Cavity Drain Systems generally require a collection sump + pump to manage the collection and discharge of ground and/or foul water. This automatically manages the evacuation of water ingress and requires mains power to operate.

High level water alarm and monitoring system which will alert a home owner when there is a potential fault or service required to the sump pump.

Battery back-ups will keep the sump pump working in the event of power failure.

The number of pump systems required for each project will depend on the overall basement size, perimeter and also the method of drainage – Delta Channel, Modular or combination of the both.

Drainage Options

Drainage options for a Delta Type C Drained Protection System include Delta Channel, Modular Drainage System or a combination of both. The Delta Drainage Channel as with the Modular Drainage System should ideally be recessed within the structural slab. Where this is not possible or practical, then a sacrificial screed bonded to the structural slab should be used to form a rebate for the perimeter Delta channel.

Channels incorporated into the design and laid level allow water to drain by hydraulic gradient and can discharge passively any water ingress into a Delta Sump or other suitable discharge point. Maintainance issues need to be considered. (BS 8102:2009 Section 10.3.1).
