CYH-500

CYH-500  is a hydrophobic grout based on polyurethane. Upon  contact  with  water  CYH-500 reacts  to  flexible  closed  cell  rubber-like  foam while  expanding  its  volume  up  to 30 times.  The cured  flexible  material  is  of  a  constant  volume. Since  water  is  not  a  component  of  the  foam structure,  the  cured  material  is  essentially  not affected by water or dryness. The reacted material does not shrink or swell.  Depending on the pressure of injection CYH-500 reacts to a  very dense and flexible material or foam.
