PU / Epoxy Injection Grouting Machine Manufacturers in Pune | Gramcon India
Trusted PU / Epoxy Injection Grouting Machine Suppliers & Dealers in Pune
Gramcon is a trusted PU/Epoxy Injection Grouting Machine Manufacturers in Pune, Suppliers, and Dealers in Pune. We design high-performance grouting systems engineered for structural crack repair, waterproofing, concrete restoration, and sealing applications. Our machines precisely inject PU Resin or Epoxy Resin. We have designed our machines with sturdy materials and specially developed pumps that maintain consistent pressure and resin discharge.
What is PU/ Epoxy Injection Grouting Machine?
It is a pressure-driven system and is employed for the injection of polyurethane resin as well as epoxy resin. It acts as a device that forces resin deeply into concrete. Its operation ensures the strengthening and water-tight paths within concrete.
Types of PU/ Epoxy Injection Grouting Machine
Being reliable PU/ Epoxy Injection Grouting Machine Manufacturers in Pune, we deliver multiple types of systems:
- By Component / Type of Resin
- Single Component – A type, which just mixes the resin and the hardener before the injection, thus a chemical reaction happens in the crack giving the strong bonding and the structural repair.
- Two Component – This type mixes resin and hardener just before injection, ensuring a chemical reaction occurs in the crack for strong bonding and structural repair.
- Fixed Mixing Ratio – The resin and hardener are mixed by the machine in a predetermined, unchangeable ratio which is the main reason for the chemical properties and curing to be always the same.
- Variable Mixing Ratio – The main feature of this type is that one can change the resin to hardener ratio depends on the work giving them freedom to control the viscosity, curing time, and penetration.
- By Power Source
- Manual Pumps – These hand-operated pumps are used for low-pressure, localized repair and precision injection works. We recommend them for quick crack sealing where power supply is not required.
- Electric Pumps – These pumps operate with electric motors to deliver a steady and controlled injection flow. We commonly use them for medium-scale projects due to their portability and consistent performance.
- Pneumatic / Air-Operated Pumps – These pumps run on compressed air and are suitable for wet or hazardous working conditions. We use them for safe and reliable transfer of chemicals, slurries, and deep injection applications.
- Hydraulic Pumps – These high-pressure pumps are designed for heavy-duty and deep injection operations. We rely on them for large void filling and foundation treatment where strong pressure is required.

Features of PU / Epoxy Injection Grouting Machine
Gramcon India operate as leading PU/ Epoxy Injection Grouting Machine Manufacturers in Pune, offer reliable, user-friendly, and long-lasting solutions:
- High-Pressure Injection Performance
PU Injection Grouting Machine provides consistent pressure for pushing resin into a crack and cavity. This aims at ensuring bonding and sealing as well as providing strength and integrity. - Compatible with PU and Epoxy Resins
Grout Pumps can be used with low, medium, as well as high-viscosity fluids. Due to its varied uses, contractors can employ it for waterproofing and restoration works. - Lightweight and Portable Build
Its compact structure makes it convenient for handling at projects. It will be possible to operate at Basement/Underground, Overhead, and Restricted Space without any hassles. - Clog-Resistant Pumping System
Clogging in injection processes is resisted by the machine. Downtime and maintenance are thus eliminated. Productivity and the lifespan of the machine are improved. - Durable and Corrosion-Resistant Components
It is constructed using thick and strong materials that are long-lasting and do not wear and tear easily with water and chemicals.
Applications of PU / Epoxy Injection Grouting Machine
We, as professional PU/ Epoxy Injection Grouting Machine suppliers in Pune, provide solutions for multiple repair and sealing needs:
- Structural Crack Repairs
Injection Grouting System restores the broken concrete beams, floors and columns and by using epoxy bonding, they can make those structures even more capable of carrying heavy loads. - Basement & Water Leak Sealing
PU foam springs into action to instantly plug water leaks, making it the perfect solution for subterranean structures, retaining walls and damp areas. - Tunnel & Bridge Rehabilitation
Repairs cracks caused by stress, wear and tear, and vibrations used to restore integrity and stop water leaks for underground construction. - Industrial Floor & Joint Repairs
It fills floor cracks and joints exposed to heavy loads. Prevents dusting, water entry, and surface weakening. - Water Tank & Reservoir Waterproofing
Pneumatic Injection Grouting Piston Pump injects resins to seal leakage points permanently. This is best for portable water tanks, sewage pits, and inspection.
