TYPE OF CONSTRUCTION
Geogrid Reinforced Soil Slope
Geogrid reinforced soil slopes are structures designed to provide stability to slopes by incorporating geogrids into the soil mass. Geogrids are synthetic materials, typically made of high-strength polymers, which have a grid-like structure with open apertures. The geogrids act as tensile reinforcements within the soil mass, distributing the applied loads and increasing the overall strength and stability of the slope. They restrain the lateral movement of the soil, preventing slope failure and potential mass movement.
Soil Nail
Soil nailing is a technique used in geotechnical engineering to stabilize slopes or excavations. It involves the installation of closely spaced, slender reinforcing elements called soil nails into the ground to improve the stability of the soil or rock mass. The specific design and construction details of a soil nail slope depend on various factors, including the soil conditions, slope geometry, desired factor of safety, and project requirements.
Hydroseeding
Hydroseeding is a method used for slope stabilization, erosion control, and vegetation establishment. It involves the application of a slurry mixture of seed, mulch, fertilizer, and tackifiers onto the slope surface using a hydroseeding machine. Hydroseeding is an effective and efficient method for establishing vegetation on slopes. It promotes rapid germination and growth of plants, reduces erosion, and helps to stabilize the slope over time.
Sabo/Check Dam
A Sabo dam, also known as a check dam or debris dam, is a structure constructed to control erosion and sedimentation. It is designed to slow down the flow of water, trap sediment, and reduce the erosive force of the flowing water. Sabo dams are commonly used in mountainous and hilly regions where erosion, sedimentation, and debris flow hazards are prevalent.
Tie Back Wall
Type of reinforced earth or soil-retaining structure that provides stability to an excavated area or a slope. It is designed to resist the lateral pressure of the retained soil or fill material and prevent slope failure. The design and construction of tie-back walls require careful analysis of site conditions, including soil properties, groundwater conditions, and loading considerations.
Gabion Wall
A gabion wall is a type of retaining wall or erosion control structure that is constructed using wire mesh baskets filled with stones or other suitable materials. It is a flexible and permeable system that provides stability, while also allowing for water drainage. They are effective in stabilizing slopes, preventing erosion, and providing erosion control along watercourses.
Erosion Mat
An erosion mat, also known as an erosion control mat, is a geosynthetic material used to prevent or minimize soil erosion in various construction and landscaping projects. It is designed to stabilize the soil surface, promote vegetation growth, and protect against the erosive forces of wind, water, and rainfall. The longevity of an erosion mat depends on factors such as the material used, environmental conditions, and maintenance practices. Some erosion mats are designed to biodegrade over time, while others offer long-term durability.
Rockfill Netting
Rockfill netting, also known as rockfall netting or rock mesh, is a type of protective netting system used to prevent rockfall and stabilize slopes in areas prone to rockslides or landslides. It is designed to capture falling rocks or debris and provide a barrier to protect people, infrastructure, and property. helps to retain soil particles, stabilize the slope, and promote the establishment of vegetation. It also helps reduce water velocity and surface runoff, minimizing erosion and sedimentation downstream.
Rubble Wall
A rubble wall is built by stacking irregularly shaped stones or rubble without mortar or with minimal use of mortar. The stones are typically sourced from on-site or nearby locations, such as quarries or excavation sites. The stones are arranged in a random pattern, and voids between the stones are filled with smaller stones or gravel. The interlocking nature of the stones provides stability to the wall. Rubble walls are commonly used for retaining walls, boundary walls, or decorative walls.
Stone Pitching
Stone pitching is a technique used to protect slopes, embankments, or riverbanks from erosion by creating a layer of stone protection. Large stones or boulders are placed on the surface of the slope or embankment in a specific pattern or configuration. The stones are typically interlocked to create a stable and erosion-resistant surface. Stone pitching helps to dissipate the energy of flowing water and protect the underlying soil from erosion. It is commonly used in waterways, coastal areas, or areas with high flow velocities.
