What affects the waterproofness of concrete?

Water resistance is an important characteristic of concrete, indicating the ability of the material to resist water pressure. The water resistance class of concrete depends on which structures concrete is suitable for.

The water resistance of concrete directly depends on the quality of the cement used, the ratio of dry material and water in the concrete mixture, as well as the conditions of concrete solidification and strength gain.

At the same time, the water resistance of concrete is actively influenced by additives used in the mixing process. Thus, the use of the Teknomer 120 hydrophobic additive allows you to pour durable waterproof concrete, significantly increasing the initial grade of the waterproof mixture.

The Teknomer 120 additive is added directly to the concrete mixer and kneaded for 3-5 minutes along with the rest of the concrete components. The ready-to-use composition in an amount of 2-3% by weight of dry concrete is easily dissolved in the concrete mixture. A small amount of a hydrophobic additive does not affect the overall proportion, at the same time it increases the strength of the finished concrete and its ability to withstand water pressure on the structure.

In order for the Teknomer 120 hydrophobic additive to work as efficiently as possible in finished concrete, it is necessary to follow several simple but important rules when solidifying a poured reinforced concrete structure:

• first of all, it is worth working with a hydrophobic mixture exclusively at positive temperatures - in the range from 5 ⁰ C to 35 ⁰ C
• next, it is necessary to protect fresh concrete from direct sunlight, strong gusts of wind and temperature changes until it completely solidifies

Compliance with these simple rules, combined with the proportional addition of a hydrophobic compound, has a qualitative effect on the water resistance of the finished concrete. Increasing the water resistance of the concrete mix with the help of the Teknomer 120 hydrophobic additive is a simple, profitable and modern solution for objects requiring increased protection from the aggressive effects of water and moisture.
