CF850 & CF920

Chemical Anchoring - why and where?

Ceresit chemical anchors are two-component, quick-setting adhesives based on reactive resins.

They are designed to anchor steel studs, rods, bolts and anchorages into a different base material like concrete (cracked, non-cracked one, light concrete, porous concrete), solid masonry and hollow bricks or even natural stones.

The key importance of Ceresit chemical anchors is that they form very strong bonds, stronger than the base material itself. As a system is based on chemical adhesion, no load stress is imparted to the base material as in case of expansion type anchor.

Therefore they are ideal solution for high load applications, for close to edge fixing, reduced center or group anchoring and use in concrete of unknown quality or low compressive strength.

Ceresit chemical anchor products stand out on the market with excellent application abilities. Depending on exact product, fast-setting allows you to speed up work, while application in unfavorable conditions like low to high temperatures (even -10°C or +40°C) and demanding areas (flooded holes/ underwater anchors) make it a truly universal and reliable fixing solution.

The key benefits of Ceresit chemical anchoring range:

• High strength: since resin anchors are supposed to take the high load and safely distribute it to the base, Ceresit chemical anchors have minimum compressive strength of 88 MPa

• Tough, shrink-free bonding: once filling the gap between the anchor rod and the substrate, Ceresit chemical anchors produce a strong, tight & waterproof bonding, preventing water and aggressive substances from penetration and destruction of the rod and substrate

• Vibration and corrosion resistance: Ceresit chemical anchors provide a long life solution; they are chemically resistant in highly aggressive environments and thus protect anchor rod from corrosion too, they can also stand out vibrations due to wind or machine operations

• Can be placed in wet and damp conditions, even in underwater anchors

• For anchoring in variety of base materials/ substrates (incl those of low load-bearing capacity and cohesiveness)

• Free of expansion forces

• Perfect for problematic fixings like close axial or edge/ corner distance

• Universal in application areas and climatic conditions (indoors/ outdoors & downward, horizontal and upwards installation)

• Easy to install

Chemical Anchor is a long-lasting, strong and secure way to fix loads of various weights and problematic anchoring situations.

Types of application

Check where and which chemical anchor is most suitable!​

Light duty applications include many fixings for residential use (i.e. bathroom fixings, window shutters, satellite dishes, air conditioners and outside lights). Additional applications can include inside fixings such as televisions, overhead lighting fixtures andhanging cabinets.​

We recommend  CF850 for these types of light and medium load applications.

Chemical anchor is ideal in settings where external effects must be considered. Vibrations due to wind or machine operation can be overcome through the use of chemical anchor, which will securely retain the fixing element. Heavy duty fixings can include varied weigh loads where life and dead loads must be considered. This includes applications such as I-beams, balconies and railings.​

We recommend  CF850 or CF920 for these types of heavier duty applications.

In certain situations, chemical anchor is the only solution for fixing a load. Problematic applications include wet and underwater anchors where corrosion and aggressive environmental effects must be considered. Cracked concrete is another problematic application. Another challenging situation involves fixing a load with close axial or edge distance. Chemical Anchor will hold heavy loads that must be fixed close to the edge without creating any internal pressure. Post-installed rebar is an application that can only be completed using Chemical Anchor. For these types of applications the relevant choice is CF920.

Application on different substrates

There are many kinds of base materials. It is important to know their individual properties in order to determine the permitted load and to select suitable anchors. Only in this way is it possible to ensure that anchors are safe and of a high quality. Concrete, light building materials and masonry (including solid one and hollow brick) are the most commonly used building materials. Ceresit chemical anchors range is suitable for anchoring in all of them.
