If you are looking for a reliable fastening solution for transferring extreme loads to surfaces such as concrete, cement or masonry, chemical anchors, commonly known as chemical dowels, are an ideal choice.
We at RESIMIX study and implement these solutions intended for various projects, including the Genoa Metro, where we used our RESICOL 110 pourable chemical anchor for fixing the rails.
What are chemical anchors?
Chemical anchors are an advanced technique for fastening to concrete and similar substrates, offering greater flexibility than traditional mechanical anchors. Unlike mechanical anchors that can compromise the structure, chemical anchors use a chemical resin injected into a hole, followed by the insertion of a threaded rod. This solution offers greater durability, heat resistance and superior anchoring properties.

The advantages of using chemical dowels.
- Long life: chemical resin anchors are designed to stand the test of time, ensuring exceptional durability.
- Heat resistance: they are also ideal in extreme conditions, with very high or particularly low temperatures.
- Superior anchoring properties: chemical anchors offer higher stability than mechanical anchors.
- Chemical resistance: these anchors maintain their integrity even in the presence of chemicals.

How do chemical anchors work?
The chemical anchor technique involves injecting resin into the hole before inserting the threaded bar, creating an air seal and making the hole watertight. Unlike mechanical anchors, chemical anchors allow virtually unlimited embedment depth, allowing the insertion of bars of any length to increase load capacity.
What are the technical advantages of chemical anchors?
- Unlimited built-in depth: the ability to adjust the depth increases the loading capacity.
- Uniform load distribution: chemical anchors eliminate stress caused to substrates during tightening by distributing the load evenly.
- Large fastening area: due to the resin flowing into the hole, a larger surface area is obtained, which strengthens the fastening area.
Chemical anchors are an advanced and reliable fastening solution, offering a safe and versatile alternative to traditional mechanical anchors. By following proper procedure, you will benefit from long life, heat resistance and superior anchoring properties for your projects.
