Resin capsule or cartridge?

24. September 2019

Installing heavy loads is part of everyday life on the construction site, during which safety plays an important role. Resin capsules are a popular option. They are the tried and tested solution in various concrete applications for transferring high loads into concrete free of expansion. Or might a cartridge be the better solution? Stefan knows the answer.

We will examine whether a resin capsule or a cartridge is better suited for the construction site by looking at the example of the injection mortar system. Both products are intended to fix high loads in cracked and non-cracked concrete. They also both have a European Technical Assessment Option 1 for cracked concrete and a Swiss Shock Approval.

everyday life on the construction site: Resin capsules are a popular option.

Save time and costs with the glass resin capsule

The issue of safety soon arises when using glass products on a construction site. Isn’t it dangerous having glass on a building site? First off, it’s good to know that the glass capsules were designed specifically for life on the construction site. Nevertheless, treating them with care won’t do any harm. A glass capsule offers several advantages on the building site, as the fact that the capsule is enclosed in glass makes it an economic solution. This means you avoid injecting too much mortar into the drill hole because the enclosed capsule provides the designated quantity of mortar. This is particularly advantageous for professionals who use multiple fixing solutions every day. If you use slightly too much mortar on every drill hole it quickly adds up to a lot of wasted product at the end of the day. This is not the case when it comes to the resin capsule.

Whether you opt for the cartridge or the resin capsule is up to you. Both products provide the same load levels.

Cleaning the drill hole no longer required with resin capsule

Another advantage is that there is no need to clean the drill hole when using a capsule. You can find out here why cleaning the drill hole is usually so important. When using a capsule there is no need for this step thanks to the glass. Once the capsule is placed in the drill hole and the anchor is inserted with a rotary hammering motion the glass is pulverised. The pulverised glass inside the borehole scratches the walls of the drill hole, thereby milling small grooves into the hole. The mortar then grips into these serrations so that the drill hole cleans itself.

An overview of the cartridge

The fischer injection mortar can be used to install railings, machines and steel constructions both indoors and outdoors, for instance. The advantage of the cartridge: both the long and short versions are suitable for prepositioned and push-through installation. The cartridge also enables annular gap filling. Those who are unsure which product to use when processing chemical systems should preferably opt for the cartridge. It has a slightly longer hardening time and can therefore be readjusted, which is not possible with the capsule. If the drill hole isn’t quite right then the cartridge is your perfect choice, as the drill hole doesn’t have to have a precise depth when it comes to this product. It could also be set deeper if the clamp length is too long compared to the attachment part, for instance.

Overhead applications with a cartridge

A cartridge can be installed without a hammer drill, which is particularly useful for overhead installation. If you are working within a small space, then installations using a drill hammer can become difficult. Bear in mind when using a cartridge that the drill hole requires cleaning (blow twice, brush twice, blow twice). A hollow drill is a time-saving alternative that enables the simultaneous drilling and cleaning of the drill hole in just one step. The injection mortar FIS HB offers the highest load values in cracked concrete, which requires fewer fixing points. This saves time and cost and makes it ideal for serial installation.
