When high-water tables are present, anti-flotation methods need to be considered. The Devan StormVAULT anchor system makes this easy with the smart design features.
Features
- Devan’s innovative ribbed and conical StormVAULT compression disk keeps positive tension on the restraint ropes to reduce the possibility of upward movement.
- The unique conical and circular design has superior soil interaction and the ribs locks the compression disc in to place with increased cross sectional area preventing lateral sliding under tension.
- Devan’s industry leading innovative StormVAULT 316 stainless steel redundancy bracket ensures both portions of the anchor set act independently.
- 316 stainless steel fittings ensure the critical components do not fail over the life span of the tank.
The number of anchor kits is depended on ground cover and the water table, our easy-to-use chart can guide your selection.
Each kit contains 2x stormVAULT compression disk, 1x stormVAULT 316 stainless steel redundancy bracket, 2x Nylon ropes and the required 316 stainless steel fittings.
