MacGrid are used for construction of MSE wall/slope or repairing of failed slope using variety of facing system.
Type of fascia system:
• System Terramesh/Green Terramesh
• Concrete
• Wrap Around Masonry
• Block
Advantage of Maccaferri MacGrid:
• Flexible structure
• Easy installation
• Maximize land usage
• Environment friendly
• Guaranteed product quality
• Cheaper compared to conventional method
• Can be constructed in difficult site condition
• Virtually structure can be constructed to any height
Reinforced Embankment
Construction of embankment on top of unstable foundation soil are made easier using high strength MacGrid which acts as a basal reinforcement element to resist force and maintain the support until the foundation soil has increased in strength sufficiently to support the embankment on its own. The following properties of the MacGrid are essential for this application:
• Geogrid must be flexible, for easy installation
• High pullout resistance with rough surface
• High short term stress strain characteristic
• Low creep with high LTDS
Sub-Grade Reinforcement
The use of geogrid as sub-grade reinforcement application has been proven to be economically viable. The geogrid is installed within the granular sub-grade course to increase modulus of the structure. The load-carrying capacity of the pavement system is transferred to the geogrid material. Followings are the advantage of MacGrid for Sub-grade reinforcement application:
• Minimize excavation depth to remove unsuitable foundation soil thus reduces the required aggregate thickness to stabilize the sub-grade.
• Minimize differential settlement of the structure.
• Increases life expectancy of the structure.
Pile Embankment
High strength geogrid acts by transferring the loads from the soil arch between the piles into the adjacent piles. The availability of high strength geogrid up to 1200kN/m allows designers to increase the spacing between the piles and this reduces the total number of piles required in an embankment. Since piles are expensive component of the whole system , any reduction in the number of piles can offer significant savings on the total project cost. Simple construction method and faster completion shortens the overall construction period of a project compared to conventional method of concrete slab. Formwork preparation, steel reinforcement installation and concreting works by skilled labors are replaced with mechanical installation of geogrid with a couple of well trained labors.
