soil stabilization service.

Providing Soil Nailing and Slope Stabilization Services for permanent or temporary stabilization of excavated slopes, embankments, and retaining structures using in-situ soil reinforcement techniques.

The work includes:

• Surveying and marking of nail locations and drilling of boreholes to the required depth and inclination using suitable drilling rigs.

• Insertion of high-yield steel reinforcement bars (nails) of specified diameter and length into the boreholes.

• Grouting of boreholes with cementitious grout under controlled pressure to ensure full encapsulation and bond between soil and nail.

• Fixing of bearing plates and nuts at nail heads after grout setting.

• Application of shotcrete / guniting over the slope surface with wire mesh reinforcement to form a protective facing.

• Drainage arrangements including weep holes to relieve pore water pressure.

• Includes all materials, labour, machinery, grouting equipment, scaffolding, and safety measures required for complete execution as per approved drawings and direction of the Engineer-in-Charge.

 AES Soil nails and rock bolts drilling and fixing work involves reinforcing and stabilizing slopes, retaining walls, and excavated surfaces to prevent soil and rock movement. This technique includes drilling holes into the unstable slope or rock face and inserting steel bars, which are then grouted in place to create a bonded structure. Soil nails are generally used in softer ground conditions, while rock bolts are employed in harder rock formations. The installation process begins with precise drilling to the required depth, followed by the insertion and securing of the steel nails or bolts. Once in place, these elements act to restrain the movement of soil or rock by providing tensile strength and anchorage. This method is vital for maintaining the stability of cut slopes, highway embankments, tunnels, and other infrastructure projects, offering a cost-effective and efficient solution for ground reinforcement and landslide prevention.

Providing and fixing Rock Fall Protection Netting on hill slopes to prevent the movement and falling of loose rock fragments, ensuring the safety of structures, roads, and work areas below.

The work includes:

• Surface cleaning and removal of loose materials from the slope prior to installation.

• Supply and installation of high-strength double-twisted galvanized steel wire mesh / PVC-coated steel wire mesh of approved make and specification.

• Anchoring of the net using suitable rock bolts, anchor bars, clamps, and boundary ropes/wires, ensuring firm fixation to the slope.

• Overlapping and jointing of adjacent nets to provide continuous protection without gaps.

• Provision of top and bottom support ropes, intermediate anchors, and tensioning to achieve the required tightness.

• All materials, labour, tools, tackles, safety gear, and equipment required for proper completion of the work as per approved drawings and instructions of the Engineer-in-Charge.

Providing Coastal and River Bank Protection Services to prevent erosion, scouring, and structural damage caused by water currents, waves, and tidal actions, ensuring the long-term stability of shorelines, embankments, and adjacent infrastructure.

The work includes:

• Survey, site preparation, and excavation to required lines, levels, and slopes as per approved drawings.

• Construction of protective systems such as revetments, gabion walls, stone pitching, rip-rap, geobag / geotextile installations, and toe protection works as per design requirements.

• Placement of filter layers or geotextile underlayers to prevent soil migration and ensure adequate drainage.

• Execution of scour protection and energy dissipation measures including launching aprons, berms, or retaining layers.

• Compaction, grading, and finishing of slopes and embankments to the designed profile.

• Includes all materials, labour, tools, equipment, machinery, and safety measures necessary for complete and satisfactory execution as per approved specifications and direction of the Engineer-in-Charge.

Providing and installing Rockfall Barrier Systems designed to intercept, absorb, and contain falling rocks and debris from steep slopes, thereby ensuring the safety of roads, structures, and work zones below.

The work includes:

• Survey and site preparation for installation of rockfall protection systems as per approved design and drawings.

• Supply and installation of flexible rockfall barriers consisting of high-tensile steel wire mesh or ring net panels supported by steel posts, base plates, and energy-absorbing devices.

• Foundation works, including drilling and grouting for anchor installation and placement of base supports.

• Erection of posts and tensioning of ropes/cables as per manufacturer’s guidelines to achieve the designed energy absorption capacity.

• Fixing of nets, connection elements, clamps, and brake rings ensuring proper overlap and tension across panels.

• Includes all materials, labour, tools, equipment, scaffolding, and safety measures required for complete and safe execution as directed by the Engineer-in-Charge.
