The waterway system and wet infrastructure play a crucial role in our economy. They also determine our safety, water quality and environment. We carry out projects that aim to manage and improve our waterways and wet infrastructure. <\/strong><\/p>\n

In the past, natural conditions determined the waterways. Later, all kinds of techniques emerged to manage and expand the waterway system. A well-known example in the Netherlands is the canalization or normalization of the Meuse by, among other things, the construction of wet infrastructure such as dams and locks. Constructing canals and regulating rivers by installing groynes are also well-known examples. <\/p>\n

These are activities we are good at: maintaining the depth of waterways, protecting bottoms and banks, widening channels and constructing fish passages. From both land and water, we carry out projects aimed at managing and improving our waterways and wet infrastructure. <\/p>\n

With our diverse and specialized equipment fleet, broad civil engineering expertise and innovative approach, we are able to tackle a wide range of projects. We offer customized solutions. As passionate hydraulic engineers, we enjoy contributing to improving the waterways and wet infrastructure that have shaped our past and define our future. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<\/section>\n

Een prachtig en actueel voorbeeld van ons werk is de verruiming van het Julianakanaal tussen Berg en Obbicht. Het kanaal is over een lengte van ongeveer drie kilometer verruimd.<\/strong><\/p>\n

Dit complexe deel van het kanaal heeft een nieuwe waterremmende bodemlaag en bodembescherming <\/strong>gekregen. Daarbij moesten de oostelijke oever en de naastliggende dijk gedeeltelijk worden verplaatst. Een project waarin we onze verschillende expertises hebben benut: baggeren, bodembescherming en droog grondwerk. We gebruikten zowel nat materieel (kraan- en beunschepen) en droog materieel (dumpers en hydraulische kranen).<\/p>\n

Een ander voorbeeld van de veelzijdigheid van ons werk is onze bijdrage aan de Selectieve Onttrekking IJmuiden (SOIJ). In dit project werken we mee aan de bouw van een zoutdam. Die zorgt ervoor dat overtollig zoutwater vanuit het Noordzeekanaal terug naar de zee kan stromen.<\/strong><\/p>\n

Wij hebben het waterbouwkundig deel voor onze rekening genomen met inzet van zowel nat als droog materieel. Zo hebben we gebaggerd, oude steenbestortingen verwijderd en een nieuwe bodembescherming aangebracht. Een deel van deze bodembescherming is aangebracht op een diepte van maar liefst drie\u00ebntwintig meter. Precisiewerk dat we dankzij een gedetailleerd ontwerp, een beheerste uitvoering en uitgebreide monitoring door onze surveyafdeling met succes hebben uitgevoerd.<\/p>\n

\"\"<\/p>\n


\nEen uniek stukje vakmanschap<\/strong>
\nAls de zoutdam klaar is, stroomt het zoute water door een opening op een diepte van -16 tot -23 meter NAP. Om de bodem rondom de dam op zijn plek te houden, brengt Van den Herik na het baggeren vijfentwintig hectare aan bodembescherming aan. We gebruiken hiervoor dertien zinkstukken. De grootste hebben een lengte van honderdvijfentwintig meter en een breedte van dertig. We maken de zinkstukken op het land en plaatsen ze daarna op de bodem.<\/p>\n

Remove old infrastructure<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

We not only realize, improve or replace infrastructure on and around the water. We also remove or demolish old infrastructure. Think of pipes, culverts, jetties, or works of art. <\/strong><\/p>\n

These are specialized jobs that require customized solutions, and we are good at that. Thus – to the great satisfaction of the client DPO – we have brought to the surface and removed kilometers of old oil pipelines of the Ministry of Defense on both the Hollandsch Diep and in the Maas. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<\/section>\n
