Damp, inhospitable churches: it’s a problem that has bedeviled congregants and church leaders for centuries. Here’s a space age solution to the problem that has proven surprisingly effective in churches and historical buildings in 22 countries. Many churches suffer from rising moisture, having been built at a time when the sources of the problem were poorly understood. That’s no longer the case.

Aquapol is a company with a 30 year track record in drying out more than 50,000 buildings using a revolutionary technology.

The solution involves the installation of a device no bigger than a cake tin, with no batteries, electrical connections or moving parts. As far as green solutions go, you can tick that box. Another factor to bear in mind: a dry building is cheaper to heat. Plus there is the fact that Aquapol creates a negative ion-rich environment which is beneficial for human wellbeing, similar to that experienced when visiting the beach or a waterfall.

Conversely, the presence of mold and damp air resulting from wet masonry creates an uncomfortable atmosphere for church goers.

Aquapol has had astonishing success in drying out churches and historical buildings in 22 countries for three decades. The system works by utilizing natural energy forces to reverse the electrical polarity of water molecules in the walls, driving them back into the ground. The name is derived from “aqua” – Latin for water – and “pol” – an abbreviation for polarity.

The inventor, Willie Mohorn of Austria, received the Viktor-Kaplan medal for his outstanding contribution to the advance of technology and science. He was also an honorary prize by the Austrian Ministry of Science, while Aquapol received the coveted Gold Medal at the Novelties Fair in Nuremberg, Germany.
St MarienAustrian TV science journalist Dr Hans Kronberger investigated the Aquapol technology and included in his research the 900-year-old church of St Marein (pictured left) in Austria. He wanted to see if the drying out claims made by Aquapol were valid or not. The church had been “renovated” with a new plaster a few years earlier, but the problem of rising water refused to go away. The sandstone walls had been literally sponging up the water for years. It became so wet that mold was developing on the walls and churchgoers were suffering from the excessive humidity.

After Aquapol tackled the problem, the humidity was demonstrably reduced by at least a third within just a few months. Today all of the walls are dry and the musty smell has disappeared. The impressive sandstone building is shining in new brilliance. The smell of frankincense after festival services is the only odor the churchgoer takes home.

St Marien priest, Father Othmar Stary, does not believe in black magic. He believes that the phenomena which allows Aquapol to work so effectively have not been sufficiently explored by physics. And he adds: “I am convinced that nobody has a monopoly in this regard.” The church had saved itself a substantial sum of money in renovation work that would have to be repeated every few years due to unhandled moisture.

Churchgoers used to suffer from mold on the walls and a musty smell. Now they can attend services undisturbed. The sandstone walls of St. Marein are completely dry again thanks to the Aquapol system.

It was the same story at the Klosterneuburg monastery, near Vienna in Austria. For masterbuilder Franz Maier, belief is an important part of his spiritual life as a Christian, but as the person responsible for the preservation of the old monastery complex, he has his feet firmly planted on the ground. What he cannot see or touch is not true for him.

For two years he had been contemplating the installation of an Aquapol device. He also considered other procedures such as wall sawing or vapor barriers as a solution to rising moisture. In Franz Maier’s experience, these procedures were not merely expensive, they did not promise the desired result. Wet walls had been troubling the Klosterneuburg monastery for several years. Specifically, it contained a very wet vaulted cellar dating back to the 17th century. The room was to be used as a wine cellar. The musty smell and the salt crystals on the partly flaked-off plaster rendered the cellar unusable without a thorough drying out.

On the ground floor the moisture had crept up the walls to nine feet in places. Aquapol boldly proclaimed its ability to solve the problem, and Franz Maier decided to give it a try. The aim was to dry out the walls, about three feet thick, as thoroughly as possible without any interference into the basic structure of the building and with no vertical water barrier from the outside. The necessity to economize was probably the main reason why Franz Maier decided in favor of the Aquapol device. It was a resounding success. Just six months after the installation, the room climate and masonry moisture were significantly improved. After one year the drying out process was almost completed. The building is now thoroughly dry.

Basilica San Nicola.pdfThe story is repeated at Basilica San Nicola in southern Italy, a church which holds wide religious significance across Europe as a place of pilgrimage. The church was built between 1087 and 1197 and has suffered the depredations of time and water, creating an inhospitable atmosphere for congregants and visitors. Aquapol came to the rescue once again – as it has done in scores of churches and historical buildings – drying out the church structure to the point where the humidity was vastly reduced and mold eliminated. With the walls now dry, Basilica San Nicola has once again revealed her beauty and magnificence to the faithful and visitors alike.

Among other famous buildings using Aquapol technology are the Vatican, museums, parliament buildings and historical sites. In Europe, the system has been installed in in such notable historical sites as the Budapest parliament building, the Joseph Haydn Museum in Austria, the Greek Oriental Church in Vienna, and Schlatt Castle in Germany. There are also several installations in the U.S., including the Celebrity Center in Nashville, Tennessee.

Aquapol USA sales executive Warren Bruckmann says a common problem in historical buildings in the U.S. is the fact that vapor barriers (intended to keep moisture from rising through the ground and into the walls) tend to deteriorate with age. “Once the vapor barrier has been punctured or degraded, there is nothing to stop the water rising from the ground. Traditional methods of handling this do not last, and building owners find they have to fix the same problem every few years. In fact, all they are doing is masking the problem, because rising moisture attacks the masonry and eventually weakens the foundational integrity of the building. This is why Aquapol is such a revolutionary solution.”

The Aquapol technology is based on long-lost discoveries of scientific genius, Nicola Tesla (1856-1943), inventor of the alternating current, fluorescent lamp, radio and wireless communications. The Aquapol inventor, Wilhelm Mohorn, came up with the solution after observing Tesla’s discoveries concerning the properties of water and naturally occurring energy fields within the earth and air. Mohorn was given Austria’s highest award, the Kaplan medal, for his research and invention of the Aquapol system.
