High Pressure Grouting Machine, injection pressure can reach 70Mpa(8000-10000Lb), can inject into above 0.02mm hairline cracks.Transferable material suction method: Besides traditional pour material method,this machine can change to use hose suction method to feed-in material,which can save the pouring material time and material.Except while installing this rig,need to use cleaner to clean up material feed-in system and suction hose right the way, to avoid chemical dried caused inside blockage inside. The high pressure injection machine can produce high injection pressure,deliver the chemical to the center of wall crack,the chemical diffuse from center to all direction.The chemical fast react with water and harden to plug up the crack permanently and rech water stop effect surely.This constructing method use high pressure injection machine, injecting high pressure,big flow,thus can stop the water immediately. Especially for stop the big running water, this method has its magic part.Its inject point is from the center of the structure's crack, so it is effective. It is very fast and efficient, especially for the cracks that is over 40cm thickness' concrete wall.
