Roadware Metric Product Estimator

Use this on-line estimator to determine the amount of Roadware 10 Minute Concrete Mender™or other Roadware products needed to make your repair. The estimator program is based on mathematical calculations and will give a rough estimate in 300x300ml cartridges or liters needed to repair a crack or spall.



Sand: One liter of 40-30 medium silica sand weights about 1.6kg. If you use one liter of Concrete Mender with a 2 to 1 sand ratio. you will need 2 liters of sand or 3.2kg.
