■Brief Greeting■From the start of company in 1997, we have developed and supplied unique and effective product lines tothe construction market, especially for slope stabilization, reinforcement of existing structures, tunneling,
and prestressed concrete works. Our products are forcusing into very narrow part of constructionengineering requirements which cannot be solved with conventional equipement. Recently, manyengineers talk about [Sustainability] of the facilities and those maintances. We would like to continue tosupply our services also to meet with our customers' goal in our best efforts, from design and engineering
aspects.

Micro Pile Systems【SP Soil Nail has granted as「Recommend to use Prize」from
the Ministry of Construct'n & Infrastructure & tourism！】

Micro pile systems are efficient for Seismic reinforcements, haltage ofDifferential Settlements, and to increase supporting capacity of various
exisinting structures. Can be installed with compact and conventional anchor
machines; therefore, can apply inside the existing building and/or very
narrow restricted space construction.

Prestressed Concrete

Various umbrella pipe-roofing and face bolt systems
can supply for NATM (New Austrian Tunneling
Method). We also offer tunnel void-filling with
Urethene foams for existing tunnnel restorations.

To extend structural life span against Choride attack and fatigue failure of Prestressing Strands, offering to
use Plastic duct for Internal tendons, and to improve grout cover for External tendons suggest to adopt spiral-ribbed Polyethylene pipe. Various component parts for Segment matching faces and connection points, grout
overflows, halt against water intrusions are provided.
