A Type C System is an internal groundwater management system. The system relies on a cavity between the external skin and internal finish of the structure; groundwater is guided to an appropriate sump and pump system or a suitable drainage outlet with a non-return valve.

Area of use:

• New Build Basements
• Any new Underground Structure
• Below Ground Structures
• Retaining Wall
• Existing Below Ground Structures
• Existing Basement Structures

What you should consider:

• Contaminated Water entering the system.

• Ensuring the external basement wall provides enough primary resistance to water ingress to ensure the cavity accepts only a controlled amount of water or dampness
