Base slabs help channel the water away quickly to prevent flooding.
Features & benefits
High flow drainage
When the box culverts are inverted, base slab becomes the roof of the culvert.
Different configurations are possible
Box culverts be used as bridge support, irrigation or walkway underpass.
40MPa fibre reinforced concrete is a high strength concrete used to make box culverts. The rating of 40MPa or greater means that box culverts will remain durable and robust throughout their lifetime.

Base slabs are dropped into place followed by box culverts. If box culverts run parallel, then a link slab is placed in between to enclose the middle conduit. Minimal amount of backfill is required to complete the project.
