Cover blocks
Cover blocks
The Cover Blocks offered by Neelknath guarantee that the appropriate concrete cover is maintained during the concrete placing process. They are specifically engineered to raise the rebar matrix enough to allow concrete to flow below and properly embed it. They are available in a wide variety of sizes with single or double cover spacing.
These cover blocks are produced utilising proprietary processes that allow us to scale up manufacturing without sacrificing the quality of each individual unit.
