Retaining Walls
Pisa II Retaining Wall
Pisa II is the most common wall stone that Unilock produces. It comes in a variaety of colours and can be used to build walls up to 3ft tall.
You can use this stone for taller walls with the use of geo-grid. It has to be used in walls taller then 3ft and it ties a minimum of 3ft into the grade behind the wall. By using this material you can increase the height of your walls without losing the structural intergrity of the wall.
Geo-grid can be used with all types of wallstone made by any manufacturer. I would not recommend building any walls taller then 3ft without it. Unless you are using a bigger stone that has been approved for taller applications.
The top picture is an example of a 3ft tall Neveda Pisa II retaining wall. The bottom picture is what the what the site looked like when we started. It was very common in the 1980's to use railroad ties for your walls. They were cheap and lasted a long time. However, now they are considered toxic waste and are very hard / expensive to dispose of!
