PRODUCT DESCRIPTION
What is polymer grout? And how is its formulation?
Polymer grout consists of two parts of polymer resin and cement mixture with high strength and special granulation with sugar silica sand, with the best lubrication properties.
What is the maximum thickness for polymer grout?
For polymer grout, the minimum thickness should be about 25 mm and the maximum thickness should be about 80 mm.
How to calculate the volume of grout?
Calculating and estimating the required amount of grout is very important. For this purpose, Afzir Retrofitting Company has designed the following online calculator tool to facilitate the process of calculating the required amount of grout, which suggests the required amount of grout according to the implementation conditions of your project.
The purchase price of polymer grout
The price of polymer grout with fibers (FCG™ code) is calculated as the price of each kilo of grout and can be supplied by the kilo or bag. You can contact our experts to know how to buy and the price of reinforced cement grout.
The difference between epoxy-based grout and polymer-based grout
- Epoxy-based grouts have higher chemical resistance than polymer grouts.
- Epoxy grout is used for plates that are exposed to dynamic loads, but polymer grout is used for plates that are exposed to static loads.
- Polymer grouts have very low tensile strength, but epoxy grouts have high tensile strength. For this purpose, epoxy grout can be used to transfer tensile loads to the foundation.
- Polymer grout can be applied at a temperature equivalent to 200. But epoxy grout can be used at a temperature lower than 55.
- Epoxy grout is more efficient than polymer grout.
- The compressive strength of epoxy grout is 50 to 100% higher than polymer grout.
- Epoxy grout is more efficient than polymer grout.
How to choose the right grout
Grout is selected depending on the type of project conditions. The influencing factors in choosing the type of grout are described as follows:
Ambient temperature
polymer grout can be used at a maximum temperature of 200. But epoxy grout can only be used at a temperature below 55.
The type of load applied to the plate
The load applied to the plate can be static or dynamic. Static loads are applied permanently and dynamic loads are applied dynamically. In fact, it is better to say that static loads are loads that remain fixed in place. But dynamic loads are time-varying and change frequently, like the load of a car. Therefore, the type of load applied to the plate is effective in choosing the type of grout. Polymer grout works better than epoxy grout in places where the load is applied statically. But in places where the load is applied dynamically, epoxy grouts perform better than polymer grout due to their lack of rigidity.

- In this section, we discuss the grouting recipe.
Minimum execution thickness: 25 mm.
Maximum execution thickness: 100 mm. - In the gravity grouting method, it is recommended that the minimum thickness should be about 25 mm for a flow length of 300 mm. For every 300 mm of additional run length, the thickness should increase by about 13 mm to a maximum of about 100 mm.
- Grouting is not recommended at a temperature lower than 5 degrees Celsius. (The suitable temperature for grouting is more than 5 degrees Celsius.)
How to prepare the substrate
The concrete surface must be clean, healthy and free of water and grease as much as possible, and damaged concrete must be removed.
You can use approved chemicals to clean the concrete surface.
mixing
Open the bucket and remove the sheet, pour the hardener (part B) into the resin bucket (part A) and stir the mixture with a spatula or hand mixer until it becomes a uniform color.
You can also use a low-speed mixer and a high-speed mixer, provided that mixing does not create air bubbles in the ingredients. Excessive mixing can reduce the quality of grouting.
Implementation of grouting
The mixed grout should be continuously poured from one side to eliminate air entrapment.
A continuous flow of grout is essential
Sufficient grout must be available before starting
When grouting, pay attention to the pot life of the product.
- Avoid skin or eye contact. In case of contact, wash skin with soap and water. In case of contact with eyes, flush with water for 15 minutes.
- Before using cement grout, read all the precautions, specifications and properties listed on the product.
