Sampyo Industry "We Will Tackle Apartment Floor Noise"... Launch of High-Performance, High-Density Mortar

Strengthening Mortar Layer Thickness from 40mm to 70mm
Increasing Mortar Density by Using High-Density Aggregates

Sampyo Industry has introduced a mortar that can reduce noise between apartment floors.

On the 5th, Sampyo Industry announced the launch of two types of high-performance, high-density mortar products developed to reduce noise between floors.

The newly developed mortar eliminates the aerated concrete layer in the existing floor structure and strengthens the mortar layer thickness from 40mm to 70mm. The most notable feature is the change from water-absorbing aerated concrete to a cushioning material that does not absorb water.

When mortar is applied directly on the cushioning material, ordinary mortar is likely to crack. In contrast, Sampyo Industry explains that the high-performance mortar reduces water separation, offering excellent crack resistance and allowing for a solid finish.

The high-density mortar uses high-density aggregates to increase the mortar density per unit area. It can replace existing mortar for construction (40mm) or be applied by increasing the mortar layer thickness (70mm) on site. Using high-density aggregates results in noise reduction effects due to resistance to vibration and impact. Additionally, it uses less water compared to ordinary mortar, providing superior durability and crack resistance.

Sampyo Industry is responding to increasing demand by establishing the Sejong plant in 2021, capable of producing 850,000 tons of mortar annually, following plants in Incheon, Hwaseong, and Gimhae.

A Sampyo Industry official said, “The mortar developed this time is the result of Sampyo Industry’s unique technological competitiveness and know-how in the concrete field, and it is expected to dramatically improve noise reduction between floors and workability.”
