Drilling into Precast Concrete Box Culvert
Drilling into Precast Concrete Box Culvert
(OP)
Hello,
A contractor wants to drill into a new precast box culvert for forming the cast in place headwalls. He would fill them with grout after. Is this generally acceptable practice?
Thanks

I have seen small holes drilled into boxes and RCP many times. It should be fine, depending on the hole size, spacing, and edge distance. Call your pipe supplier for better details, they run into this all the time. Make sure they follow the directions for the grouting, especially cleaning if they don't get around to grouting right away.
