Une barrière destinée à servir principalement de barrage de limon comprend un corps tubulaire avec une jupe plane s'étendant vers l'extérieur d'un côté pour ancrer la barrière au sol. Un ressort hélicoïdal dans le corps sollicite ce corps pour qu'il prenne une position d'utilisation sortie allongée. Ce corps peut être rentré et maintenu à l'état compact pour ranger ou transporter la barrière au moyen de courroies, aux extrémités du corps tubulaire, et de boucles qui s'engagent mutuellement de manière libérable sur les courroies.
