What is Chemical Anchoring?
Chemical anchoring is a method for fastening to concrete (or similar substrates), this technique provides more flexibility than the more popular mechanical anchoring.
Advantages of Chemical Anchoring
The Chemical Anchoring technique uses a resin that is injected into the hole before the insertion of the stud, which offers the following benefits:
- The hole is airtight and waterproof
- The chemical naturally fills in all irregularities which allows for 100% adhesion
- Virtually unlimited embedment depth
- Unlike mechanical anchors Chemical anchors allow you to embed any length of rod into the hole to increase load capacity* (e.g., if you choose to use a larger diameter hole with a thicker rod you can increase the load capacity)
Chemical Anchoring Products and Applications
We offer a wide range of Chemical Anchoring products to suit any application, our product offering includes Ramset’s Chemset 101 and a full array of ICCONS products:
Ramset Chemset 101
Chemset 101 is a multi-purpose polyester mortar for anchoring studs with threaded rod and starter bars in solid and hollow substrates. This chemical anchoring product from Ramset has been formulated using high performance, marine grade resin, which allows full load capacity in flooded holes to be attained.
ICCONS
ICCONS range of chemical adhesive anchoring solutions include Pure Epoxy, Hybrid, Vinylester and Polyester injection systems for performance applications in cracked and non-cracked concrete. Ideal for fixing rebar, threaded studs, internally threaded sockets and threaded rod. Fasten structural steel connections, balustrades, façades or use in other residential, commercial and civil applications. Products are National Code Compliant, while some are approved for Cracked Concrete, C1 / C2 Seismic applications, Dustless Drilling or Fire Rated.
When choosing a Chemical anchoring product, consider the application and the requirements specified by your engineer:

When anchoring is installed in high loading and critical situations, the use of chemical anchoring - also known as chemical injection - is essential.
Threaded rod or rebar is often used, and it is recommended you use a high-quality adhesive to create an airtight bond between the stud and masonry. This ensures that the bar, stud rebar or threaded rod grips the sides of the drilled hole with no pockets of space between irregular features such as the thread or mechanisms.
And it's not just the right products you need. Certification is also essential, so your project's results are compliant to building-related standards. Chemical studs/anchoring systems from NHS are available with complete data and certifications from the manufacturer, so you can tick all the compliance boxes, pre and post- installation.
