  • Draining and waterproofing basements: Effective measures against moisture and flooding

    A worn, empty concrete pit with rusty beams, exposed pipes, and draining buckets—one orange and one green—sits against stained, aged walls in a dimly lit basement-like area. www.commaik.de

    Draining my cellar was a lengthy and challenging project that I implemented using various methods to permanently combat damp and mold. From waterproofing with injection methods to installing a pump sump and retrofitting a horizontal barrier – I share my experiences, the challenges and how the measures have proven themselves even under extreme weather conditions. Draining and waterproofing basements: In this blog post, I describe how homeowners can effectively combat moisture and mold to create a dry and healthy basement. Draining a damp cellar was an important step for me to preserve the building fabric and prevent mold growth. In this article, I’ll shed some light on the measures I…

  • Draining the cellar – 1 year later

    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.

    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…

  • New submersible pump defective – draining the cellar

    Two months ago I built a sump pit with a sump pump in my cellar to collect the water seeping into it and further dry out my cellar. A submersible pump with an integrated float switch should then pump the water out via a hose. Unfortunately, things turned out quite differently. The new submersible pump in the pump sump was defective after just a few weeks. Read this article to find out why the pump was destroyed and how the draining process continued.

    I built a sump pump at the lowest point of my house to help drain my cellar in the long term. The water is collected there and pumped out automatically. In this article, I describe how I built the soakaway and what I had to pay particular attention to. I go into the advantages and disadvantages of this method of draining the cellar and of course also write about whether this method works. Drying out the basement of my 120 year old house has been going on for 12 months now. In the interior, I have previously used the injection method to dry out. The areas above the barrier layer…
