Purpose

Water-repellent, pore-sealing admixture "Hydrophobic Admixture H 3" – TM “MTC Concrete is a hydrophobizing, water-reducing admixture used in the production of hydraulic concrete to reduce water absorption of concrete bases in above-ground, underground, and civil engineering structures. H 3 – MTC Concrete can be used without the addition of plasticizers.

H 3 – MTC Concrete admixture is also used:

  • in the production of decorative paving elements;

  • to improve the appearance and physico-mechanical properties, especially for products with high surface quality requirements.

The use of this admixture is recommended at temperatures from: -10 °C to +30 °C.

Properties

The H 3 – MTC Concrete admixture causes chemical modification of free calcium ions and the formation of a hydrophobic coating in the capillary pores, providing the following benefits:

  • reduces water absorption;

  • enhances water-repellent properties;

  • promotes hydrophobization of the capillary pore system;

  • increases frost resistance and resistance to deicing salts;

  • prevents the formation of calcium efflorescence on the surface;

  • ensures smooth and even concrete surfaces.

Dosage

Recommended dosage: 0,5 - 1,5% of the cement mass.

The optimal dosing depends on the required properties of the concrete and is determined experimentally.

Application

Important! Do not add to dry mix!

Frequently asked questions
What raw materials are used in the production of this product?

Long before launching our own production in 2007, the MTC Concrete team began a thorough search for the highest quality raw material suppliers. Thanks to the extensive experience of our in-house R&D centre, we have established reliable and lasting partnerships with top-tier producers—both in Ukraine and across the EU—recognised as industry leaders.

Direct sourcing from raw material manufacturers ensures the consistent quality of MTC Concrete products, while long-term collaboration allows us to confidently refer to these companies not merely as suppliers, but as true Partners.

Where can I see customer reviews about this product?

In the B2B and B2G market segments, customer reviews are rarely published, as the dissemination of information about the approaches and results of using specific admixtures often constitutes a commercial secret.

We believe that the best testimonial for a product is a successfully implemented project where the product was used. Reports on such projects are published after completion, subject to agreement with our partners. You can find all available reports in the “Information” section, or directly under the product if there is already an applicable experience that can be shared.

Do you have any completed projects where N-3 Admixture was used?

Yes, you can explore real-life experience with our products through completed projects in the "Information" section.

As for the practical application of this specific additive, you can find more details in the article: 

"Hydrophobic concrete additive N-3 from MTC Concrete - experience of use in the construction of a retaining wall".

"High-Quality Admixtures: A Solid Foundation for a Powerful Grain Storage Facility — A Solution for Oliyar".

Does this product have all the necessary certificates?

In accordance with the Law of Ukraine "On the Provision of Construction Products on the Market" (effective from 1 January 2023) and Order No. 594 of the Ministry of Regional Development, dated 27 March 2025, which approves the current List of National Standards including DSTU EN 934-2:2019, a certificate of conformity is no longer a mandatory document for concrete admixtures.

Instead, manufacturers are required to provide a Declaration of Performance (DoP) and apply CE marking (Conformité Européenne). The CE mark confirms that the product complies with European standards for safety and quality.

Consequently, to place concrete admixtures on the Ukrainian market, adherence to European norms and standards is necessary, rather than the previous mandatory certification requirements.

The manufacturing plant where this product is manufactured meets the requirements of the international standard ISO 9OO1:2O15 "Quality management systems. Requirements" (DSTU ISO 9001:2015 "Quality management systems. Requirements", IDT).

Is it possible to get a free consultation on this product?

Of course, you can get a free preliminary consultation either at the office of the "Koalida" company or fill out a request via the form on the Contacts page. You can also get advice from a technical specialist by calling the phone number: 077-500-11-00.

In our product range you will find solutions for almost any type of concrete mixtures and mortars that meet all quality and reliability requirements.
