The Flexi-FORM from Frank Wall Enterprises is a concrete forming board made of 100% recycled HDPE plastics. The flexible concrete form board can be used to form and pour concrete pool decks, sidewalks, patios, driveways and any concrete surface with curve or tight radii. Designed with recessed areas on the back side that stiffen the board while providing flexibility, the weather resistant forms can bend to a 6-in. radius without breaking in freezing temperatures. Flexi-FORM is available in 1/2-in. by 3 1/2-in. by 50-ft. rolls and in 1/2-in. by 3 1/2-in. by 12-ft. planks.
