DRIVE-IN PIEZOMETERS WP-3400 & SGP-3500 SERIES
Drive-in piezometers, also referred to as push-in piezometers, are designed for installing in soft clays, organic or fine grained cohesionless soils typically with a SPT-N value less than 10. They are available with a CPT fitting or 1” BSP thread.
Depending on the depth and type of soil, they can either be pushed directly into the soil from ground level to the required depth or pushed into the base of a CPT test or drilled borehole.
Installation is carried out by using CPT or conventional drill rods onto which is fitted a special adaptor that fits onto the top of the piezometer allowing it to be pushed to depth and the rods retrieved. Adaptors are available to suit most sizes and thread types of rods used for Cone Penetrometer Testing including R32 and reverse threads.
Alternatively 1” BSP galvanised pipe connected directly onto the top of a piezometer with a 1” BSP thread can be used and is sometimes used as a sacrificial pipe left within the borehole.

BOREHOLE ROD EXTENSOMETER
In stock
The Geosense® GEO-XB2 borehole rod type extensometer range is used to measure and locate settlement, displacement and deformation in soil and rock.
It consists of a reference head and one or more in-hole anchors each of which is placed at a known depth and connected to the reference head by either a rigid or flexible rod running inside a flexible sleeve, which keeps the rod de-bonded from the grout.
STRAIN GAUGE PIEZOMETER SGP-3400 SERIES
In stock
The SGP-3400 Series of strain gauge piezometers are designed for monitoring soil pore pressure or changes in water level and are also suitable for dynamic monitoring such as pumping tests.
They are accurate, highly-reliable and suitable for use in the harsh environments often found within civil engineering including water wells, boreholes, dams, reservoirs, rivers, tanks or any other body of water.
NANO TRIAXIAL TILT SENSOR
In stock
The Nano range uses the same core platform as our other tilt sensors, so it can deliver a similar level of performance and reliability, all in a small and robust enclosure. Nanos have been successfully used in many applications, including:
- Tunnel distortion
- Tunnel heave/settlement
- Embankment slippage (used in conjunction with stake mounts)
- Structural movement
- Rail track heave/settlement
- Rail trackbed cant and twist
TILT BEAM
In stock
The Tilt Beam is a lightweight, rigid aluminium beam that is used in conjunction with a Triaxial Tilt Node, a NanoPlus or a NanoMacro.
The tilt beam has been successfully used in many applications, including:
- Movement monitoring of any structure
- Longitudinal settlement
- Tunnel convergence/divergence
- Lateral displacements
TILT BEAM MEMS
In stock
MEMS Tilt Beams are designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of tilt or differential settlement.
They consist of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised.
