De Vlaamse Waterweg (Flemish Waterway Authority) invested more than 15 million Euro in the construction of the new Burgemeester Eduard Waghemansbrug, better known as Brug van den Azijn. 12. 5 million were dedicated to the bridge construction while 2. 5 million for the widening of the N130 between the district of Merksem and Deurne. The project included bus lanes in both directions, a one-way cycle lane, and a pedestrian path. The abutments were designed to support a 123 m span arch bridge, approximately 16 m wide. The new bridge clearance was targeted to be 9. 1 m high, allowing the passage of ships with four layers of containers. The architects of the project designed an articulated façade for the bridge structures. Therefore, the reinforced soil walls and the true abutments were designed with a 75° inclination.

The extension project of the Corniche road in Brazzaville is part of a larger construction contract involving urban developments in the Bacongo and Makélékélé neighborhoods. The extension of the Corniche road to a 2x2 lane configuration covers approximately 5 kilometers between the Djoué Bridge and the Case de Gaulle. The route, on a slope, runs along the Congo River and requires the construction of several support structures. The technical solution specified in the contract was a patterned concrete L-wall with reinforcement of the embankment using geotextile boudins. Maccaferri proposed an alternative solution with a reinforced embankment featuring patterned concrete facing Macres®, which was favored by the company as it met the technical and aesthetic requirements of the project while significantly saving installation time and providing overall cost savings.

There is a significant erosion issue posing a risk to the stability of the area. Due to the erosion caused by a transverse culvert, the safety factors of the slope are compromised, exacerbating the situation. Additionally, the presence of a river at the base of the slope, flowing into the southern basin of Guatemala, exacerbates the problem due to flooding and ongoing rains that continue to erode the area. A protective structure with metal mesh DT is required to safeguard the integrity of the infrastructure.
