Earthworks & Soils stabilisation Testing
Soil improvement and soil stabilisation can be used for fills, foundations, subgrade improvement, slope repairs, working platforms, and hardstanding. By adding binders in-situ, you improve the soil’s performance. This method is proven to be both cost-effective and sustainable.
In earthmoving operations, it is essential the materials in use comply with the classification and placement criteria designated in the contract and are tested in compliance with the relevant clause of the British Standard BS 1377. An earthwork’s design is extremely important to a construction, as all the subsequent operations are based on the integrity of the placed materials and rely on the anticipated strength of the operation.
Simtec provide a full range of contamination testing suites accredited to UKAS and MCERTs for soils, waters, and gases through approved external laboratories.
Post-stabilisation testing is also carried out to ensure the finished material meets design and compliance requirements.

Site Quality Control Testing
On-site quality monitoring and control testing is carried out by one of our skilled site technicians and includes:
- Moisture Condition Value (MCV)
- California Bearing Ratio (CBR)
- Plate Bearing Test
Simtec also monitor the binder addition rate and take samples during site treatment for strength testing.
Plate Loading Testing
The plate loading test developed by the US Corp of Engineers is used to assess the in-situ strength of naturally occurring ground for structural purposes or to test the integrity of placed layers of material for compliance purposes.
Stiffness Measurement with the Lightweight Deflectometer (LWD)
The Portable Falling Weight Deflectometer or Lightweight Deflectometer (LWD) is a rapid assessment tool for carriageway layers. For pavement design, it is necessary to know the stiffness of the foundation platform, and this can be quickly achieved using the deflectometer. Giving a direct readout in Megapascals (MPa), this equipment is an invaluable tool for pavement engineering.
A test is carried out by placing the machine over the area and releasing the weight using a trigger. This process is repeated several times and the computer, having collected the geophone data, calculates an average value for the stiffness of the material beneath the plate. The process takes only a few minutes, meaning a large area can be assessed in a short space of time.
This equipment is now accepted by Highways England and appears in the Specification for Highway Works as a tool for the evaluation of highway foundation platforms. The same process can be carried out on existing pavements to gain stiffness information when designing maintenance strategies.
Dynamic Cone Penetrometer Investigation
This method enables stiffness values to be gained from a considerable depth. Software has been developed to convert the cone resistance to a CBR value and present it in a graphical format. This can be invaluable for pavement design, foundation design, and compaction assessment.
