Processing steps

  • Using grinder bar to mill the "v" shape of crack, then press the base wall with manual or automation syringe.
  • Injection of seal glue 1036A/B into the "V" shape of crack to fill the crack.
  • Using cylinder to inject epoxy resin and hardener 2100A/B into base wall, after curing of seal glue, take advantage of its own shrinkage of base wall, the strength of wall structure will be enhanced 5 times than original wall structure.

C.Glue of Heat insulation and water proof roof

Sunlight, air, water are 3 most important substances to human in our daily lift. However, ulstraviolet from sunlight, the oxidation from the air and the moisture from the water cause the building rusty and flaky. Hence, it is important to improve th building with high performance of epoxy resin, which can reststance of heat insulationand waterproofing

Processing steps

1.Floor treament: It must keep the plain floor free from dirt. It is necessarilly to rub off the residual particle such as grease and moss. The floor must always dry and no water before implementing epoxy flooring.
2.Heat insulation and water-proofing treament:
  • Base glue:To enhace the bonding of cement and top glue (dosage 0.3kg/m2). Mixing 2040A and hardener 2040B with the ratio of 2:1. Then spread onto the cement by using brush or roller.
  • Top epoxy resin : The purpose is to heat insulation and water proof. (Dosage 0.8~1 kg/m2). Mixing 1016AT and 1016BT completely and coating on the surface of the base glue. It must be spread on carefully in order to get a smooth surface. It allows to step on after 2 days.

D.Reinforcement of carbon fiber and glass fiber

  • Characteristic
  • Light loading : The weight is 1/5 of the weight of steel.
  • Excellent elongation ability : The elongation ability is 10 times better than elongation ability of steel, suitbale for reinforcement of MRT station and viaduct.
  • Durable : Able to stand for the sunlight for about 30 years.
  • Ease to work : Short working time and no maintenance needed.
  • Good physical properties.
  • The reinforcement of composite materail i.e. carbon fiber and glass fiber

F. Reinforcement of building

Attentions :

  • Pre cleansing of the wall.
  • Using 2040A/B as the protection coating, primer coating
  • Using non-sagging paste for sealing and reinforcement of building, e.g. for heavy leaking use the light sand paste in heavy leaking, use the heavy sand paste in light leaking. (i.e. 1351A/1351B)
