Segmental retaining wall srw units typically have a smaller face area 1 square foot or less with a unit depth of less than 24inches most are 12 inchesin depth and are generally hand installed and dry cast by astm definition.
Segmental block retaining wall design.
Prior to the initiation of a project the owner should work with the srw design engineer to establish the scope of responsibilities and understand the limits of the srw design engineer s responsibilities segmental retaining walls are a relatively new earth retention system in north america which has led to the frequent use of design build relationships where the srw design engineer works for the srw installer this practice should be avoided to minimize potential.
Segmental retaining walls are generally installed with a small horizontal setback between units creating a wall batter into the retained soil ω in figure 2.
The wall batter compensates for any slight lateral movement of the srw face due to earth pressure and complements the aesthetic attributes of the srw system.
The walls are designed and constructed as either gravity retaining walls conventional or reinforced soil retaining walls.
Geotechnical engineers should be hired to evaluate the overall stability of the site.
These masonry blocks are significantly economical and effective for segmental retaining wall construction and it is also broadly accepted.
