Waterproof concrete, directly from the concrete plant

Basilisk Self-Healing Concrete is a waterproof concrete based on crack filling micro-organisms

  • Waterproof concrete for water retaining structures

  • Less repairs, longer service life

  • Save up to 40% shrinkage reinforcement due to waterproof properties

1. Waterproof concrete

Basilisk Self-Healing Concrete seals cracks in concrete waterproof. This creates waterproof concrete, a coating or waterproof membrane is no longer necessary. No additional actions or materials are required to make the self-healing concrete waterproof. Waterproofing simply becomes a property of self-healing concrete when Basilisk Healing Agent is added to the concrete mix, already at the concrete plant.

2. Less repairs with waterproof concrete

Concrete with ‘Basilisk Healing Agent’ is waterproof and ensures autonomous crack repair, eliminating unforeseen costs and time-consuming injection work. When a crack develops, it heals itself. Without human intervention! This means waterproof concrete saves you money on maintenance costs.

3. Reducing shrinkage reinforcment with waterproof concrete

Self-healing concrete is waterproof and due to these waterproof properties, you can save up to approximately 40% on shrinkage reinforcement. In this project case we explain how this works and what advantages are. If you want to save shrinkage reinforcement by using self-healing, waterproof concrete, this can easily be done, without deviating from the current standards or regulations.

This is how self-healing waterproof concrete works

Waterproof concrete infographic

1. Concrete cracks

Cracking is an accepted and common phenomenon in concrete structures.

2. Leakage & corrosion

However, cracked concrete may result in serious leakage and reinforcement corrosion issues.

3. Autonomous repair

When in contact with water, the bacteria will multiply and starts to produce limestone, making the concrete waterproof again.

4. Cracks are sealed

Due to the formation of limestone, cracks are autonomously repaired, preventing leakage and protecting the reinforcement.

Applications of self-healing waterproof concrete

Watertight self-healing concrete has the greatest added value in constructions where the watertightness of concrete is important. Such as concrete structures where seawater or groundwater often causes problems. Below are a number of examples of application with waterproof concrete.

Tunnels & Bridges

Basements & Diaphragm walls

Liquid-containing reservoirs

Flooring & Parking decks

Waste water treatment plants

Marine, Harbors & Airports

“Normally I would now have to call in a repair injection crew. Thanks to the Self-Healing capacity of the concrete, this is no longer necessary”
Projectmanager, Evides waterbedrijf


Watertanks at Evides with waterproof concrete from Basilisk

As part of the expansion project of a wastewater treatment plant in The Netherland, the new tanks were executed with Self-Healing Concrete. Shortly after installation, the first shrinkage cracks and therewith leakages appeared.

After a short period of about 10 weeks, the cracks are sealed and waterproof. Completely in line with waterproofing requirements, and without additional repair works such as injection.
