Corten steel requires no maintenance, as over time it develops a crystalline rust patina that dramatically reduces further corrosion

Posts set in concrete pile holes

Generally the retaining wall pile hole depth is equal to the height of the retaining wall. However in softer soils or walls supporting sloping ground, driveways, or buildings, the post and pile retaining wall method solves this by adjusting the post spacings and pile depths.

Corten Steel Care and Maintenance

Corten steel, also known as weathering steel, is a high tensile steel that forms a protective layer of rust or patina when exposed to the elements. This patina shields the steel from further corrosion, giving it a characteristic reddish-brown color.

To form this protective patina, corten steel needs repeated cycles of wetting and drying. If buried or otherwise prevented from experiencing these cycles, corten steel will not develop the patina and will rust at a similar rate to mild steel.

To extend the lifespan of corten steel, ensure all retaining walls have adequate drainage to prevent hydrostatic pressure buildup. Poorly drained retaining walls with saturated soils will shorten the lifespan of unprotected corten steel.

For this reason, it is recommended sealing the insides of planters and the backs of retaining walls made of corten steel with a bitumen sealer.

Thin (1.0mm to 1.5mm thick) unprotected steel when buried has quite a short lifespan

By following these simple care and maintenance tips, you can ensure that your corten steel structures will last for many years to come.
