Re: Rockery Retaining Walls

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you don't mind the typical 1:4 face slope this can be analyzed as a
gravity wall.  If you require a vertical (or near) face then you will
probably tend to a concrete block or concrete face reinforced earth type.
It would appear that you need to be able to do it with minimum hardware so I
suggest designing with a face slope.  The site techniques will require a
good mason or rock wall builder since type of rock and/or face patterns may
determine style of assembly.  I have a simplified design analysis method if
there are no more readily available sophisticated ones at hand.  For block
or reinforced earth types you would be advised to consult a reputable
contractor/supplier who has the appropriate experience.
