Concrete Curing Blankets

High-Performance Wet Curing Blankets for Concrete Hydration Control

Proper curing is essential to achieving specified concrete strength, surface durability, and long-term performance. Inadequate moisture retention during the curing phase can lead to:

• Plastic shrinkage cracking

• Surface dusting

• Reduced compressive strength

• Poor abrasion resistance

• Increased permeability

GeoCHEM GeoKure Wet Curing Blankets are engineered to maintain continuous surface hydration, minimizing moisture loss and promoting proper cementitious hydration across the entire slab or structural element.

Why Wet Curing Matters

Concrete strength development depends on sustained moisture availability during hydration. Rapid evaporation—particularly in hot, dry, or windy conditions—can significantly reduce ultimate strength and compromise surface integrity.

Wet curing blankets help:

• Maintain consistent surface moisture

• Reduce early-age cracking

• Improve density and durability

• Enhance abrasion resistance

• Improve long-term freeze-thaw performance

For structural pours, bridge decks, pavements, and industrial slabs, proper curing is not optional—it is performance-critical.

Compliance with Industry Standards

GeoKure Wet Curing Blankets meet and exceed the requirements of:

• ASTM C171 – Standard Specification for Sheet Materials for Curing Concrete

• AASHTO M171 – Standard Specification for Sheet Materials for Curing Concrete

These standards address moisture retention capability, reflectivity, durability, and performance under field conditions—making GeoKure suitable for DOT and commercial specifications.

Product Features & Benefits

• Lightweight and easy to deploy

• Disposable for labor efficiency

• Excellent moisture retention properties

• Durable poly backing to reduce evaporation

• Uniform coverage across large slab areas

• Available in convenient 9’ x 250’ rolls

The combination of absorbent core material and moisture-resistant backing creates an effective wet curing system that limits evaporation while maintaining surface hydration.

Applications

GeoKure Wet Curing Blankets are ideal for:

• Highway and roadway paving

• Bridge decks

• Airport runways

• Industrial floor slabs

• Commercial flatwork

• Parking structures

• Tilt-up panels

• Sidewalks and municipal infrastructure

They are particularly valuable in high-temperature or low-humidity environments where evaporation rates are elevated.

Installation Best Practices

For optimal curing performance:

1. Apply blankets immediately after finishing operations when surface bleed water has dissipated.

2. Pre-soak blankets prior to placement for maximum moisture availability.

3. Ensure full surface contact with minimal air gaps.

4. Overlap adjacent blankets to prevent edge drying.

5. Maintain moisture levels throughout the curing duration as specified by project requirements.

Proper installation ensures uniform hydration and reduces the risk of surface defects.

Advantages Over Alternative Curing Methods

Compared to curing compounds, wet curing blankets provide:

• Continuous hydration rather than surface sealing only

• No need for chemical application

• No interference with bonding of future coatings or toppings

• Improved curing in windy conditions

• Reduced risk of uneven coverage

For projects requiring maximum durability and structural performance, wet curing remains one of the most effective curing methods available.

Economic & Performance Impact

Inadequate curing can reduce compressive strength and increase long-term maintenance costs. Investing in compliant wet curing blankets:

• Protects specified PSI targets

• Improves durability lifecycle

• Reduces call-backs and surface repairs

• Supports compliance with DOT and engineered specifications

Given the relatively small material cost compared to total concrete placement costs, proper curing represents a high-return investment.
