Coordinating Drainage Sheets Below Landscaped Areas
Drainage sheets below landscaped areas need coordination with the planting build-up and waterproofing protection. Sheet selection should be connected to the complete detail rather than judged from the dimple pattern alone.
Selection considerations
Review the proposed layers, drainage route and interfaces with planters, edges and outlets. Identify which component provides drainage, protection or filtration in the approved design. Do not assume every backing or sheet in a product family performs all of these functions.
Ask the supplier to confirm the selected product's documented application and installation arrangement. Coordinate it with the waterproofing and landscape teams before covering the area. Keep loading, drainage and compatibility requirements in the project brief instead of deriving them from a generic product name.
Inspect the layers and outlet interfaces at the agreed stage. Record locations and any subsequent penetrations or repairs. Provide the operator with the as-built drainage route so later landscape changes can be reviewed without guessing where water is intended to flow.
Before you specify or order
- Identify each layer's intended function
- Coordinate drainage routes and outlets
- Confirm the selected application
- Retain as-built interface records

Common question
Does a dimpled sheet automatically provide the full drainage design?
No. Its role, backing, outlets and surrounding build-up must suit the approved landscape and waterproofing arrangement.
