Cover Soil Drainage
Well designed drainage is a key consideration in slope stability analysis. This video outlines the factors that need to be taken into account to ensure veneer slope stability with a sufficient factor of safety.
Pozidrain G is a product range designed to provide enhanced interface friction along with continuous drainage across the whole area.

Designing Stable Slopes – The design of slopes needs to take account of a number or parameters for construction and long term stability
Multi Layered Systems – A capping design may need to take into account gas venting, a barrier, surface water drainage and cover material
Slope Stability Design – Good drainage design is key to the stability of veneer slopes, and avoids the risks of saturation
Testing Requirements – The interfaces between layers and internal shear properties all affect the design
Standard Flow Capacity Test
This technical paper published by Ground Engineering investigates the importance of the in-plane flow capacity test for geocomposite drainage layers and the effect this has on slope stability. Click the image to download the paper.
