CDM BaseDrain & FloorDrain

  • Efficient Water Management: Designed to effectively collect and discharge water ingress within the Newton CDM System, preventing water accumulation and ensuring a dry basement environment.
  • Comprehensive Integration: Works seamlessly with CDM Fibran XPS-500C insulation boards, utilizing the 18mm holes for optimal water entry from beneath and within the spacer zone.
  • Enhanced Drainage Performance: The strategically placed holes on both sides and the top surface of the profiles facilitate efficient water flow into the drainage channels, improving overall system performance.
  • Reliable and Durable: As part of the Newton CDM System, CDM BaseDrain and FloorDrain are built to provide long-lasting and robust drainage solutions, ensuring consistent performance and protection against water ingress.
  • Supports Safe Water Discharge: Channels collected water to a Newton Basement Pumping System or safe drainage, providing a reliable solution for managing water ingress in below-ground structures.

Newton CDM BaseDrain and CDM FloorDrain is the drainage system used most commonly within the Newton CDM System – A range of products that collectively receive water ingressing at weaknesses within the structure and then discharge the collected water to a Newton Basement Pumping System or safe drainage.

The 18mm holes drilled in both sides of the profile, as well as to the top surface, allows water from beneath the CDM Fibran XPS-500C insulation boards and within the spacer zone to enter the drainage channels more easily.
