Hydraulic defence and waterlay layout

The importance of the hydraulic engineering works is now undeniable and there are various solutions that can ensure the safety of our towns and our areas.
Thanks to our experience in the field, we propose the solution that best suits the context.

The benefits of the hydraulic engineering works

The hydraulic engineering works protect against erosion, allow to control flows along rivers and protect bridges and infrastructures against floods.

Hydraulic defense works protect against erosion, enable the control of river flow and watercourses, and safeguard bridges and infrastructure from flooding. Consequently, these are critically important interventions, as they keep both residential centers and rural areas used for farming and livestock safe.

We use several types of hydraulic engineering works:

  • Structures of loose material: they consist of loose lithoid elements of different granulometry, from stone castings to earthworks.
  • Rigid concrete or reinforced concrete structures
  • Semi-rigid structures: rigid prefabricated structures, connected on site to obtain structures with a certain degree of deformability.
  • Flexible structures: these are able to face considerable deformations and subsidence of the ground without breaking or losing their protective function.

Protection against river banks erosion

The regime of watercourses and the nature of the crossed lands may not be in equilibrium conditions. That can cause erosion phenomena of the bank or of its foot, with sliding along sub-vertical walls.

The tendency of the riverbeds to assume sinuous shapes is caused by the different erodibility of the formations crossed; in general there is a relative stability of the planimetric inflection sections and a marked instability downstream of the vertices of the curves.

The limitation of the riverbed may be necessary to keep a minimum elevation in the navigable waterways.

The artificial raising of the banks allows to contain the design flood discharge in the riverbed to guarantee protection from floods.

Concrete walls are rigid structures with high mechanical strength, acting by gravity or semi-gravity.

Stone claddings are defense works made up of natural materials which are permeable and able to endure settlements without damages.

The use of rigid or flexible claddings requires laying and smoothing the ground and preparing a base made up of inert material with a draining function.

The gabion wire mesh is a permeable structure, flexible and resistant at the same time. It is able to withstand the deformations of the individual elements and the settlements and subsidence of the laying surface or of the ground back.

The metal mesh mattresses are meshes filled with stones, which protect against erosion forming a structure with high resistance to dragging actions.

The river banks subject to erosion can be covered by three-dimensional synthetic mats: the geomats.

They improve the mechanical characteristics of the ground by the insertion of elements which can develop adequate tensile strength.

Dams and civil works

Arch, gravity, concrete, earth or rockfill dams: they are some of the many types of dams! The dams are the type of works that best reflect the level of competence achieved.
They are the perfect example of multidisciplinarity and a concentrate of the various civil works we are able to realize.
