| DIAPHRAGM WALLS | ||
 |
Foundation walls formed and cast in place by excavating contiguous trenches, using the slurry trench method. These walls can simultaneously function as temporary and permanent structural walls, load bearing elements and water cut-off walls thus providing a permanent structural element that marries with and enhances structures. Their plan geometry may vary to optimise the structural requirements. | |
SLURRY TRENCHES |
||
 |
Cut-off executed by the bentonite slurry method and filled with cement-bentonite, soil-bentonite or plastic concrete to form a continuous barrier. Their main uses are to limit the migration of liquid or gaseous contaminants, to allow a localised lowering of the water table or to stabilise existing and future slopes. | |
 |
Vertical or inclined structural elements transferring loads from a structure to different soil strata. Piles are used to negotiate compression, tension and horizontal/shear forces. Piles can be bored, driven, drilled or pushed. Driven piles can be wood, pre-cast concrete, steel or composite. They can transfer loads by end bearing, friction or a combination of the two. Piles can be cased (temporarily or permanently) or uncased. | |
 |
Small diameter piles used primarily to stabilise existing deteriorating structures or increase the stability of existing ones. Micropiles can either be vertical or inclined and can be designed to resist compression, tension or a combination of these forces. The limited size of equipment needed to install these piles suits perfectly difficult access or limited headroom locations. | |
JET GROUTING |
||
 |
Soil replacing and mixing system creating engineered soil element(s) by eroding, under very high hydraulic pressure, the surrounding soils and substituting the issuing materials with bonding ones. A very flexible technology capable of enveloping obstructions and being executed in confined places. It is mainly used to stabilise, improve or transform existing soils into more manageable and structurally improved ones. | |
MARINE WORK |
||
 |
Civil engineering foundation works executed at ports or about waterways. Drilled, driven and steel sheet piling are used for constructing dolphins, fenders, bulkheads, covers for scouring areas, diffusers and water intake. | |
GEO-JET WALLS |
||
 |
Mechanical mixing of soil with the addition of cement slurries under high pressure to form lateral supporting barriers. It is possible to incorporate H-beams or other structural steel elements into the freshly mixed soil to enhance the characteristics of the cut-off. | |
LIME COLUMNS |
||
 |
Improve the properties of most types of soft soils with high water content using a dry binder is more suitable for widespread loads than highly concentrated loads. The most frequent application is road and railroad embankments, parking lots, light indistrial buildings and excavations. as the soil is improved, its strenght, stiffness and modulus increase. | |
 |
Lateral supporting systems composed of drilled or driven modular vertical elements self-supporting or stabilised by horizontal or inclined structural elements conceived to allow local excavations in the vicinity of existing structures. | |
 |
Methods of stabilisation of existing structures engineered to the conditions in hand. Used mainly where excavation in urban areas require shoring up streets and existing construction; and, when additional loads are added to existing structures. | |
