CONCRETE BLOCK FOUNDATIONS

Concrete Block foundations have been called "Hidden Gems" for good reason.

	Their durability and strength have been well proven.
	They are straight, plumb and level, ensuring the integrity of the above-grade walls that depend upon them for structural support.
	Concrete block foundations are dry. The hollow cores in each block prevent sweating in summer and frost build-up in winter.
	The modular components readily allow for future design changes.

GREYSTONE ENSURES THE STRENGTH OF YOUR FOUNDATION SYSTEM THROUGH THIS SEQUENCE OF EVENTS:

Footings:
	The footprint of the foundation is staked out
	The excavation depth is verified
	All measurements are checked and double-checked with the use of Calculated Industries Construction Master 3
	Digging and forming are completed
	Draintile chases are placed, if required
	Re-bar is positioned, if required
	Concrete is poured
Blockwork: The below-grade stuctural support for your above-grade wall systems.
	The layout of the structure is completed: block installation begins.
	At the seventh or eighth course, heights, levels and right angles are doudle checked.
	All exterior walls are struck flush and tooled on both the outside and inside.
	All 12" and 8" blocks on the top course are sealed.
	Core pours are placed in block voids. Spacing depends on soil weight conditions as well as wall height.
	Anchor bolts or straps fasten wood framing to the foundation. These are set in block cores and block webds with mortar.
	The foundation system goes through a final check for level and squareness.
Mortar: The mortar used between all block joints is a mixture of lime, Portland Cement, sand and water. this mixture results in strengths from 1800 to over 2200 PSI.
Warranty: The structure of walls is warranted for 10 years.

POURED WALL FOUNDATIONS

Their durability and strength have been well proven. Solid concrete has an ultimate flexural strength.

	They are straight, plumb and level, ensuring the integrity of the above-grade walls that depend upon them for structural support.
	Poured walls need virtually no maintenance.
	Fire resistant because of it’s increased density.
	Affordability controlling cost is one of the biggest concerns of homebuilders and buyers alike.
	Efficient modern construction methods make poured wall basements cost competitive with block walls.

	Draintile chases are placed, if required
	Re-bar is positioned, if required
	Concrete is poured
Poured walls:
	The layout of the structure is completed: setting of the panels begins, re-bar properly placed as required. After all panels are set, a final check of all squares is done to ensure the building is ready for the concrete.
	Anchor bolts or straps fasten the wood framing to the foundation. These are set in the walls after they are poured.
