A look at the 4 types of interlock with segmental retaining wall systems.
In segmental retaining wall construction, there are 4 types of interlock:
- Shear strength
- Independent or dependent mechanical device
- Void fill
Here are additional details for each of them.
This is the block to block contact.
Using denser blocks makes a wall stronger.
The strength comes from each block sitting on top of each other.
Independent or dependent mechanical device
Techo-Bloc created clips and pins that come with its wall systems, which are independent mechanical devices.
They can be used for better alignment by sliding them into the back setting of the wall unit.
They provide the desired setback and tie these units together.
Void fill interlock is obtained using ¾-inch angular stone.
This type of stone is less than 5% passing the 200 sieve.
They can be added behind the wall and into the cores of the units.
As an aggregate is woven through the units, it ties them together even more.
The last type of interlock is pattern.
It is obtained by not lining up the bonds of the blocks while building the wall.
