Waterproofing membrane sampling standards, waterproofing membrane sampling standards and quantities

There are many kinds of waterproofing membranes, and the sampling standards generally have requirements in the standard, and sampling should be carried out in strict accordance with the requirements of the standard.

Each material is sampled differently. Let's look at the sampling criteria. Modified asphalt waterproofing membrane.

Polyvinyl chloride (PVC) waterproofing membrane and chlorinated polyethylene anti-water membrane: the same manufacturer, the specification does not exceed 5000m2 for a batch, and the crack is almost any roll, from the end. Cut about 3m at 300mm as a sample.

3.EPDM.

Membrane and rubber-based rubber waterproofing membrane: the specifications of the same manufacturer shall not exceed 5000m2, and each batch shall take 2m2. Rubber waterstops.

2m long, the same manufacturer and the same specifications. 4.Modified asphalt polyethylene tire waterproofing membrane:

A batch of the same specification not exceeding 1000m2, one roll per batch. 5.Chlorinated polyethylene-rubber blend waterproofing membrane:

No more than 250 rolls of the same specification are a batch, and when the appearance is qualified, one roll will be drawn from each batch. 6.Asphalt composite tire flexible waterproofing membrane:

A batch of the same specification not exceeding 1000m2, one roll per batch. 7.Self-adhesive rubber asphalt waterproofing membrane:

The same specification is not more than 5000m2, and each batch of polymer waterproof membrane adhesive is extracted: a batch of no more than 5 tons of the same specification, each batch is 500ml.

1. The membrane and supporting materials used in the membrane waterproof layer must meet the design requirements. Inspection method: check the factory certificate, quality inspection report and on-site sampling re-inspection report.

2. There shall be no leakage or water accumulation in the waterproofing of the membrane.

Test method: after rain or drenching, water storage test.

3. The waterproof structure of the membrane waterproof layer in the gutter, gutter, cornice, water drop, flooding, deformation joint and protruding layer pipeline must meet the design requirements.

Inspection method: Observation inspection and inspection of concealed engineering acceptance records.

4. The lap seam of the waterproof layer of the membrane should be firmly bonded (welded) and tightly sealed, and there should be no defects such as wrinkles, warping and bubbling; The end of the waterproof layer is bonded and fixed with the base layer, and the seam is tightly sealed and the edge is not warped.

Test Method: Observation and Inspection.

5. The spreading material and the light-colored paint protective layer on the waterproof layer of the membrane should be spread or painted evenly and firmly bonded; Cement mortar, blocks or fine stone concrete protective layer and membrane waterproof layer should be provided with an isolation layer; The rigid protective layer and lattice seam retention should meet the design requirements.

Test Method: Observation and Inspection.

6. The exhaust duct of the exhaust roof should be vertically and horizontally connected and should not be blocked. The exhaust pipe should be installed firmly, in the correct position, and tightly closed.

Test Method: Observation and Inspection.

7. The paving direction of the coil should be correct, and the allowable deviation of the lap width of the coil should be -10mm.

Inspection Method: Observation and Measurement Inspection.

Membrane waterproof layer roofing construction technology.

1. Hot adhesive method: the construction method of bonding the coil and the base layer and the coil and the coil by using Therma Grease.

2. Cold bonding method: the method of using adhesive or mardiol to bond the coil and the base layer, the coil and the coil, without the need for heating construction.

3. Self-adhesive method: the construction method of using waterproof membrane with self-adhesive adhesive does not require thermal construction or cementing materials.

4. Hot melt method: the construction method of using a flame heater to melt the hot melt adhesive on the bottom layer of the hot melt waterproofing membrane for bonding.

5. Welding method: the construction method of lap bonding of waterproof membrane by using hot air welding gun.

1. The waterproof layer of the membrane and its corners, deformation joints, wall pipes and other detailed practices must meet the design requirements; 2. The base layer of the membrane waterproof layer should be firm, and the base surface should be clean and smooth, and there should be no hollowing or loosening; 3. The lap seam of the waterproof layer of the membrane should be firmly bonded and tightly sealed, and there should be no defects such as wrinkles and warping; 4. The allowable deviation of the lap width of the coil is -10mm.

What are the types of waterproofing membranes?

1. Asphalt waterproofing membrane.

Asphalt waterproofing membrane is mainly made of asphalt and kerosene asphalt, as well as petroleum asphalt. And there are many types, including asphalt gas stations, water emulsion asphalt, and rubber asphalt coatings, which themselves have relatively strong waterproof and anti-corrosion, and are durable to use.

2. Rubber and plastic waterproofing membrane.

This fiber allows the coil to use butyl rubber and polyurethane and other substances as raw materials, and the waterproof membrane, waterproof membrane, and some waterstop tapes are made of waterproof membranes, which have good tensile strength, good elasticity, and good elongation. And the anti-sleeping habits and weather resistance are also worthy of praise, and the use is strong and firm.

3. Cement-based waterproofing membrane.

When in use, the cement has a relatively intact waterproof, moisture-proof, seepage-proof effect, and can also act on underground engineering, using these waterproof membranes to plug leaks, the effect is unusually perfect.

4. Metallic waterproofing membrane.

Thin steel plate, profiled steel plate, galvanized steel plate can be used as a roof panel, the role is waterproof, and the thin steel plate can also be used in the basement and other large areas of underground buildings, the waterproof effect is very good, there will be no moisture, leakage, a more common decoration mode when used on the building.

Summary: The above is about the relevant content of the quality acceptance specifications of waterproofing membranes, I hope it will be helpful to you! There are many specifications for the quality acceptance of waterproofing membranes, so different aspects should be considered in the acceptance of waterproofing membranes.

In our daily life, we will inevitably encounter some acceptance work of waterproofing membrane, so what is the standard for the acceptance of waterproofing membrane?

1. What are the acceptance criteria for waterproofing membranes?

1. When we accept the waterproof membrane material, we must see whether there are deformed gaps at the corners of the waterproof membrane and whether some details such as wall pipes meet the qualified requirements.

2. Secondly, whether the base layer of the waterproofing membrane is firm or not, we must check these quality problems.

3. There is also the base surface of the waterproofing membrane, whether it is kept smooth and clean, and there is no hollowing or loosening, if there is such a situation, then the quality of the waterproofing membrane is not standard.

4. In addition, whether the lap seam of the waterproof membrane is firmly connected, in this case, its sealing must be ensured, and there must be no wrinkles If there are these defects, then the quality of the waterproof membrane must not be standard. It is also necessary to check the thickness and width of the waterproof membrane, the general width deviation can not be higher than 10 mm, if it is higher than 10 mm, then the quality acceptance of the waterproof membrane is also unqualified.

2. What are the precautions for using waterproof membranes?

1. Yefu should see the weather clearly when using the waterproof membrane, and never carry out membrane construction when it rains.

2. The waterproof layer of the membrane must be done well, the leveling quality must meet the requirements, and the specified degree of dryness must not be too wet, so as to prevent the problem of falling off in the later stage.

The above is a summary of the relevant content and information about the acceptance standard of waterproofing membrane, I hope it can help you.
