To waterproof the roof of a pumping station, a multi-layered system is typically implemented:
Screed Layer: A uniform layer of screed is applied over the structural concrete roof. This screed can be of consistent thickness or strategically varied to create a slope for efficient drainage. The primary functions of the screed are to provide a smooth surface for the subsequent waterproofing membrane application, enhance adhesion between the membrane and substrate, and contribute to thermal insulation.
Waterproofing Membrane: A specialized waterproofing membrane is installed over the screed. This layer is the primary barrier against water intrusion, ensuring the roof remains watertight and protecting the pumping station’s interior from leaks and moisture damage.
Optional Insulation Board: Depending on the climate and the specific requirements of the pumping station, an insulation board may be placed on top of the waterproofing membrane. In cold weather conditions, this board reduces heat loss through the roof, maintaining a stable internal temperature. Conversely, in hot weather, it mitigates the temperature rise caused by direct sunlight, preventing the pumping station from overheating.
This comprehensive waterproofing system ensures the pumping station’s structural integrity and operational efficiency by protecting it from water damage and maintaining a comfortable internal environment regardless of external weather conditions.
