What is Chemical Injection?

Unlike conventional insulation systems, it perfectly prevents the contact of water and concrete. ​Chemical Injection System Application; It is the process of injecting structural liquid materials into the cracks in the concrete or rock floor with the help of an injection pump (providing the necessary injection pressure) and packer.

Purpose of Chemical Injection

        This application system, especially as an important part of the civil engineering field; It is widely used for ground consolidation and filling, sealing and filling in a wide variety of areas such as subway constructions, tunnel constructions, highways, dams, pools and parking lots. The issue of eliminating water leaks, which is frequently encountered in underground structures, tunnels, elevator shafts, power plant rooms, garages, parking lots, reservoir tanks, can only be eliminated with the Polyurethane Injection method.

       The material similar to the fluidity of water is injected into the concrete with a pressurized machine. The material seeps into the cracks and spaces in the concrete where water enters, compresses under pressure and freezes within seconds. After the material is cured, it prevents water penetration into the concrete since it does not deteriorate or dissolve with any external intervention. It saves the concrete and the iron reinforcement inside from the negative effects of water. (We recommend you to review our OneShot Macro Synthetic Fiber Reinforcement product, which is used instead of steel mesh and steel wire reinforcement.)

Properties of Injection Chemicals

       These are the processes applied for the purposes of filling the gaps between the rocks, providing temporary support and creating a solid ground, especially in environments such as underground mines and tunnels. With this technique, in underground environments, whether rock or soil, the gaps and cracks between them are sealed and durable.  

        One of the most important features of Chemical Injection systems is that they can enter into a chemical reaction with water in the ground and turn into a rock-hard form depending on the purpose of use. Moreover, they gain a durability that can maintain the strength of the ground even against high energy seismic movements such as earthquakes and protect the structure. There are also products that can react and foam in environments where water is not available. Single-component, two-component or even three-component products are available. These components are used to change the curing rate of the product or to initiate its reaction. They have the ability to stop the flow in a short time, even in environments with high water pressure.

To summarize some of the features of Injection Chemicals:

 

  • Activation in wet and humid environments,

  • Adjustable reaction time,

  • Ease of application,

  • Sealing on moving floors,

  • Having products that are suitable for drinking water,

  • Applicable at low temperatures,

  • High compressive strength,

  • Applicable even in pressurized water outlets.

Usage Areas of Chemical Injection

       Chemical Injection Systems have a wide range of applications.  Especially with the developments in the chemical industry, application technologies have gained many innovations. Injection systems also take their share from these developments in every sense.

        Injection Chemicals:

  • Stabilization, ground control, sealing and repair in tunnels

  • Chemical filling in the tunneling and mining industry

  • In subway tunnels

Chemical Injection Application

As FMY Chemistry; Our team of engineers, who are experts in their field and have hundreds of successful application experiences, make chemical injection applications with our products that have proven their quality. So how is the injection process done? ​​

  1. First of all, the surfaces where the water comes from and where it can come are determined by the examination made by our expert field engineers.

  2. Then, the most suitable FMY Chemistry Injection Chemical to be used according to the ambient conditions is determined.

  3. Application is usually done by means of pneumatic (air powered) or electric pumps.

  4. Holes are drilled with the help of a drill to mount the injection dowels (packer) on the surface to be injected, at equal intervals and at an angle of 45 degrees with the surface.

  5. Air is pressed into the drilled holes, and the concrete dust inside is cleaned, sealed steel packers are nailed and the assembly is completed by tightening.

  6. Although it varies according to the material to be injected; It is essential that the material is shaken well before the application or kept at the appropriate temperature for 24 hours beforehand.

  7. Pump selection is made according to the mixing ratio or the number of components.  

  8. In order to make injection, nozzles are attached to the packers and the chemical injection application is started with the help of the pump.

  9. In order to control and verify that the injection is successful, the injection process is continued until chemical material comes from other packers, drilled guide holes or cracks. In this way, it is understood that all the cracks have been filled and the operation has been carried out successfully.
