Injection Resin & Capsules

High‑Strength Chemical Anchoring for Structural Fixings

Injection resins and glass capsules provide a dependable solution for anchoring threaded studs, rods, and fixings into concrete, masonry, and dense natural stone. At Electro South West Ltd, we supply a wide range of resin systems including epoxy, vinylester, and polyester formulations, along with spin‑in and hammer‑in glass capsules designed for fast, controlled installation. These systems are widely used for structural fixings, rebar connections, heavy machinery anchoring, and high‑load applications where mechanical anchors alone may not offer sufficient performance.

Choosing between injection resin and capsules depends on the job: cartridges offer flexibility for multiple fixings, while pre‑portioned capsules provide clean, consistent anchoring especially useful for overhead or single‑point installations. Many installers pair these anchoring systems with Resin Studs and Drill Bits to ensure correct hole preparation, installation, and curing performance across a range of site conditions.

Frequently Asked Questions

When should I use resin capsules instead of injection resin?

Capsules are ideal for single fixings, overhead work, or situations where consistent resin volume is critical. They provide a clean, pre‑measured solution and are commonly used with threaded studs in concrete or dense stone.

What substrates are suitable for chemical anchors?

Most injection resins and capsules are designed for concrete (cracked or non‑cracked), masonry, and dense natural stone. Always check the resin type—epoxy and vinylester typically offer the highest load capacity and chemical resistance.

Do I need to clean the hole before using resin?

Injection resins usually require thorough hole cleaning for maximum bond strength. Always follow the product’s installation guidance.
