SE keeps striding to develop innovative
soil & foundation technology
We’re living in the era of speed. The speed of environmental change and technology
innovation is remarkable. When everything changes constantly, we need to pay more
attention to core values of our society such as dignity of human rights, improving quality
of life, love and trust of family, friendship, healthy society, and environment preservation.
Core values in construction world are very clear: Cost reduction, improving construction
quality, shortening project period, and improving productivities. At SE, we believe these
values are shaping the business objective and defining the character of our company.
SE is an expert soil and foundation technology company specialized in design and
consulting for all types of ground condition for buildings and structures. Since we
developed cost effective Ext Pile in 2004, our R&D team has committed itself to develop
state of the art pile technology and foundation design methods which guarantee cost
savings and shorten construction period. SE’s innovative technology and engineering
capability, together with the consulting services leveraging extensive field experience of
various soil conditions, allow us to provide our clients with top-notched VE techniques
which contribute to reduce project costs and give a positive impact on construction
schedules.
We believe that development and environment protection are two sides of the same coin.
As constructions engineer, we change the world by enhancing challenging
environmental conditions, and as a global citizen, we always try to minimize the potential
impact that our ground/soil technology could have on the environment.
At SE, we believe that R&D is the most important to distinguish ourselves in this industry.
Our never-ending efforts in R&D were rewarded by awards from Korea government and
compliments from major construction companies. We’re proud that we already
registered over 100 intellectual properties, including patents and utility models, in Korea
and other countries.
SE manages to keep one step ahead of our revolutionary technology by constantly
predicting future construction industry needs. We believe only the best quality solutions
and service will guarantee our success. With the best in breed technology, we would like

SE‘s construction methods, such as Ext Pile, SAP, PF, GCB/Bindearth, are realizing the concept of ‘The less
the better.’ Our R&D team put priority on reducing the number of piles, the size of pile diameter and equipment, and construction noise. Also we try to shorten project time and cut total construction cost. In the
meantime, by deploying our methods into construction site, our clients could enjoy maximized productivity,
enhanced durability and eco-friendly construction delivery. Never ceasing in the research and development
of new technology, SE reinforces leadership in the areas of geotechnical engineering. We’re growing with
our clients as a trusted partner by adding value to every project we involve.
n
Visio
As a company based in Korea, a relatively small country, we could equip ourselves by dealing with tough
ground and construction conditions. By taking up challenges with enthusiasm, we could accomplish more
than what we can imagine. Our efforts converged into revolutionary solutions. We provide a comprehensive
range of geotechnical engineering solutions: easy & fast foundation methods for soft soil, jobsite with

This length equals to reaching the summit of Mt. Everest around 1,000 times,
and it’s longer than earth’s radius.
* Cost reduction and shortening project time are key drivers for construction company’s success.
Ext Pile reduces the number of pile over 30% comparing to legacy pile solutions.
Reduced number of piles directly affects to cost reduction, project schedule shortening and eco-friendly construction.
Moreover this pile system gets the positive feedback with increased construction feasibility and durability.

One tree absorbs 3kg of CO2 according to the environment reports.
We reduced 430,000 tons of CO2 emission in our construction projects over 10 years,
equivalent to the effect of 150,000 trees being planted.
This is accomplished by SE’s innovative construction methods designed
to reduce number of piles necessary for construction and shorten project time.
Project could be done with smaller equipment.
All of these elements are affecting to not only cost saving
but also keep earth green.
Over 10 years, SE devoted to reduce 430,000 tons of CO2,
same effect to plant around 150,000 trees
There is ongoing global concern of reducing greenhouse gas emission such as CO2.
Eco-friendly management is not only our responsibility as a global citizen
but also the key drivers for sustainable growth.
As an expert in soil improvement and foundation engineering technology,
we feel proud that every single step of our technology innovation and improvement in construction
method contributed to minimize environmental impact.
For us, eco-friendly technology means construction completion with less material
and smaller equipment within relatively short time.
At SE, we strive for developing new and more effective solutions for “greener” construction support.

The PF construction method is for medium/high-rise structures in soft soil.
With this foundation method,stable bearing capacity is secured.

Application Area
Concept of PF Method
PF (Point Foundation) construction method is
applied to soft soil which has risks of
settlement liquefaction. By substitution
of soft soil, allowable bearing capacity of
ground is attained (PF-S method).
With our specialized design stirring
equipment, bearing capacity is secured
by cone part in upper layer, as well as
settlement control by tail part in lower layer
(PF-M, PF-D)

Application for global site
Bindearth is an eco-friendly high-solidifying admixture. It shows excellent solidification performance for soft soil improvement,
point foundation, soil cement wall, and surface layer solidification.
Two types of products are available: BD5000 is additive type product for remote customer. It specially designed to reduce
distribution cost. BD6000 is provided in mixture type for local customers. Bindearth received Green Mark from Ministry of
Environment in Korea, and meets waste processing test standard.

Construction Method Characteristics
About GCB (Geo Ceramic Binder)
GCB is the structure repair, maintenance and waterproof technology to form long lasting unified structure. By utilizing slurry state of
Geo Ceramic Binder (GCB + water) with geosynthetic mat or form, it is possible to leverage mechanical characteristics and strengths
of geosynthetics - flexibility, and wide range of specific surface area.
• Large specific surface area and superior adhesiveness between old and new structures
• High strength, wear resistance and shock resistance
• High workability and superior eco-friendly method
• Wide range of application
• Significantly reduce man-hour and equipment
• Excellent for structure repairing and reinforcing for public works,
buildings, industrial plants and environmental facilities
• No need to dry out the surface.
• Excellent waterproofing capabilities of coating
