Really tall engineered walls

Discussion in 'Hardscaping' started by ChrisCoope, Apr 17, 2007.

  1. Thought I would share this (hopefully it posted picture) of a structural specially treated timber crib wall.
    It was quite a challenge, especially as the client reduced the working width to 2 inches wider than a bobcat530 !!
    The height of the stacked wall is just shy of 27ft ! - there are actually two walls stacked together to enable this height, the wall is not technically "structural" as it is infront of a rock face - it would need to have been about 14ft thick as apposed to its actual depth of around 8ft deep,to be fully structural. I'm not sure how these walls compare to the concrete alternatives in respect of construction times, but a relatively straightforward one usually can be built at a rate of about 300sq ft a day with a crew of three.

  3. You can see many more at www.wallsandsoundbarriers.com
    This first picture is of a 15 year old wall, that required some alterations, you may be interested to know that there was not one piece of wood that we found (over 20 tons was sent to the dump) that had any sign of rotting, we did find a piece that had been chewed by a squirrel !! The reason for zero rot is that all wood is treated to 98% not 40 or 60% that you can buy commonly.


    Here's another we stepped back the wall at this stage.
