Mason contractors can accomplish core filling requirements by using a masonry grout pump. Contractors have several reasons to use a grout pump for grouting masonry walls: Use a masonry grout pump when barriers on the job prevent a grout delivery system from being lifted into place. Use a grout pump to fill block walls without a forklift or telehandler. Using a grout pump is more efficient that bucketing or using grout bags. Masonry grout pumps are half the cost of a concrete pump...or less. Masonry grout pumps can be transported on a trailer or in a typical pickup truck. Contractors can use existing mixers and material silo systems with the masonry grout pump. Masonry grout pumps also pump materials directly from ready-mix trucks.
