Since middle 80s:Japanese Taogosei Co., Ltd. and
Konoike Construction Co., Ltd. have been in researching
of acrylic liquid spray waterproofing and reported their
research results in 1999 ITA annual conference.
Since the 90s：USA,Germany,Canada,Switzerland and
UK,etc developed countries also started researching
spray applied waterproofing technologies and applied in
practical projects.(Markets initiated)
