Nanoalps® System SAFE is an environmentally-friendly, non-toxic polymer additive which creates water-impermeable layers, seals and also rehabilitates contaminated grounds. It is used with clay mineral binding agents as well as reduced grain-size minerals and recycled raw materials.

The properties of System SAFE
- Nanoalps® System SAFE – perfect for waterproofing landfill sites
The Nanoalps® System SAFE can form an impermeable layer which is much thinner than traditional clay waterproofing but equally as efficient. This ensures excellent savings in terms of both the cost and the transportation of raw materials.
-
Properties overview
- Improved elasticity and high levels of waterproofing
- Minimisation of dry-splitting through a reduction in the swellability
- High level of chemical and biological stability
- Good processability
- Cost-savings through a reduction in the required layer depth
Application areas
Application areas of System SAFE
Nanoalps® System SAFE can be used in all areas where a high level of impermeability and waterproofing is required, e.g.:
- Landfill sites
- River and sea dykes
- Dams and embankments
- Water reservoirs and water-storage facilities
- Near to rivers and protected water and nature areas
Technology
-
Improved material stability
Load-tests show an improvement in material stability.
- Without Nanoalps® System SAFE
Without the use of the polymer the material remains brittle and long tears appear.
- With Nanoalps® System SAFE
With Nanoalps® System SAFE the load is spread out more evenly, so that the wearing-down of material is minimised.

- Build-up with Nanoalps® System SAFE
Through the use of Nanoalps® System SAFE a higher level of impermeability is achieved and the depth of the mineral layer can be reduced to a large extent.
- Recultivation layer
- Geomembrane 400 g/m²
- 30 cm drainage layer
- PEHD foil 1,000 g/m²
- 20 cm mineral layer using Nanoalps® System SAFE
- 20-40 cm gasdrainage and compensation level
-
- Build-up without Nanoalps® System SAFE
Without the sealing characteristics of the polymer additive the layer would otherwise have to be drastically increased and this results in a lower level of chemical stability.

- Geomembrane 400 g/m²
- 30 cm drainage layer
- PEHD foil 1,000 g/m²
- 100 cm mineral layer
- 20-40 cm gasdrainage and compensation level
