Trenchless basement waterproofing from the inside

Why does moisture penetration of the basement wall occur? In most cases, the actual problem is not moisture or leaky walls, but certain properties of the building substance that cause the wall to absorb moisture via the capillary effect, similar to a sponge. This capillary effect occurs more strongly the more the building substance of the basement wall is negatively charged electrically.

With the DRYMAT® system, we induce a positive electrical potential in the basement wall. This eliminates the capillary effect. This effectively protects the wall from moisture. Incidentally, the same principle is also used for sportswear, where the electrical potential of a small button battery is used to actively conduct moisture out of the clothing.

During electrophysical basement dehumidification, only a positive electrical potential is induced in the wall. This means that hardly any current flows and there is no exposure to electrosmog in the house. DRYMAT® basement waterproofing is minimally invasive and does not require solvents or injections.

What is the cost of basement waterproofing?

An electrophysical basement waterproofing from the inside with the DRYMAT® system costs CHF 15'000 CHF to 20'000. This estimate refers to a house with a floor area of 60 m². The exact price depends on the following factors: Travel distance, length and accessibility of the wall, building material, and aesthetic requirements. In comparison, manual basement waterproofing from the outside quickly exceeds these costs by a factor of three, partly because of the extensive earthworks involved.

What consequential damage can occur with damp masonry?

Moisture leads to higher heating costs, causes damage to the building fabric and thus continuously reduces the value of the property. If mold develops, it also creates an unhealthy climate in the affected rooms. This can lead to headaches and respiratory diseases. Further Information on moisture problems and mold is provided by the Federal Office of Public Health (FOPH).

How does electrophysical basement waterproofing work?

An electrical potential is generated with the DRYMAT® control unit and electrodes installed in the basement wall. This counteracts the suction voltage in the wall. In this way, moisture can no longer be transported into the wall and rise upwards. The residual moisture in the wall evaporates over time. In this way, the wall is permanently protected from water penetration, with the basement wall drying completely within 0.5 to 3 years.

Why basement waterproofing from Haustrocknung.ch?

We are the exclusive representative of DRYMAT® in Switzerland and have been using the process successfully for over 10 years. Compared to conventional methods, electroosmotic basement waterproofing with DRYMAT® is safer, cheaper, more ecological and also ÖNORM-certified. While DRYMAT® can be installed in the cellar wall in a minimally invasive manner, conventional methods usually involve extensive intervention in the building structure.

What does basement waterproofing cost in Switzerland?

Electrophysical basement waterproofing with DRYMAT® costs approximately CHF 15,000 to 20,000 for a single-family house with a floor area of 60 m². This includes the entire order processing - from the careful analysis of the cause of the moisture to the installation of the DRYMAT® system and the follow-up measurement. Request a quote now

On what factors does the price of basement waterproofing with DRYMAT® depend?

The price depends on the following factors: length and accessibility of the walls, building material, the demands on aesthetics as well as the duration of the journey. In addition to the installation of the DRYMAT® system, a careful analysis of the cause of the dampness is an expense. We do this in order to be able to guarantee the results.

What are the annual electricity costs?

The DRYMAT® system generates electricity costs of about CHF 50 per year. This consumption is primarily due to the control unit.

Does DRYMAT® incur maintenance costs?

No, the DRYMAT® system does not incur any maintenance costs. We make the whole installation from titanium. We give you a 10-year warranty on the control unit. In addition, you will receive another 10 years manufacturer's warranty. On the installation in the masonry you get 2 years warranty according to SIA.

How does electrophysical basement waterproofing work?

Moisture can only rise in the wall if the building substance has a negative electrical charge. With the DRYMAT® system, we ensure that the basement wall is positively charged in relation to the ground. This prevents new water from penetrating the building substance on the one hand, while on the other hand the excess moisture evaporates within 0.5 and 3 years. This process can be avoided with an intelligent Basement ventilation be accelerated.

What are the advantages of basement waterproofing with DRYMAT®?

Both the DRYMAT® system and our application procedure are scientifically recognized and ÖNORM-tested. While conventional waterproofing methods using construction chemicals or resins are environmentally harmful and require extensive intervention in the building fabric, the DRYMAT® system is ecologically harmless, can be installed with minimal invasiveness and also actively combats moisture.

How reliably does basement waterproofing with DRYMAT® work?

In case of non-pressing moisture sources, such as seepage water or soil moisture, we give a guarantee for the measurable results by the DRYMAT® system. In case of periodically pressing slope water or an adjacent water vein, the electrical potential will at least cause a faster drying of the masonry. In any case, we make a thorough analysis of the cause of moisture.

What to consider in terms of basement waterproofing?

