Application of Liner for Building Construction
The Liner for Building Construction has many applications that are available for every construction industry. Starting From roads to buildings, contaminated sediments to stormwater retention, Macro Sheet India Limited helps in designing, delivering, and implementing the requirements of the geomembrane lining for all construction projects.
- LIQUID BARRIERS: By installing Geomembrane Liner for Building Construction all around the building’s base can help mitigate water infiltration. In addition to that, it also protects from mold, mildew, and structural damage.
- GAS | VAPOR BARRIERS: In some countries, methane and radon gas migrate through the floor into commercial and residential buildings. Airing to these harmful gases can be reduced by installing liner for Building Construction above or below a building’s concrete foundation, which results in sealing it from the surrounding vapor.
- ENVIRONMENTAL BARRIERS: The use of HDPE sheets can shed water from an area until all pollutants are removed and safely transferred offsite to protect against further environmental impacts.
- Subgrade Stabilization: The Liner for Roads Construction can be used to stabilize the subgrade by preventing the migration of fine particles. It reduces the risk of settlement and unevenness in the road surface.
- Erosion Control: The Liner for Roads & Bridges Construction can be utilized in areas prone to erosion, such as embankments and slopes. To prevent soil erosion and maintain the stability of the road structure.
- Moisture Barrier: Liners act as a moisture barrier, preventing water infiltration into the road layers, which helps in maintaining the structural integrity of the road and preventing damage caused by water.
- Separation Layer: Liners can be used as a separation layer between different road layers, preventing mixing and enhancing the performance and longevity of the road.
- Containment of Hazardous Materials: In cases where roads are constructed for the transportation of hazardous materials, liners can be employed to contain any potential spills or leaks, preventing environmental contamination.
HOW TO USE FOR CONSTRUCTION OF ROADS?
- Serves as a base liner or is placed under tar and other road constructions and serves as a seepage barrier.
- THICKNESS REQUIRED: - 0.75 mm, 1.00 mm, 1.25 mm & 1.50 mm
HOW TO USE FOR BUILDING CONSTRUCTION?
- Macro HDPE Geomembrane can be used as a water proofing membrane which can be laid on a surface. Doesn't let water out of it. It can be laid under structural slabs, foundations, flat roofs and finishing tiles. Ensures that water does not seep into the structural slab.
- On a flat roof, Macro HDPE Geomembrane Liner for Building Construction can be placed over structural slabs and under tiled finishes as a water proofing membrane. This will ensure that water does not seep into the structural slab. Tiles and geomembrane should be placed over a filler material that is sloping to ensure that water flows down sumps and drains. Any water that remains as puddles on top of the tiles is likely to seep into the slab over time, so puddles should be avoided at all costs.
- Geomembrane liners also play an important role in construction. When moisture seeps into walls, ceilings or building foundations, it creates and develops severe structural damage over time. Geomembrane Liner for Bridges Construction act as a barrier, preventing moisture from entering the walls and foundation of the building. In turn, this prevents mold, mildew and fungus from growing. Geomembrane liners can also prevent hazardous chemicals from leaking into the soil or groundwater beneath a building's foundation. Not only is this an eco-friendly solution, but it can also save on the cost of building repairs down the road.
ADVANTAGES
- The possibility of attack of aggressive agent by soil watering is avoided.
- Mixing of sub base material with freshly laid concrete is avoided.
- The friction between the concrete slabs reduces the force and helps in the movement of the concrete slab.
- Acts as a vapor barrier and prevents water from the concrete mix from sinking into the sub base.
The Operations of Liner for Roads & Bridges Construction
The operations of Liner for Roads Construction is defined by four discrete functions such as separation, filtration, drainage, and reinforcement. Depending on the application, the Liner for Bridge Construction can perform one or more of these functions simultaneously.
Separation: The flexible porous Liner for Roads & Bridges Construction is placed between the two different materials so that the integrity and function of both materials can stay intact and be improved. During the transportation of the application, separation means the role of the liner in protecting from intermixing of two soils.
Filtration: The equilibrium geotextile-to-soil system that allows for adequate liquid flow with limited soil loss across the plane of the geotextile liner over a service lifetime compatible with the application under consideration. To perform this function, the HDPE liner needs to satisfy two conflicting needs. The filter’s pore size must be small enough to retain fine soil particles, while the geotextile material should permit a relatively unimpeded flow of water into the drainage media. A common application elaborating the filtration function is the use of a geomembrane in a pavement edge drain.
Drainage (Transmissivity): This means that the capability of the thick Liner for Bridge Construction which is having a three-dimensional structure offers an avenue for the water flow through the plane of the geotextile liner.
Reinforcement: This is the synergistic improvement in the total strength which is created by the introduction of Liner for Building Construction, mainly due to three mechanisms: the first is with the lateral restraint through interfacial friction created. Second, it forces the potential bearing surface failure plane to develop at an alternate, higher shear strength surface. And the last mechanism is, the type of membrane to support the wheel loads.
Liner for Roads Construction
Macro HDPE Sheets play a crucial role in road construction by maintaining the longevity of roads and improving the drainage system. They separate the aggregate from the finer soil below, preventing sub-grade movement and ensuring smooth and efficient journeys.
In concrete roads, bridges, and slabs, the Liner for Roads Construction acts as a barrier between the soil and concrete. It prevents the wastage of cement sludge and enhances the structural integrity.
By providing a protective layer, these sheets help strengthen the roadways and contribute to their long-term durability. Macro HDPE Sheets are essential components in road construction, ensuring the stability, drainage, and overall performance of road systems.
