To manage increased traffic flow on Highway
11 connecting the cities of Uttaradit and Denchai in the North of the country,
the Department of Highways decided to widen this route passing through
mountainous country from two to four lanes.
To avoid the need for large volumes of backfill required in conventional systems, this alternative solution involving design of appropriate Reinforced Earth® walls was a natural choice.
Working with a team of consultants, Reinforced Earth Thailand was involved at the initial phases of the project in design of the structures comprising TerraClass® facing panels with high adherence steel strips. Between 2010 and 2012, ten walls with surface areas ranging from 400 to 2000 m² were built. The total surface area is 12,000 m².
