Expert for Civils & Green Infrastructure

Clark McAllister

Sales Director, Polypipe Civils


Clark began his 40-year career in construction as a mechanical engineer working for Drayton Engineering in London where he specialised in the development and installation of control systems for the heating industry.  In 1993 Clark joined Polypipe as Area Manager.  Progressing through the organisation as it expanded, he reached the position of Divisional Sales Director for Polypipe Building Products before moving to the Civils & Green Urbanisation business in 2020.  A keen golfer and passionate Glasgow Rangers fan, Clark develops, oversees and supports the implementation of the company’s nationwide commercial strategy from its two principal manufacturing sites in Horncastle and Loughborough.


Founded in 1980, Polypipe is one of Europe’s largest manufacturers of piping systems, water and climate management systems, delivering engineered solutions that enable a sustainable built environment.

The development of Green Urbanisation introduces a new generation of techniques that optimise urban green spaces through an extended, fully integrated, sustainable water management network. This includes the provision of hybrid water management solutions that combine green assets such as blue/green roofs, gardens and trees with smart water infrastructure within any urban environment. The benefits are multiple: greater resilience to flooding and drought, increased biodiversity, lowering of the heat island effect, more green spaces and amenities, better air quality, and improved health and wellbeing.

Polypipe Civils & Green Urbanisation is part of Polypipe Group plc and operates two UK manufacturing centres: Loughborough and Horncastle. With products focused at specific applications across all construction sectors including residential, highways, rail and power, each range has been developed around optimised use of recycled materials. The company currently transforms over 16,000 tonnes of plastic waste each year in the manufacture of its products.

Polypipe Civils Comment: Q1 2022

Through the first quarter of 2022, we saw a strong return after the much needed Christmas break. January and February were extremely buoyant, despite the continuing pressures on material supply and accelerating cost-inflationary pressures being felt across the wider economy.

We began to see a change through March. The material supply situation began to ease a little but, driven-on by the situation in Ukraine, price rises became the dominant factor influencing market behaviour and strategic decision making.

Nevertheless, the outlook remained positive through early March with strong quotation activity. As we moved towards April there were early signs of project delays across the majority of construction sectors with the exception of infrastructure, with the likes of HS2 and high-speed communication networks continuing to forge ahead.

Today, quote levels have stayed positive, but the underlying uncertainty resulting from the broader economic situation makes short to medium term forecasting extremely difficult.

Wage inflation is affecting all businesses, not just in construction, and adding further cost-complexity, the industry is struggling to address the continuing issue of skills shortages. A high percentage of the UK’s construction workforce is within five to ten years of retiring and the industry urgently needs to attract large numbers of young men, and women in particular, who see a long term future in construction. As we all step up a gear and change to meet the considerable challenges of climate change and sustainable resource management, it is imperative that innovations such as Green Urbanisation showcase
the potential for exciting, long-term careers.

Finally, the impact of the new regulatory requirements brought in by the Environment Act are beginning to be felt. With developers now being asked to provide greater detail on issues such as biodiversity-net-gain and nutrient neutrality, projects will potentially be subject to further time pressures as local authorities and utilities consider proposals against a far more rigorous sustainability-driven legislative agenda.
