World record with ground limestone

They couldn’t be transported by lorry: the longest prefab box girders in the world for the Lienebrug Bridge in Wanssum. These 'mega-girders' are a whopping 69 metres long and weigh 256 (!) tonnes.

The 8 box girders were transported from our client’s production site to Wansum by boat. The high-quality concrete products were produced using Winfill 700 type ground limestone. Using Winfill 700 results in a very dense concrete, thus guaranteeing its high strength and adherence to sustainability requirements. De Hoop Bouwgrondstoffen delivers this high-quality ground limestone with a consistent quality and colour, and it is produced according to the strictest production requirements.