Hermetically sealing the building fabric inevitably increases the risk of consequential damage such as mold. Basement waterproofing should therefore, if possible, not hermetically seal off the building fabric, but ensure that the wall can continue to «breathe». More on this in guide «Waterproofing the basement»

Why do basement walls become damp?

In most cases, it is not the leak in the wall or the source of moisture that is the real problem, but the nature of the building fabric: this causes the moisture to be absorbed by the cellar wall via the capillary effect, similar to a sponge. However, this capillary effect only occurs if the building substance has a negative electrical charge. More on this in the «Damp walls» guide

How does DRYMAT® seal damp basement walls?

By inducing a positive electrical potential in the wall, the capillary effect is eliminated (so-called electroosmosis). While the capillary effect was previously responsible for the "rising" of moisture, it can now no longer transport moisture in the building fabric. Incidentally, the same principle is also used in state-of-the-art sportswear to transport moisture out of the clothing.

In what cases can electrophysical basement waterproofing be used?

The DRYMAT® system is effective for non-pressing moisture sources. In the case of pressing slope water or an adjacent water vein, the electrical potential of DRYMAT® is strong enough to dehumidify the building structure. In any case, we conduct a thorough analysis of the source of moisture beforehand.

When is electroosmotic basement waterproofing not effective?

An oppressive source of moisture makes it difficult for the electrical potential of the DRYMAT® installation to effectively dry the building structure. However, dehumidification of the building structure is safely achieved. Pressing moisture sources include adjacent water veins or pressing slope water. In any case, we make a thorough analysis of the source of moisture at the beginning, because this way we can guarantee the results.

What is the procedure of electrophysical basement waterproofing?

After the free initial telephone consultation, we will prepare an offer for you. If you accept the offer, we first make a detailed analysis of the cause of moisture at your site, where we perform various measurements. If there are no conditions that exclude the use of electrophysical basement waterproofing, we install the DRYMAT® system. 18 months later, we perform a moisture measurement to verify the drying effect.

How long does basement waterproofing with DRYMAT® take?

The installation of the DRYMAT® system takes about 3 - 5 days for a single-family house. Afterwards, the building fabric is effectively protected against moisture penetration. It can take 0.5 to 3 years for the excess moisture in the building fabric to dry out. Drying can be achieved with an intelligent Basement ventilation be accelerated.

Does the installation of DRYMAT® create noise or dirt in the house?

When we mill the slots for the wiring in the wall, noise is generated in the rooms concerned. Dust, on the other hand, is generated very little because we mill with an exhaust hood and connected industrial vacuum cleaner.

How is the effectiveness of DRYMAT® monitored?

We monitor the effectiveness of the DRYMAT® system with a moisture measurement 18 months after installation of the system. This should show a significant decrease in residual moisture in the building fabric.

C. T. from Zurich says:

«The installed DRYMAT® system copes with the difficult task. In previous years, I had real water ingress through the stamped concrete in the basement. But that has failed to happen with the intense rains of the last few days! The electrophysical DRYMAT® system really seems to be ideal.» ➝ other references

Cost of basement waterproofing

The DRYMAT® system costs between CHF 15,000 - 20,000 for a house with a floor area of 60 square meters. This includes a thorough analysis of the moisture problem by a building expert, the installation of the system and the follow-up measurement. Added to this are the operating costs of approx. CHF 50 per year.

The exact price is influenced by the following four factors:

Duration of the journey: How far away is the property?
Accessibility of the affected walls: Do fixtures make installation work difficult?
Construction material of the walls: How complex is the installation in the affected building material?
Aesthetics: Do requirements for aesthetics complicate installation work?

Methods of basement waterproofing at a glance

Electrophysical basement waterproofing is able to dry out the building structure down to the bottom of the foundation. In contrast to the vertical and horizontal waterproofing methods, basement waterproofing with the DRYMAT® system requires neither structurally delicate interventions nor the use of delicate chemicals.

Order processing

After contacting us, e.g. via the contact form, our building experts will call you for an initial consultation. Together, we will specify the moisture problem and show you potential countermeasures.
If you are interested, the second step is for us to come to the affected property to take a closer look at the moisture problem on site. For this purpose, we carry out various measurements on the building fabric.
Thirdly, we will prepare either an offer or a building survey for you. You then decide whether you want to accept the offer.
If yes, in the fourth step we start the installation of the DRYMAT® system. This takes about 3 - 5 working days for an average single-family house with a floor area of 60 sqm.

Installation procedure: We drill electrodes into the damp masonry as well as into the floor and mill narrow slots. Then we lay the cabling, mount the control unit and test the system. The milling work causes noise in the basement. There is little dust because we drill and mill with an industrial vacuum cleaner connected.
After successful testing, in the last step we plaster the slots and put the plant into operation. If you wish, we will perform one or more periodic re-measurements.
