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.
Why do most customers choose a Vesivek renovation?

Water away from the plinth within a week!
The highly developed operating model as well as Vesivek’s own equipment and installers ensure a smooth contract. Each renovation site is thoroughly inspected and the implementation is carefully planned in advance. This enables us to complete the renovation of a detached house in an average of 3 to 5 days.
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.
Vesivahti Online™
Vesivahti Online™ is Vesivek’s service, where a device installed in the drainage system reacts to a rise in the water level and sends an automatic alarm. In this way, you have time to react to the problem before the flooding water does any damage.
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.
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.

Why is timely renovation of the drainage system so important?
Drainage renovation is a big investment and therefore it is easily postponed. Furthermore, the drains are not visible, so their maintenance and inspection procedures are easily forgotten. That constitutes a risk of dysfunctional drains causing damage to the home’s subfloor structures for a long time before any signs of problems become apparent. At that point, other structures on the property may already have suffered damages, and the price of renovation may rise significantly.

- If moisture has damaged the subfloor structures, in addition to drainage repairs, other repair measures will have to be taken.
- At worst, mould and other microbial growth caused by moisture migrate into the indoor air and can cause serious health problems.
- In principle, an insurance does not cover any damage caused by defective drainage. Renovations of subfloor structures are usually large-scale contracts and the property owner has to pay for it all.
Stages of a Vesivek drainage renovation
The foundations are dug open below the footing, the plinth is brushed clean and rough parts are leveled. A dam plate is installed against the plinth as a moisture barrier.
A cellular plastic cover is installed against the dam plate. The dam plate protection strip is installed
The drainage and rainwater pipelines, inspection and gutter wells and the basic water well are installed.
The drain pipes are covered with gravel and the filter cloth is applied.
Frost insulation is installed and the ground is shaped.
A capillary gravel edging is made and wooden frames installed The yard is cleaned up and finished off.
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!
