Incorporate the base of the t brace by nailing it flush in between two posts in a course of the wall.
Retaining wall between fence posts.
Our fence post in system is engineered for segmental retaining walls srw utilizing the large hollow cores of the wall blocks to install either steel or wood fence posts.
H5 treated 200mm diameter posts one every 1 2m of wall length.
These joiner posts are suitable for retaining walls up to 1000mm high.

When building a tiered set of retaining walls position the higher wall behind the lower wall at twice the distance as the height of the lower wall.
Free draining metal backfill approximately 1 3m3will be used for every metre of the retaining wall length.
Installed behind the block.
This configuration applies minimal overturning forces to the back of the wall.
They are only 1 3 the thickness of conventional retaining walls.
For example if the lower wall is three feet.
Create retaining walls the easy way using a combination of end joiner and corner posts.
150 x 50mm or 200 x 50mm h4 treated rough sawn or tongue groove rails.
The design can utilize the resistance from the soil mass between the wall and post footing to reduce the forces from the fence.
I wouldn t recommend attaching the retaining wall boards directly to the existing posts as you can t assume that the footings are sufficient to handle the additional pressure and a separate wall makes it easier to fix repair replace the wood fence when needed.
Add t braces to the wall while being constructed for support.
Dig a t shaped trench behind the wall.
Placing the fence or railing a minimum of 3 feet 0 9 m or further behind the wall is the preferred lo cation.
Take a 8ft fence post dig a post hole 2ft next to retaining wall and butt the fence post against the retaining wall meaning the post will be in contact with retaining wall up to 2ft and pore concrete to fix the fence post next to wall.
The cantilevered post in unit combined with a concrete slab and the soil behind the wall will resist the overturning pressure of lateral loads.
Alternatively use 150mm half round trimmed rails.
