Spalling, or surface scaling, in concrete driveways happens when the top layer of finished concrete, usually polished and smooth, flakes off due to water damage and reveals the aggregate material beneath. This occurrence is prevalent in areas that suffer harsher winters and where concrete is exposed to freeze-thaw conditions. You may opt to fix the spalling on your driveway in Murfreesboro yourself, but if the damage is extensive, installation of an all-new concrete driveway may be necessary.
Use the Right Amount of Material
To prevent your concrete driveway from spalling, you need to start with the proper concrete mix, which comprises a specific ratio of sand, cement, and aggregate to make porous, or air-entrained, concrete. Since water trapped in concrete expands and contracts in freeze-thaw conditions, it needs someplace appropriate to go. Otherwise, the exerted pressure from repeated expansions and contractions will weaken the structural integrity of concrete, causing it to crack and flake. Of course, the best way to ensure the proper mixture is to hire a concrete contractor.
Practice Proper Troweling Techniques
Scaling problems may result from the way wet concrete is smoothed out with a trowel. Troweling is a delicate matter, and one that’s best left to the professionals. Care must be taken not to compress the wet mixture too much or to over-finish it. If the mixture is overworked, excessive moisture will be brought to the surface, and it will cause you trouble once the concrete cures. Also, remember not to add extra water to the wet concrete while troweling. Some people do this to help their trowels glide across the sticky surface. However, this practice will inevitably cause spalling.
Seal New Concrete with a Waterproof Sealer
To deter spalling, apply a deeply penetrating, water-repelling sealer over your driveway. By preventing water from seeping into concrete in the first place, you will spare yourself from a lot of heartache later. You should seal your driveway every few years as a part of its routine maintenance schedule. Furthermore, you should consult a concrete contractor if you have any concerns or if you need your driveway surfaces restored.
Concrete is a versatile and durable building material that can be used for a variety of applications. From concrete patios to concrete slabs, there are many different places where you may choose to use concrete around your home. When you are planning a building or renovation project that involves concrete installation, you will have several different types of concrete to choose from. A company offering concrete driveways near Murfreesboro can help you select the right type of concrete for your project. Read on for an overview of the different types of concrete mixes.
Normal Weight Concrete
Normal weight concrete is a concrete mix that is used in many different types of construction projects. This type of concrete is composed of cement, aggregate, and water. When this concrete mix is poured, it will set in as few as 30 minutes. Normal weight concrete is appropriate for projects that are not weight bearing, such as driveways and patios.
High Strength Concrete
When a concrete surface will be bearing heavy loads, high strength concrete may be used. This concrete mix uses a lower ratio of water to concrete in its mixture. IN addition, super plasticizers are added to the mixture to enhance workability. Since more concrete is present in the mix, high strength concrete is much more durable than its normal weight counterpart.
High Performance Concrete
High performance concrete offers properties of excellent durability, workability, and longevity. When mixing high performance concrete, a concrete contractor will typically add additional super plasticizers into the mix. These additives allow a cement mixture to become highly workable, without the addition of extra water.
Air Entrained Concrete
If a concrete surface will be exposed to extremely cold outdoor temperatures, air entrained concrete may be the best choice. This concrete mixture contains extra air bubbles, which allow the concrete to safely contract and expand with temperature changes. Air entrained concrete is one of the exciting new updates to the field of concrete mixes.

The spring season is nearly here, and now is a great idea to plan outdoor renovation projects for your home. Concrete patios can be easily added to many different properties, and the durability and versatility of this concrete surface will provide you with the perfect outdoor living space. When you plan a concrete installation from a concrete contractor serving Murfreesboro , a technician will construct your patio in several carefully planned steps. To help you prepare for your patio project, here is an overview of the steps of installing a concrete patio.
Prepare the Patio Area
Before the concrete patio can be poured, the area must be prepared for installation. The first step of preparing the area is to carefully remove any rocks, branches, or debris from the site. In addition, any plants that are growing in the patio area should be carefully removed. Once the area has been cleared, the next step of preparation is to make sure that the soil is level and completely smooth.
Create a Concrete Form
When the concrete is poured for the patio, it will be shaped by a concrete form. Once the patio site has been prepared, it will be time to create the form for the concrete. First, the outline of the patio is traced into the ground. Next, a technician will use stakes and bendable boards to completely frame the outline. These boards will capture the concrete as it is poured, creating a smooth and even shape.
Install the Concrete
Once the concrete form has been created, it will be time to install the concrete. To provide strength and durability, the concrete can be poured over interlaced pieces of rebar. It is important to pour the concrete smoothly and carefully, so that every part of the form is evenly covered. Before the concrete dries, a technician can use concrete floats and trowels to achieve a smooth and even surface for your patio installation. Once the concrete dries, your patio will be complete.
