Most people are enamored with the charm and history of older homes, whether they are buying a new one or inheriting their family home. Behind the arched doorways, hardwood floors, and handcrafted details might lie decades of wear and neglect. Foundation damage is one such issue hidden behind the quaint aesthetics that often threatens structural integrity. Neglecting even minor issues can lead to safety hazards and expensive foundation repairs. Ensure you set aside a sufficient budget for maintenance and repairs by consulting professionals, such as Michigan foundation repair experts.
Foundation issues are inevitable in old homes due to factors like outdated construction methods, material degradation, and environmental conditions. These factors slowly deteriorate the structures over decades, leading to a weak, unstable foundation. This blog outlines the key causes of foundation damage, signs to look out for, and the preventive and remediation methods. Old and new homeowners of older homes can take these proactive measures to maintain their homes, ensure their families’ safety, and enjoy peace of mind.
Evolution of Foundation Practices
All foundations face structural issues over time. However, homes built decades ago did not have the strong foundations that today’s homes have. Foundation constructions were not regulated, which led to builders using locally available materials and techniques for foundations. They mostly used shallow footing and did not reinforce the concrete, which meant the foundations did not have the structural integrity of current foundations.
As building codes became more stringent regarding load-bearing capacity, drainage, and seismic and flood resistance, modern homes had to meet the standards to avoid demolition and legal issues. Using steel rebars for reinforcement and waterproofing the basement is standard practice for present-day homes. Even the materials used for construction, like bricks and concrete, have been engineered for durability, strength, and resilience.
Homes constructed in the 1900s are more likely to develop foundation issues, as safety standards and structural requirements were not considered during the construction. Understanding these limitations helps to diagnose and address foundation issues before they become severe.
Causes of Foundation Issues in Older Homes
Older homes often suffer from various issues due to the pressure of weather elements and other environmental factors over the decades. Here are the most common causes of foundation issues in old homes:
Material Degradation
Today’s homes use durable concrete, steel, and engineered wood products that provide structural stability. Materials used in older homes were not as strong and advanced. Builders and homeowners used locally available and cheap materials to build homes. Wood, stone, bricks, and concrete were mainly used for foundation construction. Wooden structures tend to rot, sag, or be infested with pests. Concrete can be weakened by water damage, leading to cracks, crumbling, and spalling. Brick foundations also weaken due to moisture issues and persistent freeze-thaw cycles. Stones are irregular and inconsistent, leading to movement and instability of the foundation.
Soil Movement
Soil movement is one major cause of foundation issues. Homes built in expansive soil like clay are more likely to shift and settle. Weather conditions, organic matter decomposition, and natural processes change the soil composition over time. This reduces the soil’s load-bearing capacity, leading to foundation movement and settlement.
The contraction and expansion of soil with changes in moisture levels affect the foundation. Dry, shrinking soil pulls away from the foundation, creating gaps and causing movement. Similarly, saturated soil creates lateral pressure on the foundation, leading to cracks, leaks, and bowing.
Landscaping Changes
Landscaping also determines the health and safety of the foundation. Changing the plants, structures, and watering patterns drastically affects soil composition and puts pressure on the foundation. Most landscaping projects in older homes are carried out for aesthetic reasons without considering the structural consequences. Foundations of such homes are likely to be damaged and weakened over the years.
Switching to drought-resistant plants reduces water usage, but it also modifies the soil’s hydration level. It causes the soil to dry, shrink, and pull away from the foundation, creating gaps for potential damage. Similar;y, large trees draw a large volume of water from the soil. When they are cut down or removed from the garden, the excess moisture causes soil saturation that exerts pressure on the foundation, causing cracks and structural issues. Roots of large trees can grow over time to shift the soil and even damage the foundation walls.
Weather Exposure
Weather significantly impacts the health and longevity of the foundation. Homes in locations that are prone to heavy rainfall, storms, flooding, and snow are more likely to face foundation issues than areas with a moderate climate. Homes constantly exposed to rain, snow, and freeze-thaw cycles face water intrusion in the foundation. During the dry season, the water dries up and causes the foundation to shrink. This movement weakens the foundation and causes settlement. Temperature fluctuations like freeze-thaw cycles also cause foundation materials to expand and contract, causing the foundation to shift and crack.
Lack of Maintenance and Repair
Regular maintenance and repairs help to preserve the foundation’s longevity. Weather-proof materials or techniques are not used to construct the foundations of old homes. Most homeowners also skip regular inspections and maintenance. They only repair the foundation when there is visible damage or effects on the home’s safety and stability. Neglecting regular maintenance means minor issues like cracks, leaks, and poor drainage lead to major structural issues. With decades of negligence, old homes have issues that cause weak and unstable foundations.
Outdated Building Systems
Most older homes were constructed before modern materials, tools, and techniques were even developed. They lack critical reinforcements that protect the foundation and home from external pressure. Most builders did not use steel reinforcements for concrete, which made it more susceptible to cracks and damage. Effective waterproofing was also not done, which led to frequent water seepage and damage. Most homes were made with shallow footings that are unstable in areas with heavy rainfall and shifting soils. Increased moisture and urban development put further pressure on such buildings.
Failing Drainage Systems
Old homes usually have outdated or failing drainage systems that cannot handle modern-day water drainage. Old and damaged gutters and downspouts might cause water to spill near the foundation instead of away from the home. Degraded pipes and drains can cause water to seep into the home. If the landscape isn’t adequately sloped and maintained, water might flow towards the foundation instead of draining away from the home. Water pooling around the home seeps inside, erodes the soil, and might even cause basement flooding.
What Homeowners Can Do?
Homeowners can follow these simple tips to secure and preserve their home’s foundations.
-
Inspection is a critical step in protecting the foundation and your home. Regularly examine the foundation every few months, especially after severe weather conditions. If you notice cracks or moisture, call a foundation specialist immediately. Schedule professional inspection services every few years to identify warning signs of damage early.
-
Check the gutters and downspouts for debris, keep them clear for proper water flow, and divert water away from the home. Downspouts should be extended 5-10 feet away from the foundation.
-
Large trees should be placed at least 15 feet away from the home to prevent soil saturation and damage to the foundation by the roots.
-
Make sure to maintain a consistent moisture level in the soil. Regularly water the ground during drought and dry seasons.
-
Make sure to address minor issues like cracks, leaks, water pooling, and sagging floors immediately before they cause serious problems.
-
Use proven foundation repair solutions like underpinning, helical, and push piers for settlement issues and epoxy and polyurethane foam injections for cracks and concrete leveling. In case of severe damage, consider getting a full foundation replacement.
-
Older homes face multiple issues over time and require ongoing care. Little investments in prevention help to save thousands in repairs later.
Safeguard Your Old Home
Older houses are very appealing and create cozy homes. However, the years of charm also hide decades of foundation problems. Outdated building techniques, soil movement, landscape changes, and lack of maintenance can lead to severe foundation damage. Proactive preventive measures like regular inspections and timely repairs help to manage foundation issues early. Homeowners should understand their foundation and the causes of damage to handle foundation issues and create a comfortable and safe living environment.
