Ice constructed by pumping water directly on the surface of a bare ice sheet to build ice on the top of the ice sheet. Uniformity and quality depend on construction practices. If ice is constructed using sound construction practices, then this ice, once completely frozen and inspected, can be considered as having similar strength to natural ice.
Walk around the ice carefully. To test the integrity of the ice, chip at it to determine the safety and density. If the ice comes off in chunks, it denotes that this is a high-density area - the ice is strong and should be safe.

The location is selected close to shore, but over a depth of water which will exceed the maximum ice thickness. Many factors affect ice thickness including: type of water, location, the time of year and other environmental factors such as: Water depth and size of body of water. Currents, tides and other moving water. Chemicals including salt. Fluctuations in water levels. Logs, rocks and docks absorbing heat from the sun.
