What happens if water sits on concrete?

Concrete slabs are very porous. This means standing water can easily fill in pores on the surface and eventually break down the concrete. As a result, the concrete may crack, move, or even settle.

How Excess Water Affects Your Concrete Slab

Most people don’t think their concrete slab can be repaired. And others do not want to make the necessary repairs. In reality, concrete is another maintenance project because it is susceptible to damage, especially when exposed to standing water. Every year, homes and buildings experience concrete slab damage due to heavy rainwater and flooding in the Kansas City area. Such situations can have damaging effects on sidewalks, driveways, patios, walkways, concrete floors, and concrete foundations. The good news, however, is that concrete can be repaired. At Polyjacking.com, we make sound decisions and recommendations to solve your concrete slab problems caused by excess water.

Types of Concrete Slab Problems

Concrete slabs are very porous. This means standing water can easily fill in pores on the surface and eventually break down the concrete. As a result, the concrete may crack, move, or even settle. If you suspect concrete slab damage, inspect the surface and look for the following: Concrete cracks – Clay soil expands when wet, and contracts as it dries out. This constant fluctuation causes voids and holes under the concrete slab. As a result, the concrete surface sinks and forms cracks. Clay soil expands when wet, and contracts as it dries out. This constant fluctuation causes voids and holes under the concrete slab. As a result, the concrete surface sinks and forms cracks. Uneven concrete or holes in the concrete – Concrete that is exposed to too much water, harsh weather elements, and other issues can cause soil expansion and movement under the surface. This creates uneven concrete, as well as holes in the surface.

Can you slope existing concrete?

The good thing is that concrete can be repaired. Not necessarily by removing it and redoing it but by adding a slope to its surface after the fact with specialized concrete repair products. The general rule of thumb for a proper slope is that concrete should have a 1/4 inch drop for every foot of length.

Bad concrete can cause a number of problems. One common issue many home and business owners face is poorly sloped concrete. This happens when the concrete contractor that places the original concrete slab either neglects , forgets or simply doesn’t understand the duty of the concrete being installed. Concrete slabs not only provide a clean walking or functional useable surface, they are often used to guide or create drainage for water away from structures and buildings. If you have ever experienced a rainfall followed by leaking near doorways, patio sliding doors, puddles in your garage or patio you may be experiencing the result of poorly placed and sloped concrete that causes water to flow in the wrong direction. The good thing is that concrete can be repaired. Not necessarily by removing it and redoing it but by adding a slope to its surface after the fact with specialized concrete repair products. The general rule of thumb for a proper slope is that concrete should have a 1/4 inch drop for every foot of length. So a typical 10 foot slab should have 2.5 inches height difference at one end to the other. There are many products on the market that are designed to be applied to concrete and can be sloped, and are available in most local construction supply stores.
