SOIL MIXING

Deep soil mixing is an in situ ground improvement method that enhances the characteristics of weak soils by mechanically mixing them with a cementitious binder. The action of mixing materials such as cement, lime or bentonite, fly ash with soil causes the properties of the soil to become extra like soft rock.

DSML provides two types of deep soil mixing for geotechnical and environmental applications, including mass mixing, and column mixing. 

Both systems present wet and dry soil mixing solutions, which enable the additives to be placed as wet slurry or dry powder. 

They are able to tackle some of the most hard soil conditions, ranging from flood plains and soft soils through to contaminated land.

SHEAR WALL CONSTRUCTION

Shear wall, in building construction, a rigid vertical diaphragm capable of transferring lateral forces from floors, exterior walls, and roofs to the ground foundation in a direction parallel to their planes. 

Examples are the reinforced-concrete wall or vertical truss. 

Lateral forces caused by earthquake, wind, and uneven settlement loads, in addition to the weight of structure and occupants; generate powerful twisting (torsional) forces. 

These forces can factually tear (shear) a building apart. Reinforcing a frame by attaching or placing a rigid wall inside it maintains the shape of the frame and avoids rotation at the joints. 

Shear walls are particularly important in high-rise buildings subject to lateral wind and seismic forces.

HELICAL PILE FOUNDATION

Helical Piles are steel shafts with a sequence of low-pitched circular steel helical plates welded at tactical positions along the shaft. 

The plates provide the foundation both tension and compression bearing capacity which enables them to be used for a broad range of applications across many industries and sectors.

The piles can be connected in groups using a steel load transfer grillage and are screwed openly into the ground by machine-mounted hydraulic or electrically powered drilling equipment. Helical Piles create the use of concrete for foundations a thing of the past.

GRADE BEAM

A grade beam or grade beam footing is a part of a building's foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons.

 Grade beam forms a great discovery in Civil Engineering Field. 

 These are used now a day’s very often.
