Germany - The KiTa in Lemwerder has to be renovated due to water damage from the inside and outside.

Description

Due to water damage, the daycare center in Lemwerder has to be extensively renovated both inside and out. The children will be relocated to a container facility for this purpose; The daycare center was completed in 2016. Since then, increased; moisture damage has appeared in the wall base area. This damage has become visible on the plaster and skirting boards, among other things. Several; expert reports unanimously criticize the; base penetrations and the exterior waterproofing. In addition, the building is located deep in the terrain and is exposed to pressing water due to accumulating water. A pollutant report has shown that there is water on the floor slab and the insulation has mold spores. The indoor air in the group rooms is not yet affected, but there is an urgent need for action, as the possibility of mold spores being transferred to the indoor air cannot be ruled out. As the insulation is contaminated, the entire floor structure will be removed and the mold removed. By exposing the floor slab; the approx. 40 floor penetrations can be remediated. Subsequently, a fine cleaning and component drying must take place. During the renovation of the interior, the exterior waterproofing will also be renovated. To do this, the building will be exposed all around the base area, the old waterproofing will be sanded down and new waterproofing will be applied. In addition, the waterproofing of the floor-to-ceiling windows in the lower area will be renewed. Due to the constant accumulation of water, a drainage system will be installed on the outside as part of the renovation to reduce the area exposed to water.As soon as the causes of the moisture ingress have been remedied, the floor will be; rebuilt and the children can move back into the daycare center; The renovation of the kindergarten is scheduled to begin in mid-January 2025, as soon as the children have moved into the interim container facility; One year is planned for the renovation. In January 2026, the children will move back into the daycare center; Before the waterproofing work is carried out, the excavation pit will be created on site. As the groundwater level is very high, a dewatering system will be installed to expose the base. As soon as the excavation pit is exposed, work can begin on the external waterproofing. The façade and insulation must first be dismantled and disposed of professionally. The old waterproofing will be; sealed off. Before the new waterproofing is applied, the; plinth must be thoroughly cleaned.
