Waterproof concrete and load classes

Find out here which class of waterproof concrete  is suitable for which application. The main difference lies in the intensity and duration of exposure to water.

Load class 1

In this class, waterproof concrete protects structures with a low to moderate water load. This means that the concrete is mixed and processed in such a way that it can withstand normal to slightly increased moisture levels. This usually refers to buildings that could come into contact with water but are not exposed to constant or intensive loads.

Load class 2

For structures with a significantly higher water load, watertight concrete of load class 2 is used. Increased water load means: structures that are exposed to permanent water contact or increased moisture, for example swimming pools, drinking water tanks or construction projects in water-rich environments. Here, watertight concrete must be particularly resistant in order to prevent the penetration of water over long periods of time.

 

DIN standards

DIN standards are important in order to be prepared for certain effects or conditions on construction sites. For example, a soil survey may specify that construction should be carried out in accordance with DIN 18533. Or: The building has rooms in the basement areas that are particularly worthy of protection, such as archives, server rooms, etc. Here too, waterproofing in accordance with DIN 18533 is mandatory.

DIN 18533

DIN 18533 is a standard that specifies requirements for the waterproofing of components in contact with the ground, such as basement walls, foundations and penetrations in buildings. It defines the various water exposure classes and specifies the necessary protective measures to prevent the ingress of water. As a protective measure, liquid or sheet waterproofing materials are also applied to the exterior walls. This may be important for you as a building owner, builder or contractor for the following reasons:


Product specifications

The standard specifies the requirements for the water impermeability of building components in contact with the ground. Cable and house penetrations fall into this category and must meet the relevant requirements to prevent water ingress and protect the integrity of the building structure.

Quality assurance

The standard also serves as a quality standard for the waterproofing of buildings. As a manufacturer, we produce in accordance with this standard and thus ensure that our products meet the requirements for water impermeability.


Reliability

If you as a building owner really want to reliably and effectively prevent water from entering your building, we recommend our products - i.e. from a manufacturer that complies with the legal standard.


Legal requirements

Many countries and regions require building owners by law to comply with building standards such as DIN 18533. Use products that comply with the relevant standards, avoid legal problems and ensure that you can complete your project on schedule.

As professionals in the construction industry, it is essential to always be up to date with the relevant standards. One of these is DIN 18533, which deals with the waterproofing of building components in contact with the ground. DIN 18533 specifies detailed requirements and recommendations for the planning, execution and quality assurance of waterproofing measures. This applies to various areas such as basement walls, foundations and floor slabs. By complying with this standard, we not only ensure the longevity of structures, but also effective protection against ground moisture and backwater. This is crucial for the quality of construction and the satisfaction of our customers. As experts, we set the standards high and always strive to implement best practice in construction. Knowledge and application of DIN 18533 is an integral part of our commitment to quality and professionalism.

DIN18533-1 describes the requirements, planning and implementation principles for the waterproofing of components in contact with the ground. For the planning phase, this means that all relevant criteria must be taken into account. Criteria are for example
- Water exposure classes
- Crack classes
- Room utilization classes etc.
DIN18533-1 describes that these must be determined and weighed up in advance! Only then are the product requirements in DIN18533-2 and 3 applied.

In short, the DIN 18533-2 standard defines the requirements for products that are to be used for waterproofing with sheet materials. We offer suitable product series for this DIN, such as the FU/F+L/W1 for non-pressing water and the FU/F+L/W2 for pressing water. These casing pipes with a fixed/loose flange design have been specially developed to seal your construction site 100% in the event of pressing or non-pressing water. We also offer them in multiple versions. DIN 18533-2 provides us with precise guidelines on HOW these products should be manufactured. Essentially, these are specifications that we must observe during production. For our product range for pressurized water, for example, this means that the fixed flange must be at least 10 mm thick and have a circumference of 160 mm. The loose flange must also be at least 10 mm thick and have a circumference of 150 mm. M20 bolts are provided to ensure optimum and robust compression of the web-shaped seal between the fixed and loose flange. If these criteria are met in our sealing product, sealing can be carried out in accordance with the DIN standard!

Similar to DIN 18533-2, DIN 18533-3 also specifies certain requirements for the product, but specifically for sealing with materials to be applied in liquid form. This is our FU-KF, the lining pipe with adhesive / filler flange. This product requires a 120 mm circumferential adhesive / filler flange. This enables perfect application of the liquid sealing material. If these requirements are met, DIN-compliant sealing is possible!

 

Water exposure classes

This overview will help you to better understand the protective effect of our products against different water-related situations.

W2.2-E: pressing water

Stagnant water of more than 3 m (pressing water): Even if the water rises higher due to damming or other reasons, our products provide the necessary protection.

W1-E: non-pressing water

For highly permeable soils and materials: Areas in which there is no permanent accumulation of water. Drainage systems are in place here to regulate the flow of water.

W2.1-E: moderately pressing water

Backwater up to 3 m (moderately pressing water): If water presses against the building component, for example in areas with less water-permeable subsoil, our products offer reliable protection. Groundwater up to 3 m (moderately pressing water): Our products also protect against rising groundwater.

Elastomers

On construction sites, choosing the right materials is crucial to the success of a project. At UGA, we understand the requirements and challenges that our customers face on construction sites, which is why we offer awide range of elastomers inconjunction with our products. On construction sites, choosing the right materials is crucial to the success of a project.At UGA, we understand the requirements and challenges that our customers face on construction sites, which is why we offer a wide range of elastomers. We now explain which elastomers we offer in conjunction with our products and where the individual strengths lie!

Elastomere-en

Elastomers are polymeric materials that can deform under the influence of external forces, but return to their original shape once the forces have been relieved. These elastomers are known for their elasticity and flexibility, making them ideal for use in our products. In our cases, we use a wide variety of elastomers in our products such as rubber press seals (GPD), ring-space seals (RRD) or system inserts, depending on the customer's wishes and requirements. For example, these elastomers, also known colloquially as rubbers, are pressed between the metal plates in our rubber press seals so that core drill holes or similar can be optimally sealed gas- and watertight.

 

What does 2.5 bar water pressure mean?

How often do we hear the sentence: "I'd better play it safe and take the 5 bar version!" This belief that more is better and safer often leads to customers buying the more expensive versions that they don't actually need.

To better understand the topic, let's first take a look at the basics. Bar is a unit of measurement for pressure. One bar is roughly equivalent to the pressure generated by a 10 meter high column of water. This means that when we talk about 5 bar water pressure, imagine that the water forms a column 50 meters high. That's a considerable amount of pressure, far in excess of what is actually needed in most applications. See for yourself.

Stainless steel

What is the difference between V2A and V4A? We often encounter this question when it comes to choosing between V2A and V4A stainless steel. We bring light into the darkness! The difference lies in the composition: V2A consists of chrome, nickel and steel and offers outstanding corrosion resistance, especially against moisture, which ensures a long service life. V4A, on the other hand, contains molybdenum in addition to the main components. This additional material gives the stainless steel enhanced protection against even more aggressive environments such as salt water, chlorine and chemicals. No matter which variant you choose, we can provide you with high-quality stainless steel that meets your requirements.
