Introduction to Injection Grouting Because injection grouting is cost-effective and easy to install, it can be considered a reinforcement technique. Concrete cracks, voids, or honeycombs can be filled by applying new material to them. Filling cement slurry or applying waterproofing chemicals reduces cracks, voids, and honeycomb in concrete.
The high pressure jet pump uses mechanical high pressure to inject chemical jetting materials into concrete cracks, so that the slurry quickly disperses, emulsifies, expands, solidifies, and finally fills the material body to block the concrete cracks and solve the problem of leakage.
Injection grouting is a process of application of new material in cracks / voids / honeycombs in concrete surfaces. This process is adopted to repair damaged old concrete structural members and strengthen them. Grouting can be done in various methods but injection method is adopted for accuracy and time saving.
Applications of injection grouting system. Injection grouting can be used for filling the cracks, open joints, voids, or honeycombs with material that cures in place to produce the desired results like strengthening a structure and preventing water movement. Its application areas include. Concrete surfaces; Tunnel linings; Stone masonries; Dam
Using a washing agent, flush the grout pump prior to injection and immediately after injection. Flushing the pump eliminates the moisture in the pump and hoses and lubricates the system. Step 6. Flush crack. Flushing the crack will ensure that the crack is wet enough to react the grout when it is introduced into the crack.
Injection can be defined as the introduction of a material with pressure into the ground or a structure for waterproofing and for consolidating voids, cracks and porosity. Generally, the injection can be categorised as Pre Injection and Post Injection. Pre Injection is cost effective in the following: Water Ingress reduction
Fill gaps as well as cracks with pressure injection grouting. Pressure injection grouting, or just pressure grouting, is a catch-all term that extensively covers the highly specialized procedures made use of to spot and also repair a range of problems, tooth cavities or faults in soils or frameworks. In addition to fixing harmed concrete ...

The drill bit should be the same size as the diameter of the injection packer of choice. Spacing for the injection packers can be anywhere between six inches and twenty-four inches, depending on crack size. Flush Holes: …
Concrete-repair techniques vary based on the severity of the damage. If you're filling in cracks, choose a sealant that comes in a tube and apply it with a caulking gun. Simply use a broom or brush to clear the cracks of debris, fill the cracks and smooth the surface to match the surrounding area.
SealBoss 1403 SLV Hydropobic Polyurethane Injection Resin is a super low viscosity, two component polyurethane resin offering outstanding penetration properties, superior strength and durability. At a mixing ratio of 1 to 1 by volume, the mixed product has a super low viscosity of 70 cps. The product is cured chemically and does not need any ...
Below-Grade Waterproofing Injection Grout Restore concrete structures by repairing hairline to 3/4″ cracks. 11 standard colors produce repairs that are less visible. Where to use: Repair and reconstruct brownstone, …
Pressure grouting in concrete is the process by which cementitious grout is pumped under pressure to fill forms, voids, and cracks. In addition to filling cavities or fissures, …
Sikadur® Crack Repair Kit may only be used by experienced professionals. For manual, low pressure injection of horizontal flat and/or vertical static cracksin solid concrete, solid masonry, wood, etc. For gravity feed of …
A hydrophobic polyurethane grout that, when used with the accelerator, is designed to stop water infiltration and fill voids outside structure or joint and cracks in concrete structures. It may also be used …
Grouting is defined as the process in which the injection of liquid grouting material into the concrete under pressure. During the process of grouting, the cracks and pore s in the concrete get filled with the grouting …
This repair kit uses epoxy and polyurethane to fix cracks up to ½-inch thick in basement foundations and concrete walls. This kit includes two tubes of polyurethane for filling the...
The drill bit should be the same size as the diameter of the injection packer of choice. Spacing for the injection packers can be anywhere between …
Pressure grouting in concrete is the process by which cementitious grout is pumped under pressure to fill forms, voids, and cracks. In addition to filling cavities or fissures, cementitious grouting strengthens or further supports existing structures. In this way, it increases the structure's load-bearing capability.
Epoxy injection is an economical method of repairing non-moving cracks in concrete walls, slabs, columns and piers and is capable of restoring the concrete to its pre-cracked strength. Prior to doing any injection it is necessary to determine the cause of the crack. If the source of cracking has not been determined and remedied, the concrete ...
Epoxy resins have relatively high tensile and compressive strengths in relation to concrete, they are generally regarded as 'rigid' materials and widely used for structural repairs by injections of cracks and voids in load bearing reinforced concrete structures or elements. Their low viscosity allows excellent penetration into cracks in the ...
Pick polyurethane injection for effective, low-cost grouting Polyurethane injection grouting is a modern, cost-efficient and also accurate kind of pressure injection grouting that loads openings, fractures, spaces, and cracks quicker and with much less total disruption than a traditional pressure grouting technique.
Firstly clean the area where the concrete crack repair needs to be done. Laitance, dust, paint, skim coat, etc. shall be removed. This shall be done for a width of about 50mm. Generally, the crack repair with epoxy grout will be done by injecting with some pressure. Attach the injection nipples.
Leaking concrete structures can be permanently repaired with concrete crack injection & curtain wall procedures using water-activated polyurethane . Pressure injection of these liquid polyurethane resins forces the material into leaking cracks or behind leaking walls depending on the application. After the polyurethane injection is complete ...
PU injection, also polyurethane grouting or injection, uses expanding polyurethane injection s and crack injection resins to prevent water flowing through voids or cracks. The suitability of polyurethane as a …
When you need to repair a crack in a concrete structure — such as a foundation or wall — from the inside (negative side) of the structure, there are typically two injection techniques and corresponding product technologies that you need to consider — epoxy resin injection and polyurethane chemical grout injection.
