Ground Investigation
At Streval, we have a great amount of experience working in ground investigation. We work closely with our structural engineers to help our clients understand or analyse the ground in order to confirm whether changes to the loading of the ground bearing slab can be undertaken safely. Ground investigation is a hugely important step in the development process. For developers, ground investigation allows for critical information to be obtained which indicates whether designs can be developed and brought to life. Ground assessment also helps to identify potential risks and prevents development on hazardous ground. We can work closely with the client to understand their requirements. This way, expectations can not only be met but, hopefully, exceeded. Our ground investigation services are headed by an experienced and knowledgeable team of surveyors, assessors and engineers.
Soil Investigation
When completing soil investigation our team relies on a number of methods, some of which include: plate load testing, California bearing ratio testing (CBRs), shear vane tests or dynamic cone penetrometer. We understand the importance of soil investigation and ground investigation, so we ensure our methods incorporate the latest technology and relevant knowledge. We continually look to develop our knowledge about our field, and this is no different for soil investigation. In order for construction projects to take place, an accurate summary of the ground conditions is absolutely vital. This helps developers actualise designs in the safest and quickest way possible. If a client enlists our help to complete soil investigation and ground investigation, we will use every resource available to us to ensure we give you a comprehensive and accurate assessment of the ground. For more information on our ground investigation and soil investigation services, contact us today. One of our team will get back to you at the earliest available opportunity, and will be happy to discuss your project ambitions in greater depth.

Our Soil & Ground Investigation Services
-
DCP Testing
The DCP uses a 6.8 kg steel mass falling 50.8 cm that strikes the anvil to cause penetration of a 3.8 cm diameter cone (45° vertex angle) that has been seated in the bottom of a hand augered hole.

California Bearing
We offer on site plate bearing/CBR testing for clients wanting to evaluate or design flexible pavement components and for other applications like unsurfaced roads.

Plate Load
Plate load test is a field test, which is performed to determine the ultimate bearing capacity of soil and the probable settlement under a given load.

Ground Bearing
We receive many enquiries for projects where the ground bearing capacity of a slab needs evaluating due to refurbishment or changes to the structure and loading profile on the ground bearing slab.

Vane Shear
The shear vane test is a method of measuring the undrained shear strength of a cohesive soil.
