Foundations for buildings, constructions or utilities are often made of poured concrete , usually reinforced with steel.

  • The production of the cement used in concrete uses a great deal of energy
  • Considerable earth removal and preparation of concrete is normally required
  • When no longer required the foundation cannot be easily removed or resued

Screw piers

  • Screw piles doesnot require earth works – they are screwed into the land
  • Screw piers can be refused if the site is only temporary
  • Steel screw piers don’t rust – ¬†they are protected from the elements under the soil and any exposed part should be suitably coated to prevent rusting
