Leak in your Foun­da­tion? Repair It Now Before It Gets Worse

It’s dif­fi­cult to pick any one part of your home as the most important.

Walls and floors? Obvi­ous­ly important.

Roof? Of course.

Win­dows and doors? Yes and yes.

A home is like an organ­ic sys­tem where all parts work togeth­er to pro­vide shel­ter, warmth and com­fort, so no indi­vid­ual piece of the sys­tem can func­tion with­out the oth­ers. How­ev­er, an argu­ment can be eas­i­ly made that the foun­da­tion is the basis of it all and, with­out it, the rest of the home would be robbed of a sta­ble base that sup­ports the entire thing.

Most home­own­ers would nev­er ignore a sunken floor, leak­ing roof or bro­ken win­dow but many will over­look a leak in the foun­da­tion until it threat­ens the home­’s sta­bil­i­ty. There are sev­er­al good rea­sons to repair a leak in the foun­da­tion before it affects the entire home.

Why a Leak in a Foun­da­tion Must be Repaired Promptly

Foun­da­tion leaks usu­al­ly hap­pen due to pres­sure in the soil out­side that is caused by water. When soil around the foun­da­tion walls becomes over-sat­u­rat­ed, it swells and push­es inward on the struc­ture. This caus­es cracks in poured con­crete walls and in the mor­tar joints of mason­ry walls and the water is the forced in through these cracks.

Water pres­sure under the base­ment floor can also cause cracks that leak.

Some­times, foun­da­tion leaks occur with­out cracks, such as when hydro­sta­t­ic pres­sure below the foun­da­tion forces water into the base­ment through the cove joint, a tiny aper­ture cre­at­ed when foun­da­tion walls are poured or built.

Of course, leaks in a foun­da­tion can vary in sever­i­ty from a tiny seep­age to a flood­ed floor but one thing is true of any of them – left unre­paired, they spell trou­ble. Here are some rea­sons why foun­da­tion leaks shouldn’t be ignored:

Increased Humid­i­ty – The pres­ence of water in the base­ment, even a small amount, increas­es humid­i­ty, in both the base­ment and in the liv­ing space above. Not only does this cre­ate an uncom­fort­able atmos­phere with­in the home but it forces HVAC sys­tems to work hard­er and longer, espe­cial­ly air-con­di­tion­ing, to remove the humid­i­ty from the air. The result? Big elec­tric bills.

Mold Mold spores are so com­mon that they exist in many places, includ­ing base­ments, where they can lay dor­mant for long peri­ods of time. Mold requires three things to thrive and two of them, warmth and food, are present in just about every base­ment. (Food can be any­thing organ­ic – wood, dry­wall, card­board box­es, etc.) Add water from a leak in the foun­da­tion and mold spores will spring to life, caus­ing dam­age to sur­faces on which they grow and cre­at­ing a haz­ardous atmos­phere as they are drawn upwards into the home, ether by HVAC sys­tems or the stack effect” that moves air upward inside a structure.

Air­borne mold spores can cause or exac­er­bate res­pi­ra­to­ry con­di­tions among the home’s residents.

Wors­en­ing Dam­age – Leaks in foun­da­tions, unfor­tu­nate­ly, don’t heal. Left unre­paired, they can only get worse and allow more water to enter the base­ment. In con­crete block foun­da­tions, for exam­ple, water that enters through cracks in mor­tar joints often finds its way to the cav­i­ties in the blocks them­selves, fill­ing them up and allow­ing water to actu­al­ly seep through the rel­a­tive­ly porous block walls over time.

So, what’s the pru­dent home­own­er to do when he or she spots the begin­nings of a leak in the foun­da­tion? Call a base­ment water­proof­ing pro­fes­sion­al to assess the prob­lem and rec­om­mend a per­ma­nent and cost-effec­tive repair that will pre­vent any of the above consequences.

At U.S. Water­proof­ing, we’ve been help­ing home­own­ers in the Chica­go and north­west Indi­ana area with foun­da­tion leaks since our found­ing in 1957 and we have more than 300,000 sat­is­fied cus­tomers. Why not ask for our free advice when you spot a leak in your foundation?
