When you order the concrete, make sure there is sufficient space for the truck to get to your basement window and that the chute can enter through this window (24 in. wide by 18 in. high). If there is not sufficient space, consult our Services section to learn more about our concrete pump service available for hard to reach areas. If you intend on pouring on a impervious surface like in the pictures, contact our sales team to learn what to do.
