What are bad foundation cracks

What are bad foundation cracks

You may have seen cracks in the basement of your own home or someone else’s and wondered, “Should I be worried?”

Cracks are very common and will rarely cause any structural issues. While we will be discussing the issue below, you should always have a professional investigate any issues in your house, especially if you are uncertain about the safety of your home.

Cracks can develop due to:

  • settlement
  • improper concrete mixing
  • normal shrinkage
  • tree roots
  • excessive inward lateral pressure
  • expanding soils
  • improper compaction
  • rapid concrete curing

Vertical cracks are usually caused by shrinkage and sometimes by settlement. Unless the cracks are more than 1/4 inch wide, they are not usually symptoms of structural issues. However, because your basement is essentially a cement pond sitting in water, those cracks could let in water. These cracks could leak water from the foundation outside into the basement or crawl space area.  There have been cases where people reported seeing water spurting from these cracks!

Horizontal cracks, usually around the midpoint of your wall, could mean there is lateral pressure and bowing. This can be caused by expanding soils and or hydrostatic pressure. Excessive inward lateral pressure against a block foundation wall will often cause horizontal cracks in mortar joints.  If the adjacent soil becomes saturated with water, the resulting inward pressure can easily overload a wall, resulting in horizontal cracks.  A horizontal crack in the foundation can be a sign of structural damage.

With any foundation crack you see–vertical or horizontal–measure the width and mark the ends of the crack to track the progression of change.  The downside to covered basement walls is you will be unable to tell if structural issues are present. If no water infiltration is present, it is harder to find the signs of foundation cracking.

It is important to identify the actual cause of the problem to avoid fixing the wrong thing.  Hayman Engineering offers Structural Letters which address your specific concerns. We can help you determine whether they affect the structural integrity of your home.

Importance Of a Well-Drained Site

On April 4th, 2013, posted in: Residential by


There are three main reasons to make sure you have a well drained lot:
1 To stop basement leaks,
2 To decrease hydrostatic load on basement walls, and
3 To preserve the bearing capacity of the soils under your foundation.

Your basement is a hole in the ground lined with an imperfect concrete structure–a porous material with cracks, holes, and joints. It is a very cheap pool attempting to keep water out.

There are three things that keep a basement from leaking:

  1. A coating on the basement walls
  2. A proper drain around the bottom of the foundation
  3. A well-drained site

Unfortunately coatings don’t last forever, and the drains can clog or become crushed from improper installation. If these systems break down, then you’ll need to direct water away from the house as best as possible. Wet soil is heavier than dry soil and increases the weight upon your basement walls, which leads to cracking and other damages.

In addition, when the home was built, dirt was excavated, the foundation was built and some of the old dirt was used to fill the gap. Over time that dirt settles, vegetation grows, and soil dries and shrinks away from the structure, changing the grade and causing water to drain toward your house.

Here are some basic changes that almost anyone can make to avoid improper water drainage and subsequent damage to your foundation and basement:

  • Keep gutters clean so water doesn’t overflow and pool at the base of your house.
  • Be sure downspouts are unclogged and drain away from your home.
  • Make simple grade changes near the foundation to direct water away. If possible, the grade should drop 6 inches in the 10 feet nearest the house.

More drastic changes include adding drains or significantly changing the grade of your yard. Curb drains can help redirect some of the water that is coming toward the house from a slope above the property. Another option is a French drain that diverts water away from the foundation and down the hill to either a dry sump, a decorative pond or, the street.

Changing the grade will often involve some kind of excavation machinery. This could be something as small as a rototiller to a large tractor with a blade. If the job requires more than adding dirt near the house you should hire a professional as more harm than help can happen.

If those aren’t enough reasons to change your drainage here’s an added bonus: many plants require well-drained soil. So do your house and plants a favor and get that yard draining right.

Carbon Fiber as a Concrete Solution

On March 28th, 2013, posted in: Residential by

Carbon fibers are only about 1/10th the thickness of a single hair but five times stronger than steel and twice as stiff. These strands are heated to various temperatures depending on the desired product.  At the end of the final heating process, when the impurities are burned off, the strands are left as almost pure carbon which allows for exceptionally strong elemental bonds.

Carbon Fiber Reinforced Polymer (CFRP) has become an increasingly notable material used in structural engineering applications due to its lightweight yet powerful strength.  A four-inch wide carbon fiber strap can withstand over eight times the stress of a steel I-beam even though the strap is less than 1/8th of an inch thick.

CFRP typically has a large impact on strength reinforcement (doubling or more the strength of the section is not uncommon) yet only moderately increases stiffness (approximately 10%), so it is applied to reinforced concrete structures for flexure.

Retrofitting with CFRP has become more dominant in civil engineering; applications include increasing the load capacity of old structures (such as bridges) that were designed to tolerate far lower service loads than they experience today, seismic retrofitting, and repairing damaged structures. Retrofitting is popular because often times repairing a deficient structure using CFRP is more cost effective than rebuilding.

For concrete walls that need to be reinforced, such as basement walls, carbon fiber straps can be used to stabilize and strengthen a wall.  Unlike using beams as reinforcement, which reduces square footage in the basement, carbon fiber straps occupy no extra square footage. Not only is the wall more than doubled in strength, it is also stabilized indefinitely as these straps will not stretch over time due to the carbon fiber’s stiff nature. The straps allow for a solution that requires no excavation, is less intrusive, and is maintenance free.

In many cases you avoid using steel beams to reinforce your basement walls and avoid losing usable square feet.  This allows you to keep the aesthetics of a your basement and do so much more with it.
