Naperville Triscuit

Naperville IL was found­ed in 1831 and known as Naper’s Set­tle­ment. It remained a most­ly rur­al farm town even though it was incor­po­rat­ed as the City of Naperville in 1890.

Because it didn’t expe­ri­ence a sig­nif­i­cant pop­u­la­tion growth until the 1960s, Naperville was a bit of a late bloomer, large­ly passed over by the pop­u­la­tion and hous­ing boom that fol­lowed World War II. When its time came, though, Naperville caught up in a hur­ry, con­struct­ing 28,000 new homes in the city between 1980 and 2000.

Today, Naperville is the fifth largest city in Illi­nois with a pop­u­la­tion of more than 143,000. Res­i­dents enjoy excel­lent schools, parks and libraries and a well-pre­served and thriv­ing down­town area. Numer­ous col­lege cam­pus­es are in or close to Naperville and the city boasts of a num­ber of large busi­ness­es, includ­ing the Nabis­co bak­ery that is the sole source of Triscuits for the U.S.

There are more than 45,000 homes in Naperville and, although most are on the new side, home­own­ers there still grap­ple with main­te­nance issues and prob­lems, includ­ing wet basements.

Repair­ing a Wet Base­ment in Naperville

Of course, just as for homes in oth­er Chica­go sub­urbs of the same vin­tage, like Evanston and Oak Park, Naperville homes with wet base­ments are treat­ed on a case-by-case basis but there are sev­er­al com­mon remedies.

Crack Repair – Most homes in Naperville are new­er, so the pre­vail­ing type of foun­da­tion is poured con­crete; the most com­mon source of seep­age in this type of foun­da­tion is a non-struc­tur­al crack in the foun­da­tion wall. The best way to per­ma­nent­ly repair such a crack is by inject­ing it with expand­ing polyurethane from inside the base­ment. The polyurethane fills the crack to the out­side soil and remains flex­i­ble when cured to pre­vent minor foun­da­tion move­ment from caus­ing the crack to re-open.

In a fin­ished base­ment, the crack can be repaired on the exte­ri­or by dig­ging a small hole next to the foun­da­tion at the site of the crack and fill­ing it with sodi­um ben­tonite clay. The clay sets up a pli­able but imper­me­able bar­ri­er against ground water on the pos­i­tive side” of the foun­da­tion wall.

Inte­ri­or Drain Tile – Anoth­er com­mon source of seep­age in Naperville homes is when hydro­sta­t­ic pres­sure in the ground below the foun­da­tion forces water through the cove joint and/​or cracks in the base­ment floor. Installing inte­ri­or drain tile, per­fo­rat­ed pipe buried in a bed of washed grav­el below the base­ment floor, alle­vi­ates this pres­sure and car­ries ground water away to a sump pump for removal. Prop­er­ly installed, inte­ri­or drain tile requires no maintenance.

Exte­ri­or Water­proof­ing – Water can also enter a Naperville base­ment through mor­tar joints, porous con­crete or mason­ry or over the top of foun­da­tion walls. This seep­age can be stopped or pre­vent­ed by apply­ing an exte­ri­or water­proof­ing mem­brane, a thick coat­ing of asphalt-mod­i­fied polyurethane applied with a trow­el to the out­side of a foundation.

If large amounts of ground water are present, the mem­brane can be aug­ment­ed with exte­ri­or drain tile and drainage board to pro­tect the mem­brane and chan­nel water downward.

Regard­less of the best method of repair, a Naperville home­own­er with a wet base­ment needs the ser­vices of a pro­fes­sion­al base­ment water­proof­ing con­trac­tor that knows Naperville’s homes. At U.S. Water­proof­ing, we’ve been fix­ing wet base­ments around Chica­go for 56 years and we’ve already helped hun­dreds of Naperville home­own­ers turn their wet base­ments into dry, healthy ones. Why not ask for a free con­sul­ta­tion?
