What To Expect: Installing a Foundation on a New Home

Building a new home is an exciting journey, and one of the most crucial steps is installing the foundation. A strong, well-built foundation ensures the stability and longevity of your home. But what exactly does this process involve? When does it happen? And who oversees it? In this guide, we’ll walk you through everything you need to know about foundations on new homes so you know exactly what to expect.


What Is a Foundation?

A foundation is the base of a home. It transfers the weight of the entire structure to the ground, keeping everything level and secure. Without a solid foundation, a house can shift, crack, or even become unsafe over time.

There are several types of foundations on new homes, each designed to fit different climates, soil conditions, and construction needs. The most common foundation types include:

  • Slab Foundations – A single, thick layer of concrete poured directly onto the ground. These are common in warmer climates where deep frost isn’t a concern.
  • Crawl Space Foundations – A raised structure that creates a small space beneath the house, allowing for easy access to plumbing and electrical systems.
  • Basement Foundations – A deeper foundation that provides additional living or storage space beneath the home. These are ideal for colder climates.

Choosing the right foundation depends on factors like soil stability, weather conditions, and budget. Regardless of the type, every foundation must be built with precision to support the home for generations.


When Do Foundations Get Installed?

The installation of foundations on new homes happens early in the construction process. It typically occurs right after excavation and before any framing begins.


How Are Foundations Completed?

The process of completing foundations on new homes involves several critical steps. Each phase ensures that the foundation is strong and long-lasting. Here’s how it’s done:

  1. Forming and Rebar
    • Forms are built to make a mold for the concrete to fill.
    • Rebar (reinforcing bar) is added to the forms to hold the concrete together in tension.
  2. Pouring the Concrete
    • Once the forms are in place, workers pour concrete into them.
    • Vibrating tools remove air pockets, preventing weak spots.
    • The surface is leveled and smoothed for a uniform finish.
  3. Curing the Concrete
    • Concrete doesn’t dry—it cures. This process takes about 7 to 28 days.
    • Proper curing prevents cracks and ensures maximum strength.
  4. Waterproofing and Drainage
    • A waterproof membrane is often applied to basement foundations.
    • Drainage systems, like French drains, may be installed to direct water away.

With these steps completed, the home is ready for the next phase—building up from a strong, stable base.


Who Is in Charge of Foundations on New Homes?

Many professionals are involved in the foundation process. Each plays a key role in ensuring that foundations on new homes are built correctly.

  • Architects and Engineers – They design the foundation based on the home’s structure and local building codes.
  • General Contractors, such as Kimball Construction – They oversee the entire construction project, including the foundation work.
  • Concrete Specialists – Experts who mix, pour, and finish the foundation concrete.
  • Building Inspectors – Local officials who ensure the foundation meets all safety regulations.

Since the foundation is such a crucial element, careful coordination among these professionals is essential. Proper planning and execution lead to a secure, long-lasting home.


Frequently Asked Questions

1. How long does it take to install a foundation?

The process typically takes one to three weeks, depending on the type of foundation, weather conditions, and curing time.

2. What factors affect foundation costs?

Costs vary based on foundation type, soil conditions, excavation requirements, and material prices. Basements tend to be more expensive than slab foundations.

3. Can foundations be installed in winter?

Yes, but extra precautions are needed. Heated enclosures, additives in the concrete, and special curing methods help ensure a strong foundation even in cold temperatures.

4. What happens if a foundation isn’t built correctly?

Improperly built foundations can lead to cracks, shifting, or water damage. This is why hiring experienced professionals such as Kimball Construction is critical.

5. How do I know which foundation type is best for my home?

Your contractor or structural engineer will recommend the best foundation based on your location, soil type, and home design.

6. Can I make changes to the foundation after it’s built?

Modifications can be costly and complicated. It’s best to finalize your foundation plan before construction begins.
