Expansion shells hold in any rock strata which is sufficiently competent to provide an adequate anchorage.

They are designed to anchor in soft ground or hard rock.

In good strata the anchorage exceeds the ultimate strength of the steel bolt.

All expansion shells require a competent strata in the anchor zone.

The suitability of the anchorage and the specific expansion shell to be used is best determined by physical load testing.
