How to choose

For permeability, the Constant Head Permeability Apparatus suits coarse grained soils such as sands and gravel, while the Falling Head Permeability Apparatus is the option for fine grained clay-like or silty soils; both take particles up to 10mm.
For field density, the Sand Pouring Cylinder is used for layers not exceeding 50cm, the Core Cutter comes in 100 x 130 mm and 150 x 180 mm versions, and the Balloon Density Apparatus uses a 1596 ml graduated cylinder but does not suit very soft soil.
For shear strength, the Direct Shear Test Apparatus has 12 electrically driven strain rates, the Laboratory Vane Shear Apparatus (Motorised) turns at 1/60 R.P.M. with four springs, and the Unconfined Compression Tester (Motorised) has a 5000kg screw frame.
For quick field checks, the Pocket Penetrometers read 0 to 1000 kPa with three tip sizes, the Load Ring Penetrometer has a 1 kN load ring and 30° cone, and the Proctor Penetrometer reads 0 to 55 kg with nine interchangeable needles.
For bearing capacity, the Plate Load Bearing Test Apparatus comes as a 200 kN set with 300 mm and 450 mm plates or a 500 kN set with 600 mm and 760 mm plates.

Frequently asked questions

What are the Proctor Compaction Test Apparatus specifications?

The hammer is 50mm in diameter and 2.5Kg in weight with a 300mm drop, and the compaction mould is 100mm by 127mm. It is used to find the relationship between soil moisture content and compacted dry density.

What is in the Plastic Limit Set?

One each of a 15 cm flexible spatula, a set of 6 moisture containers, a 20cm x 15cm glass plate with round ends, a 150mm porcelain basin, a 500ml plastic wash bottle and a 3mm dia x 150mm brass or stainless steel rod.

How does the Soil Cone Penetrometer find the liquid limit?

The moisture content at a given depth of cone penetration is taken as the liquid limit. It has a stainless steel cone 35mm long with a 30° angle, a 55mm x 40mm test cup, a digital timer and a 220V supply.
