A Class E Rated Cover for Heavy Duty Applications

The Nondo CE180 monitoring well cover is an all cast iron, ‘Class E’ rated well cover, designed for extra heavy duty applications. It is ideal for 50mm monitoring wells and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class D & Class E. The small 180mm OD makes it ideal for drillers who typically use a 200mm concrete corer. The CE180 has two new concepts for groundwater monitoring well covers:

  • A special shaped skirt to allow a wider concrete support lip and with a larger opening than comparable covers of similar diameter (116mm opening)
  • Bottom sealed bolt holes with removable grub screws for easy bolt hole cleaning if necessary. This ensures ultimate sealing from surface water ingress
