GS Engineering and Construction said on the 1st that the 'soundproof floor structure' developed in collaboration with LX Hausys has achieved a first-class performance in both heavy and light impact sound tests conducted by the Korea Land & Housing Corporation (LH).
GS Engineering and Construction recorded 31 decibels (dB) for heavy impact sound and 27 dB for light impact sound in the floor impact sound quality test conducted by the LH Quality Test Recognition Center, obtaining first-class performance certification in both categories. The heavy impact sound measurement of 31 dB is lower than the first-class standard of 37 dB, marking the industry's lowest level.
Light impact sound refers to floor impact noise caused by relatively light and hard impacts, such as the sound of small objects falling or furniture being dragged. Heavy impact sound occurs due to heavier impacts, such as the sound of children running or large objects falling.
The newly developed floor structure incorporates 'high-density open-cell polyurethane' jointly developed by GS Engineering and Construction and LX Hausys. This new material is excellent at reducing inter-floor noise and has low moisture absorption, allowing it to maintain consistent performance over long periods. GS Engineering and Construction explained that this signifies increased construction convenience and commercialization potential.
The 'soundproof floor structure' is the result of the combined design and construction expertise of GS Engineering and Construction and the research and development capabilities of LX Hausys, according to the company. The two companies signed a business agreement in February this year to develop inter-floor noise reduction technology and optimized floor slab structures, cushioning materials, and construction methods through joint research and development.
Meanwhile, GS Engineering and Construction plans to apply the 'inter-floor noise reduction cushioning material' developed this time to strategic bidding projects in the second half of the year, including the Songpa Hanyang 2nd Reconstruction Project and the Seongsu Strategic Zone 1 Redevelopment Project, and will later expand into urban regeneration projects.
