Traditional methods


· Wooden post foundations can only be used for lightweight structures, that is buildings made of timber, bamboo and/or other vegetable material.

· The main drawback of using timber for foundations is the risk of weakening due to attack by insects (mainly termites and beetles), fungus and rodents. Hence, protective measures are necessary. (See sections on Timber and PROTECTIVE MEASURES.)

· Timber posts can be driven into the ground, if the climate is predominantly dry, the site is well drained and destructive biological agents (mainly termites) are not common in the area. Further information: Bibl. 14.18, 14.22, 20.04, 20.05.
