1. Growth Crystals used on
Blondo Street in 2015
Presented by Logan Contractor Supply
LOGAN CONTRACTOR SUPPLY IS COMMITTED TO IDENTIFYING / OR
BEING PART OF THE TEAM IDENTIFYING THE PROBLEMS
WE HAVE COMMITTED OURSELVES TO FIND SOLUTIONS
FOR THESE PROBLEMS.

2. Let’s take a look

3. POROSITY OF CONCRETE
 ALLOWS MOISTURE TO TRAVEL FREELY INSIDE CONCRETE
 INCREASES ABSORPTION OF CONTAMINATING MATERIALS
MOISTURE CAUSES CONCRETE DETERIORATION & FAILURE
 INCREASES THE ABSORPTION OF CHLORIDES FROM DE-ICING
MATERIALS
 DISSOLVES & ACTIVATES FREE ALKALI MATERIALS THAT ATTACK THE
CONCRETE MATRIX
 THE FORMATION OF CALCIUM OXY-CHLORIDE
 ACCELERATES THE CORROSION OF STEEL
 BREAKS THE CONCRETE MATRIX DUE TO FREEZING & THAWING
 REDUCES ADHESION OF COATING MATERIALS

11. SO WHAT IS BEING DONE TO
CONTROL THESE IDENTIFIED
PROBLEMS?

12.  Curing Compounds
 Epoxy Resins
 Modified Acrylic Latexes (PVA)
 Silanes**
 Siloxanes**
 Silicones
 Linseed Oil
 Sodium Silicates
 Stand Alone Concrete Mix Designs

13. Now let’s take a look at

14.  Crystal Growth liquid applied products are unique water
based, non-toxic and can be both hydrophilic and
hygroscopic.
 All Crystal Growth liquid applied products contain the
hydrophilic crystal which permanently fills capillaries and
voids within the concrete substrate.
 Some Crystal Growth liquid applied products also incorporate
a hygroscopic crystal which continues to grow within the
concrete substrate seeking out moisture and further blocking
pores and capillaries deeper within the concrete.

15.  Crystal Growth liquid applied products continue to block
moisture and moisture vapor even under constant high
hydrostatic pressure and continue to seek out new sources of
moisture.
 Crystal Growth liquid applied products crystallization activity
is continuous while moisture is present.
 Growth crystals become inactive during dry
conditions and are fully reactivated when moisture
and moisture vapor are present.

25.  Seals hairline cracks up to one 16th inches in width
 Seals inner surface of large cracks preventing
water from causing further damage
 Increases the adhesion property of repairing
materials to concrete in the repaired cracks

33. SO WHAT IS THE COST?

34. 40% solids Silane(5gal) price per sf, at 150sf
per, $.31/sf one application / re-apply 2-3 yrs
100% solids Silane(5gal) price per sf, at 200sf
per, $.38/sf one application / re-apply 4-5 yrs
..Growth Crystals (5gal) price per sf, at 150sf
per, $.45/sf. only application / no re-application
needed

36. Would the cost of implementing a pro-active
preventive maintenance plan be more than what you
are currently paying for repairs on your concrete by
doing nothing ?
Keeping in mind the rules were changed for
your concrete, when the technology for better
ice control advanced into liquid form creating
Calcium Oxy-Chloride.

37. Growth Crystal Treated Concrete

38. One Application on Concrete:
 Will be waterproofed and sealed against de-
icing chemicals for the life of the Concrete
 Will be resistant to most aggressive & harmful
chemicals such as jet fuels, oil, & acids
 Will be protected against spalling,
efflorescence, stress corrosion cracking, and
damage from freeze-thaw cycles
 Reinforcing steel will be protected against
deterioration and corrosion
