Manville sits at the confluence of the Raritan and Millstone Rivers in Somerset County, a location that makes it one of New Jersey’s most flood-impacted communities.
Residents and property owners in Manville understand this reality well; the community was significantly impacted by Hurricanes Floyd in 1999, Irene in 2011, and Ida in 2021, each underscoring the ongoing vulnerability of basements and foundations in this low-lying river community.
Manville’s residential development accelerated in the early 20th century, when homes were constructed throughout First Street, South Main Street, and North Second Avenue–directly on floodplain soils–as the Johns Manville asbestos fiber plant, from which the community takes its name, was developed.
Manville’s entire community sits within or immediately adjacent to FEMA-designated flood zones, and the soils beneath Manville are classified as Udorthents and Raritan series—characterized by extremely poor drainage.
With no provision for long-term groundwater management, homes in Manville have experienced an astounding 127 recorded flooding events since 1903, causing the community millions of dollars in damage over the last century.
United Waterproofing engineered a patent-pending basement waterproofing and foundation repair system specifically designed for the floodplain conditions of Manville.
Using top-of-the-line products, including ⅜” thick plexiglass lids and battery backup systems, you can rest confident that your waterproofing system will hold up during the worst storm events.
Manville’s location at the confluence of the Raritan and Millstone Rivers creates a unique environment in which the subsurface water table rises rapidly during storms. The surrounding low-lying floodplain soils trap this moisture, exerting constant, heavy pressure on your home’s foundation and causing standing water in your basement that can exceed several inches.
Manville homes are uniquely vulnerable to flooding and basement moisture intrusion caused by:
Neglecting these conditions leads to a progressive decline in your home’s structural integrity. You will likely face catastrophic flooding that overwhelms standard pumps, followed by horizontal foundation cracking and slab heaving as the ground expands.
Over time, chronic humidity fuels mold growth, while mineral-laden water causes masonry spalling and efflorescence, ultimately compromising your home’s stability.
United Waterproofing installs complete groundwater management systems calibrated for Manville’s floodplain elevation, saturated alluvial soils, and the high-volume, rapid-onset water events characteristic of the Raritan watershed.
