Ballast Tubes

Ballast tubes are used in conjunction with liner in order to keep liner from uplift due to ground water, gas, or wind. Ballasting is often required for steep slopes where large portions of a slope are exposed to the wind and elements, which can create unwanted uplift of the a liner system. They are also frequently used when ponds, pits, or reservoirs remain empty for long periods of time.
