Foundation Issues Can Damage Your Home's Structure

Soil settling, tree roots, water damage, and subpar building techniques are just a few of the many causes of foundation problems.

Piering, slab jacking, underpinning, and soil stabilization are just some methods that can be used to fix a foundation. These procedures aim to further stop the foundation from sinking and secure the building. The strategy employed will ultimately be determined by the specifics of the foundation damage.

Repairing a building’s foundation is a necessary maintenance operation for ensuring the building’s structural integrity. It’s best left to professional foundation repair contractors with the knowledge and tools to identify and fix problems with a building’s foundation.

Foundation Problems Can Compromise Your Home and Your Health

Water damage to a building’s foundation can lead to several issues that threaten the building’s stability. Consequences of water seeping into a building’s foundation include:

Types of Foundations

There are a few different kinds of foundations, such as a pier and beam, a crawl space, or a wood foundation. Soil conditions, construction plan, and cost all play a role in determining the type of foundation to choose. Let’s look at some types of foundations.

Poured Concrete Slab Foundations

The poured concrete slab is a frequent type of foundation for both homes and businesses. Building foundations are created by pouring a single layer of concrete over a flat area.

Although poured concrete slab foundations are sturdy and long-lasting, they are susceptible to water damage. A weak or cracked foundation may result if water is allowed to seep into the concrete. 

As a result, the building’s framework may begin to degrade, resulting in a drooping basement floor, wall movement, and even foundational buckling.

These are some of the most common sources of water damage on the underside of poured concrete slabs:

Waterproofing a poured concrete slab foundation using a sealer or membrane is essential, ensuring appropriate drainage around the foundation and fixing any plumbing leaks immediately. Check out our waterproofing service here!

Crawl Space Foundation

A crawl space foundation is popular in places with unstable soil and high water tables. Construction of a crawl space beneath the first floor of a structure is part of this method. This space provides access to electric, plumbing, and HVAC systems.

Wood Foundation

The use of pressure-treated wood in constructing a foundation is an example of the type of foundation known as a wood foundation. It is frequently employed in regions with expansive soil or high water tables since it is a more practical and less expensive alternative to conventional masonry or concrete foundations.

Wood foundations, when built correctly, can be impervious to the effects of moisture and insects. Wooden foundations can be especially susceptible to water damage in areas like Washington, DC, which has a humid climate and frequently has prolonged periods of rainfall.

Proper drainage around the foundation, fast plumbing leak repairs, and installing a vapor barrier or insulation can reduce the likelihood of water damage to a wood subfloor in Washington, DC.

Pier and Beam Foundation

The piers or blocks of a pier and beam foundation are arranged in a grid, and the beams across them are constructed from wood. Plumbing, electricity, and HVAC systems can all be reached through the crawl space, which is located between the ground and the first level.

Pier and beam foundations are susceptible to water damage if improperly built or maintained. Pier and beam foundations are more susceptible to water damage in Washington, DC’s humid and rainy climate.

Below-Grade ICF Walls

With ICFs, you may construct strong, efficient basement walls. Because ICFs create a favorable environment for curing concrete walls, the foundation they support has roughly twice the compressive strength of a poured concrete slab.

Reinforced concrete 6 or 8 inches thick is usual for ICF bases. Moreover, ICF foundations safeguard against natural disasters, including fire, high winds, and earthquakes. Because they use continuous insulation and have few or no thermal bridges, ICF foundations offer excellent insulation.

An ICF foundation is built by dry-stacking blocks to the desired length and then reinforcing and bracing the structure. The hollow form blocks are filled with concrete by hand by skilled laborers.

A foundation built with ICFs can be put in place quickly and easily. Building using ICFs below ground level necessitates using a waterproof membrane and an effective drainage system to prevent moisture seepage.
