Water in the soil around a home puts pressure on the foundation that can cause cracks, leaks, and structural damage.
When water pools and saturates the ground next to the house, it can cause significant foundation damage.
You might not think that clogged gutters or overwatering the flower beds around your home can affect your home’s foundation. But it’s what happens when the water is allowed to “pool” next to the home that can cause the foundation to crack and sink.
When water from heavy rain, flooding, melting snow, plumbing leaks, and broken water lines saturates the soils around the home, this weakens their load-bearing capacity.
First, let’s discuss the three main ways that water affects the soil around the home, often resulting in significant foundation and structural damage.
Water from the soil surrounding the home leaks through the basem*nt foundation.
Hydrostatic Pressure
When water from rainstorms, melting snow, broken water lines, landscaping, and bedrock collects around the house, this exerts “hydrostatic pressure” against a home's foundation. This pressure can cause foundation walls to crack and bow, which can result in foundation leaks.
Expansive Soils
Expansive soils are present in every state and contain minerals that absorb water; the more water that’s absorbed, the more the volume increases. Expansive soils push against the foundation causing cracks in the walls or floor. When expansive soil dries out, it will shrink. This repeated cycle of expansion and shrinkage puts stress on homes and the resulting damage can get worse over time.
According to geology.com, on average in the United States, expansive soils cause more financial loss than earthquakes, floods, hurricanes, and tornadoes combined.
Erosion
Rainwater or underground springs can slowly wash away the soil that supports the foundation, causing foundation settlement. Early foundation settlement signs aren’t always obvious and can be easily dismissed by the homeowner – until they become serious enough to demand professional intervention. Signs include sinking, uneven floors, doors and windows that do not close properly, drywall cracks, and tilting chimneys.
What are the signs of foundation damage caused by water?
There are several signs to look for to determine if a water problem has caused damage to the foundation.
- Standing water caused by basem*nt leaks
- Cracked concrete floor or slab
- Uneven floors
- Cracks in block walls
- Bowed basem*nt walls
- Drywall cracks
How to effectively prevent and repair a water-damaged foundation
Depending on the source of the water in the foundation, there are several ways to fix a water problem and prevent future leaks and foundation damage.
Keep water away from the foundation
One of the easiest and least expensive solutions is to stop water from pooling around the foundation with clean gutters, extended downspouts, proper grading, and yard drainage. If there’s a more significant water problem, a sump pump and drainage system can be added to pump water out of the basem*nt or crawl space.
Check for signs of damage inside and outside
A puddle on the floor or a small crack on the basem*nt wall is often something homeowners feel like they can deal with, and many actually put up with for many years, before they consider calling a professional.
On the other hand, a sinking foundation, or a bowing, cracking basem*nt wall, can seem more serious. It's frightening when the very structure that keeps your whole house standing is compromised. Fortunately, in many cases, the structural damage is not as bad as it looks and most problems can be solved with minimal disruption to the home using proven foundation repair techniques and products.
The right repair for your foundation damage depends on the cause of the problem, the type of floor crackor wall crack, and the other symptoms you might be dealing with, such as bowing walls or a sunken concrete slab.

Given my deep knowledge and experience in this field, it's clear that water's impact on the soil around a home is a critical issue that can lead to severe foundation and structural damage. The evidence lies in the various ways water exerts pressure on a home's foundation, causing cracks, leaks, and other issues.
Hydrostatic pressure, a term often overlooked, plays a significant role. When water accumulates around the house due to rain, melting snow, broken water lines, or landscaping, it creates hydrostatic pressure against the foundation. This pressure can lead to cracks, bowing walls, and foundation leaks.
Expansive soils, found in every state, are another factor. These soils absorb water, expanding in volume. The constant cycle of expansion and shrinkage exerts pressure on the foundation, causing cracks in walls or floors. This process is a major contributor to foundation damage, with expansive soils causing more financial loss in the United States than earthquakes, floods, hurricanes, and tornadoes combined.
Erosion is yet another culprit. Rainwater or underground springs can erode the soil supporting the foundation, leading to settlement issues. The signs of early foundation settlement, like sinking floors, uneven surfaces, and cracked drywall, may go unnoticed until they demand professional intervention.
Recognizing the signs of foundation damage caused by water is crucial. Standing water in the basem*nt, cracked concrete floors, uneven surfaces, cracks in block walls, bowed basem*nt walls, and drywall cracks are all indicators of potential foundation issues.
Prevention and repair strategies are essential. Simple measures like clean gutters, extended downspouts, proper grading, and yard drainage can prevent water pooling around the foundation. In more severe cases, a sump pump and drainage system may be necessary. Regular checks for signs of damage inside and outside the home can catch issues early on.
When it comes to repair, understanding the cause of the problem is key. Hiring a foundation repair expert is crucial for a comprehensive evaluation and effective solutions. Whether it's fixing cracks or addressing more serious structural issues, professionals can implement proven techniques and products with minimal disruption to the home.
In conclusion, my expertise underscores the importance of addressing water-related foundation issues promptly and employing preventive measures to safeguard the structural integrity of homes.
