Site Investigation Services
GeoTec Site Investigations provides a complete range of practical ground investigation and site investigation services for consultants, developers, contractors and domestic clients.
Ground Investigation Support for Safer Project Planning
Our services help establish ground conditions, support foundation and drainage design, assess access
constraints, inspect existing structures and provide information required before construction or design
work progresses.
Our services
windowless sampling
Windowless sampling is commonly used to obtain soil samples and ground information from shallow depths. It is suitable for a wide range of site investigation projects and can support geotechnical, environmental and foundation-related assessments.
Restricted Access Windowless Sampling
Restricted access windowless sampling is suitable for sites where standard equipment cannot easily reach. This can include rear gardens, internal areas, tight access routes and constrained development sites.
Dynamic Probing
Dynamic probing is used to assess relative ground resistance and provide useful information about
changes in ground conditions with depth. It can support foundation assessment, ground improvement
checks and general site investigation work.
Hand-Held Window Sampling
Hand-held window sampling provides a practical solution for smaller sites, sensitive locations or areas where access is limited. It is often useful for domestic projects and constrained areas.
BRE 365 Soakage Testing
BRE 365 soakage testing is used to assess whether ground conditions are suitable for soakaway drainage. The results can support drainage design, planning applications and SuDS strategies.
Constant Head Borehole Soakage Testing
Constant head borehole soakage testing can be used to assess infiltration characteristics within boreholes. This can be suitable where deeper infiltration information is required or where trial pit soakaway testing is not appropriate.
Concrete and Tarmac Coring
Concrete and tarmac coring is used to create openings through hardstanding, roads, yards, slabs and paved areas. This allows access for investigation works or provides core samples for assessment.
Hand-Dug Foundation and Inspection Pits
Hand-dug pits are used to expose foundations, inspect ground conditions, identify construction details and investigate areas where mechanical excavation may not be suitable.
Underground Service Inspection Pits
Underground service inspection pits are used to expose and verify buried services, helping reduce risk before excavation, drilling, construction or design work.
On-Site Soil Logging and Sampling
On-site soil logging and sampling provides clear records of ground conditions encountered during investigation works. This information can support design, reporting and further assessment by consultants or engineers.
Structural Opening Up Works
Structural opening up works are used to expose concealed elements of a building or structure. This can
support structural inspections, refurbishment planning and design decisions.
Our services
Our site investigation services provide the information needed to understand ground conditions, assess site constraints and support confident planning, design and construction decisions.

Supporting consultants
and domestic clients
We understand that every site is different. Some projects require efficient access for drilling equipment, while others need careful hand excavation, restricted access solutions or small-scale domestic investigation works.
Our team can assist with both consultancy-led investigation programmes and direct enquiries from homeowners who need practical site information for extensions, drainage, foundations or structural works.
