Foundation screws are perfectly suitable for installing in fresh water and sea water.

A distinction must be made here between two cases:

• The installation is carried out in shallow water: an installation machine that does not require a specific tool can be used. As the Toku MI4500 is pneumatic, there is no risk of electrocution.
• The installation is carried out in deeper water: the pneumatic machine must be adapted to the work carried out underwater.

The service life is measured in terms of years before any maintenance of the galvanization is required.

Obviously, this depends on the environment in which the screw is installed.

• In less aggressive environments, the service life is between 35 and 50 years.
• In marine environments, the service life is between 9 and 11 years.

As exotic wood with large cross-sections is rare and expensive, WeasyFix proposes a structural alternative enabling the use of small cross-sections of exotic wood while reducing the number of foundation screws required to ensure an even load distribution.
