Welcome to the "International Association for Science and Technology of Building Maintenance and Monuments Preservation",(WTA)

The mission of the international association WTA e.V. is the fostering of research and its practical deployment in the disci-plines of building and monument preservation.

"Radon in the building stock"

With the modification of the Strahlenschutz-Gesetz (Radiation Protection Act) and the Strahlenschutz-Verordnung (Radiation Protection Ordinance) as of 31.12.2018, the requirements of structural protection measures against excessive radon exposure in existing buildings have been met. Particularly in the case of energetic renovation, the radon concentration in buildings increases, since the discharge of the radioactive gas radon is also reduced by improving the air tightness of the building envelope. The working group is to draw up a WTA leaflet that can be a guideline for planners, tradesmen and experts working in the building sector when dealing with the new questions of protection against excessive radon concentrations in common rooms and workplaces in buildings.

WTA receives gold medal

On 10 November 2018, the WTA e.V. will be awarded the gold medal for outstanding achievements in the preservation of historical monuments in Europe at the leading European trade fair "denkmal".
