Polymer Modified Traffic Bearing Repair Mortar

High Viscosity High Traffic Surface Concrete Repair (TRM™400 Code) is a fast-setting, high-flowing repair product and a bed mortar that contains sulfate-resistant Portland cement, hydraulic primer, Fine-grained sands, specially selected polymer fibers and special additives that improve durability and uneven dry shrinkage. Traffic bearing repair mortar combines with water to form a plastic/flowable mortar that is easy to apply by hand. This product can be applied in thicknesses of 10 mm to 150 mm.

Application Instructions

Preparation of the substrate

The concrete must be completely sound, cured and clean for full adhesion. All traces of dust, oil, etc. must be removed from the surface of concrete and mortar.
Damaged or contaminated concrete must be removed to obtain an even surface. Cleaning methods without impact/vibration such as shot blasting or sand blasting with strong water pressure are recommended. Gradation should be clearly visible on the concrete surface of the structure after surface preparation.
Cut the edges of the repair surface to a depth of at least 10 mm. If the steel reinforcement is visible, clean it at least 2 degrees. Make sure the back of the bar is clean as well.
Damaged armatures or sections of them that are lower than the safety level need to be replaced due to structural reasons. Ensure a 2 cm cover when additional rebar is installed. Although the concrete restorer of high-traffic surfaces can be applied at temperatures of minus 10°C, the substrate must be at least 0°C and at most 30°C. Frozen substrates must be de-iced immediately before applying the concrete repairer of high-traffic surfaces. Ensure that any metal parts eg rebars and frames are defrosted above the freezing point. Try to keep the temperature the same during installation and curing.

Mixing procedure

It is strongly recommended that intact packages be used for compounding and damaged and opened packages should not be used.
First, pour the potable water into the mixing bowl and then slowly and continuously add about 2/3 of the high-traffic concrete repair powder (TRM™400) to the water. Continue stirring for at least 1 minute. After 1 minute, pour the rest of the powder into the mixture and continue stirring until a uniform mortar is obtained.
Mix the high-traffic concrete repairer (TRM™ 400) with a suitable mixer. The mixing time is about 3-4 minutes until a uniform plastic consistency is obtained. Use only clean, unpolluted water.
The amount of water required for the mixture:
3.1 to 3.6 liters per 25 kg package is required for plastic consistency.


Concrete substrates and other metal surfaces that come into contact with concrete repair for heavy traffic surfaces (TRM™ 400) must be de-iced.
The prepared substrate should be soaked 24 hours before applying concrete on high traffic surfaces or at least 2 hours before.
For optimal handling of the temperature during the installation of concrete, high-traffic surfaces should be between -10 and +30 degrees Celsius.
Pour the high-traffic concrete product (TRM™ 400) on the pre-moistened surface in an abundant amount to create compaction. In order to ensure optimal adhesion, apply a layer of grout of the product to the pre-soaked substrate before repair work. Pour high-traffic concrete on the surface. In working conditions below -10 degrees Celsius, cover the product with insulating materials or dry cloth until it hardens completely. It is not recommended to use this product in temperatures below -10 degrees Celsius.
About 78 packages are needed to produce one cubic meter of mortar. A 25 kg pack produces about 12.9 liters of mortar.


Tools and mixer should be cleaned with water after use. The processed materials should be cleaned mechanically.


Complete processing is achieved in 28 days after installation at a constant temperature of 23 degrees.

Working time

20 minutes at 20 degrees Celsius (ambient and substrate temperature)

Frequently Asked Questions

What type of mortar is used to repair high-traffic concrete surfaces with high viscosity?

It is a fast-setting, high-fluidity restoration product and a bedding mortar that includes sulfate-resistant Portland cement, hydraulic primer, granulated sand, specially selected polymer fibers, and special additives.

What is the effect of adding an additive on the repair performance of concrete on high-traffic surfaces?

Special additives improve durability and unmatched dry shrinkage.

Why does surface concrete repairer have minimal cracking?

This type of repair has a reduction in mortar cracking due to the contraction of PAN fibers in the mortar.

For what surfaces is floor concrete repair mortar used?

Floor concrete restorer is used for staining horizontal repair areas, staining sloping areas and optimizing traffic management.

What should be the amount of water used to combine with concrete repair powder?

An appropriate amount of clean water without pollutants should be used to reach the desired plastic consistency.

What should be the temperature during concrete installation for optimal performance?

The temperature during concrete installation of high-traffic surfaces should be between -10 and +30 degrees Celsius.

For what thicknesses is floor concrete repair mortar used?

Floor concrete restorer can be applied in thicknesses of 10 mm to 150 mm.

After how many hours can the floor repair mortar be used?

The floor restoration mortar can be used 2 hours after its implementation for all traffic levels.

Why is floor concrete repair mortar used for surfaces?

Because it shows high swing against dynamic and static loads.

How can you cover a thicker floor using concrete repair mortar?

The thickness of the work can be increased by adding sand.
