Denver System®
The technology for this method was introduced from
Denver Grouting Services, Inc. in the U.S.A. An
extremely low fluidity soil mortar having a very low slump
value is injected into the ground to form a uniformly

precisely within the planned region without straying to
provide homogeneous grout bulbs.
2. The injected grout has a compacting effect on
the surrounding ground, thus achieves ground
improvement and increases earthquake resistance.
3. Ground improvement can be carried out on basement
structures or in the confined spaces without
displacement of the existing structure.

High hydrostatic pressure-resistant Anchor Method
In recent years, along with the increase in the scale and depth of excavation with
shoring, the ground anchorage work under high hydrostatic pressure has been
required.
In anchoring work under high hydrostatic pressure, the treatment of underground
water is very important and the main tasks are to control the outflow of underground
water or sediment and to prevent displacement or collapse of the ground during
construction.
The high hydrostatic pressure-resistant Anchor Method utilizes special equipments
such as the water-stop box and the grouting packer, etc. solves the problems of
anchoring work subject to high water pressure. This method contributes to install the
successful ground anchor under such condition.

Compacting Work
BSP Dynamic Compaction
This is a new method of compaction that makes use of
technology developed by BSP International Foundation
Ltd. in the U.K. A device with a special circular foot
that is in contact with the ground is used, and a weight
is allowed to drop repeatedly to compact the ground.
Effective compaction is possible to a depth of several
meters by use of an impact frequency of 40-60 times a
minute.
Features:
1. The method can be used for the compaction of a wide
variety of materials and/or ground conditions such as soil,
rock masses, and waste products.
2. The use of the special foot enables the method to be used
in cases where there are angular and projecting rocks
or foreign material inclusions. Therefore, the method is
ideally suited to the compaction of waste products.
3. As the special foot stays in contact with the ground, there
is no danger of flying debris, making the method safe.

2. Through efficient mixing by DJM method, the pollution by
VOCs can be remediated.
3. As processing can be conducted by non-excavation, the
shoring work is not necessary and the spread of pollution by
excavating can be prevented.
The reduced iron powder which is useful to decompose
VOCs chemically can be mixed in the polluted ground by
DJM method. As the specified quantities can be mixed
uniformly, it is possible to fully purify the polluted soil.
Further, through underground construction of a permeable
remediation wall, it becomes possible to purify polluted
groundwater.
