As a leading soil science consultancy our services are not limited to projects in the UK. We support all elements of land development, management and regeneration, from the initial planning stages, outline and detailed design, through to construction and aftercare, with many of our core services applicable to landscaping projects across the globe.
TOHA has been involved in a number of international projects where our expertise has been applied to a wide range of scenarios across vastly different environments. Some of the countries we have covered include Spain, France, Netherlands, Gibraltar, Azerbaijan, Jordan, U.A.E, Qatar, Oman, India, Singapore, Vietnam and Indonesia. The projects have included commercial and residential developments, city parks, major construction projects and specialist landscape schemes.
Our involvement often starts at early stage planning and continues through construction to final landscape validation.
Our services include:
- Soil Survey and Site Investigation – for the evaluation and quantification of any project site’s soil resources, including residential and commercial developments, highway construction, new schools, parks, pipeline installations, and agricultural land improvement.
- Soil Testing Services – sampling and testing service to assess the quality of soils and soil ameliorants used within the landscape sectors.
- Soil Handling and Management Strategy – sets out clear guidance on the methods of recovering, storing and re-using soils whilst minimising any loss in quality and function.
- Design and Specification Technical Support – technical support for design and specification of soils, drainage, tree pits and specialist landscape areas.
- Site Inspections and Monitoring Services – to confirm that the soil conditions are compliant with the specification/design or to identify non-compliances that need to be addressed.
- Topsoil Manufacture – if required we can assist in developing project-specific soil manufacture blends and techniques based on the project’s requirements, with a focus on local resource utilisation.
- Habitat Creation and Management – assisting landscape architects and ecologists to understand, manage and make best use of their on-site resources and/or advise on suitable imported materials to suit the site, design and project aspirations.
