The Heavy Insulated Concrete is a Haywire EC Unit in the Stationary Security Service game mode of Arknights, introduced in the mode's second rework and available in the Emergency Resupply mode of Acahuallan Jungle where there are three of them which may either be in the Preparation Area or among the units on the Deployment Waiting Zone at the start of an operation.
So long as a Heavy Insulated Concrete is in the Deployment Waiting Zone, friendly units have their DP cost increased by 2, which stacks if multiple Concretes are present. The Concrete can be deployed for a grand 30 DP (that is affected by the DP increase of other Concretes, but not itself), which does nothing but to make the tile it was on unusable since the deployed Concrete is invulnerable and cannot be retreated; it does not obstruct enemies' movement, however.
Heavy Insulated Concretes can only be get rid of by using Reassignment Transmitters to remove them from the available units for the operation.
