    Description
    The 3" Weep Hole Filter prevents soil loss, erosion, and hydrostatic pressure buildup behind seawalls by allowing controlled water drainage through the structure.

    Engineered for durability in harsh marine environments, this filter ensures long-term performance and reduces maintenance needs. Its replaceable filter media effectively captures fines and sediments while still promoting proper water flow. Easy to install and designed to fit standard 3-inch weep holes, it’s a reliable solution for extending the lifespan of seawalls, retaining walls, and waterfront structures.
