What Caused My Foundation Damage

When you are looking for a Long Island foundation repair company to handle your foundation problems – your first question is, what caused my foundation repair problems?

Foundation damage can be caused by issues like tree roots infiltrating the foundation wall, a settling foundation causing uneven shifts in pressure on the basement floor and walls, and simply aging concrete. But, one of the most common issues we encounter with Long Island foundation issues is hydrostatic pressure. 

Hydrostatic Pressure & Foundation Damage

Hydrostatic pressure is the lateral pressure caused by water in the soil surrounding your foundation. During heavy rains or melting snow, water seeps into the soil.

As the water seeps down, the soil expands. When the expanding soil comes into contact with your foundation walls, it exerts pressure on them. Given enough time, even the strongest foundation walls will start to give out against the onslaught of hydrostatic pressure. 

As your foundation walls begin to weaken, they will shift, bowing inwards in the middle, tipping or leaning from the top, or shearing near the bottom in the case of CMU (concrete block) or brick walls. As the walls weaken further, they continue to shift, leaving telltale cracks that indicate the underlying problem. 

Basement Wall Cracks to Look Out For in Your Long Island Home

Homeowners throughout Long Island experience cracks in their basement walls, but some are more significant and potentially dangerous. 

Hairline Cracks

Hairline cracks in your basement walls, also called shrinkage or spiderweb cracks, occur naturally in poured concrete or CMU walls and are simply a result of the concrete aging. They occur most often in newly built homes.

Vertical Cracks

Vertical cracks are most often found in poured concrete walls and are generally considered normal, but multiple vertical cracks running parallel or expanding can be a cause for concern. 

Both hairline and vertical cracks are common in Long Island basement walls. Unless you notice the cracks expanding or growing more extensive, they are less a cause for concern than horizontal or stair-step cracks, which require a Long Island foundation repair contractor. 

Horizontal Cracks

Horizontal cracks result from external pressure against your basement walls, causing them to bow inward. You can also see these cracks, such as basement walls tipping or shearing. Vertical cracks will likely grow larger, often letting water leak into the basement. 

Stair-Step Cracks

Stair-step cracks run along the blocks in CMU or brick wall fascias, damaging the mortar joints holding the block walls together. 

Both horizontal and stair-step cracks are more severe issues that will likely continue to grow – you need to call a Long Island foundation repair company.

Foundation Problems Worsen Over Time

One of the most significant facts homeowners often miss is that foundation problems worsen over time. 

If you see cracks in your foundation walls, especially horizontal or stair-step cracks, you must call a Long Island foundation repair expert. If left ignored, your foundation will continue to weaken, and the cracks will grow larger. 

Eventually, the walls will be at risk of collapse. At that point, you will likely need to pay for a foundation replacement company to visit, and foundation replacement is incredibly expensive. 

Instead of risking collapse and paying hefty fees to replace your foundation, you are much better off tackling the problem as soon as possible by having a foundation repair company, like ACM, visit your Long Island home to correct the issues before they get out of hand. It will save you time, stress, and money in the long run.

Reliable, Minimally-Invasive Foundation Repair Solutions

We provide minimally invasive but effective foundation repair solutions in Long Island, helping homeowners in  Nassau and Suffolk counties. 

ACM installs carbon fiber straps to strengthen your foundation walls and prevent further damage. Carbon fiber is stronger than steel, and the straps provide a quality foundation repair solution without creating an eyesore in your basement. 

One of our Long Island foundation team pros installs the foundation straps vertically flush against your basement wall. As external hydrostatic pressure pushes against your basement walls, the vertical straps absorb the pressure, redirecting it so your basement walls can no longer shift. 

With the carbon fiber system completely installed, your foundation is kept strong and your walls in place, preventing foundation wall bowing, leaning, or shearing. 

Protecting Your Foundation With Waterproofing

Foundation cracks in your Long Island home don’t just cause foundation damage, but they often create basement water problems. As the hydrostatic pressure in the soil surrounding your home pushes inward, creating cracks in your foundation walls, the water will continue moving forward, eventually making its way into your basement, where it can create a host of problems, including water damage, mold, and rot. 

That is the bad news. The good news is that ACM can also help with basement water. Along with expert foundation repair solutions in Long Island, ACM offers complete interior basement waterproofing systems. 

Our installed waterproofing system will collect and remove any water that seeps through your basement wall, keeping your basement safe and dry. On top of this, the waterproofing system helps relieve the hydrostatic against your foundation walls, helping prevent foundation damage. 

If your Long Island home has problematic foundation cracks that leak water, foundation repair and basement waterproofing provide a synergistic benefit to keep your home, you, and your family safe.
