Blitz cement or hydroseal for concrete GU 14

Choosing the correct materials is essential for waterproofing concrete structures in order to ensure their longevity and durability. For concrete GU 14, Blitz cement and Hydroseal are two well-liked choices in this regard. Each has special qualities and uses that make them appropriate for various projects and environmental circumstances.

Because of its high strength and quick setting time, blitz cement is well-suited for last-minute repairs and emergency scenarios. It is particularly helpful in environments like industrial settings or infrastructure projects where downtime must be kept to a minimum. It is also a preferred option for underwater applications where traditional concrete would struggle because of its quick setting time.

Conversely, Hydroseal for Concrete GU 14 is made expressly to offer a strong waterproof covering. It is a great option for foundations, basements, and other areas where water intrusion is a possibility because of its exceptional ability to create watertight seals. Because of its special formulation, Hydroseal is able to deeply penetrate concrete, creating a solid bond that prevents water from penetrating and increases the structure’s overall durability.

For your upcoming building or repair project, knowing the benefits and uses of Blitz cement and Hydroseal for concrete GU 14 will help you make an informed choice. We will go more into each product’s unique features, advantages, and best use cases in the sections that follow to assist you in choosing the one that best suits your requirements.

It’s critical to comprehend the differences between Blitz cement and Hydroseal when selecting either product for concrete GU 14. Because of its quick setting time and high early strength, blitz cement is well-suited for projects that need to be completed quickly and have early load-bearing capabilities. For structures exposed to water or high humidity, Hydroseal, on the other hand, excels in water resistance, offering superior durability and protection against moisture penetration. The particular requirements of your project will determine which option is best, weighing strength and speed against long-term durability and moisture resistance.

Features of the mixture

Cement, fillers like quartz sand, plasticizers, and hardeners (modifiers) based on polymers make up Composition GU 14. Water exposure causes the formation of a fast-setting solution with a high adhesive capacity.

Substances known as modifiers enable a rapid cement mixture hardening. Their manufacturing secret chemical makeup is not disclosed by the manufacturer on the packaging.

The Gidroblok plant produces Hydroplomba GU 14. The business is based in Moscow. producing dry concrete mixtures as a profession. Founded by Vadim Alekseevich Bulanov in 2015.

Recognized works by OOO Gidroblok:

1. MK 1.5 waterproof tile adhesive;
2. cement joint waterproofing GZ 10;
3. vapor barrier mixture GO 16;
4. hydro concrete for use at low temperatures and much more.

Application goals

What the GU hydro seal is used for:

• Elimination of leaks in concrete wells, their waterproofing.
• Elimination of cracks and defects in the ceilings of reinforced concrete structures.
• Repair of pool walls, hydraulic structures.
• Waterproofing of cellar walls, vegetable bases.
• Stopping local leaks in the main heating system, sewerage.
• Elimination of cracks in underground metro structures and passages.

The GU 14 hydraulic seal is very popular due to its wide range of applications. It is made in containers weighing 10 kg. Packed in big buckets because concrete well rings are waterproofed by sealing big holes and cracks.

Technical characteristics

Hydroplomba is produced in accordance with the manufacturer’s TU, TU number 5745 – 001 – 27705993 – 2015, rather than the GOST standard.

GU 14 is composed of a blend of cements and activators as additives. As a result, possesses the following traits:

• The viability of the composition varies from 15 sec (beginning) to 2 minutes (end).
• Minimum surface and ambient temperature during application is 5 °C, maximum is 35 °C.
• Water resistance level – W14.
• Frost resistance – at least 100 cycles of freezing and defrosting.
• Compressive strength from 7 to 40 MPa after 1 hour and 28 days, respectively. The parameter is given when curing in water.
• The adhesion index for 1 hour and 28 days is 0.5 MPa and 1.5 MPa, respectively.

The composition can be used to repair heating and plumbing systems because it can tolerate temperatures up to 120 degrees when exposed continuously.

One clear benefit of the GU 14 mixture over other hydroseals is its environmental friendliness. The drinking water quality remains unaffected by a filling composed of this material.

The mixture can be applied in alkaline environments that range in pH from 5 to 14, which are fairly aggressive.

The maximum size of the dry matter fraction is 2.5 mm.

How to calculate consumption?

The size of the crack in the concrete base is taken into account when calculating the quantity. You will require a maximum of 2 kg of material for a hole that is 10 cubic meters in diameter. The amount consumed is determined by the size of the cavity created when the composition of the concrete was destroyed.

The typical crack size is between 5 and 10 cm in height, width, and length. As a result, one to two kilograms of the GU 14 mixture may be consumed.

Safety precautions

There are safety precautions you must take when handling a hydraulic seal. When the mixture hardens with water, it becomes an alkali, which is harmful to the skin, eyes, and respiratory system.

