HOHMANN & BARNARD, INC.
EXPANSION & CONTROL JOINTS
Backer Rod
Backer Rod is an ideal non-absorbent, compressible backup material inserted into a joint to control sealant depth. It creates a backstop to allow proper sealant tooling and allows proper sealant of the joint surfaces. Backer Rod forms a proper bond between the back-up material and the sealant. It can also be used as a temporary joint seal. - Standard Backer Rod is an extruded round, closed cell, low density polyethylene foam material with a skin-like outer texture. - Commonly used for glazing operations, window and door applications, expansion joints, curtain wall joints, partitions, log construction or pavement joints. - Highly flexible and compressible for easy installation. - Compatible with butyl, polysulfide, acrylic, polyurethane, silicone and most other cold sealants. Available Sizes: diameters from 1/4” to 6”. ASTM D1622, ASTM D1621, ASTM C5090, ASTM C335.
Soft Rod
Soft Rod is a closed cell material that is much lighter than standard Backer Rod. This allows for a product that is much lower in density and much easier to work with. It is compatible with butyl, polysulfide, acrylic, polyurethane, silicone and most other cold sealants. Available Sizes: 3/8”, 5/8”, 7/8”, 1 1/8”, 1 1/2”, 2”, 2 1/2”, 3” and 4” diameter. ASTM D1622, ASTM D1621, ASTM C5090, ASTM C335.
Removable Expansion Joint Cap
This flexible, highly resilient polystyrene product is used to form and fill horizontal and vertical joint applications. Before concrete placement, install on top of the existing expansion joint material to form precise horizontal and vertical intersections within the concrete. With little clean up, the removable top is then snapped off without any effort, and the result is a permanent channel, ready to receive caulk or sealant. - Use at any depth, as well as with any other expansion joint product. - Requires no further maintenance, when installed correctly. - Ideal for molding concrete to maintain uniform edging. Available Sizes: 1/2˝ x 1/2˝, 3/4˝ x 1/2˝, 1˝ x 1/2˝ X 10’ lengths. 50 pieces per box.
