Concrete Wall

Exploring Basement Challenges in Pennsylvania Homes

Living in Pennsylvania often means residing in older houses, many of which come equipped with basements. It's highly likely that your home, if it's an older one, has a basement. Unfortunately, basements frequently face issues such as water infiltration, and those with water problems in the foundation walls often experience additional structural concerns like bowing, cracking, or leaning.

The construction of these foundation walls varies widely, ranging from materials like sandstone, terracotta, split-face concrete, concrete block (some reinforced, others not and hollow), brick, unreinforced coarse concrete, and reinforced concrete. Additionally, some walls have concrete footers, wood footers, or gravel bases, among other variations.

Given this diversity in construction types, it's our responsibility to offer homeowners the right guidance when they seek solutions for foundation-related challenges, whether it's addressing water problems, structural movements, cracks, or bulging and bowing walls.

In the image below, we measured a wall's bowing at 1.375 inches, using a high-quality laser self-leveling device to confirm the measurement. The homeowner had been informed by a foundation representative that it was bowing over 3 inches and that it was on the brink of collapse around its pivot point if the water problem wasn't addressed and anchor plates weren't installed.

Let us clarify that during our visit in January 2023, the foundation wall was far from collapsing.

In the next two photos, you'll notice the same corner of the house—one taken from the interior and the other from the exterior. The interior photo clearly depicts the buildup of mold, while the exterior picture reveals the root cause, as you might have already guessed. It's the disconnected downspout that channels roof rainwater directly toward the foundation wall. This issue is quite common in many houses, and homeowners are often unaware of the need to address it.


To resolve this issue, it's imperative to repair the downspout and redirect the rainwater away from the foundation walls. This preventative measure is essential in preventing further structural damage. Moreover, addressing this repair is highly likely to eliminate the need for a French drain installation.

Frequently Asked Questions about Foundation Settlement:


Q: Is foundation settlement repair a DIY (Do It Yourself) project? Can I hire a handyman for the job?

A: I often receive these questions from my clients, and the quick answers are both "No." Foundation problems, including settlement, should always be addressed by a professional with the necessary expertise. My recommendation is to hire an unbiased and impartial professional to assess and provide their evaluation and opinion. It's best to avoid salespeople who might push their company's services or products. Each situation is unique, and some issues may require addressing the root cause, while others may involve stabilizing the foundation after correcting the underlying problem.


Q: What is the primary cause of foundation settlement?

A: Foundation settlement can be attributed to several factors, with changes in soil moisture content being a major contributor. Let's explore this further:


Drying: Soils tend to shrink during dry periods, especially in regions with excessive vegetation around foundation walls or where trees draw significant amounts of water from the soil. As the soil dries out, it develops voids (air gaps) that can collapse. When the soil beneath your foundation walls becomes excessively dry, settling occurs, leading to foundation settlement.


Wetting: This occurs during heavy rainstorms or flooding when the soil beneath your foundation becomes oversaturated, particularly with clay-type soils. Poor drainage can exacerbate the issue, preventing water from draining away from the foundation.


Plumbing Leaks: Leaks in water or wastewater pipes due to factors like broken pipes or root intrusion can saturate the soil around your foundation, contributing to settlement.


Voids in Fill Soil: Often, builders disturb the soil when grading the ground before constructing a foundation. Loose fill soil is commonly used and may not achieve the same density as the original soil. Without proper compaction, voids remain in the fill soil, leading to future settlement and affecting the foundation.


Differential Settlement: This form of settlement occurs when one side of the house settles more than others due to localized issues. Factors like the presence of a large tree near one corner, a broken downspout drainpipe, a water leak, or negative grading can significantly impact the soil, leading to differential settlement.


These are some of the major factors contributing to foundation settlement. While we've covered several key elements, it's important to note that addressing every condition is beyond the scope of this educational blog.
