Specifications of TUPRO
Design TUPRO
TUPRO (TUrap PROgresif) is a retaining wall constructed with a stone arrangement and branching concrete blocks as binders.
Three construction points include:
- Branching concrete block design.
- Interlocking concrete block arrangement.
- The main material used is natural stone (andesite type) arranged using the Japanese "Ishizumi Method," which creates a stable structure that is not easily dislodged.
Main Material Using Natural Stone
With the majority of the material being stone, it is not only environmentally friendly but also strong. In addition to being sturdy and robust, it is also good for the environment as it can create new habitats for animals and other plants. The arranged stones have gaps and pores that will distribute groundwater, thus maintaining the balance of active and passive pressure.
Application of TUPRO
TUPRO is applied with a slope installation of 1:0.3 to 1:0.5
(1) Riverbank, River Cliff
(3) Hills, Mountain Slopes, Slopes on the Motorway
(2) Dam Cliff
(4) Fill Soil
Comparison of TUPRO with Other Methods
Besides Tupro, other methods generally use concrete. Its strength depends on how large, how deep, and how much cost is incurred.
This method will hold up well if the following conditions are met.
1. THERE IS NO CHANGE in the shape and position of the pile.
2. THERE IS NO CHANGE in pressure/load from above, the sides and the back.
If one of them changes due to rain and other factors, it may become damaged because it is not flexible enough to adapt to those changes..
→ However, in certain conditions, we may still use this method.
Comparison of TUPRO with Other Methods
Limitations of TUPRO
Ideal conditions for TUPRO installation
- Comparison of angles level 1:0.3 ~ 0.5 (range 60 to 70 degrees).
- The ideal installation height of Tupro is from 2 metres to 8 metres; if it exceeds 8 metres, terracing should be used.
- TUPRO can be applied to various types of soil including expansive soil, but the soil bearing capacity needs to be considered.
- If the load-bearing analysis indicates that there is a need for soil improvement and/or structural reinforcement using minipiles and similar methods.

Installation of TUPRO in Japan
Before Installation
After Installation (February 2003)
After 6 Years (2009)
After the heavy flood in July 2009, TUPRO was not damaged at all. Landslides occurred in other areas where TUPRO was not installed.
Now it remains strong even covered by naturally growing green plants.
Application of TUPRO in Japan
Used in many places that are prone to landslides, such as riverbanks and cliffs.
