Perpendicular height explained

Most pool owners are aware that their pool barrier must measure 1200mm but there are other considerations that we’d like to explain:

• Perpendicular Height

When you have a barrier traversing a change in ground level, attention must be paid to the height of the barrier panel when measured from the base of the panel at the upper level, across to the top of the panel at the lower level. Ideally a custom panel that is mounted at both upper and lower level would resolve this, however here is a fix that resolves perpendicular height. Previously the perpendicular height was 700mm but with the addition of a timber infill, the minimum measurement of 900mm has been achieved. Remember your infill must be secured in place so as to be rigid and should be the same width as the pool barrier, so that there is no ledge that measures in excess of 10mm.

• Finished Ground Level

Barrier height is measured from any permanent surface that is located within 500mm of the pool barrier. If you have garden edging, rocks, steps or other surfaces that are in this zone, your barrier height could be reduced to less than 1200mm is their presence has not been taken into account when constructing the pool barrier. To resolve this issue it is a case of either removing the object (possibly not your preference) or increasing pool barrier height
