Description Cracking porosity is the most headache because it is the main cause of damage to concrete buildings. Then this high-pressure grouting machine will be able to solve this problem for you. It adopts the chemical grouting method, using mechanical high-pressure power to inject chemical grouting material into concrete cracks, which can fill the pores and provide you with the most stable way to stop water and prevent leakage!   Key Features Not Afraid of Challenges: The wider the crack, the greater the flow rate of the slurry, the deeper it enters the crack, and the better the grouting effect the machine plays, so you can use it with confidence! Multi-functional Use: One machine can satisfy most of your grouting jobs! It can effectively grout cracks of different sizes and states by utilizing different types of grouting solutions. Good Anti-leakage Effect: When water-soluble polyurethane is injected into concrete cracks at high pressure, it extends to all joints. When you inject water, a large amount of carbon dioxide gas is released with the cross-linking reaction, generating secondary penetration pressure. With such high-pressure thrust and secondary penetration pressure, it can serve to fill all the gaps and achieve the purpose of stopping the leakage. High Efficiency: It has a pressure of up to 10000psi and conveying flow rate of up to 0.75kg per minute. Such a large flow rate and high efficiency can save your time.   Good Security: It is equipped with a pressure gauge that accurately displays the amount of pressure when the machine is operating. You need to pay attention to the changes in the pressure gauge during construction, to prevent excessive pressure will be a safety hazard.   Great Durability: This machine is made of iron and aluminum, so you don't have to worry about it being easily deformed. Its pump has also been tested repeatedly to make it more durable and can be used for a long time.   Details Pressure Gauge: It allows you to easily monitor the level of pressure on the machine, which is both safe and convenient.   Dustproof Switch: It has a dustproof design at the switch, which can effectively prevent dust from entering and damaging the switch and prolong the service life of the machine.   Application It can be used in the subway, tunnel, pump room, storage pool, cesspool, underground human defense tunnel, basement garage plugging, cable trench, culvert, dam, power plant dam, acid (alkali) pool plugging, cooling tower plugging, mines, elevator shaft, underground rocks and other places to play the role of seepage prevention, leak prevention, concrete engineering cracks, structural joints grouting plugging, external wall waterproof plugging, etc.   Specification Product Name: High Pressure Perfusion Machine Material: Aluminum, Iron Rated Power: 720W Voltage / Flat Rate: AC 220V/50HZ Maximum Output Pressure: 10000psi Start Again: 7500psi Maximum Pressure of High Pressure Pipe: 10000psi Switching Valve Safety Range: 18000psi Delivery Flow: 0.75 kg/ min ( 1.65lbs/min) Size: 39*20*43cm/ 15.35*7.87*16.93in Net Weight: About 6.2kg/ 13.67lbs Gross Weight: 6.5kg/ 14.33lbs Steps for Use 1.Cleaning: Detailed inspection and analysis of leaks to determine the location and spacing of grout holes. Clean the area to be worked on and remove sediment from the concrete surface to ensure a clean surface. 2.Drilling: Drill a pressure relief hole around the hole with a 14mm/0.551in diameter drilling tool at a 45" drilling angle. Rinse the grouting hole with a washing machine until the grouting hole is clear, then you can proceed to the next step. 3.Buried Port: observe the pressure of the main leak hole. When the water flow is not rapid and the pressure is not large, the grout stopper pin can be buried with a fast-drying plugging agent. After the structure is stable, re-drill the wooden wedge and install the expansion water stop pin so that the grout is completely dense from deep to the surface until all holes and gaps are plugged. 4.Grouting: Test pressure with a high-pressure grouting machine and pour chemical grout into grout holes. Proceed continuously one by one for a single hole. After all the holes are filled, return to the first grouted hole and grout again to ensure maximum pressure. 5.Removal: After 24 hours of grouting and after confirming no leakage, the exposed grout nozzle can be removed or knocked off to clean up the solidified and overflowing grout. 6.Reinforcement: Overall plugging with leak-proof cement-based penetration crystallization pressure resistance sealant, wiping the surface with rigid RG adhesive strips for protective layer reinforcement, and finally polymer JS waterproofing coating, three times the surface waterproofing treatment.   Package Included 1* High Pressure Grouting Machine 2* High Pressure Hoses 2* Combination Gun Heads 2* Pumps 1* Firing Pin 1* Pressure Gauge All Accessories for Assembly
