GABIONS AND MATTRESSES MADE FROM FERROCEMENT
Precast units for coastal defenses, retaining walls and slope reinforcements
Argentine Patent N° 318149
Imported gabions and mattresses – Macaferri’s or a similar brand – made from galvanized steel wire are generally used to this end. They are traditionally filled with stones or rocks on the job site, which means that rocks have to be transported hundreds of kilometers, and laid by hand one by one.
Since 1994 we have implemented a new system of interlocking hollow units that are fitted together and filled with sand, soil, mud, debris or any other material available on the spot.
This system was used to build a storm water drainage system in the port of Santa Fe city in 2007, a project that was put out to tender by the City Hall (see pictures).
Our system is not only significantly less costly but also ecofriendly, since no quarry equipment or trucks are required.
The same building system and criteria can be used to build xbloc or tetrapod structures that can be filled with sand or any other material available on the spot.
