PUMP-X53 is a multi-purpose, low modulus, moderate strength filler used for filling cavities, voids and cracks from a minimum of ¼" width up to approximately 18 inches. PUMP-X53i is an ultra-fine, moderate strength micro-injection grout which achieves high flow for efficient filling of small cracks and voids from a minimum width of approximately 1 mm to as much as several inches in thickness. Pump-X 53iE is an ultra-fine, expanding, non-polymer cementitious injection grout designed for filling small cracks and voids in sound concrete and masonry construction. Slight expansion after placement and before final set enables the material to force itself into close, positive contact with internal crack surfaces, where desired. PUMP-X-53iL is a softer, non-polymer, hydraulic lime grout, for use in Historic masonry restorations requiring repairs to lower strength brick and softer stone elements.
