How to install an Inspection cover
Remove the cardboard corners and check if there are any damage. Place the cover in the correct position. Apply concrete fillers evenly and adequately on the edge of the frame. Make sure there are no cavitations in concrete, because these cavitations may adversely affect the density of the protective layer or bend under load.
Take into account the final finish layer. Use the level to take the cover to the right height.
Give the concrete plenty of time to harden (at least 48 hours) and open the cover when the concrete is 90% hard. Remove any concrete or other residue on the frame or recessed cover.
Apply the concrete filling to the recessed cover evenly, and place the reinforcement mesh in the right position: make sure it does not touch the bottom or sides.
Take care the height of the finish layer again.
Lay the pavers, tiles or other finish and fill the joints.
