Water­proof a Base­ment in NW Indi­ana Quick­ly and Cost-Effectively

Homes in NW Indi­ana suf­fer from base­ment water prob­lems just like homes every­where but there are sev­er­al fac­tors spe­cif­ic to the area that affect the sever­i­ty of the prob­lem and the nature of the repair.

High Water TableWater table” is the term used to describe the lev­el of water in the soil in a par­tic­u­lar area. In dry areas, even those that seem com­plete­ly arid, there is water in the soil but at a very low lev­el. Near large bod­ies of water, the water table is usu­al­ly very high, as it is in NW Indi­ana, a locale that sits on the shores of Lake Michi­gan. A high water table increas­es hydro­sta­t­ic and lat­er­al pres­sure on a foun­da­tion and can make leaks hap­pen more frequently.

Sandy Soil – The soil in NW Indi­ana is gen­er­al­ly high in sand con­tent, which means that the soil drains quick­ly but also that the soil doesn’t pro­vide the same sup­port for the foun­da­tion offered by a denser soil like clay. Also, when sandy soil is wet, it is much heav­ier than oth­er soils and increas­es lat­er­al pres­sure on foun­da­tion walls that can lead to cracks and leaks.

Block Foun­da­tions – The most com­mon type of foun­da­tion in NW Indi­ana is one con­struct­ed of con­crete blocks, also known as cin­der” blocks or CMUs. These blocks are typ­i­cal­ly more porous than poured con­crete and have numer­ous mor­tar joints that can admit water to the base­ment when cracked or eroded.

Even with these con­tribut­ing fac­tors, it is still pos­si­ble to water­proof a base­ment in NW Indi­ana quick­ly and cost-effectively.

Quick and Cost-Effec­tive Base­ment Water­proof­ing in NW Indiana

Water seep­age in a NW Indi­ana home is most like­ly to come from one of sev­er­al sources: floor cracks, the cove joint between wall and floor, cracked or dete­ri­o­rat­ed mor­tar joints or porous con­crete block. The most cost-effec­tive and quick­est to install rem­e­dy for these prob­lems is inte­ri­or drain tile, which will solve the prob­lem in one of two ways.

Inte­ri­or drain tile is a sys­tem of per­fo­rat­ed pipe that is embed­ded in washed grav­el under the base­ment floor. To install it, a foot-wide sec­tion of floor is removed around the perime­ter of either the entire base­ment or the affect­ed area and a trench is dug down to the lev­el of the footings.

A shal­low bed of washed grav­el is poured in and the flex­i­ble drain pipe, encased in a sock” of fil­tra­tion fab­ric is laid on top. The pipe is con­nect­ed to a sump basin at one or both ends and cov­ered with more washed grav­el. The con­crete floor is then patched.

Inte­ri­or drain tile pre­vents seep­age through floor cracks or the cove joint by alle­vi­at­ing the hydro­sta­t­ic pres­sure that occurs under the foun­da­tion and forces water in. It col­lects the ground water that cre­ates the pres­sure and car­ries it to the sump pump for discharge.

For seep­age com­ing through the walls, via either cracked mor­tar joints or porous blocks, the inte­ri­or drain tile is installed with a few vari­a­tions. A small gap is left between the floor and wall to allow seep­age to drain into the sys­tem. This gap can be cov­ered by a plas­tic baseboard.

To pre­vent water from accu­mu­lat­ing in the cav­i­ties of the con­crete block, weep holes are drilled near the bot­tom to allow drainage into the drain tile system.

The home­own­er may also elect to take one more rec­om­mend­ed step, installing a vapor bar­ri­er on the wall to cov­er the seep­age and pre­vent mois­ture intru­sion into the base­ment atmosphere.

Installing inte­ri­or drain tile is not a small job but it is far less cost­ly and dis­rup­tive than doing exte­ri­or water­proof­ing that would require sub­stan­tial exca­va­tion and oth­er labor. A typ­i­cal inte­ri­or drain tile instal­la­tion can be com­plet­ed in sev­er­al days and can be done even in a fin­ished base­ment with a min­i­mum of disruption.

Regard­less of the source of the seep­age prob­lem, a NW Indi­ana home­own­er will require the advice and ser­vices of a pro­fes­sion­al base­ment water­proof­ing con­trac­tor that has worked with con­crete block foun­da­tions and knows the fac­tors that com­pli­cate water­proof­ing in the area. At U.S. Water­proof­ing, we have been keep­ing base­ments dry in NW Indi­ana, as well as in Chica­go and south­east­ern Wis­con­sin, for more than 57 years and have installed lit­er­al­ly miles of inte­ri­or drain tile. Why not ask for our free advice?
