What is maxit Leca?
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.

What are suitable applications for maxit Leca?
5. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
Drainage
Protecting and insulating service pipework
Reducing the loads against retaining walls
Stabilising slopes
Biofilters
Void Filling
6. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
Lightening the loads on bridge abutments
Minimising earth settlement
Lightweight insulating material in any number of Civil Engineering
Applications
7. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
Why Specify maxit Leca?
Low density and high strength combined with easyhandling
makeexpanded claya highly competitiveproduct.
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. 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
10. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING
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. 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. 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. 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. 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. 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
