Synthetic field and hard surface playing facilities
Ground Science are market leaders and innovators in the engineering of synthetic playing fields and facilities with unique and cost effect designs.
The long-term performance of a synthetic playing surface, relies upon good sound engineering. The pavement needs to be designed based on the performance criteria and is dependent on subsurface conditions at the site.
The process should commence with a geotechnical investigation to identify potential design issues. The variability of sites including; reactive/swelling soils, weak soils, old landfill sites, deep under compacted fill zones or sites requiring fill placement are sites which may have elevated risks.
A Geotechnical investigation and pavement design are required to mitigate the construction and longer-term risks associated with this type of asset. We are leading the way in innovative designs and risk management. Our extensive portfolio of projects is testament to our expertise in this field.
