Local considerations for Laval properties
Laval combines residential neighbourhoods built from the 1950s to today, industrial parks and sectors that are still agricultural. Many properties have a modified service connection (pool, garage, shed, lighting) without an up-to-date plan. The subsoil alternates between plain clay, sand deposits and limestone bedrock close to the surface in some sectors, which changes the ground-penetrating radar reading from one street to the next.
