Terraces are mostly constructed on stakes. Terrace foundation must be constructed below the freezing line of the soil, at least one meter in depth.
The earth below the terrace is best to be completely excavated of the soil in order to be filled with sand – this will help to avoid later plant growth below the terrace. Impregnated wood is used for terrace construction. Terrace flooring is either even or fluted. Fluted boards gather more rubbish in its flutes, but are visibly more pleasing. The board are fixed with hot-dip zinc countersunk-head nail or with special screws.
