Why clients work with the Toureen Group

Toureen Group are construction & contracting specialists and one of the biggest benefits of contracting with any of the divisions, is that clients automatically access the Group's wider, in-house expertise. This is particularly beneficial when unexpected project complications arise. Clients have noted that unlike working with a single discipline contractor:

  • value engineering solutions are more innovative because of the influence and exposure to different sectors,
  • construction programmes avoid delay through more resilience to unforeseen challenges and complications,
  • plant and material purchasing costs are more competitive due to the Toureen Group's greater buying power.

We have a varied range of specialities from groundworks and civil engineering to reinforced concrete structures, reinforced concrete basements,  de-watering, temporary works, piling and solutions for restricted site access in cities such as London.
