Fields of application
In roof areas used for traffic, Delta - Terraxx assumes the function of a
protection, filtration and seepage layer. Laid onto the waterproofing,
this structural drainage layer ensures that any precipitation or water
potentially percolating into the structure is drained away without
delay. It may be directly covered with a layer of sand or stone chips
which may in turn may be topped with a walkable pavement of
stones or flags for both light and heavy loads.
- Walkable roofs
- Car park decks
- Paved terraces
- Basement and retaining walls in high water table areas
- Extensive green roofs where no additional water storage is
required
Features
- Extremely high compressive strength of 400 kN/m2
- High drainage capacity for garden roofs
- Self sealing edge allows for quick installation of an all-encapsulating protection layer
- Can be installed at depths of up to 10m, even in extremely wet conditions
- Integrates seamlessly with Derbigum Manufacturing (Pty) Ltd torch-on systems to provide lasting protection<
Installation
- The sealed surface must be thoroughly cleaned, so that after installation of the drainage layer no damage can occur to the waterproofing. The waterproofing must be root resistant or protected by a root barrier. A protective separating layer is laid on the waterproofing.
- The dimple sheeting is simply rolled out on the underlayer. Dimples facing the surface and cups facing up. The sheeting can be cut with a blade.
- To extend a sheet, lay two rows of dimples together.
- Install the sheets step by step

Drainage Lengths
Because of its disproportionately high drainage capacity,
Delta TERRAXX is suitable for great drainage lengths and, by the same token, for roofs with an unusually low gradient.
