Basement waterproofing is essential protection against damp and groundwater. The protection of the basement is crucial already during the construction phase of the house, as later improvements can be costly and difficult to carry out. Good preparation and selection of the right materials and application techniques are the basis for effective basement protection.
Inappropriate basement waterproofing can lead to a number of problems, such as mould, mildew and structural damage to the building. It is therefore important to thoroughly understand waterproofing methods and know, how to make waterproofing the right way. In this guide, we will take you step by step through the process of water and damp proofing your basement.
Preparation for basement waterproofing
The first step in the process basement waterproofing are soil and water tests. These detailed analyses make it possible to determine the exact groundwater levelwhich is key to choosing the right insulation method.
Depending on the outcome of the tests, the appropriate thickness of insulation and the materials that will work best should be selected. It is important to prepare the basement surface for waterproofing work by:
- Removal of irregularities
- Ensuring correct connection of horizontal and vertical insulation
Only properly conducted soil and water tests and properly selected groundwater level ensure effective insulation of basement walls. Remember that these steps are essential to ensure the durability and effectiveness of the insulation work carried out.
Horizontal and vertical insulation of the basement
Insulating the basement is crucial to maintaining the right conditions inside the building. In this context, vertical insulation on external walls and horizontal insulation on the footings and under the floor play a fundamental role. Thorough application of waterproofing materials, such as bitumen membranes or waterproofing membranesis necessary to ensure effective protection.
When insulating a basement, there are several key aspects to consider:
- Vertical insulation walls should be made of durable and moisture-resistant materials.
- The horizontal insulation of the footings must be carefully combined with the insulation under the floor.
- It is recommended that vertical insulation protrude a minimum of 30 cm above the ground surface to protect the walls from ground water.
- Securing corners and joints requires special attention to avoid leaks.
Best practice involves attention to detail during each stage of insulation. Done correctly, this will minimise the risk of damp problems and provide long-lasting protection for the building. When choosing bitumen membranes i waterproofing membranes, it is advisable to look for products from proven manufacturers, which guarantees quality and durability.

Best materials for waterproofing a basement
Selection of suitable waterproofing materials is crucial to the effectiveness and durability of basement waterproofing. There are several important types of materials to consider to provide water and moisture protection.
Bitumen sheeting, particularly on a polyester matrix, is a proven choice for its durability and weather resistance. It is often used as the primary material in waterproofing systems.
Another option is two-component insulations. They are characterised by high elasticity and excellent insulation properties, making them ideal for protection against ground water and dampness.
It is also worth noting sealing compoundswhich are an important complementary element in waterproofing. They can be used to precisely protect difficult-to-reach areas and material joints.
Use of appropriate waterproofing materials in accordance with the technical specifications is crucial to the long-term effect and effectiveness of the basement water protection.
Proper waterproofing of the basement
Well executed basement waterproofing ensures effective moisture protection for many years to come. Every step of the process, from ground preparation and investigation, to the selection of appropriate horizontal and vertical insulation techniques, to the careful selection of materials, plays a key role in achieving lasting results.
Proper insulation A basement is an investment in the health and safety of the occupants, minimising the risk of moisture-related problems such as mould and fungus. In addition, correctly executed waterproofing affects the longevity of the entire building structure, protecting its foundations from degradation and ensuring stability.
By following the steps described and choosing high-quality materials and proven methods, you can achieve effective basement waterproofing that will last for many years. Remember that any negligence in the waterproofing process can lead to serious structural problems, so it is worth approaching the task with full commitment and professionalism.
