NPL-S60 Butyl Self-Adhesive Waterproof Membrane

 

Overview:

NPL-S60 Butyl Self-Adhesive Waterproof Membrane with polymer homogeneous sheet as the main material, has low requirements for the base, can be wet-paved, can withstand the construction load and the impact of steel reinforcement, do not need protective layer and so on. After pouring the concrete structure, the coil material and the concrete structure form a permanent organic combination, which effectively improves the waterproof quality. The lower surface is covered with silicone oil anti-adhesion and isolation film, and the upper surface is covered with sand surface, forming a waterproof rolling material that can avoid hitting the protective layer, directly tie the steel bar, and prevent channeling water.

 

Features:

1. Resistance to primary cracking

It is flexible and combines the advantages of PET film with high strength and high extension of cross film to avoid the risk that the water-proof layer will be broken or thin when the base layer is fissioned.

 

2. Excellent bonding performance

The molecular-grade wet self-adhesive layer forms full adhesion with the base layer through the cement paste as medium. Even if there is local damage to the finished products in the later stage of waterproof layer, the overall waterproof effect will not be affected.

 

3. Excellent low temperature performance

Excellent initial viscosity, stickiness, low temperature (-20°C) bonding and other significant characteristics.

 

4. Environmental safety

Does not contain any solvent, environmental protection is safe and reliable.

 

5. To save time

Short construction period, convenient and quick, reduce the construction period, can save more than 3/4 of the construction period, achieve waterproof construction "zero" waiting.

 

6. To save money

The foundation slab concrete cushion is constructed synchronously, the waterproof construction is simple, the 50mm concrete protective layer is omitted, save on the direct cost of the project.

 

7. To save labour

No protection layer, reduce the transport of concrete vehicles, no need for construction personnel, saving a lot of manpower and material resources.

Scope of Application:

Basement and rooftop waterproof projects of industrial and civil buildings, especially suitable for the floor waterproofing of underground projects. Transportation project, such as subway, tunnel, light rail waterproof projects. Waterproofing works for roofing of building basement and planting roof.

  

Construction Process:

1. Base treatment:

a. Cleaning and wetting: the base surface is cleaned by high-pressure water gun, and the dry base surface does not need to be soaked with water.

b. Water cleaning: no water construction, clear the base surface water before construction.

 

2. Preparation of cement mortar:

According to the air temperature and humidity, follow to the water cement ratio of 0.35~0.4, add appropriate amount of water, ordinary portland cement and additives into the batching bucket, and fully mix them with an electric mixer until they are uniform, fine and free of agglomerate particles.

 

3. Slurry exhaust:

Use matching tools to push the surface of membrane and extrude the internal gas, so that the membrane, glue and base are fully integrated.

 

4. Body lapping:

After the adhesive layer reaches the upper strength, tear off the separation film on the lap edge, press the spoke and compact to reach the lap joint of the membrane body.

 

After 1~2 days of laying the membrane, the reinforcement can be bound directly on the surface of the membrane after the mortar reaches the strength, without pouring the protective layer.

 

 

Transportation and Storage:

1. Transportation: the materials shall be placed horizontally, with a height of no more than six layers, and rainproof measures shall be taken, to prevent tilting during transportation, and throwing shall not be allowed during loading and unloading.

 

2.  Storage: when the materials are stored on the outdoor site, the stacking site shall be flat and solid, and the protective shed shall be set up to prevent the sunlight and rain. The indoor storage shall be kept ventilated, and the temperature of membrane storage environment shall not be higher than 50°C.

 

3. Storage period: under the above normal storage and transportation conditions, the storage period is one year from the production date.
