Review: Ho provato a bagnare questi sacchi e da gonfi arrivano ad uno spessore di circa 11 cm. Dentro il gel non è sciolto, ma in fogli che sembrano di panno e che hanno una forma - pur essendo un foglio unico - che permette al sacco di piegarsi un po', in modo da adattarsi abbastanza ad eventuali curve. Secondo me nelle zone dove ci sono gli angoli, è comunque impossibile che facciano tenuta totale, a meno che non si mettano più file di sacchi, una dietro l'altra, ma qualcosa di acqua può entrare. Ho provato anche a tagliare un sacco e dividerlo in tre parti per poterlo usare in zone più strette, ed ho ricucito il cartatessuto che lo avvolge e si può fare. Comunque sono soddisfatta dell'acquisto e ne ho comprati altri. Il rapporto qualità/prezzo è buono, il migliore che ho trovato sul mercato.
Review: Achat préventif à risque inondation. Produit conforme... malgré livraison carton semi ouvert au contenu tout de même vérifié avec livreur trés sérieux.

*by A***D on 12 July 2018*

Nicht tauglich. Funktioniert leider nicht wie es dargestellt wird. Die Säcke werden von starkem Wasser mitgespült. Sie halten nur geringem Wasserdruck stand. Diese Qualität gibt es zudem von anderen Herstellern deutlich günstiger, z.B. bei eBay. Wenn es darum geht, Sturzbäche oder stark fließendes Wasser abzuhalten, sind sie leider zu schwach. Schade, die Idee ist gut.
