Concrete and asphalt are building materials commonly used for constructing or repairing sidewalks, driveways, and foundations, and setting posts. Professionals know concrete or concrete mix is a composite material that uses a binder like cement combined with aggregates like stone, sand, and water. When mixed, a pliable material is formed. Once it sets, the material hardens and becomes solid. Asphalt is an affordable alternative that uses tar with aggregates to form a solid surface. Cleaners and sealers will extend the life of your surfaces. Repair patches and compounds will fix and improve the look of concrete or asphalt.
