Joint & Curl Free Slabs
How to reduce and eliminate joints and curling?
GreenCanvas Expansive Component
Green Canvas expansive component is a cementitious, inorganic powder – when added to a standard concrete mix it 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 is 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 test methods and procedures.
Cut Your Labor
Eliminates the labor needed to cut and fill joints. Enables larger, monolythic pours.
Cut Your Downtime
No need to schedule concrete cutting or joint filling. No added time to typical placement schedule, GreenCanvas is added in the mix.
Cut Your Environmental Impact
Repair and tear out waste due to cracking is eliminated. End result – a more sustainable slab.
Joint and Curl Free Concrete
Green Umbrella GreenCanvas expansive component creates durable, sustainable concrete.
Green Umbrella Canvas Control System
The Canvas Control System addresses common and frustrating enemies of Architectural Concrete: curling, cracking and excessive joints and joint filler. GreenCanvas allows design professional to design the ideal concrete floor from pour to polish. CSI format specifications and products that Cut Labor, Cut Downtime and Cut Environmental Impact while being introduced on the day of placement.
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.
