Diaphragm Walls and Bored Piles
Drilling muds play a fundamental role in the construction of special foundations, since they are key to ensure digging stability, seal borehole walls through cake formation, as well as suspend drill cuttings and fines. Drilling muds are normally prepared by mixing bentonite with water. In some instances, bentonite is replaced with polymers. We offer a full range of products to meet the needs of different types of drillings, including bored piles and digging diaphragm walls with either mechanical grabs or trench cutters (hydro mills). All our products are used in all the most important building yards in Europe, and contain no environmentally harmful substances.
