Drain Rock
Drain rock aggregate is a clean, angular stone commonly produced in a 2" ISPWC size. Its open, free-draining structure allows water to flow easily through the rock, making it ideal for seepage systems, French drains, drainage trenches, and other applications where efficient water movement and filtration are required.
Common Sizes
2" ISPWC
Drain rock is commonly produced in a 2" ISPWC size, offering uniform stone that creates consistent void space for effective water flow. Its larger gradation makes it ideal for seepage applications, drainage trenches, and situations where controlled water movement is essential.
Common Applications
Foundation Drainage Systems
Allows water to move freely away from foundations to prevent hydrostatic pressure.
Retaining Wall Backfill
Improves drainage behind retaining walls and reduces soil expansion pressure.
Road & Highway Subdrains
Redirects groundwater away from road bases to maintain structural integrity.
Stormwater Management
Promotes infiltration and flow control for stormwater systems and swales.
Erosion Control
Stabilizes slopes, banks, and drainage areas to reduce erosion and washout.
Landscaping Projects
Creates clean, free-draining base layers for hardscapes, beds, and site grading.