List of tools

The list of supplies and equipment varies based on the location of the work. Thus, the following tools are needed to seal a leak in a concrete slab:

• A hair dryer. Used to heat the surface at a temperature of 5 degrees. Accelerates the setting of the mixture.
• A spatula or other construction tool (perforator) to widen the gap and remove debris and cement chips.
• A drill with an attachment. Needed for mixing the cement mixture with water.

If the goal is to remove small cracks, the latter tool might not be required.

To prepare for GU 14, follow these easy guidelines. Mix a small amount of water with the blitz cement. It should have a consistency like soaked, moist soil.

This can be applied straight onto a plastic bucket lid from GU 14. Using a spatula, it is simple to clean after it has hardened.

Method of application

Used exclusively in damp conditions.

Application guidelines:

• Clean the leak site with a tool, for example, a spatula from loose concrete.
• Clean the crack from cement milk, dust and dirt.
• Expand the crack in the form of a small pyramid, very similar to a dovetail. The depth of the hole should be more than 5 cm.
• The finished mixture is formed in the form of a cone and pressed into the hole, trying to maintain pressure for up to 3 minutes.

Once the water has stopped flowing from the mixture’s placement, a seam hydraulic block, such as GZ 10-m, is used to further seal the GU 14 crack.

A lot of artisans suggest the following. Installing a hose to drain the liquid and cement it in the hole is advised if the hole’s diameter is greater than 10 cm. Next, seal the opening. In this instance, though, the leak won’t be stopped because water will still run down the hose.

A work scheme from the manufacturer, GU 14, can be studied to obtain a visual representation of the necessary work. The figure illustrates how simple it is to stop leaks originating from the corner of a basement or living area by using a plug shaped like a truncated cone. The plug is installed expanded to act as a buffer between the liquid and the wall, even though the hole’s diameter may be small.

Gidroblok uses another line of products as additional materials to remove defects. This is penetrating insulation and joint waterproofing GZ 10, which raise the grade of concrete and strengthen the concrete base. We refer to it as the gidroblok GP 4.

Because of its unique properties, water seal GU 14 cannot repair flaws in a wall or other reinforced concrete structure when the outside temperature is below fifteen degrees. You need precisely this indicator in order to dry the composition.

For this reason, traditional heating is employed in addition to the material. The mixture will set and stop leaks more quickly if you use a hair dryer with a hot air stream.

Storage and terms

The composition can be stored at any sub-zero temperature, according to the manufacturer. All you have to do is shield the material from moisture and dampness. Shelf life: within eighteen months of the manufacturing date.

All that’s needed for the bucket stand are wooden pallets. This is necessary to make sure that the containers are kept out of a damp, cold environment.

Advantages and disadvantages

A hydroseal’s ability to harden quickly after mixing—even under water pressure—is its greatest benefit.

• Environmental friendliness of the composition. It can be used in water supply system.
• Great compressive and tensile strength that increases over time.
• Quick adhesion to any concrete surfaces.

Apart from its benefits, the hydraulic seal has drawbacks as well. The primary one is that applying and mixing the composition requires efficiency. It hardens very quickly, so you might not be able to bridge the gap in time.

Subzero temperatures make it impossible to fix cracks and holes, which can be problematic during the winter.

When it comes to fixing small leaks, like basement cracks or swimming pool waterproofing, Hydroplomba GU 14 performs admirably.

The GU 14 hydroseal is used to seal the seams of concrete rings, according to customer reviews. Hardens in 15 seconds, instantly. No drawbacks.

Cracks are treated with a cement, GU 14, and fireclay mixture. Compared to using a pure mixture for the seal, this composition is more cost-effective.

Average prices

In the Russian Federation, a 10 kg bucket of GU 14 typically costs between 1200 and 1300 rubles. In contrast, a two-liter can of Ceresit CX 1 will set you back 600 rubles. Despite being produced domestically, this material has qualities that are comparable to those of European brands.

The particular requirements of your project will ultimately determine whether to use Hydroseal or Blitz cement for concrete GU 14. Each material has special advantages that can improve the performance and longevity of your concrete constructions. Making an informed choice can be aided by your understanding of these advantages.

Because of its quick setting time, blitz cement is a great choice for projects that need to be completed quickly. Structural stability depends on the concrete’s ability to sustain large loads and stresses, which is made possible by its exceptional strength and durability. Blitz cement is also adaptable and appropriate for a variety of uses.

Conversely, Hydroseal is made expressly to increase concrete’s water resistance. This makes it a great option for projects that will be exposed to moisture, like water tanks, swimming pools, and basements. By lowering the chance of damage over time and preventing water penetration, hydroseal helps to prolong the life of the structure.

The choice you make will rely on the project’s priorities. Both materials have advantages. For those who prioritize strength and speed, Blitz cement is the best option. When it comes to water resistance, Hydroseal will offer the necessary protection. You can choose the material that best suits your needs by taking into account the particular requirements of your concrete project.
