Standard circular saw or wet saw with a masonry blade or diamond tip blade.

Standard masonry drill bit.

No, they do not. You may shorten the length of the planks by cross-cutting without weakening the planks.

Not normally. It may crack if dropped off of a truck or upper floor, however, it should not crack or break if dropped a short distance.

Yes, typical concrete paint or stain from your local paint or building material store can be used. We highly recommend using a silicone based concrete sealer after staining. Products we recommend can be found on our coatings page.

Yes, LumberCon™ works great as a plank. A 2" plank will span 6′ under residential design and 5′ under commercial design. A 4" plank will span 14′ under residential design and 10′ under commercial design. See our span tables.

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.

Standard deck hangers, connectors, and screws will work. Hidden fasteners also work well for securing deck boards.

Any deck plank can be used when LumberCon is used as a substructure.

LumberCon planks cure to 6,500psi within two weeks of removal from forms. For reference, regular concrete cures to 2,500psi. This special concrete is a prestressed product, is lightweight, and can be sawed and screwed.

LumberCon is not affected by salt water. Ends of boards should be sealed to avoid rusting of the exposed wires. This can be done by using Sherwin Williams Porch & Floor Enamel or a light epoxy coating.

Yes, you can use LumberCon as an alternative to traditional landscape timber. There are no issues with soil contact or insects.

We are similarly priced to other composite decking products and less expensive than Laminated Veneer Lumber (LVL). Important to note for cost estimation purposes: you will not need to purchase as much material for the substructure because of the spanning capabilities of LumberCon planks.

LumberCon offers a 25 - Year Limited Residential Warranty and a 10-Year Limited Commercial Warranty.

LumberCon planks cure to 6,500 PSI, making it very hard for liquids to penetrate the surface.

No, the wire is solid.

No.

No, do not drill through the wire.

LumberCon requires minimal maintenance. It is able to be power-washed if necessary.

LumberCon planks will not overheat when exposed to high temperatures, instead they will match the ambient temperature around them.

Small. The COEF is 0.000006 in/in/deg F. For example, a temperature change from 60F to 100F (40F) – a 20′ long structural C-plank member expands only 0.05″ or a little more than 1/32″.

Yes, you can drill a hole on the longitudinal center of the lumber.

Yes, it is better than steel. R value is 3.9 per inch thickness.

Excellent. ASTM E-84 test results are 0 with an “A” rating. Concrete products are the best protection from fire.

Almost zero moisture.

No, the prestressed concrete will maintain its strength even when it is cracked.

No. There are no chemicals in C-plank that can cause an environmental problem.

LumberCon planks are similar to LVL in regards to strength. LumberCon is typically less expensive, depending on the size.

The superior span characteristics will mean that less structural materials will be needed compared to wood. LumberCon planks require a minimal amount of screws to secure, speeding the entire installation process up.
