Resin Anchor Polyester CE7 Certified – Chemical Anchoring System

Resin Anchor Polyester CE7 Certified is a two-component,
styrene-free polyester resin anchoring system designed for
medium to heavy-duty fixings in concrete, brick and masonry.
CE7 / Option 7 classification (see ETA/CE documentation) makes it suitable for
non-cracked concrete and masonry applications such as
threaded rod, studs and rebar anchoring in a wide range of
construction, structural and installation projects.

Resin Anchor Polyester CE7 Certified is supplied in a
coaxial or side-by-side cartridge containing resin and hardener that
are mixed automatically in a static mixer nozzle during application. Once dispensed into a
properly cleaned drill hole, the resin cures to form a
high-strength bond between the anchor (threaded rod or rebar) and the base material.

Typical suitable applications include:

• Anchor rods and studs (e.g. M8–M16 and above – confirm with ETA) in
  non-cracked concrete and masonry,
• Starter bars / rebar dowels in concrete (where permitted by the ETA and local design codes),
• Fixing structural and secondary steelwork to concrete or masonry supports,
• Medium-heavy plant, machinery and bracket fixings,
• Handrails, balustrades, canopies and frames anchored into concrete or brickwork.

Polyester resin anchors are widely used due to their:

• Good all-round performance in a broad range of substrates,
• Fast curing times (depending on temperature), and
• Cost-effective solution for many general construction anchoring tasks.

Typical Use Cases

• Structural & secondary steel – anchoring baseplates, columns, brackets and cleats to concrete slabs and walls.
• Mechanical & electrical supports – fixing pipe racks, cable trays, containment and plant frames to concrete and masonry.
• Handrails & balustrades – securing posts and rails to stairs, balconies and slabs.
• Timber & façade subframes – anchoring timber or metal ledgers and battens to masonry substrates.
• Rebar dowelling – installing starter bars and connection bars in concrete (within ETA scope and structural design).

Installation & Application Instructions

1. Substrate & Design Checks

• Confirm the base material (e.g. non-cracked concrete, solid brick, hollow block) is
  covered by the CE7 / ETA approval for this product.
• Design the anchors in accordance with Eurocode 2 / EN 1992-4 or relevant national standards and the
  product ETA/load tables.
• Verify hole diameters, embedment depths, edge and spacing distances for the chosen
  anchor size (M8, M10, M12, M16, etc.).

2. Drilling the Hole

• Use the specified drill bit diameter and drill to the required embedment depth (plus allowance for dust).
• Drill in rotary or rotary hammer mode as appropriate for the substrate.
• Maintain correct edge distance and anchor spacing as per design and ETA.

3. Hole Cleaning (Critical Step)

• Thoroughly clean the drill hole following a blow–brush–blow sequence:
  1. Blow out dust with an appropriate blow pump or oil-free compressed air,
  2. Brush the hole with a suitably sized steel/nylon hole brush,
  3. Blow out again to remove all remaining dust and debris.
• Repeat until the hole is visibly clean; poor cleaning significantly reduces bond strength.

4. Preparing the Cartridge

• Check the expiry date and storage conditions on the cartridge.
• Insert the cartridge into a suitable application gun (many are usable with a standard mastic gun – check packaging).
• Attach the static mixing nozzle supplied; do not modify or shorten the nozzle.
• Dispense a small amount of resin (until colour is uniform) to waste to ensure correct mixing.

5. Injecting the Resin

• Starting from the bottom of the hole, inject resin while slowly withdrawing the nozzle to avoid air pockets.
• Fill the hole to approximately 2/3 full for solid materials (or as specified in the instructions).
• In hollow blocks, use perforated sleeves to contain the resin and anchor (where permitted by ETA).

6. Installing the Anchor

• Insert the threaded rod or rebar using a slow twisting motion to ensure full wetting of the surface.
• Do not disturb or load the anchor during the gel/curing time.
• Ensure the anchor is installed to the correct embedment depth and remains straight.

7. Curing Time

• Allow the resin to cure for the minimum time specified on the cartridge / datasheet,
  which depends on substrate temperature (colder = longer).
• Do not apply load or torque until full cure has been achieved.

8. Tightening & Loading

• Once cured, fit the washer and nut and tighten to the specified torque (if required by design/ETA).
• Apply service loads only after curing and tightening are complete.

Frequently Asked Questions – Resin Anchor Polyester CE7 Certified

1. What does CE7 / Option 7 mean?

CE7 / Option 7 generally refers to an ETA classification for bonded anchors used in
non-cracked concrete. It defines:

• The base materials in which the anchor can be used,
• The anchor types and sizes covered, and
• The design values and partial safety factors to be used for structural design in accordance with EN 1992-4.

Always check the product’s ETA and Declaration of Performance for the exact scope of approval.

2. Can I use this resin in cracked concrete?

Polyester CE7 / Option 7 systems are typically approved only for non-cracked concrete.
For cracked concrete or seismic applications, a different resin system with a suitable ETA
(e.g. hybrid or epoxy with cracked-concrete approval) is normally required.

3. Can I use this product in hollow block?

In many cases, yes, when used with appropriate perforated sleeves and within the
ETA’s masonry approval scope. You must:

• Check that hollow masonry is covered by the product’s ETA, and
• Follow the manufacturer’s instructions for sleeves and installation.

4. How long must I wait before loading the anchors?

Curing time depends on temperature and resin formulation. As a guide:

• At warmer temperatures, the resin cures faster (shorter waiting times),
• At colder temperatures, allow significantly longer cure times.

Always follow the temperature vs. curing time table on the cartridge/technical data sheet and
never load the anchors before full cure.

5. Can I reuse a partially used cartridge?

Yes, typically you can:

• Leave the mixing nozzle attached to act as a temporary cap, or
• Fit a new nozzle when reusing, discarding the old one.

Ensure:

• The resin is within its shelf life,
• The cartridge has been stored according to manufacturer recommendations.
