GS Construction Develops Korea's First 5-Layer Floor Structure to Reduce Interfloor Noise

[Asia Economy Reporter Kim Hyemin] GS Engineering & Construction has developed the country's first '5-layer floor structure' to reduce noise between apartment floors.

GS Engineering & Construction announced on the 18th that the Eco-friendly Architecture Research Team at the GS Yongin Technology Research Institute developed this technology and filed a patent. The 5-layer floor technology, which applies a triple wet floor method to prevent noise between floors, is the first of its kind developed in Korea.

This technology realizes a 5-layer floor structure by applying three wet processes?base layer, intermediate layer, and finishing layer?to the floor finishing of individual apartment units. The newly developed 5-layer floor structure focuses on increasing the floor finishing thickness above the concrete slab from the existing 110?120 mm to about 140 mm and applying a high-elasticity cushioning material. After constructing the base layer on the slab through a wet process, the high-elasticity cushioning material is installed, the intermediate layer is treated with a wet process heavier than lightweight concrete, and finally, a cement mortar finishing layer is applied, creating a total of five floor layers.

In particular, by adding the base layer, floor flatness is secured, improving the construction quality of subsequent processes while maximizing weight without reducing the thickness of the cushioning material, intermediate layer, and finishing layer.

Earlier, GS Engineering & Construction received a first-grade rating from the Korea Conformity Laboratories (KCL) in January this year for its self-developed 4-layer floor structure. The newly developed 5-layer floor structure is designed to further enhance noise reduction between floors and ensure quality and constructability when applied to large-scale construction sites.

A GS Engineering & Construction official said, "Although various noise reduction technologies between floors have been developed domestically, many remained at the testing stage due to construction quality issues and were rarely applied to actual apartment construction sites. The 5-layer floor structure is a technology that meets both the requirements of being applicable to large-scale apartment sites and maintaining floor quality continuously."

Additionally, GS Engineering & Construction has completed patent registration for a 'vibration isolation mount floor structure' that can reduce floor impact vibrations. This technology applies vibration isolation mounts, generally used on machine room floors, to apartment floors to significantly reduce noise between floors.

The noise reduction method developed by GS Engineering & Construction has completed the demonstration phase at apartment sites and is undergoing performance improvement work. Once certified, it will be sequentially applied to new apartment construction sites.
