Preserving History While Protecting Your Home: The Art of Waterproofing Sudbury’s 18th Century Foundations
Sudbury, Massachusetts, stands as a testament to American colonial heritage, with the Loring Parsonage (c. 1730) and the First Parish Meetinghouse (1797) representing the architectural treasures that define this historic community. Incorporated in 1639, the boundaries of Sudbury included (by 1653) what is now Wayland (which split off in 1780, initially as East Sudbury), and parts of present day Framingham, Marlborough, Stow and Maynard. For homeowners fortunate enough to own these historic properties, protecting their foundations from water damage while maintaining structural integrity presents unique challenges that require specialized expertise.
The Unique Challenges of Historic Foundation Preservation
Many historic structures stand on foundations made of materials such as fieldstone, rubble stone, or early brick. These were laid by hand, often using lime-based mortar joints that are inherently more porous and softer than modern cement, allowing water to penetrate over time. Stone foundations, common in 18th and 19th-century homes, tend to allow water to seep through if the mortar has degraded or the stones have shifted.
The construction methods of centuries past present specific vulnerabilities. Builders in the past didn’t always focus on achieving proper drainage around the structure to redirect water effectively. They also didn’t prioritize managing moisture from the ground, so features such as footing drains or damp-proofing coatings for exterior walls weren’t standard. 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.
The Importance of Specialized Waterproofing Approaches
Traditional waterproofing methods can actually harm historic foundations. Homeowners are prey to the sales pitch that leaks in the foundation can be stopped by applying a coat of Portland-cement mortar over the decaying mortar, or, worse yet, filling the joints with spray foam insulation to provide a waterproof barrier. These approaches frequently fail within 5-10 years, especially on damp sites. They merely entomb the problem and construct a dam over the mortar joints which forces moisture to accumulate out of sight where it hastens the decomposition of the original lime mortar.
Owners of historic properties often need to strike a balance between preserving aesthetic integrity and protecting the structure from water damage. Fortunately, with careful planning and appropriate materials, it’s possible to achieve both goals. The primary goal is effective waterproofing performance while preserving the home’s original character and structural integrity.
Modern Solutions for Historic Foundations
Effective historic foundation waterproofing requires a comprehensive approach that respects the original materials while providing modern protection. Water must be better controlled, foundations must be patched with the correct mortar and a system that is symbiotic with the heritage structure must be installed. If not brick spalling can occur above grade and foundation deterioration can occur below grade.
We have been able to consolidate many rubble foundations by breaking out the deteriorated mortar and often soil then repointing with an appropriate mix of lime mortar. This approach maintains the foundation’s ability to breathe while providing necessary water resistance.
For comprehensive protection, professional waterproofing may include interior solutions such as vapor barriers and sump pumps may be necessary if exterior excavation is too disruptive or restricted by preservation rules. While sump pumps are a modern addition, they can be hidden or disguised within utility spaces to minimize visual impact.
