SPEIGHT DRILLING LTD

 

 

environmental investigation drilling

Environmental drilling is used to investigate, assess and monitor the quality of groundwater and soils and determine the source or extent of pollution problems. Obtaining accurate data is essential to evaluating our environment and for developing solutions to mitigate potential adverse effects.

water bores & ground water Exploration

Groundwater is essential for everyday life. Speight Drilling offer an extensive range of groundwater-related services to help investigate, test and developed sources to support hydrological assessments for aquifer delineation, drinking water supply (waterbores), dewatering requirements and geotechnical investigations.

CONSTRUCTION SERVICES

Piling forms the very basis of many construction projects. Ground anchors are a versatile form of ground support. Dewatering involves drawing-down (controlling) groundwater levels in excavations to allow construction works to proceed.

 

MINERAL EXPLORATION

Speight Drilling have a wide range of experience in mineral exploration drilling, specificaly across the West Coast, Central Otago and Macreas mining areas.

GEOTECHNICAL DRILLING

Obtaining high-quality, representative information is critical to understanding the potential interaction between built structures and the ground. Speight Drilling provide accurate and efficient drilling and testing solutions, enabling you to determine soil and rock characteristics for your project.

 

CPT TESTING

The main purpose of CPT (CPTU) testing is to identify subsurface conditions: classify soil, detect layers and measure strength, determine deformation characteristics and the permeability of foundation soils.

DOWN HOLE LOGGING

We have our own suite of downhole geophysics tools and equipment, enabling us to obtain high resolution images of the borehole wales for an accurate assessment of in-situ conditions. Outputs from logging can include the 3D logs, structural rock data, high-resolution imagery and more.

 


Dewatering

Dewatering involves controlling ground water, by pumping  water to lower ground water levels in the vicinity of the excavation. In order to construct a building, dewatering has to be done by laying pumps at various junctions.

 

BLASTING

Speight Drilling use a non-detonating chemical compound enclosed in a cartridge, which reacts very quickly when ignited to produce high volumes of harmless gas, mainly consisting of nitrogen, carbon dioxide and steam.

 

 

 

 

OFFAL AND SOAKAGE HOLES

Also referred to as dead holes, offal holes are commonly used on farms to dispose of dead stock, home kill waste and rubbish in a hygienic way or as a long-drop. Soak holes are mostly used to dispose of wastewater. They were most common before stormwater systems were introduced and still provide a great alternative for those that don’t want to reuse their wastewater without causing too much harm to the environment.
