Segmental Retaining Wall Block Vs Mortared Concrete

The walls are structurally stable yet they remain flexible to tolerate minor earth movement without damage.

Segmental retaining wall block vs mortared concrete.

In 1986 allan block introduced its first segmental retaining wall block srw. 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 individual units interlock with each other to avoid overturning and sliding. Without joints poured walls possess a greater lateral strength which essentially means they have a greater ability to resist pressure presented by water and the soil.

Segmental retaining walls can be designed as either conventional or as reinforced soil as illustrated in figure 1. The structural capacity of the srw system will vary with the srw unit size shape batter etc. The dry stack construction technique allows the incidental water to escape by flowing around the blocks and out the. Manufacturer s recommendations should be followed regarding the capacity of their particular system for the soil loads under consideration.

The hollow core design combines with mortarless construction to allow water to drain freely from behind the segmental retaining wall. Since 1987 versa lok has been creating solid solutions for architects and engineers with the industry s original solid top pinning segmental retaining wall system. Whether you choose concrete block stone or another material you ll want to understand the basics of retaining wall construction so that you can make sure your wall is designed and built correctly. Segmental retaining walls are constructed without mortar or concrete footings.

This method creates walls that are easy and economical to install. You ll need to consider the purpose of the wall the look your desire and your budget when deciding what retaining wall material is right for you. Water and weather wear down the mortar over time and can causes leaks. Incidental water moves easily through a vertical drain that is formed by the layer of wall rock placed behind the block and in the block cores.

Srws are modular blocks made from concrete that are often dry stacked without mortar. Our low absorption high strength solid concrete units provide not only the long lasting durability engineers expect but also the limitless number of design options. Segmental retaining walls srws are designed to be used as a gravity wall either with or without reinforcement and can have heights in excess of 40. 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.
