Maryland Basement Waterproofing and Foundation Repair

     Eight Signs of a Potential Basement  Waterproofing Problems

 
  1. Damp, Musty Odor – Does the basement smell like a locker room?  Chances are it’s not years of accumulated sweat socks but rather years of water seeping into the basement.  There may be no other signs of water infiltration but the nose always knows.
  2. Mold – Black, white or green, whatever the color, the presence of mold in the basement should cause you serious concerns.  Not only will you have to repair a water problem, you’ll have a mold remediation job on your hands.
  3. Efflorescence – See a white, chalky substance on the walls?  That’s called efflorescence, mineral deposits that leach out of wall cracks and openings where water has infiltrated.  Not serious in itself but a bad sign.
  4. Cracks in the Walls – You may not see signs of water seepage-–yet—but foundation cracks never get better by themselves and it’s only a matter of time before you’ll have to repair them.  The good news is that crack repair is usually the least expensive waterproofing remedy.
  5. Cracks in the Floor – Hairline floor cracks are common sources of water seepage from hydro-static pressure in the ground below.  Large cracks or heaving may be signs of an inadequate floor or more serious foundation problems.
  6. Bowed Walls – If you notice an inward curve or bulge in a foundation wall, particularly one made of concrete block, plan on some repairs-–soon.  Bowed walls will allow water infiltration and may compromise the entire foundation but can usually be fixed with steel bracing.
  7. Water Lines on Basement Windows – Basement windows are meant to let in light and air, not to be aquariums.  Evidence of retained water means the window well drain is either badly clogged or missing.  Either way, there are repairs–-or fish-–in your future.
  8. Water Marks on Walls – If you spot stains from water that ran down basement walls, water has entered the basement over the top of the foundation, probably due to poor grading or exterior sources of infiltration.  If it happened once, it’ll likely happen again.

Foundation & Structural Repair

When groundwater saturation occurs in the freeze-thaw periods of winter, the ground expands, creating tremendous pressure on below ground portions of the foundation walls. This stress eventually fractures the wall.

According to the Home Inspection Census, more than 50% of all basement foundation walls have a good chance of cracking or bowing in the winters to come!

Bowed and cracked basement walls can be very serious signs of structural damage to the foundation. Traditional methods of addressing these issues include using wall anchors systems, steel I-beams, tiebacks, piering, and excavation.

Bowing and Cracking in new and old foundations

Usually, bows, cracks, bulges, and buckling basement and foundation walls happen most frequently in more established structures. However, newer constructed buildings are not immune to quickly developing settling concerns. As soil settles outside the foundation walls at different rates, it expands and contracts with seasonal freezing and thawing processes because of hydrostatic pressure in the water table.

When to call for a Foundation Repair

There are several warning signs that should prompt a call to a professional for an inspection besides a bowed or cracked basement wall. The sooner a repair is made, the lower the repair expense is, and often carbon fiber reinforced polymer materials (CFRP), or other foundation wall crack repair methods of ours, can be used as opposed to more expensive and extensive methods, including excavation. The most common warning signs include:

Cracked Block Foundation – Indicates lateral pressure on the walls. Serious movement is evidenced in stair step and horizontal cracks in mortar joints.

Cracks in Poured Concrete – Typically occurs within 30 days of the concrete curing process. Usually, a very simple repair, however, in combination with other signs could be a more serious sign of settlement.

Cracks in Brick Facing – Cracks can be a symptom of foundation movement. Refrain from cosmetic repairs until a professional foundation repair specialist determines the cause to minimize future expenditures and hassles.

Chimney Cracking or Leaning – Often, chimneys are built on independent footers. Therefore, cracking and leaning usually indicate movement in this particular footer. A more severe problem would be foundation movement disturbing this independent footer. A professional can determine the extent of the concern.

Drywall Cracks – Shifts in the foundation often cause other cosmetic damage inside the building. Drywall cracks around windows, door frames, and in corners are common symptoms of significant foundation movement.

Uneven Doors and Windows – Another typical indication of foundation shifting. Shifting could cause the framework to contort out of square, leading to windows and doors sticking or not opening and closing properly.

Sinking Foundation – Perhaps the most serious sign of settlement. The foundation sinks because it is separating from the building structure. This must be taken care of as soon as possible or may lead to wall collapse.
