   What is maxit Leca?
   
3. 3. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
   maxit Leca was developed in Norway in 1958 to provide insulation to roads and railways across Scandinavia.
   It is a lightweight expanded clay formedby heating & firing natural marine clay in a rotary kiln at temperatures up to 1150 degrees centigrade.

   Why Specify maxit Leca?
   Low density and high strength combined with easyhandling makeexpanded claya highly competitiveproduct.
   
8. 8. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
   Eliminates costly settlement periods
   Reduces weight on underground voids
   Eliminates or reduces expensive load transfer techniques
   
9. 9. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
   A free draining material
   Installed using the same machinery as conventional fills
   Also can be installed pneumatically into areas of reduced or awkward access
   maxit Leca can be compacted in 1m layers, rather than 225mm as with traditional fill materials

    Any surplus product is easily reclaimed and re-utilised
    maxit Leca is not susceptible to oil or diesel spills
    Has superb insulating properties, protecting against frost
    It contains no harmful substances or gases & is absolutely neutral & chemically inert.

    Application Scenarios
    Quay Walls
    Tunnels
    Insulating Pipelines
    
12. 12. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
    When used against RETAINING WALLSmaxit Lecawill reduce the weight acting on the rear of the structure by at least 75%, in comparison to traditional fill materials. This weight reduction avoids potential failures & enables savings by increasing spacing between buttress walls & reducing structural dimensions.
    
13. 13. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
    maxit Leca's ability to reduce settlement can offer massive benefits, reducing timescales from years to a few months
    By installing maxit LWA, subsoil strengthening & lengthy settlement can be
    reduced or even avoided
    altogether.
    
14. 14. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
    Use of maxit Leca on green areas such as SPORTS FIELDS ensures optimum drainage whilst improving thermal protection thus assisting with the creation of a sympathetic
    habitat for plant life.
    
15. 15. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
    Using maxit Leca(loose or mixed with cement) to fill underground CAVITIES reduces structural forces & eliminates subsidence issues.
    By pumping high quantities of maxit LWAper day, it is possible to obtain a complete filling of the cavity with high drainage capacity, good resistance and a stiffness similar to that of the original ground.

    SKANSKAUK CIVIL ENGINEERING
    Unexpected voids were discovered behind the abutments ofa Victorian Bridge during a major 8 million project at Harthope Viaduct nr. Moffat, Scotland.
    By using maxits 55m blowing vehicle, Skanska were able to deliver maxit Leca from ground level, filling 5 voids up to 10m in depth & up to 1.5m wide in just a single day.

    How Lightweight is maxit Leca?
    
18. 18. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
    Typical Comparison
    Concrete Gravel = 2403kg.cu.m
    maxit Leca = 280kg.cu.m
    maxit Leca = 15% of the weight of traditional backfill material
