	Road drainage
	Rainwater, which strains through the permeable surface and is absorbed by the structure supporting the road, will damage the stability of the road itself. In these cases, road drainage must be laid longitudinally along the roadway edge and in the centre of the traffic divider to remove water infiltrations. It need operating so that the underground water is collected and eliminated by the drainage pipe, the only effective drainage road to guarantee permanent results. Almost all cracks on the road surface are due to water infiltrations resulting in the instability of the underlay supporting the roadbed and that produce the necessity to arrange road drainage produced by Polieco since many years.
