Basement Waterproofing Along I-93: What to Know
The I-93 corridor passes through some of New England’s most historic and heavily traveled communities. Whether you reside in Massachusetts, New Hampshire, or Vermont, many homes in this area feature older basement foundations, some built long before modern waterproofing solutions became the norm. As a result, water issues are common for many homeowners.
Musty odors, damp walls, and pooling water are signs of moisture intrusion that, if left unaddressed, can impact your home’s air quality and weaken its structure.
This page explains what homeowners need to know about basement waterproofing along I-93, including local risk factors, effective solutions, and how to choose a trustworthy basement waterproofing professional.
Top Reasons Basements Flood Along the I-93 Corridor
If you live along I-93, you may wonder why basement flooding is so common, whether in your home or your neighbors’. Here are the top three reasons it continues to affect homes in Concord, Manchester, and Lincoln:
House Age in Concord, NH
As New Hampshire’s capital, Concord has many older homes with original foundations that lack modern waterproofing methods. Cracked walls, poor exterior drainage, and worn-out sump pumps are common culprits behind water in basements and structural damage caused by water.
Densely Populated Neighborhoods in Manchester, NH
Manchester’s highly populated area makes managing basement water a challenge. Many properties have limited space for exterior drainage and proper grading, which makes interior waterproofing critical for preventing a wet basement.
High Water Table in Lincoln, NH
Lincoln, NH, has high water tables and significant runoff during snowmelt due to its proximity to the White Mountains. Basements here are especially vulnerable during the spring and fall, increasing the need for year-round moisture control.
Just because your home experiences basement flooding doesn’t mean you have to live with it. Effective solutions exist. Let’s take a look at a few.
Basement Waterproofing Along I-93: Effective Solutions
Live in Manchester and need basement waterproofing along I-93? Here are proven New England basement solutions worth considering:
Interior Drainage Systems in Northern New England
Interior drainage systems in Northern New England are one of the most effective ways to manage basement water and prevent flooding. These systems, installed along the interior perimeter of the basement floor, collect and redirect water toward a sump pump for removal. They’re especially popular in Concord and Manchester, where tight lots and aging foundations make exterior drainage less feasible.
Sump Pumps and Backup Systems
A reliable sump pump is your basement’s first line of defense against water in basements. Sump pumps collect water from the interior drainage system and direct it away from the basement. In high-moisture areas like Manchester and Concord, pairing your pump with a battery backup ensures protection during storms and power outages.
Vapor Barriers
Basement walls made of poured concrete or cinder block can absorb and transmit moisture from the surrounding soil. Vapor barrier installation is applied directly on the walls and/or floors to seal the area and prevent the moisture that causes a wet basement. They work best when combined with drainage systems and other basement waterproofing solutions.
Dehumidifiers
Even after addressing water entry points, basements often retain humidity, especially in older homes or those with limited airflow. A basement dehumidifier removes excess moisture from the air, helping prevent mold growth, condensation, and musty odors. In consistently damp climates like Northern New England, it’s a key part of a comprehensive waterproofing strategy.
Egress Windows
Code compliance and safety standards require egress windows for finished basement bedrooms, but these can be a source of water intrusion if not properly installed and sealed. Installing a code-compliant egress window with a built-in drainage well and cover helps prevent water seepage while maintaining natural light. For homes along I-93 with finished or partially finished basements, waterproofed egress systems offer function and protection.
New England basement solutions are often tailored to your home based on the region’s soil type, climate, and other risk factors. This approach provides the most effective and long-term protection for your foundation and home.
Common Risk Factors Behind Flooded Basements
Waterproofing in Concord NH to Boston MA requires careful consideration of the soil type and land elevation, so each basement needs a tailored approach. The following factors can cause a flooded basement:
Soil Type
Clay soil retains water and can cause hydrostatic pressure, which pushes inward toward the basement, causing bowing walls and foundation cracks. An interior drainage system in Northern New England is beneficial for preventing a wet basement.
Freeze-Thaw Cycles
Frequent freeze-thaw cycles cause soil movement, which leads to cracks in foundation walls and allows water to seep inside. Proactive basement waterproofing installation seals the area and helps prevent water-related damage caused by the frigid winter temperatures.
Storm Impact
I-93 communities often face heavy rain from Nor’easters and hurricane remnants, leading to flooded basements when proper waterproofing isn’t in place. Over time, repeated water intrusion can damage foundation walls, flooring, and stored belongings.

Basement Waterproofing FAQs
Hydrostatic pressure occurs when water-saturated soil presses against your foundation walls, leading to cracks, leaks, and structural damage over time.
Exterior waterproofing solutions like damp proofing for the walls and footing drains are available, but their exposure to the elements can render them ineffective over time. The damp proofing can wear away, and the buried drains can be crushed or clogged.
Waterproofing your basement once so you’ll never have to worry about it is definitely worth the investment. You can’t put a price on your peace of mind.
