What kind of saw is needed to cut the Concrete Lumber?
STANDARD SKILL SAW WITH MASONRY BLADE.

What kind of drill bit is required?
STANDARD MASONRY DRILL BIT.

Do you weaken the lumber when you cut the prestress wire?
NO, YOU CAN CUT THE LUMBER TO SHORTEN IT BY CROSS-CUT (BUT DO NOT RIP) WITHOUT WEAKENING THE BOARD.

NOT NORMALLY. IT MIGHT CRACK IF DROPPED OFF A TRUCK OR UPPER FLOOR, BUT NOT IF IT WAS DROPPED A FEW FEET.

Can you paint and stain the Concrete Lumber?
YES - ANY COLOR. TYPICAL CONCRETE PAINT OR STAIN FROM YOUR LOCAL PAINT OR BUILDING MATERIAL STORE.  PRODUCTS WE RECOMMEND CAN BE FOUND ON OUR COATINGS PAGE.

Will the Concrete Lumber work as a decking plank?
YES, CONCRETE LUMBER WORKS GREAT AS A PLANK ("SUPER-SPAN"). A 2x PLANK WILL SPAN 6' UNDER RESIDENTIAL DESIGN AND 5' UNDER COMMERCIAL DESIGN. A 4x PLANK WILL SPAN 14' UNDER RESIDENTIAL DESIGN AND 10' UNDER COMMERCIAL DESIGN. SEE OUR SPAN TABLES.

How do you transport the Concrete Lumber?
IT IS RECOMMENDED TO LIFT AND CARRY THE LUMBER JOIST-WISE - NOT PLANK-WISE. FOR EXAMPLE, A 2"x6" PIECE SHOULD HAVE THE 6" SIDE HELD VERTICALLY.

How is the lumber put together?
STANDARD DECK HANGERS, CONNECTORS AND SCREWS WILL WORK.

Can I use composite lumber with Concrete Lumber?
ANY DECK PLANK CAN BE USED ON A STRUCTURAL CONCRETE LUMBER FRAME.

What psi is the Concrete Lumber? What makes this different than regular concrete?
THE PATENTED CONCRETE LUMBER TYPICALLY HAS A MINIMUM 4,000 PSI. THIS SPECIAL CONCRETE IS A PRESTRESSED COMPOSITE PRODUCT, IS LIGHTWEIGHT, AND CAN BE SAWED, NAILED AND SCREWED.

Can you cut/ rip a 2x12 to make two 2x6 boards?
YES, BUT THE SINGLE WIRE EDGE MUST BE INSTALLED ON THE DOWN-SIDE!!

Is the Concrete Lumber affected by salt water?
NO.  WE ALSO OFFER DOT (DEPARTMENT OF TRANSPORTATION)-STYLE FACTORY COATING WITH A 50 YEAR WARRANTY.

Can Concrete Lumber be used for landscape timbers? Can you bury it without any concerns?
YES. THERE ARE NO ISSUES WITH SOIL CONTACT OR INSECTS.

Where do I buy Concrete Lumber?
MOST LUMBER YARDS HAVE ACCESS TO THE LUMBER OR WE SHIP FACTORY DIRECT.

How much does Concrete Lumber cost?
SLIGHTLY MORE THAN GROUND CONTACT PRESSURE TREATED WOOD. LESS THAN EXTERIOR LVL.

How long will Concrete Lumber last as a joist?
THE WARRANTY IS FOR 20 YEARS, INCREASING TO 50 YEARS WITH THE FACTORY "DOT" COATING.

Does Concrete Lumber stain or absorb water?
THE UNCOATED LUMBER PRODUCT CAN BE STAINED ANY COLOR. WE SUGGEST UGL PRODUCTS. THE LUMBER THAT IS FACTORY COATED TO RESIST WATER HAS LIMITED COLOR CHOICES.

Can the pre-stressed wire be used as a conduit?
NO, THE WIRE IS SOLID.

Do I have to ground the Concrete Lumber?
NO.

Will drilling effect the wire?
DO NOT DRILL THROUGH THE WIRE.

What care and maintenance do we need to care for Concrete Lumber?
NONE FOR ANY FRAMING LUMBER.

Does temperature change cause concern with Concrete Lumber?
NO, IT IS A STABLE PRODUCT.

What is the expansion and contraction for the material?
SMALL. THE COEF IS 0.000006 IN/IN/DEG F. FOR EXAMPLE, A TEMPERATURE CHANGE FROM 60F TO 100F (40F) - A 20' LONG STRUCTURAL CONCRETE LUMBER MEMBER EXPANDS ONLY 0.05" OR A LITTLE MORE THAN 1/32".

Can the Concrete Lumber be drilled to accommodate wiring and pvc lines in floor joists?
YES, YOU CAN DRILL A HOLE ON THE LONGITUDINAL CENTER OF THE LUMBER.

Does Concrete Lumber have any insulating value?
YES, IT IS BETTER THAN STEEL. R VALUE IS 3.9 PER INCH THICKNESS.

What is the fire performance of Concrete Lumber?
EXCELLENT. ASTM E-84 TEST RESULTS ARE 0 WITH AN “A” RATING. CONCRETE PRODUCTS ARE THE BEST PROTECTION FROM FIRE.

What is the moisture content of Concrete Lumber?
ALMOST ZERO MOISTURE.

Will a surface or spider crack on the lumber affect its performance?
NO, THE PRESTRESSED CONCRETE WILL MAINTAIN ITS STRENGTH EVEN WHEN IT IS CRACKED.

Are there any hazardous ingredients in the Concrete Lumber that could leach out and cause an environmental problem?
NO. THERE ARE NO CHEMICALS IN CONCRETE LUMBER THAT CAN CAUSE AN ENVIRONMENTAL PROBLEM.

How does Concrete Lumber compare to LVL on strength and pricing?
CONCRETE LUMBER IS SIMILAR TO LVL ON STRENGTH AND TYPICALLY LESS EXPENSIVE, DEPENDING ON THE SIZE. CONCRETE LUMBER IS LESS EXPENSIVE THAN LARGER BOARDS.

How does Concrete Lumber compare to standard lumber with installation time?
IT IS SIMILAR, BUT EXPERTS PREDICT THAT CONCRETE LUMBER WILL GET FASTER AS CONTRACTORS GAIN EXPERIENCE. THE SUPERIOR SPAN CHARACTERISTICS WILL MEAN THAT LESS CONCRETE LUMBER WILL BE NEEDED COMPARED TO WOOD.
