SERVICES
CJ Associates works across all sectors, including transportation, construction, housing, local authorities, utilities and power. We understand that each site comes with its unique set of challenges and constraints. Using a variety of drilling rigs enables us to offer flexible bespoke solutions tailored to each site. Moreover, we operate the longest established laboratory with UKAS accreditation in the West Country, thereby enabling us to offer rapid laboratory scheduling and reporting.
We provide clients with comprehensive reports while maintaining our commitment to follow the latest developments and studies into the mechanics and remediation of soil. Our geotechnical engineers work as a cohesive team: samples are logged on-site, transferred digitally with a testing schedule to the desk-based engineer writing the report. The seamless process delivers laboratory results and final reports promptly. Additionally, we install high-quality ground and groundwater monitoring instrumentation and can provide ongoing on-site monitoring services.
DRILLING SERVICES
All of our drilling rigs are capable of carrying out standard penetration tests. Alongside our rigs and operators, we can access a network of approved drillers and rigs and mobilise quickly. Our drilling rigs are well suited to installing monitoring equipment.
IN-SITU TESTING
An integral aspect of site investigations is a ground investigation, which identifies and classifies the types of soil into different groupings that inform engineering design plans. In-situ testing is an essential part of geotechnical engineering
SITE INVESTIGATIONS
Site investigations are an integral component of an urban development project’s planning stage. Typically, geotechnical teams examine an area’s soil composition and the strength of the soil and rock and various other characteristics that might affect construction safety.
LABORATORY TESTING
CJ Associates run a UKAS accredited soils and materials testing laboratory. The accreditation was initially achieved in 1994.
TRIAL PITTING
Trial pitting is an intrusive method of site investigation used to determine the makeup and composition of near surface deposits as well as providing information on the shallow groundwater regime of a site.
