Catch Basins in Islandia, NY

Catch basins are essential drainage structures that collect surface water at strategic low points across your Long Island property, preventing flooding, erosion, and water damage to structures and landscaping. Brothers Paving & Masonry designs and installs catch basin systems tailored to the specific drainage challenges of Nassau and Suffolk County properties, from residential yards with standing water to commercial sites managing large volumes of stormwater runoff.

A catch basin is a below-grade collection box with a grated opening at the surface. Inside, a sump at the bottom traps sediment and debris before water exits through a connected outlet pipe to a dry well, storm drain, or other discharge point. This sediment-trapping function prevents debris from clogging downstream pipes and helps protect water quality in Long Island's sensitive coastal environment. Without adequate surface collection points, rainwater pools in low spots, floods against foundations, and creates soggy, unusable yard areas. Catch basins placed at these natural convergence points provide a direct pathway into the underground drainage system.

Our installation starts with a detailed site evaluation to observe water movement, identify accumulation points, and assess soil conditions and discharge options. We excavate to accommodate the basin body plus a gravel bed for stability, set the basin level with the grate at or slightly below the surrounding grade, and adjust the surrounding surface to funnel water in from all directions. Standard polyethylene basins serve most residential installations, while precast concrete basins handle larger residential and commercial applications. The outlet connects to solid PVC piping at a consistent downhill slope to the discharge point. For properties with severe drainage issues, we frequently combine catch basins with French drains, channel drains, and dry wells for a comprehensive layered solution.
