Franklin, located in Sussex County, is known as the “Fluorescent Mineral Capital of the World,” with a mining legacy that stretches back more than 250 years.
The region was once home to some of the richest zinc ore deposits in the country, drawing mining companies, workers, and skilled tradesmen from across the northeast.
The operation of the Franklin Mine and Sterling Hill Mine shaped the entire landscape, from housing layouts to local transportation routes — the mineral specimens discovered here are now showcased worldwide at the Franklin Mineral Museum.
In the late 19th and early 20th centuries, Franklin became a thriving company town, with neighborhoods built around the mines, rail yards, and processing facilities.
Many of the older homes in these areas still stand today, featuring stone, brick, and early poured concrete foundations that predate modern waterproofing techniques.
While these historic homes contribute to Franklin’s history and character, they also come with unique structural and moisture challenges that require specialized protection.
Franklin’s mining history and hillside terrain have contributed to challenging soil and groundwater conditions.
The borough receives around 48 inches of annual rainfall and 38 inches of snow, and its dense clay and mineral-rich soils hold moisture against basement walls.
Many homes also sit near former mine drainage paths, where groundwater pressure is naturally higher.
United Waterproofing installs a patent-pending waterproofing and foundation repair system designed specifically for Franklin’s underground water movement and soil behavior.
Franklin’s unique mineral-heavy soil absorbs and holds moisture longer than normal soil, leading to several moisture-related issues in basements and crawl spaces, such as:
These soil chemistry & pressure issues require special consideration to keep basements dry. Dehumidifiers and French drains aren’t enough; only true foundation drainage and structural basement reinforcement can protect against ongoing moisture pressure in Franklin, NJ.
United Waterproofing designs systems that intercept moisture before it reaches the basement concrete, preserving both the structure and indoor air quality.
