Because of the amount of non-sealed induced contraction joints, it is necessary to count with a grave base that is less susceptible to water, which shall be able to reduce pumping probability and, consequently, reducing step faulting.
Debido a la cantidad de juntas de contracción sin sellar es necesario tener una base granular que sea menos susceptible al agua y que reduzca al mínimo la probabilidad de bombeo y por ende escalonamiento.
