What Affects Waterproofing in Illinois
The north and northwest suburbs of Chicago are built on flat glacial clay that drains slowly, and many homes have full basements. When heavy rain hits, water has nowhere to go quickly; it collects against foundations, and storm and sanitary sewers can be overwhelmed. Basement flooding from overland water and sewer backups is common after big storms.
The Des Plaines River has flooded neighboring communities several times, including record crests in 2013, and many suburbs have programs that help homeowners install overhead sewers or backflow protection. Freeze-thaw cycles in winter can widen cracks in poured and block walls.
In this area, a waterproofing plan often combines a sump with battery backup, interior drainage, crack repair and sewer backup protection, along with regrading on flat lots where water pools against the house.
What to Check Before You Call
