As opposed to precast, site cast, sometimes known as in-situ concrete, is poured, molded and cured on site Like precast concrete, on site concrete is formed in a mold and then lifted in place However, one of its advantages over precast slabs is that it does not need to be moved far to be lifted into place
For augered piles, the hole is excavated by rotary action of an earth boring machine until suitable founding material has been reached The depth capacity of available auger machines under unlimited headroom conditions is in excess of 50m in penetrable soil This depth may be extended with percussion drilling techniqu Obstructions may present a problem, and if any handwork ,
