UNPROTECTED DRAPERY SYSTEMS CAPTURE DEBRIS AND SWELL-OUT
Drapery systems may retain falling boulders, but result
useless against the erosion of the finest materials whose
continual removal by rain, wind, snow and freezing-thawing,
degrades the supporting base of larger dimensions stones
that detach and fall downstream swelling out the net.
The material accumulated in swollen nets must be therefore
periodically removed and the net re-positioned, with high
risks and maintenance costs.
Sometimes the drapery systems get damaged by the
operation and must be replaced.

Formation of pockets of eroded material,
deformation and detachment of drapery systems
DRAPERY SYSTEMS + PRATI ARMATI®
= STOPS EROSION = PROTECTED NET
PRATI ARMATI® sown over drapery systems allows to block
the erosion of finest materials and thus the detachment of
larger rocks, saving important maintenance costs.
Thin and homogeneous roots avoid bulges in the underlying
soil layers of whatsoever origin, even in fractured rocks.
PRATI ARMATI® grows without irrigation and maintenance,
even on most sterile lithotypes and in arid climates.

The thick aboveground green layer, beyond visually masking
the drapery systems, also decreases the infiltration of water
and protects the underlying soil from excessive thermal
shock.
