basic information
Purpose of Using Weep Holes Products used to prevent cracks in structures and uneven settlement or uplift caused by uplift pressure and scouring effects from infiltrating water or seepage flow. Excessive groundwater pressure pushes the rubber valve upward, releasing water into the drainage channel and preventing cracks and uplift in the structure. When the water level in the drainage channel is high, the water pressure causes the rubber valve to close, preventing leakage of irrigation water and scouring effects. *For more details, please refer to the PDF document or feel free to contact us.*
