Earthworks in infrastructure and road construction
Lightweight construction with foam glass gravel is the modern solution for building on poor ground. MISAPOR sustainably relieves the load on the subsoil and forms a load-bearing layer for the superstructure. The mineral lightweight fill is also frost-resistant and highly draining – properties that reduce maintenance and save costs.
Characteristics
In contrast to conventional methods, the lightweight construction method saves time and material costs. Due to the low weight of the foam glass gravel, even the smallest replacement quantities are usually sufficient to relieve the soil in the long term.
Dams / protective walls
The lightweight foam glass gravel from MISAPOR is the ideal problem solver for dam construction and the construction of protective walls. MISAPOR offers adequate and cost-effective solutions, especially for subsoils with low load-bearing capacity. The low weight and the weight stability provided by optimum water drainage reduce or prevent subsoil deformation. MISAPOR also does not react to freeze-thaw cycles and thus effectively prevents the effects of frost.
Characteristics
- Ideal for adapting the load to the load-bearing capacity and stability of the substrate.
- Reduction or prevention of settlement and other deformation damage to nearby structures
- Reduction or avoidance of soil replacement measures
- Shortening the construction time
- Reduction of interventions in nature
Backfill
Whether as lightweight fill, backfill or static relief – MISAPOR always offers the optimum solution. The innovative building material is not only ultra-light (from 115 kg/m3), but also weight-stable thanks to its excellent seepage performance. MISAPOR foam glass gravel was used, for example, for the cross-city link C in Zurich.
MISAPOR makes building easy. Thanks to its low weight, it is suitable for lightweight fillings of all kinds, for embankments, slopes and backfills as well as for surfaces that can be walked or driven on.
Characteristics
- Low and stable weight without water absorption
- Fast water drainage thanks to excellent longitudinal and transverse drainage
- Quick and easy installation
Widening or raising dams
Widening and raising existing road embankments is problematic if the subsoil settles more strongly under the load of the new embankment. Settlement differences and entrainment settlements occur in the cross-section of the existing embankment, which can lead to changes in the transverse slope and longitudinal cracks in the superstructure. The use of foam glass gravel fill during widening and raising can reduce the base pressures and the resulting differential settlements as well as the entrainment settlements on the existing embankment (source: FGSV information sheet, 2016 edition).
Characteristics
- Ideal for adapting the load to the load-bearing capacity and stability of the substrate.
- Reduction or prevention of settlement and other deformation damage to nearby structures
- Reduction or avoidance of soil replacement measures
- Shortening the construction time
- Reduction of interventions in nature
Restoration of subsidence damage
Stably absorbing dynamic loads on poor subsoil – here too, the solution is MISAPOR. The low load-bearing capacity of the subsoil entails the risk of subsoil deformation and reduced serviceability of roads and traffic areas, and thus also high subsequent costs. MISAPOR foam glass gravel combines properties that allow for a construction method that is around 10 times lighter and thus greatly reduces or even completely eliminates these risks.
The FGSV M SGS information sheet published at the end of 2016 ranks in the category of regulations 2 and shows possible applications for foam glass gravel fills in the substructure of roads and traffic routes and provides information on application according to the current state of the art.
Characteristics
- Floor relief
- Quick and easy installation
- Frost foundation thanks to thermal insulation
- Weather-independent installation
- Can already be driven on during installation
Railroad line
MISAPOR foam glass gravel often solves several challenges at once, even in civil engineering and road construction. Low weight, high compressive strength, high load-bearing capacity – and all in just one work step.
The railroads also like it, because MISAPOR also holds up under the tracks. In Seewen, for example, the connecting tracks were underlaid with a lightweight fill made of specially pressure-resistant MISAPOR in layers of 30 cm each. A fleece also prevents mixing with other materials.
As versatile as the requirements are, we solve the specific challenges flexibly. Of course, processing remains simple, fast and uncomplicated.
Characteristics
- Tested and proven for suitcases on poor ground
- Ideal for lightweight fills with the highest load requirements and dynamic force effects
- Extremely high stability
- Exceptionally good long-term settling behavior
