How to calculate the amount of resin you need?

4 min

What you gain in the first place by estimating the optimum amount of resin is reduced costs, since you can buy exactly as many packs of bonded anchor as you need at a given time.

The Rawlplug Calculator is an intuitive tool making it possible to quickly verify how much resin you need for a specific job. Check how our free-of-charge calculator works and how you can make your job much simpler.

Matching the amount of resin needed to a specific type of installation work not only saves money (you buy exactly as many packs of bonded anchor as you require); it also helps you save the environment, since you don’t need to worry about what to do with the leftover resin and how to dispose of it. Keep in mind that, unlike mechanical fixings, bonded anchors have an expiry date past which they should not be used. For this reason, making your stock of resin too large is not advisable, especially if you are not sure you will be able to consume it all.

Resin calculator from Rawlplug – why is it worth your while?

The resin consumption calculator is available to all EasyFix users. However, if you don’t use our app and still want to calculate the resin amount you need, you can visit our website to run the necessary calculations quickly and conveniently.

Perform design calculations faster and more comfortably

In order to better match the fixing type to the installation job at hand, use our proprietary EasyFix program. This tool will also instruct you on the optimum anchorage depth, should you decide to use resin. Knowing this, you can accurately calculate the amount of chemicals needed for a chosen kind of construction work.

How to use the Rawlplug Resin Calculator? Step-by-step instructions

  1. Navigate to The calculator is available in several language versions. Should you prefer to use the calculator directly on your computer, download the EasyFix software. The calculator is one of the program modules.
  2. Select the fixing and substrate type. The calculator allows you to perform calculations for: threaded rods installed in solid and hollow substrates, rebars installed in solid substratesinternally threaded sockets, bridge deck overhang anchors.
  3. Select the resin type you intend to use.
  4. Choose the packaging size and thread diameter. The diameter of the hole in the substrate and the anchorage depth will be adjusted automatically. 
  5. Enter the intended number of fixings. 
  6. The program will automatically calculate the leftover resin, i.e. the amount of resin that will not go into the holes. This is a value you can modify yourself. The leftover resin amount is often defined by installers based on their experience or depending on the dispensing equipment at hand (manual or automatic).
  7. Once you have clicked the Summary button, you will be provided with the necessary information, such as the total amount of resin needed, the amount of resin per fixing, the number of fixings you can complete using one packaging unit, and the required number of packs.
