Tents cannot be anchored with ground stakes on paved, tarred, or concrete surfaces. Water-fillable ballast tubes are the tried-and-true alternative: They are filled with water, placed on the dirt strips of scaffolding tents, or attached to the guy ropes, and reliably secure the tent on any solid surface. Ballast tubes are custom-manufactured by INHAG and are available in four standard lengths, as well as in custom lengths and colors upon request.
