Why Your Pre-1980s Home Needs Special Basement Waterproofing Attention

If you’re the proud owner of a home built before 1980, you possess a piece of architectural history with character and craftsmanship that modern homes often lack. However, these aging beauties come with unique challenges, particularly when it comes to basement waterproofing. Understanding the specific vulnerabilities of older homes is crucial for protecting your investment and maintaining a dry, healthy living environment.

The Foundation Story: What Makes Pre-1980 Homes Different

Most foundations built before the 1940s were constructed using materials found at the property’s site. The aggregates mixed into the cement were made from rocks dug up when the footings were excavated. This construction method, while economical at the time, created several long-term challenges for homeowners today.

Many homes built before 1915 in the greater Pittsburgh area and throughout the country have stone or fieldstone foundation walls. Limestone, fieldstone, and brick were common in foundation walls and structures. While these materials provide sufficient support at the time, they are prone to degradation over decades. One major challenge with these materials is their porous nature, making them susceptible to water damage.

Homes built in the 1950s or earlier were built on foundations made from hand-mixed concrete that contains little or no steel rebar to give it extra strength. Due to irregular rebar size requirements, older homes built in the early 1900s were typically poured without rebar. It wasn’t until the 1950s when the American Society for Testing and Materials released set standards for rebar construction in the U.S.

Common Waterproofing Challenges in Aging Homes

Historic homes typically have stone or brick foundations built without exterior damp-proofing materials applied below ground. This is because, at the time of construction, homeowners often do not foresee the use of their underground rooms as livable space. This lack of original waterproofing creates several issues:

Material Deterioration: With time, any sealant or mortar holding the stone walls together can wear away. Water can and will find any way to leak inside through cracks, holes, and gaps in the stone or fieldstone foundation walls.
Poor Drainage Systems: Most homes built before the 1940s didn’t have good drainage or moisture control. Older basements and crawl spaces weren’t equipped with drain tile systems, sump pumps, or vapor barriers, leaving foundations exposed to moisture buildup.
Structural Vulnerabilities: One of the most common issues in 100-year-old basements is cracking. Over time, the natural settling of a house can cause cracks to develop in the walls and floors, providing pathways for water to seep in.

Why Modern Waterproofing Solutions Are Essential

Many Boston homes built before 1950 were constructed without proper waterproofing systems in place. Even if some form of waterproofing was initially applied, it may have deteriorated over time. The materials used for waterproofing in older homes—such as tar or pitch—were not as effective as modern materials like rubber membranes or liquid sealants.

Today’s waterproofing technology offers comprehensive solutions specifically designed for older homes. It can be tricky to waterproof older homes, but our expert team at Baker’s Waterproofing has more than 45 years of experience in working with older homes with stone or fieldstone foundations, as well as 100-year-old basement walls.

Professional Solutions for Historic Homes

Effective waterproofing for pre-1980 homes typically involves multiple approaches:

Interior Drainage Systems: Modern perimeter drainage systems can be installed to capture water before it becomes a problem
Sump Pump Installation: If an owner of a historic home is looking to convert their basement or crawl space into dry storage or living space, installing foundation waterproofing with a sump pump is highly recommended.
Vapor Barriers: These prevent moisture from penetrating through porous foundation materials
Crack Repair: Professional sealing of structural cracks using modern materials

Taking Action: When to Call the Professionals

It is best to consult with a professional that understands historic home waterproofing. Because of the many ways that rainwater can cause foundation leaks in historic homes, it is a huge benefit for homeowners to hire a trained eye to assess the problem and educate them about their basement situation.

Signs that your pre-1980 home needs waterproofing attention include persistent dampness, musty odors, water stains, visible cracks, or any water intrusion after rainfall. Water intrusion issues in historic home foundations can not only lead to mold and unpleasant odors, but can also cause structural damage if leaks go unchecked.

Don’t let the age of your home become a liability. With proper professional waterproofing, your historic home can remain dry, healthy, and structurally sound for generations to come. The investment in quality waterproofing not only protects your property but also preserves the character and value that makes your older home so special.
