Abstract Flow collecting plot is an important component of collecting rainwater for irrigation. The ordinary impermeable materials of artificial catchments area include concrete,polyethylene film and asphalted fiberglass oil sheeting, which have high flow collecting efficiency but have some weaknesses of high cost or poor durability. The soil stabilizer applying to the flow collecting plot in water harvesting system can solve effectively the above-mentioned problems, so it is paid attention to increasingly. Based on introduction of the composition and the solidifying mechanism of the MBER soil stabilizer, the requirements of the raw material and the design of the proportion and structure, construction technique and advances are focused on that the equality, water contents and the construction time of mixture are key points of dry mixture construction technique. Finally it is suggested that plastic mixture construction technique should be enhanced.
