Traditional brickwork repair

Brickwork injection and restoration render systems

Nowadays basements in new builds are designed to double up as additional living spaces to be used as an office, or hobby room, guest room or as a wellness area.  Exterior waterproofing with heat insulation is thus planned and done as a matter of course.

However, this can also be retrofitted in existing basements. A well-planned and well-executed restoration can still produce valuable room for everyday use as  a retrofit. Sound advice on retrofits can be found in the WTA guideline  4-6-05/D:

“Retrofitted waterproofing of building parts in contact with the ground” published by the  Wissenschaftlich-Technischen Arbeitsgemeinschaft für Bauwerkserhaltung und Denkmalpflege e.V. [Scientific-technical consortium for the preservation of buildings and historical monuments]. Success based on a good analysis!

Every basement can be renovated. The success of the project depends on the building diagnostics. This includes a damage analysis and assessing the status quo of the building condition plus a test in the laboratory.

The extent of the damage must also be determined. The findings from all these form the basis for a custom-made restoration plan.

Laboratory analysis

To this end samples are taken from the brickwork, ideally from the drill core. These are vacuum sealed and sent to the lab, where they are analysed.

To be determined are the salinity and the moisture penetration levels.
