Water Weights proof load bags

Water Weights water filled proof load bags are a unique and simple product specifically designed to provide a test load instead of traditional solid weights for all forms of testing.

The development of Water Weights bags has increased greatly the practicality, economy and safety of providing proof load testing in many applications. In addition, certain proof load testing situations only become feasible with the use of Water Weights.

Safe
Water Weights water bags are certified in accordance with Health and Safety Executive requirements. The bags have a physically proven factor of safety in excess of 6:1 and are proof load tested to over 2:1 prior to being taken into service.
When performing load tests, gradual application of the load allows problems to be quickly identified prior to attaining maximum load.

Economical
Water Weights bags weigh less than 2% of achievable load allowing for considerable savings in transport, storage and labour costs.

Flexible
A wide range of different sizes of Water Weights bags is available. Bags can be hung in combinations to achieve large loads. Specialist ?low headroom? bags are available for testing where headroom is restricted. With bags weighing only some 2% of achievable load, floor-loading restrictions are rarely a problem. Bags are ideally suited to inaccessible lifting points. A variety of add-on options are available to meet specialist requirements such as extended drainage trunks, drain valves and manifold control systems.

Simple
Water Weights bags are very light, so aiding handling. Bags are fully rigged and ready to hang and fill. Controlled filling and emptying is simple. The load is measured accurately with a certified loadcell or flowmeter. Overall bags are simple to use.
The Water Weights extensive range of equipment is available for hire.
