Basilisk Self-Healing Repair Mortar MR3
With Basilisk Self-Healing Repair Mortar MR3 you can easily repair damaged concrete covers, cracks and remedy water leaks in existing concrete structures.
Traditional repair methods often fail and have to be repeated over time due to their limited deformation capacity and compatibility with the original concrete. With Basilisk MR3, deformations can be resolved inside the repair mortar.
Benefits of Basilisk MR3 for Concrete Repair
Self-Healing Properties
Integrated autonomous crack healing capability provides a durable repair. Water leakage is prevented and chances of corrosion of the reinforcement are significantly reduced.
High Deformation Capacity
Ductile behavior allows durable repair of cracked concrete surfaces or brick mortar walls subjected to overloading such as mild earthquakes or dynamic loading conditions.
Strong Bonding
Fine-meshed crack-controlled behavior with strong bonding. Contains PVA fibers to ensure high flexural capacity, allowing the hardened mortar to shrink and expand with the original concrete.
Watertight Repair
Prevents debonding and brittle failure when subjected to high load stress. Residual cracks are self-healed, ensuring a watertight repair solution.
Durable Repair of Leaking Cracks
Traditional repair methods often fail and have to be repeated over time. With Basilisk MR3, deformations can be resolved inside the repair mortar for lasting results.
Easy to Process
Ready-mix repair mortar that can be applied manually or as shotcrete mortar, making it suitable for smaller patch repairs as well as larger surface area repairs.
Applications & Opportunities
Basilisk MR3 is suitable for any technical concrete repair across a wide range of infrastructure.

Basilisk Repair Mortar MR3 — Step by Step
- 1Prepare and saturate the substrate; expose sound concrete
- 2Mix MR3 with 3.8–4.2 L of water per 15 kg bag
- 3Apply manually or spray as shotcrete in lifts up to 40 mm
- 4Cure normally — residual shrinkage cracks self-heal over time
Straight from Basilisk
With Basilisk Self-Healing Repair Mortar MR3 you can easily repair damaged concrete covers, cracks and remedy water leaks in existing concrete structures. Traditional repair methods often fail and have to be repeated over time due to their limited deformation capacity and compatibility with the original concrete. With Basilisk MR3, deformations can be resolved inside the repair mortar — its ductile behavior with PVA fibers prevents debonding and brittle failure, and residual cracks self-heal with limestone to ensure a watertight repair.

When to Specify Basilisk Repair Mortar MR3
Use this guide to match the right product to your structure, exposure, and crack profile.
Best fit when
- •Patch repairs of damaged concrete covers
- •Spalled rebar zones and corrosion-driven delamination
- •Surfaces subject to dynamic loading, mild seismic, or thermal cycling
- •Watertight repairs where leakage and corrosion risk must be reduced
- •Manual application or shotcrete on bridges, decks, and marine structures
Consider another product when
- •Hairline shrinkage cracks (≤0.8 mm) with no spalling — use ER7 liquid
- •New pours — specify Healing Agent in the mix design instead
- •Layers thicker than 40 mm in a single pass (build up in lifts)
Situation-by-Situation Recommendations
Bridge deck & soffit patching
Use MR3 to rebuild concrete cover over corroded rebar. Its 36.7 MPa compressive strength and ≥1.5 MPa bond meet EN 1504-3 R3 for structural repair.
Parking garage spall repair
Ideal for high-traffic decks subject to freeze/thaw and chloride exposure — self-healing residual cracks keep the patch watertight long-term.
Water-retaining tanks & reservoirs
Apply MR3 to seal leaking cracks and rebuild damaged liner concrete. Self-healing properties continue protecting after the repair sets.
Tunnels & diaphragm walls
Spray-apply as shotcrete for large surface areas. High ductility absorbs ongoing structural movement without brittle failure.
Marine structures & harbor walls
Use to repair tidal-zone spalling and chloride-driven damage; the watertight, self-healing matrix protects new and existing reinforcement.
Historic / heritage concrete
Strong bonding plus fine-meshed crack control allows the hardened mortar to shrink and expand with the original substrate — limiting visible patch lines.
Proven Performance & Durability
Basilisk MR3 is designed for durable, long-lasting concrete repair — here's what the data supports.
Tested at 28 days per EN 1504-3 Class R3, ensuring structural integrity for demanding repair applications.
Self-healing properties seal residual cracks, reducing water leakage and protecting reinforcement against corrosion over time.
Unlike traditional repair methods that often fail and must be repeated, MR3's ductile behavior and self-healing capability provide a lasting solution. No specific years-added number is published for MR3.
