Our Services

GeoSolutions provides specialist geotechnical services to assist you with your building project. You may need to provide a Geotech report to accompany your application for resource consent for a subdivision or would like a foundation assessment for a new cellphone tower. We will help you establish an appropriate and cost-effective investigation for your project and then walk you through the process through to consent application. We usually need to double check the plans before application, may need to answer questions during the consent application and will almost certainly need to check the ground conditions during construction.
