Polypropylene waterproofing membrane has become a common waterproof building material and is increasingly recognized in construction. However, for builders, their lack of understanding of polypropylene waterproofing membrane can lead to incorrect construction, unnecessary losses, and even danger. Now let's take a look at the correct construction method for polypropylene waterproofing membrane.

Roof, kitchen, bathroom, balcony waterproofing.

Material requirements.

The waterproofing membrane used in this project is Shengchang SC-858400g polyethylene polypropylene composite waterproofing membrane, which should have a factory certificate of conformity (appraisal certificate, certification certificate, retest form).

Main equipment.

Electric mixer, iron rod, roller, scraper, iron bucket, broom, small wire, steel tape measure, scissors.

Homework conditions.

The surface of the base layer of SBS waterproofing membrane should be smooth and free of defects such as cracking and sanding. The pipe roots and internal and external corners should be smoothed into arcs or octagonal angles.

The surface of the base layer should have a certain strength, which should not be damaged by people stepping on it. The flashing should meet the design requirements, and the construction environment temperature should not be lower than 5 ℃.

At the edges of the floor drain, pipe root, water outlet, and sanitary ware root connected by the leveling layer, the end should be smooth, the components must be installed firmly, sealed tightly with sealant, and inspected and accepted for concealed works.

In places with poor ventilation, insufficient light, and difficult operation, measures such as ventilation and lighting should be taken during construction.

Operation process.

technological process:.

Grassroots cleaning → detailed inspection and treatment → additional layer for details → waterproof PVC waterproofing membrane layer → water storage test → application of protective layer.

The surface of the base layer must be smooth, sturdy, and free from defects such as sanding, hollowing, and cracking.

The construction of waterproof layer should be carried out in the order of low to high, detail to overall.

The lap length of the coil material should not be less than 10mm, and the lap length of the short side should not be less than 150mm, without defects such as curled edges and hollowing.

Roll up fa ç ade kitchen, with a 300mm flip up for the entrance garden, a 100mm flip up for the balcony, and a 2250mm flip up for the bathroom (calculated from the cast-in-place floor surface of the bathroom).

The cement slurry of the bonding layer should be mixed evenly, and the roll material should be firmly bonded to the base layer.

After the polypropylene waterproof layer is constructed according to the design requirements and the cement mortar has hardened to a certain strength, a water storage test should be carried out. The water depth at the shallow part of the TPO waterproof roll should not be less than 100mm. After 72 hours, if there is no leakage on the waterproof bottom surface, it is qualified. After passing the test, the protective layer construction can be carried out. If there is leakage, it should be repaired. After the protective layer is completed, a second water test should be carried out. After passing the acceptance of relevant personnel, the next process of construction can be carried out.

Product Overview:.

Polymer self-adhesive membrane (non asphalt based) waterproofing roll is a waterproof material specifically developed for pre laid parts of building waterproofing. The roll is composed of polymer sheet, polymer self-adhesive membrane, and anti sticking layer, and is a non asphalt based polymer pre laid waterproofing roll developed to achieve integration with concrete structures.

Under pressure, the polymer self-adhesive film and the cement slurry that has not yet set in the concrete undergo creep, causing the polymer self-adhesive film waterproofing membrane to permeate through the anti adhesive layer in opposite directions, forming effective interpenetrating bonding and huge intermolecular forces. After the concrete solidifies, the gap between the polymer pre laid waterproofing membrane and the structural body is sealed to the maximum extent, completely eliminating water channels.

Product features:.

·Pre laid bonding.

It can bond with the subsequently poured concrete and remain inseparable even after long-term immersion, solving the problem of pre laying (external waterproofing and internal pasting) waterproofing.

·The bonding is reliable and easy to maintain.

The waterproof membrane is tightly bonded to the post poured concrete. If there is any local damage to the membrane, the water will be limited to a very small range and will not flow. Even if there are individual leaks, the leakage points will be consistent with the damage points, making it easy to repair.

·Low base requirements, saving construction time.

The liquid roll material can be used for construction when it is damp or even without leveling the base surface, without the need for primer. It has a high degree of freedom in construction and is not affected by weather. During rainy season construction, its advantages are even more prominent, making it a powerful "weapon" to ensure the construction period.

·Safe and environmentally friendly.

During the construction process, solvents and fuels are omitted, avoiding environmental pollution and fire hazards, and saving resources.

·Excellent physical performance.

Has excellent tensile, elongation, root puncture resistance, weather resistance, and strong adaptability to substrate deformation.

·Drunk and cost-effective.

It can be used together with the post poured concrete structural layer to construct an extraordinary "skin" type strong waterproof system, with high reliability. It can also eliminate the traditional cement mortar leveling layer and fine stone concrete protective layer, saving related costs and low system cost.
