Websters Burnt lime (Calcium Oxide) is sourced and manufactured onsite from a high quality deposit. Our Burnt lime is tested in our onsite lab to ensure the product maintains a high standard.
Burnt Lime is used extensively in the building and construction sectors but is also very effective in a number of agricultural applications.

• Roading and construction: Lime stabilisation has been around for centuries, it is an efficient and cost effective way to improve the workability and load bearing characteristics for a variety of different applications.
  The two main benefits in lime stabilisation is the drying effect it has on wet soils commonly utilised in the building industry on wet access roads and building pads reducing their down time. The most important benefit is substantially increasing the load bearing characteristics of your subgrade while still maintaining a level of flexibility, particularly effective on clay soils typical in Hawkes Bay and around New Zealand This is why Burnt lime is used throughout New Zealand for stabilising our roads.
• Bio solid treatment: Burnt Lime is effective for speeding up the natural decomposition process, hugely effective for neutralising and drying back bio sludge material before disposal.
  Burnt Lime will actively kill bacteria and germs, which helps in the purification process and once the PH level is increased and the germs killed off Burnt Lime significantly reduce odours. (Great for offal pits and septic tanks)
  Hydrated lime has the added benefit of absorbing heavy metals further reducing the toxic nature of bio solids before they are dumped.
• Agriculture: Burnt lime is a very effective PH correction tool, more so than agricultural of hydrated Lime. It is often used to give a spike in PH killing bacteria or “sterilising the soil” effective if the area is prone to bacterial diseases. Used extensively in Brassica production as an effective tool for preventing club root.

Websters Hydrated Lime is sourced and manufactured onsite from a high quality deposit. Our hydrated lime is tested in our onsite lab to ensure the product maintains a high standard.
It is a hugely versatile product being utilised for a number of industrial purposes, being a natural nontoxic product hydrated lime is ideal in a number of applications, where harmful chemicals may be employed.

• Water treatment: Hydrated lime is an effective flocculent, removing course material by forming a fluffy charged solid that aids in removing smaller particles from water, leaving you with a clear pond after settlement. In municipal water treatment once Hydrated Lime is added to water it will raise the PH level neutralising any acids, this will help maintain healthy pipes, Hydrated Lime will actively kill bacteria and germs, which helps in the purification process.
• Wastewater: Hydrated Lime absorbs heavy metals and phosphates as well as neutralising Hydrogen sulphide, which cause a lot of the smell.
  Hydrated lime assist in the settling process, which reduces the detrimental effects commonly associated with wastewater over flows.
  Hydrated Lime is ideal for treating effluent ponds created for intensive farming operations, leaving you with a product that is more beneficial when used as a fertiliser.
• CO2 absorption: Hydrated Lime is used extensively to naturally absorb CO2 from the atmosphere, ideal for use in cool stores where fruit benefit from a CO2 reduced environment.
• Tanning industry: Hydrated lime is added to the process to soften the pelt and to maintain the correct PH levels. It is also widely used to treat any waste by products from the tanning process.
• Herbicide development: Hydrated Lime widely used to produce a number of herbicidal products
• Pulp and paper: Hydrated Lime assist in the bleaching process.
