HOW TO USE GUIDE

*use only for scientific projects or research for now
Introducing CrackHeal – the revolutionary bio-concrete additive powered by Bacillus subtilis to repair cracks, extend concrete lifespan, and slash maintenance costs. Autonomously. Sustainably.

CrackHeal is a scientifically engineered, spore-based microbial additive for concrete. When mixed into fresh concrete, our proprietary Bacillus subtilis strains lie dormant until water enters new micro-cracks. They then activate, producing limestone that permanently seals cracks up to 0.8mm wide — preventing corrosion, reinforcing structural integrity, and making concrete truly self-healing.

Key Features & Benefits:

Bio-Healing Technology

• Contains robust Bacillus subtilis spores specifically selected for extreme alkaline and dry conditions.

• Spores remain viable for decades until activated by moisture and air.

Seamless Integration

• Easy-to-use powder or liquid formulation.

• Simply blend during concrete batching — no special equipment or labor required.

Extends Concrete Lifespan by up to 30%

• Reduces water and chloride penetration.

• Prevents steel rebar corrosion.

• Lowers lifecycle costs and maintenance frequency.

Eco-Friendly & Sustainable

• Non-toxic, non-pathogenic, and safe for workers and the environment.

• Reduces CO₂ footprint by cutting concrete replacement needs.

Proven Performance

• Laboratory and field-tested under various environmental conditions.

• Self-heals cracks repeatedly over the structure’s lifespan.

Ideal For:

• Civil and structural engineers

• Infrastructure projects (bridges, tunnels, roads)

• Industrial flooring and basements

• Water-retaining structures (dams, reservoirs, sewers)

• Precast concrete manufacturers

• Sustainable construction projects aiming for LEED certification

How It Works (Simple Steps):

1. Mix – Add CrackHeal during concrete batching as per dosage guidelines.

2. Set – Concrete sets normally; bacterial spores remain dormant inside.

3. Activate – When cracks form and water seeps in, spores germinate.

4. Heal – Bacteria metabolize nutrients to produce calcium carbonate (limestone), sealing cracks completely.
