In practical terms, concrete can not be lowered. In fact, in more cases than not, solutions to concrete problems do not involve needing to lower slabs. Most concrete trip hazards and misalignment problems develop slowly over time and are the result of concrete settling. However, you might see a problem involving an area of concrete that appears to be “raised”. Take another look. In most cases, areas appearing to be raised haven’t. They are simply alongside a slab or multiple slabs that have actually settled.
In some instances, a concrete slab gets pushed up. Environmental extremes such as freezing, and drought can wreak havoc on concrete; causing individual slabs to move and become out of alignment with one another.
Tree root growth is probably one of the greatest factors when it comes to forcing slabs upwards. Sometimes when concrete is severely raised due to tree roots, the only practical solution is concrete removal so that the roots can be cut away.
There are also situations where concrete slabs have been raised by smaller, slow growing trees that can benefit from raising surrounding slabs in order to correct trip hazards. As a general rule of thumb, we do not suggest raising slabs higher than their original construction. However, it is sometimes simpler and more economical to raise a sidewalk slab that may not have settled in order to eliminate a trip hazard caused by another slab raised slightly by a tree root.
