Abstract
The present invention relates to a method for manufacturing processed cork chips, and a floor construction method using the same. The processed cork chips are manufactured by the method, including: crushing and drying cork chips; adding polyurea to the dried cork chips to prepare a mixture; heating the mixture to cure the same; and cooling the cured mixture. Further, the floor construction method includes: laying the processed cork chips on the surface of a floor formed of concrete, a water-permeable base layer or crushed stone with a solidified top surface; and flattening the processed cork chips and pressing the same by means of a roller at a fixed temperature.
