Summary:PROBLEM TO BE SOLVED: To reduce the dispersion of strength in a substrate material for construction and prevent a waterproof layer and a bumpy layer from being dried and cracked and peeled. SOLUTION: In this substrate material 1 for construction, the waterproof layer 3 is formed on the surface of a substrate 2, and a bumpy layer 4 is formed on the waterproof layer. A fiber board having a water absorbing length change rate of 0.30% or less in the longitudinal and crosswise directions of a plate material is used as the substrate. A medium density fiber board (MDF) manufactured by a dry process is desirably used as the fiber board. COPYRIGHT: (C)2007,JPO&INPIT
