We re already there Front page photos courtesy of Ross Chandler Photography. Plus, with Reward ICFs you can eliminate additional steps in the field because of our variety of straight, corner and specialty forms, universal design, at-a-glance markings and internal ties every six inches to produce time savings from initial stacking through subcontractor finishing. And no one helps you deliver benefits to your customers like Reward with walls that reduce energy costs, withstand tornadoes, fire, earthquakes and hurricanes, and lock out noise, outside allergens and mold. The information in this booklet is for illustration purposes only. The desired result when installing a steel-reinforced concrete wall is a wall that is straight, true and plumb. There is more than one method that will correctly achieve this result. Always refer to the most current Reward Wall Systems Product Manual for specific installation information.

6 First Things First 1 Properly installed footings are the key to quick and accurate installation. Footings should be smooth, square and level to ensure walls are straight, plumb and level. Refer to your local building code for required dimensions and reinforcement. 2 Use one of several methods to attach formwork to footing: 1. Anchor inch metal starter track along chalk line to straddle inside or outside layer of foam. 2. Anchor 2x wood cleats along exposed face of inside layer of foam or anchor 2x wood cleats along exposed face of outside layer once two courses are stacked. Shim or shave bottom of form to level up the first course. 3. Glue the bottom of the first course of forms to the footing.

7 3 Strike a chalk line on the outside edge of the wall location. Follow building code requirement to determine the required size, length and spacing of vertical footing dowels. Consult Reward s Product Manual for reinforcement requirements for single family residential projects. Work with an engineer for commercial projects. 4 Vertical wall reinforcement is typically inserted down through the formwork once the wall forms have been stacked to their final height. There are two favored methods to secure vertical rebar to reinforcement dowels: 1. Place a PVC collar over footing dowels or 2. Create 2-inch deep depressions in top of footing at wall reinforcement locations. Consult local building codes for approved methods.

8 5 Common Seam Set corner blocks first, then work out in both directions toward the middle of each wall. The location where a full block is cut to close the required corner to corner dimension becomes the common seam. To start the second course, flip the corner blocks to stagger the seams between blocks and work out in both directions. Cut again at the common seam location established on the first course. This will maintain the alignment of form ties out from the corners on both sides of the common seam. 6 Secure the corner blocks to the straight blocks with horizontal wire hooks by connecting the block ties inside the forms on either side of the joint. Apply bracing on both sides of the corner.

9 7 Continue to install horizontal reinforcement as required as the forms are stacked. Vertical reinforcement will be inserted down through the formwork once stacking has reached the final height of the wall. Our ICF ties can accomodate a lap splice of up to 2- #5 rebars without being tied. Lap Splice 8 Assemble and install all door and window bucks as wall forms are being installed, making sure they are braced, straight, level, plumb and secured to the wall. Install all reinforcement required around each opening.

10 9 Bracing should be placed a maximum of 6 feet on center along one side of each wall. Windows and doors should be braced separately. Proper bracing helps ensure straight and plumb walls. 10 Walls are most often braced from the inside, but bracing on the outside is also an option. Windows and doors can be braced to the outside to reduce inside clutter. At this stage, you will want to be sure that penetrations through the wall for vents, outlets, fixtures and utility lines have been properly planned for, installed and reinforced. Be sure to provide proper bracing at T-wall intersections.

11 11 Anchor bolting a ledger board prior to concrete placement allows joist hangers to be used to frame intermediate floors and external decks. Refer to Reward s Product Manual. You can also use a ledger connection system such as the system offered by Simpson Strong-Tie. Refer to the manufacturer s instructions for installation. Using Reward s ledge form and xlerator reinforcement is another option. Install the ledge form at the required floor bearing height. Wet set anchor bolts in the concrete ledge, then anchor a continuous treated plate. Floor framing can then bear on the plate. Refer to Reward s Product Manual for the allowable loading capacity of ledge form and xlerator. 12 Prior to placing the concrete, review Reward s pre-pour checklist in the Reward Product Manual. Place concrete in multiple lifts, each at a maximum height of 4 feet, properly consolidated. Reward recommends using a 3-inch reducer at the end of the hose to slow the flow of the concrete.

12 13 Reward's patented xlerator is designed to meet ACI 318 requirements and reduce labor significantly. Place the xlerator into the foam slot of the ledge form with the 90-degree side resting on the plastic ties in the wall cavity. Center the xlerator in each of the corbels. The adjacent xlerators merely need to be butted up to each other no tying or lapping is required. U.S. Patent #7,437, The Reward ledge form reinforced with the xlerator can be used to support up to 40 feet of masonry. It is easily integrated into the wall and reduces the required thickness of the foundation below. Use Reward s patented tiekey to hold the masonry to the wall to provide strength and security when installing exterior finishes. U.S. Patent #8,347,581

13 1 5 The taper top form allows for wider concrete structural bearing in the following applications: 1. A wood framed structure built on top of a Reward basement or crawl space 2. Roof trusses bearing on top of the above-grade iform wall 3. Transition from a 13-inch iform basement to a 9-inch above-grade iform wall The xlerator simplifies reinforcement requirements. Refer to the Reward Product Manual for more information. 16 As with any below-grade structure, it is important for Reward ICF walls to receive waterproofing protection. The Resisto membrane, by Colphene Soprema, is the brand of choice for Reward, as it is compatible with expanded polystyrene and performs great in the field. Any waterproofing should be installed in accordance with the waterproofing membrane manufacturer s instructions.

14 17 To easily install utilities, cut a channel into the foam with a hot knife or router to the depth required by local code. Insert the electrical or plumbing into the channel. Use EPS compatible foam adhesive or foam backer rod to hold in place. 18 The recessed fastening strips on the ends of the form ties are clearly marked on the exterior of the foam and provide continuous attachment every 6 inches on center. Any type of interior or exterior finish can be applied directly to the form. Building codes require interior EPS foam in habitable spaces to be covered by a 15-minute thermal barrier (1 2-inch drywall, for example).
