How to cover old concrete for strengthening

Concrete is widely used in construction due to its strength and durable properties. It can be used to create foundations, walls, ceilings, stairs, roads, bridges, tunnels, swimming pools and many other structures.

Due to its versatility and accessibility, concrete is one of the most common materials in modern construction, and is also widely used in the production of concrete products, such as concrete blocks, slabs, curbs and other building elements.

However, over time, the concrete begins to crumble, dust, cracks, chips appear. At this stage, it is extremely important to strengthen the old concrete screed, because otherwise, the structure will lose strength — which means simple repairs will not save. Today we will talk about the materials used to strengthen old concrete in domestic premises, warehouses, hangars and other similar buildings.

TOP materials for concrete reinforcementThe modern construction market offers many ways to strengthen old concrete.

As building materials, experts recommend using such:

Teknoser Lityum is a lithium-based concrete strengthener that is used to strengthen concrete structures. It consists of lithium silicate and special additives that interact with the mineral components of concrete, forming new, stronger compounds. The use of the Teknoser Lityum hardener makes it possible to increase the strength of concrete, resistance to abrasive loads and mechanical damage. It also increases resistance to aggressive chemicals, corrosion and cracking. Teknoser Lityum can be used to strengthen concrete structures in various fields, including the construction of buildings, infrastructure, roads, bridges and tunnels. Its use is especially recommended in conditions of high humidity, contact with moisture and seawater, as well as in areas with high temperature and heavy precipitation. One of the advantages of Teknoser Lityum is its fast solidification time, which makes it possible to complete the work on strengthening concrete structures faster.
Another high—quality hardener is Teknoser Sodyum, which consists of sodium hydroxide and other chemical additives. They cause an increase in the strength and resistance of concrete to damage. One of the advantages of Teknoser Sodyum is its cost-effectiveness, as it can be used in smaller doses than other hardeners. It should also be noted that it does not contain substances harmful to health and is an environmentally friendly material.

Teknocila 300 is a two—component polyurethane-based varnish that is used to protect and strengthen concrete surfaces. It is a transparent material that forms a solid film resistant to aggressive environments, ultraviolet rays, abrasive particles, chemicals and mechanical influences. The use of Teknocila 300 varnish can significantly increase the resistance of concrete surfaces to damage, increase their service life and facilitate the cleaning and maintenance process.
The varnish can be used on various objects, including industrial and commercial buildings, parking lots, warehouses, shops, airports, terminals, sports grounds. One of the advantages of Teknocila 300 is its high resistance to abrasive wear, as well as resistance to high and low temperatures, humidity and ultraviolet radiation. In addition, the varnish has good adhesion to the concrete surface and is a chemically resistant material.
