Basement renovation

The most common reasons for a basement renovation are the moisture inside the walls. It is noticeable through a musty smell, damp spots on the walls, crumbling plaster and - in an advanced stage - through visible mould. In this context, a quick action is required, because in addition to the impaired building fabric, the health of the house residents is at stake as well. Mould spores can trigger or exacerbate allergies, and, under certain circumstances, they can even trigger serious respiratory diseases.

A damp basement affects the whole building. The moisture pulls into the upper floors resulting into cracks, frost damage, damage to the waterproofing by possibly also reducing the insulation performance. In order to avoid such effects, you should look for the cause of the moisture as soon as possible and dry out the basement.

In older houses or if, in the worst case, there is already a moisture damage, a basement renovation will be required. For this purpose, first of all, an exposure of the outer basement walls will be needed. After that, the defective seal can be replaced quickly and economically with the cold self-adhesive sheet DELTA^®-THENE. In order to make the basement rooms to be habitable and usable, they must have thermal insulation in addition to being waterproofed for reasons of comfort and energy saving. In this context, it is advisable to lay perimeter insulation on the outside of the basement wall. This reduces heat losses by creating a comfortable climate inside the house.

Another important factor is the protection of the seal. In this context, high-performance foundation wall protection and drainage membranes such as DELTA^®-GEO DRAIN QUATTRO and DELTA^®-TERRAXX are used. While DELTA^®-GEO DRAIN QUATTRO is a "specialist" for pressure-sensitive sealing systems such as bituminous thick coatings (PMBC, formerly KMB), the product DELTA^®-TERRAXX is used on all pressure-stable substrates, such as DELTA^®-THENE or perimeter insulation.

In addition to their high robustness, these membranes are characterised by a high drainage capacity, so that seepage or stratified water is quickly drained to the ring drainage by additionally relieve the seal.

In general, as a subsequent renovation of the building seal is very time-consuming, as high-quality, and long-lasting solutions should be selected when planning the measures and a skilled craftsman should be commissioned to carry out the work.
