FAQs: Choosing and installing chemical anchors
What is the strongest anchor for fixing concrete?
A pure epoxy system is the best adhesive for concrete fixing and for seismic anchors. One of the strongest solutions is Epcon™ C8 Xtrem™ with high bonding performance for heavy loads, cracked concrete, seismic conditions, and extreme environments.
It is important to note that the strongest concrete anchor depends on the concrete strength, embedment depth, anchor diameter, edge distance, spacing and load type.
When should I use chemical anchors instead of mechanical anchors?
Chemical anchors are ideal for concrete repairs and non-invasive bonding of two materials without putting stress on the base material. It offers more versatility and reliability in both cracked and uncracked concrete environments and when structural reliability and high bearing loads are required. It is commonly used for bonding post-installed anchors with existing concrete structures.
When jobs require close-to-edge fixings, rebar anchoring or tight concrete anchor spacing, chemical anchoring handles it best without causing expansion pressure, which can lead to cracking.
Mechanical anchors may often be preferred for light to medium jobs that need immediate loading and no curing time.
Can chemical anchors be used in cracked concrete?
Yes. Epoxy anchors or vinyl ester chemical anchors can be used on concrete with existing cracks.
Epcon™ C8 Xtrem™ and ChemSet™ 801 XTREM™ XC² both maintain strength performance under tension or movement.
Make sure to follow proper hole cleaning and installation procedures when applying chemical anchors to cracks.
Are chemical anchors suitable for high-load applications?
Yes. Chemical anchors are commonly used for high-load concrete and bearing applications and are a dependable solution for heavy structural loads, such as steel connections to concrete footings, fixing beam base plates, machinery hold downs, rebar anchoring, safety barriers or tunnel service supports. It is common to use it where post-installed anchors are needed in existing concrete or masonry structures.
What is the difference between epoxy and vinyl ester anchors?
Epoxy anchors offer a high bond strength ideal for heavy structural loads, with a good working time, especially for deep embedment. Vinyl ester anchors generally cure faster than epoxy anchors and are versatile for various job site conditions. When fully certified, Vinyl ester can meet heavy-duty anchoring needs, such as concrete and seismic anchors, to offer a good balance of speed and performance.
