Soil is a super abundant natural building material which is available on
most sites at little or no cost, yet, quite useless if allowed to turn to
dust or mud.
Ecobond hardened soil dramatically increases the water resistance and
strength of soil creating a new, cost effective and durable building material.
Approximately 3% Ecobond combined with most soils dispels the inherent
flaws of soil and transforms it into an excellent building material for the
construction of roads, houses, dams and many other applications. Ecobond
works well with most soil types, preferably less than 20% clay, Ecobond does
not glue rocks together, a finer aggregate is required between rocks.
Since soil can be transformed into a useable and durable building
material, Ecobond can be used to construct high quality roads at very low
cost. In this application (see image), the on site soil was combined with
Ecobond, compacted and a 6mm bitumen slurry was used to seal the road. The
road has carried more than 15 million vehicles (1000 large trucks per day)
since 1996. The completed road costs considerably less than a conventional road.
Ecobond can be used in many fields as a new low cost solution:
Roads:
Vastly improved bearing capacity and weather resistance of gravel or
surfaced roads, driveways, parking lots, yards, pavements, paths and pothole
repairs, etc.
Structures:
Walls, floors, foundations of houses, schools, clinics, offices,
factories, shops, sheds, embankments, and support structures.
Water Storage:
Dams, ponds, canals, tanks, waterproofing, riverbanks, dykes, erosion and
mud control.
Stabilisation:
Embankments, railway lines, dust control, underground grouting, tunnels,
basements, fence posts, pylons, poles, pipes, surface coatings, landing
strips, sports fields, military, waste/pollution control, artificial rocks,
statues or decorative features.
