- Summary
Poorly executed foundation waterproofing can lead to leaks and moisture problems on walls. Often, these issues only become apparent several years after construction has been completed, when it is typically too late for thorough repairs. Renovating foundations is both challenging and costly.
Foundations are a critical element of any building, not only for ensuring stability but also for protecting against moisture and water ingress. Water will exploit every gap in the protective layers and every mistake made during the design or construction of the foundations. Therefore, properly securing basements and foundations is fundamental.
What Causes Errors in Waterproofing?
Most execution issues stem from working too quickly or from insufficient training of contractors. Waterproofing and thermal insulation materials require precise application, particularly in the case of moisture-proof and waterproof insulation. Even the smallest gap can become a potential leakage point.
The most common errors occur during the following stages:
- Selecting appropriate waterproofing materials and technology.
- Applying the moisture-proof or waterproof membrane.
- Connecting vertical insulation to horizontal insulation, as well as connecting horizontal insulation to sub-floor insulation.
- Sealing expansion joints, pipe penetrations, and other critical areas.
Effects of Errors in Waterproofing – How to Recognize Poorly Executed Waterproofing?
A warning sign that there is an issue with the waterproofing of a building’s underground section is damp walls on the ground floor where they meet the foundation walls. Other indicators include wet stains on walls, peeling plaster, or mold growth. Fixing such defects can be troublesome and may require costly excavation of the foundations.
One of the primary mistakes is the lack of a geotechnical assessment. Starting construction without knowing the soil conditions can lead to incorrect waterproofing choices. Another significant error in waterproofing planning is excessive cost-cutting. Replacing specified materials with cheaper and lower-quality alternatives—or omitting some materials altogether—or applying a product in a layer that is too thin, defeats the purpose and ultimately increases the cost of future repairs. Not only do you initially pay for low-quality materials, but over time, you’ll also have to repair their effects or failures and install new waterproofing.
Common Stages Where Waterproofing Errors Occur
- Selecting materials and technology: Choosing unsuitable materials or techniques for waterproofing.
- Application of membranes: Poor execution of moisture-proof or waterproof coatings.
- Connecting different insulation layers: Failing to properly connect vertical insulation with horizontal layers or sub-floor insulation.
- Sealing critical areas: Inadequate sealing of expansion joints, pipe penetrations, and similar vulnerable points.
Consequences of Waterproofing Errors
Errors in waterproofing lead to varying degrees of dampness or leaks within a home, which can be expensive to repair and highly disruptive for residents. The primary goal in such situations is to identify the source of the dampness. Unfortunately, people often attempt to fix the symptoms rather than addressing the root cause, leading to recurring issues.
Although many waterproofing failures present similar symptoms, the methods to resolve them can differ. Identifying the cause of leaks or dampness requires the expertise of a specialist. Only after a proper diagnosis can suitable waterproofing materials be selected and a repair plan devised.
How to Fix Waterproofing Errors?
The process of repairing waterproofing errors depends on various factors, including the type of substrate, its condition, moisture level, and the type of waterproofing materials used. It is crucial not only to utilize high-quality materials but also to implement technically sound material and construction solutions.
This means using the right materials in the correct manner and in the appropriate location. Often, this requires consulting with an expert who can assist in selecting the appropriate products and technologies for the specific situation.
How to Avoid Errors in Waterproofing?
1. Selecting the Right Waterproofing Materials
After assessing the water and soil conditions, it is essential to choose materials that suit the foundation's construction while adhering to these conditions. Proper material selection ensures compatibility and long-term effectiveness.
2. Proper Application of the Coating
The process of sealing foundations requires precision. Materials should be applied or installed according to the manufacturer’s recommendations and in compliance with best construction practices. Attention to detail during application is crucial for successful waterproofing.
3. Correct Sealing of All Connections
Special care must be taken to properly secure horizontal and vertical layer connections, ensuring a seamless transition. Additionally, careful sealing of expansion joints and pipe penetrations is necessary to prevent leaks and maintain the integrity of the waterproofing system.

Summary
Foundation waterproofing is a critical component of any building, as it prevents water and moisture from penetrating the structure. Mistakes in waterproofing can lead to serious issues, such as the deterioration of building materials, mold growth, and even structural damage to the building. Repairing waterproofing is a complex and expensive process, often requiring excavation of the foundation, which adds to the costs and logistical challenges.
In some cases, foundation injections may also be necessary. This technique involves injecting specialized sealing substances into areas where problems occur. Foundation injection is typically employed when traditional waterproofing repair methods are insufficient or unfeasible. It is particularly useful in cases where access to the damaged area is limited or impossible.
Injections can also be used to strengthen the foundation structure, enhance its resistance to water and moisture, and repair cracks and gaps. However, it is essential to note that foundation injection is a complex procedure that should be performed by an experienced specialist. Always consult an expert before deciding to use this method.
Errors in waterproofing often stem from improper material selection, failure to follow manufacturer instructions, or a lack of technical expertise. For this reason, consulting with an expert who can recommend the right products and technologies is always a wise decision. The choice of materials should be based on their quality and properties, not solely on cost. Remember, initial savings may lead to significantly higher expenses in the future.
