National Construction Department and Environmental Protection General Bureau .The product is characterized by its easy construction ,shock resistance, aging resistance elongation resistance ,ultra-violet light resistance and high bond strength .
When surface dry (in 5-10minutes ),wrapping can be done .
After the quality inspection is done .the pipes can be put put back into the ditch and be buried .