Rock Fencing
Rock fencing, also known as rock walls or stone fencing, refers to a type of fence or boundary structure constructed using rocks or stones. It is a traditional and aesthetically pleasing method of creating boundaries, retaining walls, or enclosures using natural materials. The height and thickness of a rock fence depend on its intended purpose and the structural requirements. Higher walls or retaining walls may require thicker and wider rock structures to ensure stability and durability.
Concrete Canvas
Concrete Canvas is a patented material that combines the properties of concrete and fabric to create a flexible, cementitious composite that hardens when hydrated. It is commonly used in civil engineering, construction, and environmental applications where rapid installation, durability, and erosion control are required. Concrete Canvas is a versatile material that offers innovative solutions in the construction and civil engineering industry, providing rapid and cost-effective alternatives to traditional concrete applications.
Terramesh Wall
Terramesh is a type of modular retaining wall system that combines the stability of a welded wire mesh facing with the strength of soil reinforcement. It is commonly used for slope stabilization, erosion control, and retaining wall applications. The Terramesh system consists of the following components: Welded Wire Mesh Facing, Soil Reinforcement, Connection Components
Slope Reprofiling
Slope reprofiling means changing the shape or angle of a slope. It is done to make the slope more stable, prevent erosion, or accommodate construction projects. It involves assessing the slope, planning the changes, excavating or grading the slope, and implementing measures to stabilize the soil and control erosion. Proper drainage and ongoing monitoring are also important.
Soil Nail RC Wall
A soil nail reinforced concrete (RC) wall is a type of retaining wall that combines the use of soil nails with a concrete facing to provide stability and support to a slope or excavation. oil nails are typically long, threaded rods or bars that are installed horizontally into the soil or rock behind the wall. They are commonly made of steel and are grouted or bonded into the ground to provide additional tensile strength and resistance against slope movement.
Slope Turfing
Slope turfing refers to the process of planting or installing turf grass on a sloped surface. It is commonly done to stabilize the slope, prevent erosion, enhance the aesthetic appearance, and improve the overall ecological balance of the area. Choosing the right grass species is crucial for successful slope turfing. Factors to consider include the climate, sunlight exposure, soil type, and slope conditions. Slope turfing provides a natural and visually appealing solution for stabilizing slopes and preventing erosion.
Rockfill
Rockfill, also known as rock fill or rock fill material, refers to a type of construction material composed of large rocks or boulders that are used to fill voids or create embankments. The size and type of rocks used can vary depending on the specific project requirements. It allows for good drainage due to the voids between the rocks. This helps prevent water accumulation and reduces the risk of water-related damage, such as saturation or erosion.
Rock Netting and Rock Bolt
Netting and rock bolts are often used together as part of a comprehensive slope stabilization system. The netting provides immediate erosion control and vegetation support, while rock bolts provide long-term stability and reinforcement. The specific combination and design of these elements depend on the site conditions, slope angle, geological characteristics, and engineering requirements.
Rubble Pitching Wall
A type of retaining wall or slope protection structure that is constructed using irregularly shaped stones or rubble. Rubble pitching walls are typically built without the use of mortar or any binding material. The stones or rubble are carefully arranged and stacked to form a stable and durable wall. The stones are fitted together, often interlocking, to provide stability and prevent the wall from collapsing. The irregular shape of the stones helps dissipate the energy of flowing water and reduces the impact on the slope.
Gunite
Gunite is a construction technique used to apply a layer of sprayed concrete or mortar onto surfaces. Applied pneumatically, the material is compacted against the surface to fill cracks and fissures and prevent loose material from falling. Gunite can therefore act both as a protective coating over the slope’s surface. Gunite has excellent compressive strength and durability, making it suitable for a wide range of applications. It forms a dense and strong layer that can resist various forces, including impact, weathering, and water penetration.
