For new installations:
For a completely new helipad, before pouring the concrete, create the appropriate drainage
system. See Figure 1 on page 7 and notes.
1. Install the rubber grommets in each of the side holes.
2. Install the base can drain fittings provided (pictured below) into each base can drain
hole. Run 1-1/2" size pipe, schedule 40 PVC, into the fittings of the base can. Pipe length
should be cut so the pipe, when positioned over the drain, extends approximately 3" to
4" into the drain rock.
