Concremate Expanding Anchoring Cement
Anchor, patch and lock in place with confidence. Concremate is a high-performance expanding cement designed for rapid, reliable anchoring and structural patching. Mixed to a workable, mortar-like consistency, it expands slightly as it cures to counteract drying shrinkage. That controlled expansion grips embedded items and surrounding material tightly, delivering a secure, long-lasting hold that stands up to strain, stress and vibration.
Why choose Concremate
-
Fast turnaround: initial set in about 30 minutes and hard in approximately 1 hour, so many jobs can progress the same day.
-
Expands and grips: engineered expansion of about 0.125% offsets shrinkage and locks into the substrate.
-
High ultimate strength: cures to a finish that becomes harder than standard concrete at 28 days when properly mixed and applied.
-
Versatile application: ideal for anchoring bolts, rails, brackets and fixtures, as well as patching holes, chases and cracks.
-
Durable performance: forms a robust, long-term bond that resists severe mechanical stress and vibration.
Where it excels
Use Concremate for secure embedment and structural repairs on common mineral surfaces. It is suitable for:
- Concrete and masonry
- Brickwork and stone
- Tiles and terrazzo
- Plaster and similar mineral substrates
Typical projects
- Anchoring handrails, posts, machine base bolts, threaded rods and heavy brackets
- Fixing door and window hardware to masonry openings
- High-pressure grouting under plates, around pipe sleeves and service penetrations
- Patching voids, chased conduits, spalled edges and impact damage in floors, walls and ceilings
How it works
Concremate is a mineral-based expanding cement. After mixing with clean water, the paste hydrates and begins to set. A small, controlled expansion during cure offsets natural drying shrinkage. The result is a tight, interference-style fit that increases grip on embedded items and keys the patch into surrounding material. For best results, the material must be able to expand slightly while drying and should not be constrained in a completely sealed cavity.
Directions for use
-
Surface preparation: Remove dust, loose material, laitance, oil and contaminants. Roughen smooth surfaces and blow or brush clean. Pre-dampen porous substrates to a surface-saturated dry condition; do not leave standing water.
-
Mixing: Add powder to clean water while stirring until a smooth, lump-free, mortar-like consistency is reached. Mix only what you can place within the working time. Do not over-water.
-
Placement for anchoring: Fill the prepared hole or pocket from the bottom up to avoid entrapped air. Insert the fixture or fastener while the mix is workable and align immediately. Hold steady until initial set.
-
Placement for patching: Tightly pack the mix into the void in layers, compacting each layer to ensure full contact. Strike off and finish the surface as required.
-
Curing: Protect from rapid drying, wind and direct sun during early cure. Avoid vibration or load until the material has hardened.
-
Cleanup: Clean tools and splashes with water while product is fresh. Once hardened, mechanical removal may be required.
Good practice tips
- Plan the job so placement occurs immediately after mixing for best expansion and bond.
- For deep holes or large voids, place in lifts and compact each lift.
- Do not confine completely in a sealed cavity; allow space for controlled expansion.
- Avoid adding sand, cement or other admixtures that can change performance.
Performance and durability
When correctly mixed and applied, Concremate develops a hard, dense matrix with strong adhesion to mineral substrates and embedded metals. The slight expansion on cure reduces micro-gapping at the interface, improving load transfer and long-term durability. After full cure at 28 days, the set material achieves hardness that exceeds standard concrete, supporting demanding anchoring and patching tasks.
Safety and handling
- Wear suitable gloves, eye protection and a dust mask when mixing and placing.
- Avoid contact with skin and eyes. In case of contact, rinse with plenty of water.
- Store in a cool, dry place in the original, tightly closed container.
- Keep out of reach of children and pets.

What to expect on the job
With suitable surface preparation and correct mixing, you can expect a smooth placement, quick set and a dense, high-integrity bond. The expansion action helps lock hardware and patches into place. Protect new work from early movement and moisture loss, then return to service once the hard set has been achieved and the repair or anchorage has reached the necessary strength for your application.
Limitations
- Not for use where the mix cannot expand slightly during cure.
- Do not apply over active movement joints or flexible substrates.
- Working and set times vary with temperature, humidity and mix ratio.
Note: Always trial on a small, inconspicuous area or non-critical hole to confirm suitability for your specific substrate and conditions.
