Self-adhesive polymer waterproofing roll-roofing manufacturers talk about how to judge the waterproofing roll-roofing good or bad?

1. the quality of manufacturers and products, it is recommended that still field visits to assess the scale of production manufacturers, to see the SBS modified asphalt, modifiers, asphalt materials storage capacity, whether it can meet the requirements of the amount needed for construction projects; asphalt waterproofing roll-roofing production workshop whether to use automatic batching, automatic rolling and equipment operation.

2. Using peel identification

First of all, elastic asphalt waterproofing roll-roofing materials have excellent elasticity, so you can peel the material layer by hand, stretch the asphalt layer, and then let go, if you can stretch for a long time, after releasing can also recover, that the product is modified asphalt do, if the asphalt can not stretch, the asphalt layer is inelastic, the coil can not spring back after breaking by hand, the surface layer cracking, then the surface asphalt layer is easy to remove by hand, the material may be mixed with a large amount of recycled rubber, or waste rubber and recycled rubber mixed with too much modifier, so that the quality of the product may not be guaranteed.

3. identification by fire

Elastomeric asphalt waterproofing roll-roofing additives for SBS modifier, lit by fire on the cardboard, gently stretch upward; poor quality waterproofing roll-roofing additives are waste rubber powder, burned on the cardboard, and then gently stretch upward, not stretch.

Self-adhesive polymer waterproofing roll-roofing manufacturers: construction techniques for waterproofing roll-roofing

1. first need to prepare waterproofing materials and a variety of construction tools, and then the specific construction process, first of all, the grass-roots treatment, construction must be cleaned up before the grass-roots level to ensure that there are no other lumps or debris, and to ensure that the grass-roots level of dryness, moisture content must be maintained within 9%.

2. coil paving process, in the paving process, must understand the size of the paving range, from low to high, ground paving, pay attention to the treatment of complex parts, such as the drainage holes in the corners and other places, to make an extra layer in these complex parts to prevent water leakage affects daily life.
