Does the membrane remain perfectly tight?

To the eye, the membrane presents impeccable tension, with only a slight technical bend of about 1 cm per meter of width. This tension, combined with centrally located drain holes, prevents any water stagnation, thus limiting the accumulation of dirt. Leaves deposited on the membrane are easily swept away by the wind.

Over time, the membrane retains its perfect hold, the initial bend does not increase. In areas with extreme weather conditions, it is even more important to maintain a normal water level so that the water supports the membrane during heavy snowfall and preserves its aesthetics.
