  • High Rise Residential

    We fully understand the engineering challenges high rise residential buildings pose. The Terrain P.A.P.A. and Pleura System, which negates the need for secondary venting, is one example of the unique products and bespoke solutions we've designed for this sector.


  • High Rise Commercial

    We offer above ground drainage systems and solutions which have been designed to deal with high peak demands of water and waste water, both internally and externally. Our Terrain drainage pipe systems offer technical peace of mind for high rise office and commercial systems in conjunction with innovative water supply products.

  • Healthcare

    From large hospital complexes to individual care homes, our secure, tested drainage pipe and supply systems have been offering designers and installers the products and system solutions they've needed for over half a century. Our range of welded drainage systems provide longevity and leak free solutions.

  • Stadia and Leisure

    Terrain have the trusted technical knowhow to be able to provide innovative water management solutions for high footfall areas and rooftop siphonic drainage systems that allow large roof areas to be drained much quicker than a conventional system.

  • Education

    We understand how schools, universities and colleges need drainage pipe systems and plumbing systems with a specific design approach to ensure they don't encroach on teaching areas and disrupt students.

  • Local Authority

    A number of local authority high rise buildings are now requiring refurbishment due to old, decaying soil stacks which were formed from traditional materials. We can provide a unique live stack replacement solution using pre-fabricated plastic drainage stacks which you can install in real time.

  • Retail and Warehousing

    We understand the key part design plays in creating the right atmosphere for retail therapy. Our siphonic drainage systems allow large roof areas to be drained quickly which means less space is taken up by vertical drainage stacks, making your building more aesthetically pleasing.

    We offer solutions for high footfall areas - from water management solutions to leak free joint integrity for drainage and supply systems. Our siphonic roof drainage is suitable for most industrial buildings with a large, flat roof area, such as warehouses and factories.
