BOLLARD LAYING PROCEDURE
Proceed with the realization of the drain of the
rainwater through the lay of a PVC pipe with
100mm diameter. This pipe must be connected
to the sewer system or in alternative to a well
equipped by an emptying system with a greater
depth.
Insert gravel with grain 22/32 mm diameter and
220m height. In order to avoid “retreats of settling”,
it is advisable to compact the gravel.
Insert a geotextile layer (gr. 300) on the compacted
gravel.
The size “ h ” are very important to ensure
that the formwork protrudes 20mm from the
trampling line.
