In-situ and On Site testing

As well as our in house Soils Testing, we also carry out on site in-situ testing. Please contact us for more information about the following tests and prices. We are UKAS accredited on in-situ CBR tests, Plate loading tests, In-situ Density tests and DCP (Dynamic Cone Penetrometer) tests.

Plate Bearing Test 

 

The test is carried out by the method described in BS1377:1990 Part 9.4.1

 Before any test is undertaken it’s our general policy to liase with the client to establish their requirements for the proposed project.

The plate bearing test method is used to evaluate the ultimate bearing capacity, the shear strength and deformation parameters of the soil beneath the plate, without entailing sample disturbance.

 

 

In-situ density test (sand replacement method)

 

Small Pouring Cylinder Method:

 

This method covers the determination in-situ of the density of natural or compacted fine and medium grained soils for which 115mm diameter sand pouring cylinder is used in conjuction with replacement sand. The small pouring cylinder method is applicable to layers not exceeding 150mm in thickness.

 

Large Pouring Cylinder Method:

 

For soil containing coarse grained particles and for layers between 150mm to 250mm in thickness the large pouring cylinder method is used.

 

 

CBR Test 

 

The test is carried out by the method described in test

 

BS 1377:1990 clauses Part 9.4.3. Before any test is undertaken it’s our general policy to liase with the client to establish their requirements for the proposed project. The CBR method of flexible pavement design is essentially an empirical method in which design curve is used to estimate pavement thickness appropriate to the CBR value of the soil.

 

 

Dynamic Cone Penetrometer (TRL Handheld Operation)

 

The Dynamic Cone Penetrometer (DCP) is used for the rapid measurement of the in-situ strength of existing flexible pavements constructed with unbound materials.

 

Measurements can be made down to a depth of 800mm of to a maximum depth of 1500mm by adding an extension rod.
