How to calculate the amount of resin you need?

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.

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. The calculator is available for free; you don’t even need to create a user account or provide your personal details to use it. We deliver this tool to our customers as a part of our comprehensive support and technical assistance.

1. Navigate to https://calculator.rawlplug.com/#/en/. 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 substrates, internally 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.

Chemical anchors provide a good alternative to mechanical fixings, especially if high-strength joints is what you need. The key advantages of bonded anchors include:

• Capacity to carry the highest loads – this is attributable to the way bonded anchors bond to the substrate. Resin is evenly distributed over the entire depth of the hole, which enables it to form an almost uniform structure with the substrate, additionally reinforcing it.
• Wide range of applications – bonded anchors can substitute for any type of mechanical anchor. They also manage well wherever traditional anchors cannot be used, providing both durable and secure fixing whenever you are uncertain of the substrate condition.
• Anchoring possible in a variety of substrates (including flooded holes, areas prone to vibration, and seismic zones).
• Densely spaced anchoring points, if needed, both against one another and close to edges – this feature makes bonded anchors clearly distinguishable from mechanical anchors. The latter must be fixed at much greater distances both from individual anchoring points and from edges. Smaller distances between anchoring points allow smaller base plates to be used, which often translates into improved visual qualities and lower construction costs.
• Deep anchoring (up to 2.5 m) capability, unique to this type of fixings.
