CEO Message

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 to enjoy continous growth with our precious clients.

SE researches ground, the earth’s skin. We want to keep the skin beautifully by minimizing environmental impact and maximizing productivitySE is passionate to develop and improve construction technologies and methods which work beautifully with the ground, the earth’s skin.

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 limited access and building construction nearby railway facilities.

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 equip-ment, 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.

Construction cost saving reaches USD 300,000,000.Work time has been reduced around 30 years.SE’s extended end pile (Ext Pile) kills two birds with one stone by reducing construction costs and shortening project time.

This construction method has received positive feedback from engineers in many construction sites in Korea and global fields. With extended endpoint, bearing capacity is maximized. Meaning, you can complete piling work with reduced number of piles and expect same strength.

With this method, you can save not only pile cost, but also labor cost. Another benefit of deploying Ext Pile is shortening project time. In the last 10 years, Ext Pile contributed to reduce project time over 30 years in total.

SE feels proud that our technology innovation directly translated into our client’s benefit.

Over 10 years, SE devoted to reduce 430,000 tons of CO2,same effect to plant around 150,000 treesThere 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.

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.

• Construction of four-story research facilities in soft ground of coastal reclaimed land ⇒ Bearing capacity more than 150kN/m2 is secured

• Heavy equipment access was not possible because of the soft ground (<N5) and temporary facility interference ⇒ Bulb formation and surface-layer substitution applied

Mid-deep Processing Case

• Construction of 27 house building on fill-up ground of colluvium )40% of gravel and boulder mixture) ⇒ Bearing capacity more than150kN/m2 was the requirement

• In cas of piling, 35m SDA+T4 construction could be applied ⇒ Mid-layer processing and surface-layer substitution was actually applied

GCB

GCB is eco-friendly material ideal for repair/reinforcement of concrete structure and plant facilities.


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.
