Delivery & Install Options

Box Culverts are CE Marked & Manufactured to EN 14844, full specification available in the Declaration of Performance

Box Culverts are manufactured to allow the use of spherical head anchors or threaded socket lifters for lifting.
On delivery to site Moore Concrete recommends:

  • they are lowered onto a firm level base
  • they are moved by lifting and never by dragging
  • in cold weather, open lifting sockets or protected from freezing and bursting

Preparing the trench keeping to the specified line and gradient, the trench should be excavated to a width equal to the Box Culvert width plus about 600mm, with a flat well prepared base.

Joints maybe left open in certain cases but a preformed strip compressed within the joint is commonly used. The strip should be applied to the Box Culvert just before it is laid in the trench.

A Box Culvert line is usually laid from the downstream end with sockets facing upstream to receive the next Box Culvert to be laid.

When a preformed strip is used, joints are closed by pulling against the Box Culverts previously laid.

Back filling should commence as soon as possible after the culverts have been laid.
