Timber piles

Timber piles are the oldest of all the contemporarily used piles. They are usually precast displacement piles installed with the driving method, or less commonly, the vibratory method. The natural convergence of pile shafts allows to obtain a relatively high pile load capacity. Properly applied, they are a highly economical, efficient and safe foundation solution, both for temporary and permanent structures. This can be justified by a number of historical buildings founded on timber piles that have been in operation for thousands of years. Timber piles applied for the purposes of permanent structures are pressure-impregnated. The impregnation method is designed according to a specific foundation, soil parameters and water type (fresh or sea). Among the major advantages of timber piles are: (1) low material costs, (2) durability >100 years with reinforced concrete top plate, (3) natural convergence of pile shaft that enhances shaft resistance, (4) installation with minimal spacing, (5) minimal spacing allowing for the optimization of expensive top plates, (6) resistance to chlorides, (7) resistance to stray currents, (8) no need for anti-corrosion protection, (9) easy for road and railway transport and handling on the construction site, (10) installation with a standard pile driver, (11) can be cut off with just a chain saw, (12) in permanent structures they are pressure-impregnated with protection agents permitted for use in the construction sector, and (13) they are environment-friendly as being made a natural renewable material (wood).
