Soil subsidence - Vulnerability of buildings due to subsidence (2019)

Description

This map gives an indication of the vulnerability of dwellings to subsidence. This indication is determined on the basis of the settlement sensitivity of the subsurface and the foundation of the buildings. Sensitivity to setting The Soil Descent Alert Cards have been used for setting sensitivity. The soil's susceptibility to settlement is divided into three classes: Niet bodemdalingsgevoelig Bodemdalingsgevoelig Sterk bodemdalingsgevoelig An explanation of these maps is included in the layer Total maps Soil subsidence PZH. Foundation Detailed foundation data are not yet available at national level. The age of the buildings is available in the Basic Administration Addresses and Buildings (BAG). Age gives a first indication of the foundation type: Bebouwing van vóór 1950: Foundation on steel or on wooden poles. Steel foundations are particularly vulnerable to subsidence, but old pile foundations can also be vulnerable. Poles that are not deep enough can sink (negative adhesive) when the soil is recessed. Before 1950, pine wood was often used instead of pine wood. Pine wood is more susceptible to bacterial damage, even if it is not dry. Bebouwing van tussen 1950 - 1970: From 1950 onwards, probes were usually first used to determine the appropriate foundation type and pile depth. The foundation was therefore better than before 1950, but during reconstruction the building quality was generally worse than after 1970. Bebouwing van na 1970 : Houses and piles are basically of good quality. Vulnerable buildings due to subsidence Based on the settlement sensitivity and foundation indication, the buildings are divided into three classes: Niet of nauwelijks kwetsbaar: Alle panden op ondergrond met klasse Niet Bodemdalingsgevoelig Panden van na 1950 op ondergrond met klasse Bodemdalingsgevoelig Panden van na 1970 met klasse Sterk Bodemdalingsgevoelig Kwetsbaar: Panden van voor 1950 op ondergrond met klasse Bodemdalingsgevoelig Panden van 1950 tot 1970 op ondergrond met klasse Sterk Bodemdalingsgevoelig Zeer kwetsbaar: Panden van voor 1950 op ondergrond met klasse Sterk Bodemdalingsgevoelig
