Drainage renovation in just one week from the forerunner in the field
Drainage renovation is one of the most important but also the most demanding renovations of the property. The drainage unit at Vesivek has decades of experience in how to handle this. There are three factors at the heart of quality: Own installers and equipment, carefully considered installation concept and comprehensive contracts and documentation. That’s why Vesivek drainage renovation is a safe choice for you and your home. Order a free plinth condition inspection here.
Own installers and equipment
We want to promise our customers premium installation quality, and we know we only get it from our own installers. We don’t use subcontractors at all, so you don’t pay for middlemen. Quality and schedules hold when the installation is done entirely with our own resources. We ensure the quality with the best guarantees on the market; the installation warranty is five years.
Carefully considered installation concept
Our underdrain units only do drainage, not earthworks. And that really matters! A drainage renovation is not just trenching; it involves many technically demanding work stages. Poorly done drainage can even be harmful to a home. Over the decades, the installation process has been honed to perfection — that’s why we are able to renovate a detached house in 3 to 5 days on average.
Clear contracts and comprehensive documentation
A Vesivek contract includes everything, only rock work or other unpredictable stages will be invoiced as additional work. Prior to the renovation, the customer receives a written report on the condition of the drainage, so decision-making does not have to be based on a gut feeling. Likewise, all renovation work stages are described and reported to the customer. Thus, the property owner has the drainage system documented in black and white, to be used, for instance, when selling the property.
Symptoms of a defective drainage system

Plinth condition inspection™
Taking on a drainage renovation is a big decision, which is much easier to make, when you have up-to-date information about the current condition of the property. During the condition inspection of the plinth, our experts thoroughly review the condition of the drains and foundations, and if desired, the customer will receive a written and illustrated report on the inspection. The inspection and report are always free of charge for the customer. If moisture problems are not detected, the report provides peace of mind and serves as documentary evidence of a healthy home.Read more about the plinth condition inspection

Unbeatable price-performance ratio
There are many factors that contribute to the overall quality of a drainage renovation, such as developed installation concept, high-quality domestic products and skilled installers. When all these factors are in our own hands, we are able to serve our customers at a cost-effective price.
Renovation made easy
You will have one contact person to turn to throughout the renovation. The entire contract from the condition assessment to the final inspection is reported in writing, and we actively inform about the progress of the renovation. Should any problems arise, remember that the responsibility is always carried by one, designated party.
Vesivek is a forerunner in occupational safety, so our construction sites are safe for both installers and residents.
We pay attention to the environment
Each home and yard is considered individually. The handling of plants, tiling, etc. in the yard is agreed with the customer in advance. Construction waste is removed from the site in an appropriate manner. Well-planned work and own equipment minimise the amount of logistics.
The most common causes of moisture and mould damage to foundation structures:
- Surface water runoff into the building
- Defective gutter and rainwater systems
- Infiltration of surface water into the crawl space and other structures
- Penetration of pressurised water into the crawl space and other structures
- Capillary rise of water from the subsoil to structures
Proper drainage is the single most important factor in preventing the damages listed above!

Stages of a Vesivek drainage renovation
1. The foundations are dug open below the footing, the plinth is brushed clean and rough parts are leveled.
2. A dam plate is installed against the plinth as a moisture barrier
3. A cellular plastic cover is installed against the dam plate
4. The dam plate protection strip is installed
5. The drainage and rainwater pipelines, inspection and gutter wells and the basic water well are installed.
6. The drain pipes are covered with gravel and the filter cloth is applied
7. Frost insulation is installed and the ground is shaped
8. A capillary gravel edging is made and wooden frames installed The yard is cleaned up and finished off.
The most common property drainage problems
- The grading of the ground is improper or graded in a way that encourages water to flow towards the home.
- The lawn, topsoil and dirt / fine sand are attached to the foundations.
- Frost insulation is waterlogged and made of too thin styrofoam.
- The underdrain pipe is single-layer and 70 mm in diameter. Drain pipes are often damaged and clogged.
- Rising damp penetrates the structures.
- In a house with a false (fake) plinth, the wall structures are below ground level, allowing moisture to be diverted to the structures (waterlogged wooden beams, joists and insulations).
- There is masonry mortar in the ventilation gap which increases the transfer of moisture to the wall structures.
- The floor structures absorb capillary rising moisture.
