[Asia Economy Reporter Chunhee Lee] Korea Land and Housing Corporation (LH) has succeeded in developing new construction technology through collaboration with private companies. This is the first achievement since its establishment in 2009.

On the 3rd, LH announced that the "High-Temperature Curing Method of Cement Grout Using Water Heating Heater in the Hollow Part of Pile for Early Confirmation of Bearing Capacity of Driven Piles," jointly developed with BTENC, Hyundai Engineering, and Sampyo P&C, has been designated as a new construction technology (No. 891) by the Ministry of Land, Infrastructure and Transport.

Driven piles are foundational structures used in most domestic construction and civil engineering projects such as public housing and bridges. They are installed by drilling holes into the ground, inserting piles, and filling the space between the pile and the hole with cement grout. To ensure that the installed driven piles safely support the structures, quality control to confirm proper curing (hardening) of the cement grout and bearing capacity is crucial.

However, previously, curing the cement grout took seven days, causing significant delays in confirming the pile's bearing capacity. The new technology jointly developed by LH utilizes the principle that cement grout hardens faster at higher temperatures. Water is filled into the hollow center of the pile and heated with an electric heater to cure the surrounding cement grout at a high temperature. Using this technology significantly reduces the curing time of the cement grout, enabling earlier confirmation of the pile's bearing capacity. Consequently, construction periods are expected to be greatly shortened, and overconstruction can be prevented.

Since 2015, LH has been applying this new technology on-site in collaboration with private construction companies such as BTENC to test optimal curing temperatures, heating methods, and smart temperature control measurement plans. After applying for new technology designation in July last year and undergoing review by the Ministry of Land, Infrastructure and Transport, this achievement marks the first new construction technology designation since LH’s founding in 2009.

An LH official stated, "We expect this new technology, developed through cooperation between a public enterprise and large, medium, and small enterprises, to become a model case of mutual growth." He added, "Going forward, we will sign a win-win agreement with co-designated institutions to promote the use of this new technology and strive to expand its overseas dissemination."
