Stability is key

  • Creating a solid foundation is vital when it comes to building quality roads that last the distance
  • Stabilisation is the process used to create solid foundations using lime, cement and foam bitumen to chemically change and enhance the existing materials
  • Lime can be used to increase load-bearing capacity, make an impermeable base layer and repair an existing road structure

Graymont's Lime in the mix

  • Lime can dramatically improve the soil engineering by reducing moisture capacity, plasticity and swelling
  • Lime is spread then watered (slaked) to form calcium hydroxide and mixed into the subgrade soils creating a pozzolanic reaction. Lime reacts with the alumina and silica found in many clay soils
  • Depending on how reactive the soil is, impressive strength gains can be obtained

Key benefits

By using lime to stabilise the existing sub base, the following advantages may apply:

  • Cost-savings achieved by utilising existing materials
  • Reduces the need to import new materials, which is environmentally sound and improves speed of construction
  • Shorter construction periods = less traffic congestion and disruptions in urban environments

Graymont is New Zealand's largest lime supplier, so we've been supplying roading contractors (and farmers) with quality lime products for many years:

  • You can always be assured we'll have the product and quantities available
  • We can also put you in touch with the right soil testing labs to make sure you get the ideal mix for your soil and get the strongest stabilisation results
