Marshalls CPM offer an extensive range of precast concrete flexible spigot and socket jointed pipes from 225mm to 1800mm to BS EN 1916:2002 Class 120, ovoid pipes and perforated pipes for use in both foul and surface water applications.

Concrete pipes dating back to Roman times have been discovered in the United Kingdom and users of Marshalls CPM precast concrete pipes have the security of a design life of 120 years that ensures lifetime costs are kept to a minimum.

All precast concrete pipes manufactured to class 4 (DC4) sulphate resistance in accordance with the recommendations of BRE Special Digest

With an inherent strength and durability, concrete is an environmentally friendly and cost effective material that provides the following benefits:
  • Increased cost savings
  • Quicker installation
  • Lower environmental impact

Tabled dimensions are for guidance only.  For accurate dimensions and weights please contact the Technical team, as these may vary


Marshalls CPM is able to offer precast concrete pipes in BIM (Building Information Modelling) which is now a requirement for all government construction projects.

  • Are there any precautions to take for concrete pipes laid to steep gradients?

    It is recommended that anchor blocks be cast into the ground every 3 or 4 pipe joints behind the socket (also consider installing packers on the face of sockets to prevent concrete to concrete contact).

  • Do you supply certificates of conformity for your standard products?

    No – they are not required as our standard products are certified under the BS ‘Kitemark’ system – certification can be viewed here.

  • How frequent should I be testing the pipeline during installation?

    It is highly recommended to test the pipeline every 3 or 4 pipes laid as an absolute minimum (do not wait until whole line is installed before carrying out such test).

  • What are the appropriate ‘roughness values’ for concrete pipes?

    Roughness values are:

    Foul sewers: 1.5mm.

    Surface water sewers: 0.6mm.

  • What concrete pipes are generally reinforced?

    Marshalls CPM concrete pipes are generally reinforced in sizes DN675 and above (it is possible to reinforce some of the smaller sizes and also to provide un-reinforced pipes in some of the larger sizes – usually made to order).

  • What is the maximum permissible velocity in concrete pipes?

    Limits are not normally placed on maximum velocities but certain criteria such as the potential for erosion should be considered for steep gradients.

  • What is the maximum working pressure that concrete pipes can withstand?

    Concrete pipes are designed to operate at low heads of water. The BS performance requirement is set at a minimum of 0.5 bar.

  • What is the most likely cause of air test failure for a concrete pipeline on site?

    Common causes of air tests failures include:

    • Displaced seals (usually due to use of wrong pipe lubrication during installation).
    • Poor laying technique.
    • Faulty testing equipment.
    • Poor seal between testing equipment and face of concrete pipe.
  • What is the recommended maximum jetting pressure acceptable for concrete products?

    5000 psi is the generally accepted maximum, although higher pressure can be accommodated by concrete drainage products.

  • What materials can be used as backfill for a concrete pipeline?

    In many situations the ‘as-dug’ trench material is suitable for backfill (should be readily compactable and free from large boulders etc).

  • What sizes of concrete pipes are subject to testing when installed?

    It is common practise to carry out air or water testing of pipes normally up to DN750 and a visual inspection above this size.

  • What strength of concrete pipes is available?

    Circular concrete pipes are all manufactured to strength class 120 (minimum crushing load for a particular size of pipe is equal to 120 multiplied by DN of pipe divided by 1000).

  • What typical joint gaps should be achieved when jointing concrete pipelines?

    Joint gaps between pipes should be measured on the internal surface and should ideally be between 5-25mm.

  • Where can I get additional assistance on the use of concrete drainage products?

    Additional assistance can be had via the Concrete Pipeline Systems Association, see
