Versatile bottom flaps & manhole covers

The manhole cover is fitted with a round EPDM gasket on the bottom and a T-rubber gasket on the side of the outer frame. It prevents the ingress of contaminants. In addition, tensions between the frame and cover are avoided by the spring effect. The shaft cover is odor and waterproof. The shaft cover is not screwed tight and comes standard with a lifting key set, which makes it easier to open.

Manhole cover installation instructions

manhole cover installation instructions

1. Step: Place

Insert the closed manhole cover into the hole and carefully fill it with concrete . Make sure that there are no air pockets in the concrete, as these can subsequently affect the density of the shaft cover. Use a spirit level to bring the manhole cover to the correct height horizontally.

2. Step: Open

Allow the concrete sufficient time to harden (at least 48 hours) and open the manhole cover. Remove the remains of the concrete on the frame.

3. Step: Fill up

Is the frame clean? Then you can put the cover back into the frame. To fill the cover, first position the reinforcement (reinforcement grid). Now pour concrete carefully and evenly into the cover. Remove the amount of concrete that oozes out. Use a spatula to help

4. Step: Cover

Then cover the shaft cover with your desired slab floor. If necessary, you must prepare your floor around the shaft cover.

Slot Cover Additional Info

We always recommend opening and cleaning the installed manhole covers twice a year. The “Quick-Lifter” keys are to be used for this. The Quick-Lifters are screwed into the four intended lifting points of the manhole cover, which means that the cover can then be easily lifted using the handle of the key. This makes lifting/opening the manhole covers much easier. All bottom flaps are manufactured with 2-4 lifting points, depending on size and reinforcement.

All manhole covers are rigorously tested for quality, durability and load-bearing capacity before being released to the market. We will be happy to send you the necessary certificates on request.
