Waterproofing of old buildings

Targeted system solutions for waterproofing of buildings

The effect and durability of waterproofing for buildings depend on different factors. This includes one of the most important factors, i.e. the selection of the correct waterproofing system depending on the type of water load. It is the correct classification of the load that allows sustainable functional waterproofing of buildings.

Regardless of whether the base is insulated, rendered or has visible brickwork, it is one of the parts of a building that is subject to the most loads. In addition to rising damp and splashwater, loads can also be mechanical. Especially if the base is damaged or waterproofing is missing, then serious damage can occur.

If the damaged cellar wall is not freely accessible due to covering or rebuilding work, subsequent interior waterproofing is a good alternative. If the product systems are ideally matched, even high-quality housing can be created in this way.

Over the past few decades, injection procedures for the subsequent production of horizontal impervious layers in the brickwork have established and proven themselves. These are effective, clean and, in particular, inexpensive procedures. The latest development in this field is the revolutionary cream technology.

The main task of the restoration renders according to WTA is to store salts and ensure a dry and salt-free surface. Remmers restoration render systems ideally fulfil the criteria stipulated in the WTA information sheet 2-9-05/D ‘Restoration render systems’.

Very difficult-to-access areas can be waterproofed reliably and permanently using injection technology. It doesn’t matter here whether the cellar is bricked or made of concrete, Remmers always provides a suitable solution.

Structural analysis

Correct structural analysis forms the basis for sustainable and efficient restoration. To develop a suitable restoration concept, the cause and the scope of the structural damage need to be recognised, measured, recorded and documented. The focus is primarily on aggressive salts and building material moisture, as well as physical underlying conditions.
