ASR Concrete Protection | Stop Alkali-Silica Reaction & Strengthen Structures

The Problem: Alkali-Silica Reaction (ASR) & Structural Weakening

Alkali-Silica Reaction (ASR) causes expansion, cracking, and loss of strength in concrete, leading to surface deterioration, increased porosity, and reduced load-bearing capacity. Moisture accelerates ASR, making structures more vulnerable to long-term damage.

The Solution: Surtreat’s ASR Mitigation & Concrete Strengthening System

Surtreat provides a multi-step system to inhibit ASR, strengthen concrete, and prevent further deterioration:

TPS XVII: ASR inhibitor that neutralizes expansive reactions and prevents new ASR formation.
TPS XVIII: Lithium silicate densifier that strengthens concrete and seals micro-cracks.
SurCoat: Cementitious repair system that restores surface integrity and prevents moisture ingress.
Repel WB: Silane/siloxane water repellent that creates a hydrophobic barrier against future moisture damage.

Application Process: How to Treat & Prevent ASR Damage

Step 1: Surface Cleaning
- Remove debris, dirt, and coatings to allow penetration of treatment.
- Ensure exposed rebar is free of corrosion for optimal bonding.

Step 2: Apply TPS XVII
- Apply TPS XVII to neutralize ASR expansion and halt future chemical reactions.
- Ensures lithium ion concentration reaches the cement phase.

Step 3: Apply TPS XVIII
- Apply TPS XVIII to strengthen the concrete matrix, seal cracks, and reduce porosity.
- Improves durability, reducing the likelihood of future ASR-related damage.

Step 4: Repair with SurCoat
- Use SurCoat to seal larger cracks and restore surface integrity.
- Forms a durable, moisture-resistant finish to protect against environmental exposure.

Step 5: Apply Repel WB
- Final application of Repel WB creates a hydrophobic barrier against moisture infiltration.
- Reduces freeze-thaw damage and minimizes future maintenance needs.

Results: Why Surtreat’s ASR Protection System Works

✅ Neutralized ASR Expansion – Stops ongoing ASR reaction, preventing further damage.
✅ Strengthened Concrete – TPS XVIII increases compressive strength and durability.
✅ Sealed & Repaired Cracks – SurCoat restores surface integrity and prevents moisture infiltration.
✅ Superior Moisture Protection – Repel WB creates a long-lasting hydrophobic barrier.
✅ Cost-Effective ASR Mitigation – Reduces the need for costly demolition and reconstruction.
