Specific Pathologies of Woluwean Masonry

The Clay Soil of the Valley: A Common Cause of Cracks

In the lower parts of Woluwe-Saint-Lambert, particularly the areas near the Woluwe river, the soil is partially clayey. Clay is a material that swells with moisture and shrinks during droughts. These seasonal movements create stress on the foundations and generate cracks in the walls. They are recognized by their diagonal orientation, often at the corners of openings. A geotechnical diagnosis can confirm the origin of the disorder before undertaking a lasting repair.

Rising Damp: The Problem of Old Basements

The foundations of Woluwean terraced houses from the 1950s to the 1970s generally do not have a horizontal waterproofing barrier. Groundwater rises by capillarity in the brick walls, causing efflorescence stains, swelling of the coatings, and degradation of the paints. Addressing this issue requires intervention on the masonry itself: injection of water-repellent resins, installation of a peripheral drain, or creation of a ventilated crawl space, rather than just surface repairs.

Chimneys and Flues: An Often Overlooked Aspect

Woluwean houses built before 1980 frequently have one or more masonry chimneys. The chimney crowns, flues, and interior linings deteriorate over time. A cracked flue can create risks of carbon monoxide poisoning. Before using an insert or wood stove, an inspection of the flue and, if necessary, its relining or complete reconstruction is essential. We carry out these masonry works in coordination with heating installers.

Masonry and Brussels Urban Planning Regulations

Any modification to the structure of a building in Woluwe-Saint-Lambert (opening in a load-bearing wall, modification of the facade, masonry extension) may require a building permit or a prior declaration. The requirements vary depending on the planning zone and the road concerned. Some residential areas of Woluwe are subject to specific regulations regarding facade materials. We verify the applicable obligations for your plot before starting and prepare the administrative files if necessary.

Masonry Work in Occupied Housing

Opening a load-bearing wall or repairing a foundation does not always require vacating the residence. With careful shoring, protection of adjacent areas, and a precise schedule, most structural interventions can be carried out in occupied housing. The duration for creating an opening in a load-bearing wall is generally two to three days, including shoring and masonry finishing. We plan the most impactful phases on consecutive days to minimize disruption.
