Neutralization is the process whereby acids and alkalis (wastes) can be rendered harmless. Limestone (marble) chips or lumps are used in numerous applications to help neutralize and/or dilute chemical bearing wastes (e.g. acid wastes). After years of successful neutralization and dilution, many state and environmental plumbing codes call for the addition of limestone chips into acid neutralization basins, tanks, or sumps. Water is also added to the tanks to initiate the dilution process. The limestone chips we offer exceed application requirements. The following two requirements are vital to proper limestone performance: The limestone must be in the one to three inch (1” – 3”) diameter size range and must contain a high calcium carbonate content in excess of 90%. Our limestone contains about 95%.

The use of our limestone and tanks is frequently the best and least expensive means to protect pipes and sewers from damage and to meet stringent environmental and plumbing codes.

Our Limestone Chips are sold in 50 lb. bags. Use the chart below to identify the amount of limestone needed.

* Water must be added to the tank first before adding limestone (see Maintenance Instructions).
* Special dolomitic limestone is available and required for wastes that are primarily concentrated     battery acids or sulfuric acid.
