Basement & Cellar Drainage Channels
Clever Shield supplies high-performance basement and cellar drainage channels designed to manage groundwater and control moisture in below-ground spaces. When installed alongside Type C cavity drain membranes, drainage channels collect water at the wall-floor junction and direct it safely to a discharge point, helping protect basements from damp, water build-up, and long-term structural damage.
How Basement Drainage Channels Work
- Perimeter installation – Fitted along the wall-floor junction to capture water behind the membrane system.
- Water collection & discharge – Channels guide water to a sump pump system or gravity-fed drainage where applicable.
- Integration with cavity drain membranes – Works in conjunction with wall and floor membranes to reduce hydrostatic pressure and prevent moisture build-up.
Types of Drainage Channels
-
Standard perimeter channels
Modular, easy-to-connect channel systems with optional inspection/jetting access for maintenance. -
Slotted drainage channels
Designed for direct water entry, ideal for higher-risk zones, door thresholds and areas prone to increased ingress. -
Channels with integral upstands
Designed to sit flush to wall membranes for improved collection and continuity at the wall-floor detail. -
High-capacity drainage channels
Suitable for higher water volumes and sites with greater groundwater pressure, typically specified with robust pump systems.
Installation Benefits
- Built in from the start – Installed early in the waterproofing process for continuous water management.
- Neat, concealed finish – Typically installed within screeds or behind finishing layers for a clean result.
- Uninterrupted flow – Helps prevent water build-up behind membranes and reduces hydrostatic pressure on the structure.
Why Use Drainage Channels in Basement Waterproofing?
- Directs water away – Reduces damp risk by controlling water at the perimeter
- Protects foundations – Minimises hydrostatic pressure and water-induced stress
- Completes Type C systems – Essential for reliable cavity drain membrane waterproofing
Quick FAQs
Do I need drainage channels with a Type C cavity drain system?
In most Type C installations, yes. Drainage channels collect water from behind wall and floor membranes and direct it to a discharge point, typically a sump pump system. This is a key part of effective water management.
Where are drainage channels installed?
Channels are normally installed at the wall-floor junction (perimeter) and may include inspection/jetting access points for maintenance. The final position depends on the system design and intended floor build-up.
Do drainage channels require maintenance?
Like all drainage systems, periodic inspection is recommended. Many channel systems use inspection ports and jetting eyes to help keep the system clear and working as intended.
