Basements built since 1980


Standards and Regulations for Basement Waterproofing: 3 Things you Need to Know

Basements have particular waterproofing requirements. Whether you need to prevent pressing groundwater, accumulating seepage water, or live in a flood-prone area, it's essential to consider your regional conditions and take effective measures to waterproof your basement.

We’d suggest you have a full ground survey on the plot of land you're building on, which will provide you with all the information you need on the subsoil conditions on site, as well as offering suitable recommendations for waterproofing and creating the foundation of your basement. The aim is to keep every single part of your basement dry, all year round.

To achieve this, however, and to avoid leaving waterproofing measures to the discretion of the contracting construction company, there are specific, clear standards and regulations in place. It goes without saying that these provisions must be adhered to and communicated to the construction company.

Thorough waterproofing of your basement is indispensable

Imagine the following situation: you've decided to build a prefabricated basement and handed the project over to a company who are supposedly experts in the field. Once the construction process is finished and you've been living in the space for a couple of months, you suddenly notice that the walls are damp or even detect the first signs of mould. And just like that, your dream home is transformed into a nightmare.

These issues are often a result of insufficient waterproofing measures. The bottom line is that only a basement built according to all the relevant specifications and regulations will live up to your expectations. Standards and regulations for basement waterproofing serve to protect the building structure, as well as your health and your bank account. Don't settle for anything less than a waterproof basement and don't make any compromises.

Having been in this business for 37 years, we know a thing or two about basement construction. Customer satisfaction and good value for money have always been at the heart of our work, and our experts know exactly which standards and regulations apply when waterproofing basements, as well as which procedures achieve the optimal results in each case.

The regulations are vital

We don't do things by halves. We know that only prefabricated basements built strictly following regulations and the applicable specifications provide customers lasting satisfaction. Exterior waterproofing is one of the most important basement components, as every basement must be waterproofed against groundwater from the outside.

The DIN 18195 standard on waterproofing of buildings [6] makes the distinction between the following types of waterproofing (loading conditions);

→ 1) Waterproofing against soil moisture (capillary moisture, retained water) and non-accumulating seepage water
→ 2) Waterproofing against outside pressing water.

Your ground surveyor can tell you the applicable load conditions.  

In principle, the manufacturing process for different waterproofing elements can vary depending on each individual case. There are several suitable structural designs and a wide range of products available in the industry, which have proven to be effective and are well established in the market.

The "WU" guidelines (German guidelines for watertight structures) are also particularly important. The provisions issued by the DAfStb (German Committee for Reinforced Concrete) contain detailed requirements for proper planning and execution of concrete builds. This guarantees all aspects of the production process are safe and comply with all applicable regulations and ensures the final product is of the highest possible quality


And finally…

Standards, regulations, guidelines... When it comes to building a new basement, you shouldn't have to make any compromises. Insist on having an experienced, established and highly competent company right from the beginning who follow all of the regulations, to ensure excellent quality and a product that lasts a lifetime – and beyond!
