Sustainable engineering using ground screws

'We inspire and are inspired by safe and sustainable engineering.' At KITE, we are all about protecting the environment through collaborative and sustainable engineering. We use methods of sustainable foundations to fit and install our KITE Step system.

Ground screws are an environmentally friendly alternative method to using concrete when installing or building foundations in your projects. According to RADIX, the difference between concrete and ground screws are:


Based on a 0.216m3 block

Ground Screw

Based on a 76mm x 1550mm screw

• Contains 77.33kg of embodied carbon (CO2e)

• Requires extensive excavations which damage land and natural habitats.

• Removal of spoils increases truck movements and carbon footprint.

• Compounds in cement compromise soil quality

• Removal is labour-intensive, time-consuming, and costly

• Contains 24.05kg of embodied carbon (CO2e)

• Installed without digging and impacting land, natural habitats, or soil quality.

• Removed rapidly without damage or trace

There are significant time, cost, and environmental savings to be gained from using ground screws. At KITE, we have used them for various projects, including the M6 toll in the Highways sector, ensuring that we are contributing to the greater good through a sustainable environment.

With scrutiny on the construction industry for its sustainability credentials, KITE Projects is continuously developing sustainable approaches to its services, and environmentally friendly attributes to its products - such the long-life span of the materials it uses, the minimisation of mixed concrete on site, are just a few of the things that bring KITE Projects’ environmental focus to life.

Our innovative approach to sustainable engineering also includes the consideration of whole-life project investment; we have discovered that engineering for a 50-year design life will often be significantly more sustainable than short life solutions. Both carbon and financial costs of replacing shorter life span products should be the collaborative focus of our industry as it is well within our responsibility to consider the effects of short-term decisions.
