If you’re a pool owner in Texas, especially in Austin, Liberty Hill, Cedar Park, or Georgetown, you might have heard about ASR cement issues—but what exactly does that mean? More importantly, how does it affect your pool?
As a pool renovation expert, I’ve seen firsthand how Alkali-Silica Reaction (ASR) can cause cracks, surface deterioration, and costly repairs in pool decks, coping, and plaster. If your pool is showing signs of cracking or premature wear, ASR-related cement problems might be to blame.
Let’s break down what ASR is, why it’s a big problem in Texas, and how you can protect your pool from costly damage.
What Is ASR (Alkali-Silica Reaction) in Cement?
ASR is a chemical reaction that occurs in concrete when:
1️⃣ The cement contains high-alkali materials
2️⃣ The aggregates (sand and gravel) contain reactive silica
3️⃣ There’s constant moisture exposure
Over time, these elements react, causing an expansive gel to form. This gel absorbs water and expands inside the concrete, leading to cracking, swelling, and surface deterioration.
Why Is ASR a Big Issue in Texas?
Texas is one of the worst states for ASR-related concrete issues due to:
🌡 Extreme Temperature Swings – Hot summers and sudden cold snaps accelerate cracking.
💧 High Humidity & Groundwater Levels – Moisture exposure fuels the ASR reaction, especially in pools.
🛠 Locally Sourced Aggregates – Many Texas concrete mixes contain reactive silica, making ASR more likely to occur.
For pool owners, this means:
✅ Plaster & pool deck cracking sooner than expected
✅ Surface roughness & premature wear on tile and coping
✅ Expensive resurfacing and structural repairs if left untreated
Signs of ASR Damage in Pools
If you notice any of these warning signs, your pool may have ASR-related concrete deterioration:
🔹 Spiderweb-like cracks in the plaster, deck, or coping
🔹 Surface discoloration or white deposits (from silica gel)
🔹 Cracks that keep returning despite previous repairs
🔹 Rough or pitted plaster that worsens over time
The earlier you catch ASR damage, the better your chances of preventing costly repairs.
How to Prevent & Fix ASR Damage in Your Pool
While ASR can’t be reversed, there are ways to slow it down, repair the damage, and prevent future issues.
1. Choose ASR-Resistant Pool Materials
✅ Use low-alkali cement for new pools or resurfacing
✅ Opt for ASR-resistant aggregates in your decking and coping
✅ Consider alternative materials like travertine or quartz finishes
2. Improve Waterproofing & Drainage
💧 Seal your deck & coping to reduce moisture penetration
💧 Ensure proper drainage to keep water away from pool surfaces
💧 Use water-resistant pool plaster that resists ASR-related expansion
3. Resurface with Modern ASR-Resistant Finishes
If your pool already has ASR-related cracking, resurfacing with a premium finish can prevent further deterioration. Popular ASR-resistant options include:
✔ Quartz-based plaster (durable & less reactive than standard plaster)
✔ PebbleTec & polished aggregates (less porous, longer lifespan)
✔ Advanced polymer coatings (moisture-resistant & highly durable)
4. Routine Maintenance & Professional Inspections
🔹 Regular pH balancing to prevent chemical-induced concrete stress
🔹 Annual pool surface inspections to catch minor cracks early
🔹 Sealant applications to protect vulnerable pool areas
