Hola israel,
necesitaria mucho bentonita si lo mezclas con la tierra para impermeabilizar. Bentonita como impermeabilzante se use entre capas de tierra compactada. (se vende un producto, bentomat, una capa de bentomita entre capas de poliester, y 30 c. de tierra encima para compactar.
Saludos
Richard

Hi,

i have recently read that bentonite can be used to seal a surface if the soil is not a pure clay soil. I'm thinking to combine bentonite use with a macrocatchemnt or a swale to retain water in spring and summer as much as possible. Anyone have experience with bentonite? Could it be used to seal a pond too?
all the best,
israel.
