Field Moisture Mitigation Test

Field Moisture Mitigation Test

4” Lightweight concrete over 2nd level structural metal deck

  • Field testing on 30 day old lightweight concrete deck 4” thick with high moisture content
  • Moisture testing was performed on two separate areas of an exposed deck (masonry wall, no windows)
  • Both control and test area had initial readings of 94% RH at a depth of 2”
  • Three testing probes were inserted in a triangular pattern within a 15’ x 15’ area to be treated with DRYCRETE Moisture Stop
  • A single testing probe was further inserted at 2” depth in an untreated area 20’ away from the treated area
  • After 45 days with heavy rainfall recorded in the month of June 2011, and with a full week of sunshine prior to final testing, the results were convincing:This is proof that under adverse conditions, with observed puddling water preventing an accurate field test on two separate occasions, DRYCRETE Moisture Stop proved to lower the RH moisture content to an acceptable level to accept standard floor coverings or coatings.
    • Control area (untreated) returned a moisture reading of 91% RH.
    • The DRYCRETE Moisture Stop treated area had a moisture reading < 80% RH on one probe and 81% RH on the other two probes.
  • This is proof that under adverse conditions, with observed puddling water preventing an accurate field test on two separate occasions, DRYCRETE Moisture Stop proved to lower the RH moisture content to an acceptable level to accept standard floor coverings or coatings.

 Note: The tests were conducted by the reputed moisture testing company Flood Testing Laboratories, Inc. in Chicago, Il. All tests were performed on site, under normal exterior atmospheric conditions during a period of heavy precipitation with record rainfall recorded during the month of June 2011.

Meets or exceeds the following testing criteria and guidelines

ASTM C-67 Section 7: Water Absorption
Water absorption of treated concrete was decreased by at least 90%.

ASTM C-67-Section 9: Suction
The rate of absorption of concrete (suction) was decreased by as much as 98%.

ASTM C-67-Section 10: Efflorescence
Efflorescence and leaching are eliminated.
 
ASTM C-67-Section 65: ORF Method, Dusting Resistance
Treated concrete is four times more abrasion (dusting) resistant.
 
ASTM C-672-760: Scaling resistance to Deicers
Treated concrete imparts excellent resistance to salt attack.
 
ASTM C-666: Freeze Thaw Resistance
Significanty Improves resistance to freeze-thaw damage.
 
ASTM C-856: Petrographic Analysis
Specimens have at least 50% greater density, which results in reduced permeability.
 
ASTM C-1585: Rate of Absorption of Water by Hydraulic Cement Concrete
Demonstrates a measurable reduction in water absorption after treatment of the concrete block.
 
ASTM D-2047: Slip Resistance
Wet and Dry testing showed that treated concrete had a much improved slip resistance.
 
ASTM E-96: Moisture Vapor Transmission
An effective barrier against water vapor emission, without loss of breathability reducing vapor emission by > than 75%.
 
ASSHTO T259-80: Chloride Ion Penetration
Reduces chloride intrusion in hardened concrete.
 
Reduces the depth of water penetration by 94%
 
CRD C-48-73: Hydrostatic Pressure Resistance
Sealed specimens at 45 psi, the equivalent of 115 ft of standing water while field testing has shown efficacy at near 300 ft.
 
CRD-52-54: Abrasion Resistance
Significantly increased abrasion resistance.

PREVENT BLUSHING

Whitening of concrete sealers – also known as ”Blushing”
+

PREVENT SPALLING

When the water in concrete is able to freeze, it then expands & causes damage to concrete surfaces.
+

PREVENT MOISTURE ISSUES

Leaves no surface residual to impede or hinder bonding of any coatings or adhesives.
+

PREVENT EFFLORESCENCE

A white crystalline powder-like substance which forms on surface of concrete, stucco, brick or masonry.
