  • Do you recommend surrounding pre-cast concrete manholes with in-situ concrete?

    Concrete surrounds to manholes are not always necessary in the majority of situations. However if the sewer is to be adopted, this may be a requirement.

  • 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.

  • 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 standard position of the access opening in cover slabs?

    The standard access position is 150mm in from the chamber wall below (measured from centre of nearest access edge to inside of chamber wall below). Other positions/access sizes/multiple access slabs can be made to order.
