Doing Wet Basement Waterproofing in Norridge IL 60706

It’s not really fair to call the village of Norridge a “suburb” of Chicago because suburbs are generally defined as “outlying towns or districts” of a city.  Maybe, since far-flung suburbs are often called “exurbs,” it might be best to coin a new term for Norridge and call it a Chicago “endurb” because the village of just fewer than 14,000 residents is entirely contained within the city limits of Chicago.

Along with its neighbor to the east, Harwood Heights, Norridge is often referred to as an “island in the city.”

Originally known as “Goat Village” due to the presence of a livestock farm and “Swamp” for its mushy terrain, Norridge was an unincorporated subdivision until 1948 when, threatened with annexation by Chicago, it incorporated itself as a village at the last minute.

The postwar 1950’s brought development to Norridge, both in municipal infrastructure and residential construction, with 3,700 of the village’s current 5,800 homes being built in the 1950s and ‘60s.  The village, with its name formed from parts of “Norwood Park Township” and neighboring “Park Ridge,” is the only so-named municipality in the world.

With its majority of 50- and 60-year-old homes, Norridge homeowners are running into the repair and maintenance problems that go along with age, including the need for wet basement waterproofing.

Doing Wet Basement Waterproofing in Norridge

Just as in nearby Des Plaines and Elk Grove Village, homes in Norridge that may need wet basement waterproofing are individually evaluated and diagnosed but there are several commonly used methods that solve most basement water problems.

Interior Drain Tile – A common source of water in any basement is when seepage occurs through cracks in the floor or through the cove joint between wall and floor.  This seepage is caused by hydrostatic pressure under the floor pushing the water in through even the smallest of openings.  This pressure can be alleviated and the seepage stopped by installing interior drain tile, a system of perforated piping that is buried beneath the basement floor in a bed of washed stone.  The drain tile collects the water and carries it to a sump pump to be discharged from the house.  Done properly, interior drain tile never needs maintenance.

Exterior Waterproofing – It is common for poured concrete foundation walls to have porous patches that seep water and to allow water to seep over the top of the wall.  Masonry walls can admit water through cracked or deteriorated mortar joints or through porous masonry itself, usually concrete block or brick.  Stopping or preventing this seepage is as simple as installing an exterior waterproofing membrane, a thick coating of asphalt-modified polyurethane that is applied to the exterior walls with a trowel.  When cured it forms an impermeable water barrier.

If the ground water is especially high around the foundation, augment the membrane with exterior drain tile and heavy-duty drainage board that covers the membrane and channels water downward.

Crack Repair – The most common source of water in a poured concrete basement is from a non-structural crack in the wall caused by settlement or lateral pressure from swollen soil.  The best way to permanently repair these cracks is to inject them with expanding polyurethane from inside the basement.  The polyurethane fills and seals the crack all the way to the outside soil and remains flexible when cured to prevent re-cracking from minor foundation movement.

When the basement is finished or the crack is otherwise inaccessible, it can be repaired on the exterior with sodium bentonite clay.  A small hole is excavated next to the foundation and filled with the granular clay.  The clay absorbs water from the surrounding soil and forms a pliable, permanent barrier against water intrusion.

Regardless of the source of water or the appropriate wet basement waterproofing solution, a Norridge homeowner with basement water problems needs the advice and assistance of a qualified basement waterproofing contractor that knows the community.  At U.S. Waterproofing, we’ve been keeping basements dry all over the Chicago area since 1957, including many homes in Norridge.  Why not ask for our free advice?
