Constructing the Plug Seal

The StrataCrete Plug Seal is ideal for areas with weaker, softer coal ribs because the increased coverage of the seal helps to stabilize the ribs. It is also best suited for areas that are not expected to encounter significant ground convergence.

It is designed for mine openings ranging from 2.5 to 16 feet high and 16 to 40 feet wide, with typical thicknesses of 8.5 to 10.3 feet (2.5 to 3 metres).
