This video features a 2018 ACM job at a home near the south shore in Amityville, NY. Before our crew got there, the basement regularly took on several inches of standing water after storms, leaving the space unusable and creating a musty, moldy environment.

South shore homes face some of the toughest waterproofing challenges on Long Island due to proximity to the water, high water tables, and storm surge risk. Watch the video to see the step-by-step process ACM used to manage the water at this property and restore the basement as functional living space.

If your basement floods after every storm, the fix is rarely one product or one quick repair. Schedule a free inspection with ACM to find out what your home actually needs.

The Importance Of Water Management in Long Island

Why Long Island Basements Need Water Management, Not Just Waterproofing
In this video, ACM owner Mark McAlpin explains one of the most important concepts in keeping Long Island basements dry: in many cases, the real solution is not waterproofing in the traditional sense, but water management.

Long Island’s high water table, clay-heavy soils inland, and sandy soils near the coast create water pressure that standard waterproofing methods often cannot handle. Sealing a wall does not address the water pushing through it. Real solutions start with understanding how water moves around your foundation and managing it through proper drainage, sump systems, and grading.

If you are dealing with a wet basement and want a real diagnosis rather than a quick patch, schedule a free inspection with ACM.

Surface Waterproofing in High Water Table Areas

This video features a commercial waterproofing job ACM completed in Suffolk County, NY. Owner Mark McAlpin walks through why a surface trench drain was the right solution for this property and when this type of system makes sense for other Long Island buildings.

In high water table areas like Long Island’s south shore, water often does not just come from below the foundation. It can pool on the surface, run toward the building, and overwhelm traditional drainage. A surface trench drain captures that water before it reaches the foundation and channels it safely away. For some properties, especially those with hardscaping or commercial layouts, it is the most effective solution available.

If your property has surface water issues, ACM can assess whether a trench drain or another drainage solution is the right fit. Schedule a free inspection today.
