"Concrete flat work" encompasses basement floors, driveways, garage slabs, steps, sidewalks and patios – any slab work that is not supporting significant structural components. Here are the steps Greystone follows to ensure the success of your project. Greystone uses Cemstone products. For more information visit www.cemstone.com.

BASEMENTS FLOORS
	All basement floors are poured with 3500 PSI concrete.
	Super plasticizers are added to the concrete mix in the warmer months to make the concrete slump pourable. Super plasticizers are a better additive that water because they do not diminish the strength of the concrete mix. They also reduce shrinkage which in turn minimizes cracking.
	Zip strips - control joints - are always placed in locations where basement floors are likely to crack, particularly around posts or off corners. The zip strips help control cracking, but they won't eliminate it entirely.
	Basement floors are hand troweled two to three times to ensure a level, smooth finish.

GARAGE FLOORS
	All garage floors are poured with a 4000 PSI concrete mix containing fiber mesh and 6% air content. (In fiber mesh, one inch long fiberglass hairs are incorporated into every inch of the concrete for added strength and crack control.)
	Super plasticizers are added to the concrete mix in the warmer months to make the concrete slump pourable. Super plasticizers are a better additive that water because they do not diminish the strength of the concrete mix. They also reduce shrinkage which in turn minimizes cracking.
	Physical or zip strip control joints are used to allow for expansion/ contraction due to climate changes
	Garage floors are sloped three inches from front to back for drainage.
	The front lip of the garage pad is beveled to reduce the likeihood of water entering.
	Floors are hand troweled two to three times to ensure a level, smooth finish.
