Leak Laak (The Hague): find cause and repair

Characteristic of Laak (The Hague): pre-war workers' houses and commercial buildings, with narrow crawl spaces and old drains. Soil and sewers in Laak (The Hague): low-lying with extensive pumping; during heavy rain, water enters cellars and crawl spaces more quickly.

In older properties, pipes are often embedded in floors or walls, sometimes still made of steel or lead. This is precisely where it pays to measure first and only then open up in a targeted way. With a high groundwater level, moisture in a cellar or crawl space is not always a leak. We first measure whether it is mains water or groundwater. Moisture in a cellar, basement or crawl space can come from a leaking pipe, but also from outside through the wall or floor. We first measure which of the two it is before anything is opened up. In commercial premises and greenhouses, pipework often runs over long distances and partly outdoors; frost and wear are common causes of leaks there.

What we most often encounter in Laak (The Hague) in this area: water in crawl spaces and leaking drains under the floor. We also frequently attend for subsided external sewers.
