  • Draining the basement with a new horizontal barrier – conclusion after 9 months

    A man with gray hair and a thoughtful expression stands in front of a textured beige wall with faded markings, while a large white arrow points to a spot where a horizontal barrier was installed for drying purposes. www.commaik.de

    It is now nine months since our old damp cellar was drained with a retrofitted horizontal barrier – time to take stock. In a building over 100 years old like ours, which was built without the foundation waterproofing that is common today, moisture in the basement is a real challenge. As the rising damp in our cellar became increasingly visible, I installed a new horizontal barrier with injection cream in the thick cellar walls to create a barrier against the ground moisture. In this article, I show in detail what effect the moisture barrier has had, where problems still exist and what other measures seem sensible to keep the cellar…

    In a damp cellar, plastic containers are inserted into holes at the base of a brick wall to dry out the room. A red dehumidifier and various appliances can be seen in the background. www.commaik.de

    I have been working on draining the cellar for a good 2 years. In addition to repairs to the pipe system, ventilation concepts, dehumidifiers, dryers and a pump shaft in the cellar, I also installed a subsequent horizontal barrier with a masonry injection. It is now time for a review and a summary of the individual measures.

  • Dry out the cellar yourself – infrared heating is used

    Plastic bottles attached to a pipe run along a brick wall in a basement or garage, probably part of a drainage system. Nearby is an easel or a whiteboard on blocks with several cables hanging above it. The floor is made of concrete. www.commaik.de

    In order to make the basement rooms of our over 100-year-old city villa usable, I first have to dry them out. The house is partially built into the slope. On the east side the basement floor is at ground level and on the west side about 200 cm below ground level. I have already used various methods for draining. I am currently creating a new watertight horizontal barrier in the masonry using chemical agents such as injection liquid, injection sticks and injection cream. I have already drained the eastern part of the cellar. Now it is the turn of the western part of the building. This time I let my…
