строительный песок(Bricklayer's sand is the ideal mix for cement in pointing, paving and brick laying projects, available from Springbridge in smaller bags perfect for smaller projects. Bricklayer's sand is "soft sand' which is unsuitable for horticultural purposes as it is too fine and will clog soil particules. You can use 'sharp sand" which is useful for breaking up heavy soils and improving drainage. Alexander Demidov)
