Box culverts are gaining in popularity across the country and we’re getting more and more questions on how to seal box culverts properly.
And it’s not just precast producers asking about these options, but contractors in the field and engineers responsible for designing and using box culverts in a variety of applications.
Some of the more common applications include:
- Stream culverts
- Storm water storage
- Material handling
They are also available in a wide-variety of standard sizes as well as specific designs meeting the features and standards of almost any project.
Profile Rubber Gaskets for Box Culverts
Our Type 4G Profile gaskets and Reduced Friction Seal pre-lubricated gaskets are available for watertight applications. The Type 4G and 4F profile gaskets are designed to seal single offset joints and also designed to be self-centering reducing the homing force when joining a box culvert than our o-ring product.
Butyl Rubber Sealant
Pro-Stik and EZ-Stik are both butyl sealants containing no bitumen or asphalt materials meeting ASTM C-990, Section 6.2 Butyl Rubber. Our butyl sealants are all weather, therefore, they perform better in both hot and cold weather unlike mastic or blended materials. These rubber sealants meet or exceed:
- ASTM C 990 - Standard Specification for Joints for Concrete Pipe, Manholes, and Precast Box Sections Using Preformed Flexible Joint Sealants. Section 6.2.1 Butyl Sealants (elastomeric polymer shall be butyl rubber only)
Butyl Exterior Joint Wrap
Exterior joint wraps are a great secondary seal for use with other sealing products for box culverts. Both 12" EZ-Wrap Plastic and EZ-Wrap Rubber are sized for box culvert joints and meet ASTM C 877.
Cellular Joint Filler
Flexible closed cell neoprene sponge is a quick, easy solution for fillling box culvert joints. We offer a variety of shapes and sizes for soil and silt tight applications meeting ASTM D 1056.
