
6. Corrosion resistance, mold resistance, and good weather resistance.
7. Root puncture resistant waterproofing membrane can be constructed using hot melt method, and the construction party's TPO waterproofing membrane is convenient and the hot joint is reliable and durable.
The application scope of root puncture resistant waterproofing membrane is mainly suitable for waterproofing and root blocking of underground building roofs for planting roofs and greening.
Precautions for construction, packaging, transportation, and storage of root puncture resistant waterproofing membrane:.
1. Construction is not allowed on rainy, snowy, and windy days with winds above level 5. The temperature in the construction environment should not be lower than 0 ℃.
2. The distance between the nozzle of the flame heater and the surface of the coil should be moderate, and the heating within the width should be uniform, with the degree of melting the surface of the coil to a bright black color, and excessive heating of the coil should not be allowed.
3. Protective facilities at the construction site shall be installed, and fire-fighting equipment shall be placed in accordance with regulations.
4. Packaging - Roll packaging with plastic tape.
5. Storage and transportation - During storage and transportation, polymer self-adhesive film waterproof rolls should be stacked separately to avoid direct sunlight and rain. The storage temperature should not exceed 50 ℃, and the rolls should be placed vertically in no more than two layers to prevent tilting or horizontal pressure. Storage period: one year.
1. The distance between the longitudinal hanging points along the tunnel arch is the same as the distance between the anti root puncture waterproof membrane hanging rings. The distance between the hanging ring points on the arch is 85cm, and the distance between the hanging ring points on the side wall is 90cm. In order to ensure the thickness of the poured concrete, waterproof boards are reserved inside the arch to prevent voids from appearing inside the arch.
2. Drill and pre embed plastic expansion pipes and wooden screws at the marked lifting points with a hammer drill.
3. From the center of the arch along both sides of the ring.
4. Adjacent waterproof boards should be laid according to the above method, and a 10-13cm overlap edge should be reserved. The grinding surface should be smooth with liquid roll material.
5. In construction welding, a self-propelled hot melt welding machine is used to weld double welds along the circumferential direction from one side. During the debugging process, the temperature of the hot melt welding machine can be controlled. After each welding, it is necessary to inflate and check. When the pressure reaches 0.1, maintain it at 0.2 MPa for 1 minute to check whether the waterproof plate W weld and waterproof ring are not damaged and the welding quality is good.
6. The grinding width of the anti penetration root waterproofing membrane is 8-10cm, and the width of each weld seam is 1cm. Double seam welding should pay attention to welding at the same time, and there should be no virtual welding, leakage welding, burning or other phenomena. If there is a burning area, repair it with waterproof coils and welding joints. The size of the patch waterproofing board should be determined based on the overlap width greater than 8-10 cm.
