Cracks, potholes, destroyed concrete screeds, worn industrial floors and parking lots require not cosmetic, but structural repairs that can withstand constant high pedestrian and mechanical loads.

A professional solution for restoring such surfaces is Teknogrout 350 - a bulk, non-shrinking repair mixture with rapid strength gain, designed for professional repair of concrete and reinforced concrete structures.

Teknogrout 350 repair mixture and why professionals choose it

Teknogrout 350 is a dry mix based on special cement and fine-grained aggregate, which when mixed with water forms a flowable self-leveling mortar. The material easily fills cavities, cracks and potholes, providing high adhesion to concrete and metal.

The key advantage is the lack of shrinkage. This means that after hardening, the material does not “peel” from the base, does not crack, and does not lose strength even in difficult operating conditions.

Where is the non-shrinking repair mixture Teknogrout 350 used?

Teknogrout 350 non-shrinking concrete repair grout is designed for horizontal surfaces and is used where conventional repair mortars cannot withstand the loads:

  • structural repair of horizontal concrete surfaces;
  • repair of concrete and reinforced concrete elements;
  • repair of floors of hydraulic structures, tunnels, bridges, ports;
  • restoration of industrial floors, logistics centers, warehouses;
  • repair of parking lots, parking lots, road surfaces and sidewalks;
  • grouting for machine tools, supports, columns, fences, thrust bearings;
  • repair of cracks, potholes and concrete screeds;
  • creating wear-resistant and waterproof coatings.

 

Due to its resistance to chlorides, sulfates, and oils, Teknogrout 350 is suitable for facilities with difficult operating conditions.

Main advantages of Teknogrout 350 concrete repair mixture

✔ non-shrinking composition — stable surface geometry after hardening; 
✔ high compressive strength — 60 N/mm²; 
✔ rapid gain of strength and putting the surface into operation after 24 hours; 
✔ high adhesion to concrete and metal; 
✔ waterproof and high wear resistance; 
✔ does not contain components that cause corrosion of reinforcement; 
✔ application thickness — from 10 to 75 mm per layer.

Preparation of the substrate before applying the bulk repair mixture Teknogrout 350

Before repairing a concrete floor using Teknogrout 350 working repair mortar , the base must be properly prepared:

  • weak and damaged areas of concrete must be removed;
  • clean the surface from dust, dirt, oils and foreign materials;
  • cracks and seams should be filled in a U-shape (in a section of width and depth of at least 20×20 mm);
  • For maximum adhesion to concrete and reinforcement, it is recommended to first use an adhesion promoter and corrosion inhibitor - the Tekno AD mixture.
  • moisten the surface well;

How to properly prepare Teknogrout 350 repair mortar

  1. Pour 3–4 liters of clean water into a clean container.
  2. Gradually add 25 kg of Teknogrout 350 dry mix, stirring constantly.
  3. Mix with a low-speed mixer (400–600 rpm) for 3 minutes until smooth.
  4. Pause for 2 minutes and mix again for 30 seconds.

IMPORTANT! It is forbidden to add water after the start of mixing. The pot life of the finished solution is up to 30 minutes.

Important restrictions and recommendations when using Teknogrout 350 non-shrink repair mixture

  • do not use on frozen or wet surfaces;
  • do not use on smooth surfaces without preparation;
  • do not mix by hand or use gravity concrete mixers;
  • maintain a temperature range of +5 to +35 °C;

If you need a professional non-shrinkage concrete repair compound that combines rapid strength gain, high wear resistance and durability, Teknogrout 350 is the optimal choice for industrial, infrastructure and commercial facilities with intensive use.
The key advantage of the material is the ability to put the repaired surface into operation after 24 hours. This is critically important for production facilities, warehouses, parking lots, logistics centers and transport infrastructure, where downtime means direct financial losses.
Teknogrout 350 does not just eliminate cracks, potholes or damaged areas. It restores the load-bearing capacity of concrete structures, ensures stable geometry without shrinkage, resistance to mechanical and chemical loads and a long service life of the coating.
By choosing Teknogrout 350 , you get a reliable engineering solution that allows you to perform repairs quickly, efficiently, and with minimal downtime of the facility - exactly as required by modern construction and industrial standards.
