This document discusses Anti-Hydro, a non-corrosive admixture that has been used since 1904 to integrally waterproof concrete and increase its workability, strength, hardness, and durability. Anti-Hydro reacts with portland cement to produce more complete hydration, reducing water requirements and shrinkage while increasing early and ultimate strength. This results in impermeable, hard, and non-dusting concrete. When added to concrete or other cement mixes, Anti-Hydro produces dense, durable, waterproof materials. It works by increasing hydration from typical ranges of 65-70% to around 95%, yielding denser, harder, and impermeable materials that act as a vapor barrier.

Hardness, and Durability

3. "Anti-Hydro " is a combination of organic and
inorganic chemicals that reacts with portland
cement to produce more complete hydration.
Water requirements, bleed water and
shrinkage are reduced. The increased
hydration provides internal curing and a much
harder cement paste. "Anti-Hydro " increases
the early and ultimate strength of concrete.
These combined reactions produce
impermeable concrete that is hard and non-
dusting.

produces dense, durable, waterproof
concrete

5. How "Anti-Hydro" ® Works:
• "Anti-Hydro" ® works with any product containing Portland cement
(concrete, mortar mix, stucco, & tile grout) - in other words, all your
work!
• You add "Anti-Hydro" ® to your mix and follow our easy special
instructions.
• "Anti-Hydro" ® will do two things when you add it to your concrete, tile
grout, mortar or stucco:
1. "Anti-Hydro" ® will raise the percentage of hydration of this
mix (the amount of cement that actually chemically reacts
with the water) from the usual 65% to 70% range to
approximately 95%.
2. This is a significant change to the final properties of the
product which yields denser, harder material which is
impermeable to water and a near total vapor barrier as
well.
• "Anti-Hydro" ® is a high-range accelerator too. This means that the
concrete mix will harden far faster than normal and that means when
it’s used in winter it will harden before it freezes. And, it allows for far
faster installation… more control over your work in less time.

6. •Waterproofing
Complete waterproofing protection for concrete, masonry, stucco, precast concrete,
structural concrete, swimming pools, tanks, basements, chimneys, cement pargeting,
patching & underground utility work
•Cold Weather Protection
Keeps concrete & mortar from freezing, sets quickly
•High Strength
Dramatically increases strength
•Hardening & Densifying
Over 30% harder and denser
•Water Vapor Control
Reduces All Vapor Transmission up to 85%
•Improved Bonding
Bonds new concrete – the bond is stronger than the concrete itself
•Increased Abrasion Resistance
Resists scratches, gouges and wear due to increased hardness

11. 5 or 10 Year Maintenance Guarantee
Because of the way Anti-Hydro affects the properties of
concrete, an optional waterproofing warranty is offered
for your project. Anti-Hydro field supervision is required
but this assures that the job is done right.
