VERTASTONE™ONE DAY WALL
CARVABLE CONCRETE WALL SYSTEM
PRODUCT DESCRIPTION: Concrete Earth’s Vertastone™ One Day Wall System is an easy to use three-component series of admixtures and surface treatments which can be added to regular low slump concrete to provide a form-free stackable, slow setting concrete that can be carved, stamped or formed to simulate realistic stonework. Component A “Wall Aid” is a modified mid-range plasticizing admixture which allows higher early strength formation of the concrete by reducing water demand by approx. 15-20%. Component B, “Slow Set” is a viscosity modifying, set retarding admixture which provides added rheology (thickness) of the mix to allow concrete stacking without form support, as well as extending final set times to allow the primary carving of the surface. Component C, “Easy Slick” is a topically applied surface finishing treatment which extends tooling time and allows delayed hydration at the surface for final stamping and texturizing needs.
BENEFITS:
- Allows placement of free standing walls without additional formwork or support structures.
- Walls can be carved, stamped and stained to mimic realistic natural stone formations
- Pouring form free allows great labor savings to traditional cast retaining walls
- Cast walls will be monolithic in structure and more resistant to any movement or blowout than walls made of individual cmu’s (cast masonry block units) or by use of actual stones.
- Walls can be customized and colorized to match or enhance the natural surroundings or buildings

This data is based on controlled laboratory tests. Slight variations from the results shown here may be experienced as a result of jobsite conditions, different mix design components, or other factors.
SURFACE PREPARATION: Areas to have walls erected should have a proper footing base poured and installed with sufficient exposed rebar to bond to the newly constructed wall.
MIXING DIRECTIONS: Barrel trucks: Concrete that is used should be manufactured of an “8 bag” mix design, and should also be ordered at a reduced 2 inch “low slump” consistency (thick mix).One bag of fly ash can be added to this mix to help improve surface troweling and carving properties, as well as help increase end strengths. Once concrete arrives, add 1 gallon each of One Day Wall Component A Wall Aid and Component B Slow Set per yard of concrete to the mixer and let the drum rotate for an additional 5 minutes until the admixtures are dispersed evenly. Volumetric trucks: Dilute each admixture 1 to 1 by volume with potable water so that they will pump more easily. Place each of the diluted admixtures into their respective high flow admixture tanks. Set each flow meter so that they dispense the diluted admixture from each of the tanks at a rate of 1 quart (32 oz.) of diluted admixture per every hundredweight (cwt) of cement.
PLACEMENT: Place concrete as necessary to achieve an ideal wall base to carve onto. Do not exceed more than 5 feet high in one pass as the concrete may tend to settle or sag if applied over this height. One Day Wall Component C Easy Slick should be diluted 1 to 9 with potable water and transferred to a low pressure trigger sprayer before spraying. Apply as necessary to the carved concrete surface to allow more stamping and finishing time as the wall starts to take shape.
CURING, STAINING & SEALING: After final set is achieved, moist cure the concrete surface to help promote proper strength gain and reduce the chance of any shrinkage cracking. After 24 hours of wet curing, the walls can be stained using Concrete Earth’s Stone Transitions Natural Series Stains which are available in 12 earth tone shades for custom colorization. Refer to Stone Transitions technical data for application instructions. The stained wall can then be sealed with Specco’s Waterstopper S-5 silicone based water repellent which will provide a natural appearance that protects the stained concrete from weathering and freeze thaw cycling attack.
CAUTIONS: Concrete Earth’s One Day Wall Components will freeze but may be completely restored by thawing above 32º F (0º C) and thoroughly mechanically agitating before use. Do not use pressurized air for mixing or agitation. Concrete Earth’s One Day Wall Component A Wall Aid should be stirred before using if the material has set for an extended period (3-6 months).
