Precast concrete drainage headwalls are a critical component of any effective drainage system. Designed to connect pipe work discharging into open water courses, they help prevent erosion at discharge points into watercourses such as rivers, ditches, swales and attenuation ponds. By safeguarding pipes from erosion and water pressure damage, headwalls enhance the efficiency and longevity of your drainage infrastructure.
