Can ECCOfence gabion baskets be installed on stabilised sand or screed (150 g cement/m³)?

No, because ECCOfence gabion baskets are anchored with 12 mm diamter expansion bolts. Expansion bolts exert such an amount of force (allowing the gabion basket to be solidly anchored) that stabilised sand or screed would break. Gabion baskets must always be anchored in concrete (at least 350 kg cement/m³).
