The foundation of a home or building is one of the most critical design elements, providing support to the entire structure. Your foundation keeps the building anchored in place while also providing the base for constructing walls. Problems in this portion of your construction could lead to serious structural issues in the future, and careful planning and work are important for achieving ideal results. There are many costs to consider in designing and placing your foundation.

It's important to work with a design professional to ensure that your foundation will meet local building codes. Soil samples may be required in preparation for proper architectural work. The location of your prospective structure will also make a difference in the type of foundation to be laid. A deep foundation will require more materials and labor as deeper footings are placed. A shallow foundation will involve less expenses in materials and labor. Your architect will help in determining what type of foundation is suitable to your structure.

Preparing the Land

Before you can install a foundation, your area must be properly prepared. Grading may be required to ensure that the area's surface is flat at the outset. As the area is laid out, stakes and string will be used to mark the outline of the foundation. Digging may be completed by hand or mechanically based on the type of foundation. Footing spaces are dug deeper, and supporting material such as rebar is placed to provide additional strength to the floor and walls of the structure.

Placing the Footings

Upon completion of preparations for your footings, you will need to have them placed or poured. In many cases, concrete is poured in place. However, precast concrete or other footing materials may be used in special settings. Unless you are familiar with large concrete projects and techniques, it's important to work with a contractor to have your footings poured. Proper finishing techniques and mix designs are important for protecting the integrity of your structure.

Pouring the Slab

After footings are completed and before your slab is placed, plumbing and HVAC components may need to be installed. Once the area is laid out correctly, the final portion of your footing installation can be completed. As you have the slab poured, continue to consult with your design professional and with a concrete specialist to limit the potential for cracks and other types of damage. Because of the importance of your foundation in the structure of your building, it's important to work with appropriate construction professionals at all stages.
