Driven From Many Levels
Low Volatile Organic Compound (VOC) regulations
>>> Most flooring adhesives are now water-based
Fast-paced
construction
No time for natural drying or manually applied moisture drying products
Lack of knowledge
- What is the solution for dry concrete
- WHEN IS CONCRETE DRY
Less permeable flooring
Vvolatile Organic Compound (VOC) regulations
>>> Most flooring adhesives are now water-based

The Solution
Aridus Technology
Drying vs. Self-Desiccation
It dries evenly throughout.
Conventional Concrete
Rapid-Drying Concrete
Drying to this depth could take years
Drying throughout the depth will take roughly 30 days
6
When Is Concrete Dry?
When moisture meets the flooring manufacturer’s
specifications.
ASTM F 1869
ASTM F 2170
Flooring Specifications
TESTING FOR DRY CONCRETE:
8
• Measure for the internal relative humidity (RH)
• Taken at 40 % of the slab depth if one-way drying
• Target: Manufacturers recommendation 80% typical
• “True Indicator”
ASTM F 2170
Relative Humidity TestTest Run at 73F and 50% RH
Why Aridus??
–Aridus consumes available water
–No failures do to moisture
–Meets ASTM and Flooring
requirements
–No flooring failures due to moisture

Value
Aridus – Value Aridus Benefits –GC
• Scheduling advantages early• Cost of sealers and curing compounds • Scheduling advantages later at TI• No unexpected Cost for topical solutions
and related operations• No downstream repair costs or damaged
reputation for floor failure• Avoid voided warranty issues
Aridus Benefits –OWNER
Prevent lost worker productivity Prevent lost property use Maximize property REVENUE ($$$)

Its estimated that vapor emission related flooring failures
cost industry in the U.S. billions of dollars annually in
damage, downtime, repair and replacement.
Deliver concrete that dries to 80% relative humidity and 5# / 1000 sf / 24 hrs MVER within
45 days at an in place cost per square foot less than today’s topical coating systems
