Basement waterproofing made easy: How to keep your basement dry and safe

A dry and safe basement is essential for any building to prevent long-term damage and mold growth. Proper basement waterproofing plays a crucial role in this. There are various methods for effectively waterproofing a basement, both from the outside and inside.

Basement waterproofing from the outside

External waterproofing is considered the most effective method for keeping moisture out of the basement. This involves excavating the soil around the building to expose the basement walls. The walls are then cleaned and inspected for damage. A waterproofing layer, such as bitumen or another waterproofing compound, is then applied. This method prevents moisture from penetrating the masonry in the first place.

Basement waterproofing from the inside

If external waterproofing isn't possible, for example, due to adjacent buildings or limited space, the basement can also be waterproofed from the inside. Special sealing slurries or injection methods are used to prevent moisture penetration. This method is particularly relevant in older buildings, where subsequent external waterproofing is often not feasible.

Horizontal barriers against rising damp

Rising damp can move upwards through masonry through capillary action and cause damage. To prevent this, horizontal barriers are installed. One common method is the injection process, in which special sealants are injected into the masonry to create a waterproof layer.
