Concrete Dry Shrinkage Control

How to control dry shrinKage cracking

GreenCanvas Expansive Component

Green Umbrella® GreenCanvas™ expansive component is a cementitious, inorganic powder. When added to a standard concrete mix, will produce a shrinkage compensating concrete (SCC); Type G (ACI-223R-10).

GreenCanvas is a specialty concrete component classified by type based on the chemical mechanism used to obtain expansion in the concrete matrix during the curing process. Structure design, concrete mix design, and placement guidance are provided by the American Concrete Institute (ACI) document ACI 223, “Guide for the Use of Shrinkage Compensating Concrete.” Compliance and quality assurance can be measured by standard ASTM tests and procedures.


  • Eliminates the labor needed to cut and fill joints
  • Enables large pours


  • No need to schedule concrete cutting or joint filling 
  • GreenCanvas is added to the mix


  • Repair and tear-out waste due to cracking is eliminated
  • The end result is a more sustainable slab

Dry Shrinkage Control

The Green Umbrella® GreenCanvas™ expansive component creates durable, sustainable concrete.


Standard Concrete

  • Few, if any, shrinkage cracks
  • Large, monolithic pours
  • Savings over traditional slabs requiring joints and joint filler

Bridge Deck

  • Eliminates joints and minimizes dry shrinkage
  • Reduced intrusion into the concrete
  • Reduced exposure of rebar to corrosion and elements
  • Chloride exposure is reduced
  • Reduced washboard effect on highways due to curling

Polished Concrete

  • Elimination or reduction of shrinkage cracks
  • Promotes even aggregate reveal
  • Few, if any, joints, enhancing the appearance and improving cost savings
  • No issues with slab curl at joints or around edges

Additional Features & Benefits

  • Reduces or eliminates dry shrinkage cracks
  • Reduction in joints, allowing large monolithic pours
  • Eliminates slab edge curling
  • Transparent in the mix
  • Cementitious
  • Expansion occurs independently
  • Does not require any special handling, placing, finishing, or curing techniques and procedures
  • Sustainable
  • Does not contain chemicals, unlike most shrinkage-reducing admixtures
  • Cost savings offsets costs incurred cutting and installing joints
  • Reduction in joints eliminates costly installation repairs on joints
  • Cuts labor, downtime, and environmental impact
