Land Drilling

We supply the necessary ground data with a complete range of reliable land drilling and in-situ testing services, delivered efficiently by our experienced technical teams

RELIABLE AND FOCUSSED SITE DATA

Windowless / Dynamic Sample Boreholes

This popular, mid-range soil investigation technique is delivered using our lightweight, highly mobile rigs, making it ideal for sites with restricted access or sensitive areas.



We use a drop hammer to drive samplers, recovering good quality, undisturbed soil samples in plastic liners, typically to depths of 5-8m. The same rig allows for essential in-situ testing, including Standard Penetration Tests (SPTs) and Dynamic Probing, providing you with reliable strength and depth data for a cost-effective solution.

Dynamic Probing

When you need fast, reliable soil strength data, Dynamic Probing is the ideal technique. Using our mobile rigs, this method employs a drop hammer to quickly drive steel rods into the ground.



We record the blow counts per 100mm drive, which provides a rapid, continuous log of soil strength across your site. This data is highly correlative and is typically used alongside window sampling or boreholes to give you an immediate and cost-effective initial assessment of shallow ground conditions.

Handheld Window Sampling
Where access is a real issue and for working on slopes, the Handheld window sampling equipment is ideal for providing a log of the subsoils. The equipment is light weight and can be carried to the drilling location. 

Sampler tubes of 1-2m length are driven into the ground using a hydraulic or electric breaker using a series of metal extension rods. The sample is then recovered using a set of 12t hydraulic jacks to be logged and sampled by the attending Engineer.

Solutions for restricted sites and slopes

Handheld Window Sampling and Dynamic Probing

When site access is the primary challenge, our handheld window sampling and dynamic probing equipment provides the solution. This kit is lightweight, portable, and can be hand-carried to slopes, basements, or areas completely inaccessible to standard rigs.


Utilising a hydraulic or electric breaker, sampler tubes are driven into the ground via a series of extension rods to depths of 1-2m, providing a reliable log of the subsoils. The samples are then recovered using powerful 12t hydraulic jacks, ensuring the attending Engineer can retrieve and log quality samples even in the tightest locations.


This method delivers the vital data you need without incurring the cost or disruption associated with clearing access for larger machinery.

Deep foundations in soils

Cable Percussive Drilling


This traditional and highly reliable technique is the industry standard for deep investigation in soil strata, offering a typical depth range of up to 40m.


Delivered by robust Cable Percussion rigs, this method uses powerful drop tools to efficiently cut through and bail underlying soils. While it involves a larger operational footprint, it provides the definitive data necessary for critical infrastructure.


Throughout the drilling process, our engineers perform essential in-situ strength tests (like SPTs) and collect undisturbed samples. This method is the clear choice if your project requires a piled or deep foundation, and our team is ready to advise you on whether this is the right approach to de-risk your site

Deep foundations in Rock

Rotary Percussive Drilling

When your site features a mix of both soil and underlying rock, versatile combination rigs are the most efficient solution. These powerful rigs can seamlessly switch between percussive window sampling (Dynamic) for soil investigation and rotary coring for recovering rock cores.


With a depth capability of 40m+, these rigs allow us to collect both dynamic and rotary cored samples in plastic liners, along with performing essential in-situ tests and recovering undisturbed samples.


Though these tracked rigs require a slightly larger operating space than our smallest options, they provide the comprehensive, deep data you need from a single, efficient setup.

Trial Pitting

Mechanically excavated trial pits offer a powerful, quick, and cost-effective way to investigate a large area. This method is exceptionally useful for mid-to-large scale housing developments or any site where extensive lateral coverage is required for a Geo-environmental investigation.


Typically reaching depths of 2-3m, trial pits are perfectly suited for projects utilizing shallow foundations. Crucially, they provide direct visual inspection of the ground and allow for the collection of large soil samples.


We often recommend combining trial pits with window samples or dynamic probe tests. This combination gives you the best of both worlds: broad, visual coverage from the pits, and detailed, quantitative soil strength data from the complementary techniques

Hand excavated trial pits are usually used to uncover buried foundations and structures; these are also a quick and easy way to check the ground conditions in areas which will be used as gardens in a proposed development.
