PURPOSE: A structure of the bottom of a children's playground and a construction method thereof are provided to prevent corruption of inner bottom materials by preventing water penetration from the outside, to dry in short time, and to utilize for long time without repair by maintaining elasticity for long time because impact from the top surface is evenly distributed. CONSTITUTION: A method for constructing the bottom of a children's playground is as follows. The bottom surface where a playground will be placed is cleaned so that a base layer is formed(S200). An elastic material of 2 liquid type state of main materials and a hardening agent are spread on the top of the base layer so that a flexible elastic layer is formed(S210). A cutoff layer preventing moisture absorption is formed in the top of the flexible elastic layer(S220). Rubber chips are spread on the top of the cutoff layer so that a surface layer is formed(S230). |
