Expansión garantizada

Los Grouts de Five Star si se expanden estas fotos lo prueban. En la aplicación en particular de estas imágenes se ve magnificada la capacidad de expansión ya que el relleno es grande y tiene pocos orificios.

ASTM C 1339-02 video

En este video se puede ver una prueba ASTM C 1339-02 esta es del DP epoxy Grout de la marca Five Star. Este grout es excepcional puesto que tiene expansion positiva eso es mucho mejor que lo que ofrecen la mayor parte de los competidores.
