PolyMaster R-501 is the ideal insulation for concrete block. By top fill, side
fill, or "pressure fill." It can be installed in 10-foot to 16-foot lifts during
construction. Blocks are easily filled in either running or stacked
configurations. Pressure-fill applications require only 5/8" holes drilled directly
into masonry. Pre-expanded PolyMaster foam flows into and fills cavities, up
to 12 feet vertically from the insertion hole. Pressure filling generates a
complete fill of the core and head joints, since the foam moves unrestricted
throughout the block wall.
