 Seven core advantages of the product
01 Beautiful color, smooth road surface
02 Adhesive performance Strong heavy load road does not break
03 Waterproof and anti-freezing, to solve the problem of large temperature difference between day and night in the north, and freezing and thawing of rain and snow in winter
04 Compression and wear resistance, better service life than ordinary concrete
05 After repair, traffic will be opened 2 hours to facilitate people to travel and relieve traffic pressure
06 Non-toxic environmental protection, acid, alkali and chloride ion snow melt agent corrosion resistance
07 Energy saving and environmental protection, there is no need to knock down all the old roads, and the cost is 30% less than the traditional process
Construction regulations

Matters needing attention
one This repair method is limited to use when the foundation of the concrete panel is stable, if the panel has appeared more serious misalignment. For emptying, it is recommended to drill holes and press the pulp to flatline and then strip repair.
2, the operating surface should be thoroughly cleaned with high pressure water gun, no floating ash.
3. The operating surface should be fully wet until no more water seepage.
4. Before paving, the patching surface must be thoroughly washed clean, wet but no open water.
5, as far as possible to use a blender to stir the repair material, must control the water-cement ratio, the stirred repair material shall not appear bleeding.
6. No construction in rainy weather or below zero temperature.
