Rising Damp and Mold in Dutch Homes: Causes and Solutions Through Wall Injection in Rotterdam, Amsterdam and The Hague

Moisture problems are common in many Dutch homes, especially in older buildings with outdated foundations or porous brickwork. Rising damp, mold stains, and a persistent musty smell are signs that residents often notice only when the damage has already become visible. In cities like Rotterdam, Amsterdam, and The Hague—where houses are close together and groundwater levels fluctuate—the issue becomes noticeable even sooner.

Global Bouw supports homeowners in recognizing and sustainably resolving moisture issues on time. With professional wall injection and targeted solutions for moisture control in Rotterdam, we restore the waterproofing of brick walls and basements, preventing further damage to interior finishes, insulation, and the building structure.

Why Rising Damp Occurs

Rising damp occurs when groundwater is drawn upward through brickwork. Many Dutch homes have a missing or worn-out damp-proof course, causing walls to retain moisture over time. This leads to:

• peeling plaster,

• dark spots and mold,

• detaching skirting boards,

• cold and humid indoor areas,

• an unpleasant smell in basements or ground-floor rooms.

Without intervention, the problem worsens because moisture weakens the brickwork and increases heat loss, which further raises energy bills.

How Wall Injection and Basement Waterproofing Solve the Problem

Wall injection is a proven technique within moisture control. During this process, we inject a water-repellent agent deep into the masonry through small drilled openings. The material spreads capillarily and forms a permanent barrier that prevents moisture from rising.

In combination with this, we can also waterproof the basement where necessary. By treating walls and floors, we add an extra layer of protection against penetrating groundwater. This approach is suitable for homes, commercial properties, and heritage buildings where the original damp-proof course is missing or no longer effective. Wall injection and basement waterproofing can be carried out quickly, cause minimal disruption, and often restore the indoor climate within a few weeks.

Benefits for Homeowners

Professional damp proofing in Rotterdam and other cities offers several advantages:

• structural protection against rising damp;

• reduced risk of mold, allergies, and unpleasant odors;

• preservation of plaster and interior finishes;

• improved insulation and living comfort;

• maintaining the long-term value of the property.

If needed, we combine wall injection with plaster repair, basement waterproofing, or façade restoration to ensure a fully dry and safe result.

Moisture Control in Rotterdam, Amsterdam and The Hague

In regions with older buildings—such as Rotterdam-Zuid, Amsterdam-Oost, and the city center of The Hague—we see a clear increase in moisture reports. Due to fluctuating groundwater levels and intensive use of the existing housing stock, both private homeowners and landlords face moisture problems in basements, front façades, and load-bearing walls.

Global Bouw conducts a full inspection, determines the exact cause, and selects the correct injection method based on wall type, moisture percentage, and structural condition. This ensures that the customer receives a targeted and durable solution without unnecessary interventions.
