CEMEX delivers 48,000 m3 of concrete for major underwater maritime project in Germany

Date published: June 8, 2011

From 2008 to 2011, CEMEX in Germany ensured the continuous supply of approximately 48,000 cubic meters of ready-mix concrete for the new construction of Kaiserschleuse Bremerhaven, one of the largest lock projects in Europe. The newly completed Kaiserschleuse lock for auto carriers is 305 meters long, 55 meters wide, extends 13 meters below sea level, and is designed for high water of over 6.5 meters.

The international port of Bremerhaven is the predominant transshipment point for motor vehicles in Germany. Its only connections to the river Weser, a major German transportation artery, are the Kaiserschleuse and Nordschleuse locks.

While the Nordschleuse lock continues to meet shipping requirements, the old Kaiserschleuse lock, built in 1897, was too short and narrow for today’s ever larger and wider vehicle transportation ships. It could only handle ships measuring up to 185 meters long and 25 meters wide, when modern auto carriers are far longer than 200 meters. Consequently, over the past few years, the larger Nordschleuse lock was the only point of entry to the port’s quays for more than 1,000 ships, loaded with more than 2 million motor vehicles.

Now, with the completion of the new Kaiserschleuse lock, the bottleneck at the port is solved. The two locks not only allow for a constant flow of ships today, but also ensure adequate capacity for the forecasted continuous growth of the port of Bremerhaven.

A supply association under the aegis of CEMEX in Germany ensured the continuous supply of the construction site with ready-mix concrete on behalf of the Kaiserschleuse consortium. The scope of products delivered included, among others, underwater concrete, concrete for components exposed to frost and de-icing salts, and structural high compressive strength concrete. Moreover, a specific ready-mix concrete was produced for alternating wet and dry areas in the water exchange zone, where fluctuating water levels create greater abrasion.

As a leading provider of building materials in Germany, CEMEX provides its customers with the reliable, high-quality service and consistent product quality they demand. Through a country-wide network of five cement plants, 41 aggregates quarries, and nearly 200 ready-mix plants, the company stands ready to deliver innovative solutions to their clients’ specific challenges whenever and wherever they are needed.
