The advantages of chemical grouts

  1. High pressure (generally up to more than 20Mpa) , stable and reliable, the chemicals materials can completely permeate the deep micro cracks of the concrete structure; Perfect waterproof effect
  2. Grouting technology is mature, stable quality, resistant to chemical corrosion, non – toxic after curing, environmental protection, permanent waterproof.
  3. The construction process is simple and easy to operate. The construction is fast, the water stop effect is instant. Low labor intensity, and the construction efficiency is 5~10 times compared to the traditional construction method.
  4. The construction is not limited to season and weather, and can be used for various projects, including maintenance, emergency repair and drinking water project. low construction cost, economic benefit

What is chemical grouts technology?

Introduction to chemical grouts technology

Concrete building crack is the main cause of concrete building damage, crack leakage is the most headache problem, because the cracks inside the concrete is completely ruleless. The general traditional plugging method is gouging the crack or leakage, and make surface plugging, but the result is here is blocked the other places begin to leak. Because the water  in the internal cracks is moving irregularly, then seepage from the weak part of the concrete.

Chemical Grouts generally is inject chemical materials to the cracks of its structure  by high pressure injection grouting machine and injection packers so as to achieve the purpose of waterproof, plugging, reinforcing and strengthening. It is often used to repair deep cracks in concrete structure. According to the grouting pressure and speed, it can be divided into high pressure quick grouting method and low pressure slow grouting method.

OPU & WPU

High-pressure chemical grouts technology is using the injection pumps to generate the continuous high pressure , inject the chemical liquid into the cracks of the concrete, and completely squeeze out the water in the cracks, and completely fill the gaps, so as to achieve the purpose of water stop.
