How to: Permanent formwork for underwater construction joints

The use of Stremaform® underwater simplifies and minimises the submerged construction work. The formwork is simply placed on the substrate; elaborate support and anchorage is unnecessary. This simple installation of the substantial units reduces the overall cost of underwater work to a minimum.

How to:

  • Bring the underwater substrate to the desired height and level it.
  • Submerge and position L-shaped Stremaform® sections, fix into position with earth anchors and connect the units together.
  • Begin the concrete pour at the Stremaform® units in order to stabilise the formwork through the weight of the concrete.
  • The concrete is poured in layers up to the top edge of the formwork sections.
  • For greater component heights, additional Stremaform® formwork can be positioned once the concrete has hardened and the process repeated.
