Top 5 Most Common Basement Waterproofing Problems

When it comes to base­ment water­proof­ing prob­lems, cus­tomers want to know that they are not alone. One ques­tion home­own­ers ask us on a dai­ly basis is, Is my prob­lem unusual?”

And almost every time, we give the same stock answer We’ve seen and solved many of these prob­lems Mr. / Mrs. ____________.”

So where does your base­ment water­proof­ing prob­lem rank?

Drum roll please…

Top 5 Base­ment Water­proof­ing Problems

Num­ber 1: Foun­da­tion Wall Leaks

If you live in Chicagoland and your house was built in the last 20 to 30 years, you prob­a­bly have a poured con­crete foun­da­tion. Wall cracks are far and away the most com­mon source of seep­age in poured foun­da­tions. They hap­pen for a num­ber of rea­sons. For­tu­nate­ly, they are easy to fix. Old­er homes were often built using mason­ry, such as brick and stone. New­er mason­ry foun­da­tions are made of con­crete block and are most com­mon­ly found in North­west Indi­ana and South­ern Wis­con­sin. The mor­tar hold­ing the mason­ry units togeth­er tends to wear away over time, pro­vid­ing an easy path­way for seep­age into your base­ment. This isn’t as eco­nom­i­cal to repair as a crack, but the nice thing is that there are plen­ty of options.

Num­ber 2: Seep­age from Floor

Seep­age from the floor isn’t as com­mon as wall seep­age, but it does hap­pen quite fre­quent­ly, espe­cial­ly dur­ing heavy down­pours. When this hap­pens, the water table builds beneath your base­ment floor, lead­ing to seep­age through cracks in the floor and the cove joint. An Inte­ri­or Drain Tile Sys­tem is usu­al­ly your best bet to resolve that issue. Just don’t be fooled into think­ing water pool­ing on your floor always means it must be com­ing from beneath the floor. It could be com­ing from a wall crack and pool­ing in a low spot. Grav­i­ty can be sneaky. 

Num­ber 3: Sump Pump Problems

A few years ago, we had a pop­u­lar radio spot called Sump-Pho­bia”. The fear of sump pump fail­ure is actu­al­ly quite com­mon. And there’s good rea­son for that — they fail all the time! For­tu­nate­ly, we have an answer. In fact, we have many answers. We offer free sump pump inspec­tions and can cus­tomize a sys­tem to meet your needs. Unless you’re a pro­fes­sion­al, you might not to want tack­le this project your­self

Num­ber 4: Over­flow­ing Win­dow Wells

Win­dow wells are great, espe­cial­ly for let­ting nat­ur­al light into the base­ment. But when they fill with water, look out! An over­flow­ing win­dow well can cre­ate a hor­ri­ble mess. It ranks right up there with sump pump fail­ure as far as the poten­tial for caus­ing dam­age. Drains installed dur­ing orig­i­nal con­struc­tion often fail. At a min­i­mum, do a peri­od­ic check to make sure there isn’t any debris clog­ging the drain. Bet­ter yet, pur­chase a cus­tom win­dow well cov­er. You might also want to try run­ning water inside the well to make sure it drains prop­er­ly. Under­stand this isn’t always a fool­proof test. When it rains, the pipe the drain con­nects into can quick­ly fill up, caus­ing the drain to back up.

Num­ber 5: Grad­ing Problems

Chicagoland is rel­a­tive­ly flat. But there are some areas where it gets a lit­tle hilly – Saint Charles, Palos Hills, and the North Shore sub­urbs along Lake Michi­gan to name a few. If the grad­ing isn’t sloped away from your house, your chances of a base­ment seep­age prob­lem increase sig­nif­i­cant­ly. If your house is sit­u­at­ed on flat ground, make sure the grad­ing does not extend above the top of the foun­da­tion (brick line). Oth­er­wise, water can eas­i­ly seep through the open­ings in the mor­tar. If the grad­ing can­not be cor­rect­ed, in most instances, we’ll use an Exte­ri­or Water­proof Mem­brane to solve the problem. 

If none of these sound like your prob­lem, have no fear. When you have been in as many base­ments as we have, noth­ing real­ly comes as a sur­prise. We’ve water­proofed over 300,000 base­ments over the past 55 years. Yep, we’ve seen just about every type of base­ment water­proof­ing prob­lem there is. Crack seep­age, win­dow well seep­age, floor seep­age, seep­age run­ning down the foun­da­tion wall, seep­age bub­bling up through the floor….Alright, I’ll stop ram­bling like Bub­ba from For­rest Gump (one of my favorite movies).
