Injection mortar

Injection mortar (also known as Chemical anchor or grout for anchor rods) is THE solution when you need very strong fastening in concrete or masonry, without expansion pressure on the base material. This makes it ideal for both heavy structural applications and situations where you need to work close to edges or with limited centre-to-centre distances.

Injection mortar (chemical anchor) for strong and reliable anchoring

Injection mortar (also known as Chemical anchor or grout for anchor rods) is THE solution when you need very strong fastening in concrete or masonry, without expansion pressure on the base material. This makes it ideal for both heavy structural applications and situations where you need to work close to edges or with limited centre-to-centre distances.

An injection system operates with two components which are mixed in mixing nozzles and then injected into the borehole. You then screw in an anchor rod, threaded rod or rebar – creating a powerful bond.

What injection mortar do you need?

Within the range of injection mortars, you'll find different resin types, each with its own application area:

  • Polyester injection mortar: This system is suitable for medium loads and can be used in uncracked concrete and both hollow and solid stone. Polyester is an affordable solution for standard anchorings in construction.

  • Vinylester: This system is suitable for heavier loads and can be used in both cracked and uncracked concrete. Vinylester provides strong adhesion and is extremely durable.

  • Hybrid injection mortar: For extremely heavy loads and fast curing, our hybrid system is the best choice. It can be used in cracked and uncracked concrete and combines the advantages of different resins for optimal performance.

  • Pure epoxy injection mortar: This system is ideal for the most demanding situations, where extreme strength and slow curing are required. Pure-Epoxy is ideal for use in cracked and uncracked concrete under very heavy loads.

Are you working in cracked concrete or met seismic loading?Then choose a mortar with the right ETA/approval class for your application.

Drill hole preparation: determining the final strength

The ultimate tensile strength depends on the drill hole preparation. That's why at B+BTec you'll also find all the tools to do it right:

  • sleeves, extensions and nozzles

  • dispensers/cartridge holders

  • steel brushes, blow-out pumps and (where necessary) eesh sleeves for hollow brick

  • tools for specific drill holes (e.g. diamond drilled holes)

Need help choosing the right mortar?

Unsure if you need polyester, vinylester, hybrid, or epoxy – or which ETA requirement applies to your project? Choose your substrate (concrete/stone), load, thread diameter and hole conditions, and then select the appropriate injection mortar and accessories. If you can't figure it out, get in touch and we'll help you make a safe and practical choice.
