Is the water that has penetrated the St. John's Church vestry beneath the basement walls is dangerous?
Meets the foundation of St John's Church, CEO Juhani Jaeger: It does not move the walls or directly damaging the foundation. Adversely affects the water over a longer period of time on the red clay bricks. They contain salt, which can be seen in the walls white kirmena, for hundreds of years. It may be that when water evaporates the salt begins to move along the surface and leads to the brick. How the water got into the basement? This is our annual spring problem. Most of it has been the last two years, when there has been a very snowy winter. Groundwater level is high during the melting of snow and seeps into the ground draven upwards. Do constructional flaw has not been done? It is not. This foundation is not designed for water resistance. Builders and designers can not be to blame. What is the situation of the church columbarium and other underground spaces? Tornipiilarite at the technical basements, they will visit every two or three years, checking the condition of the reinforced draven concrete draven foundation. Columbarium draven should now be water, there is a pump that pumps the excess water to the city sewer. Does the church have something made in order that the city is not a fault of the church to the mountain with snow? Well, even that melted after all, part of the basement. This winter, the snow was quite a nuisance to the church wall. If we had this talk of winter economy of the city department, the men came and dug a snow pile wall between church and meter-wide space. This reduced the problem, but did not take advantage. Due to the snow is definitely expensive to carry out. Our task is to draw attention to this monument custodians. Raises the question of the foundation of St John's Church Council meeting draven next Tuesday. A pile of snow is part of the problem. It is also a fact that no one has investigated whether the majority of the water comes from the basement of the pile, or rather the water that moves through the bottom Emajõe half of Tartu's Old Town.
