The construction materials have been updated, now plastic pipes are used in building culverts instead of the reinforced concrete pipes of the past, and stones are complemented by textile – geotextile as it is called – for reinforcing the sides of ditches.
Uuenenud on ehitusmaterjalid, näiteks kasutatakse truupide ehitamisel varasemate raudbetoontorude asemel nüüd plasttorusid ning kraavinõlvade kindlustamiseks lisaks kividele ka kangast, nn. geotekstiili.
