Allied Exploration & Geotechnics Limited has the ability to tackle any site investigation ranging from one window sampling unit on site for a single day, through to low-headroom cable percussion rigs or restricted access rotary rigs working inside buildings, to multi-rig units on larger contracts, often on heavily contaminated brown field sites and disused former industrial infrastructure. We offer the complete solution to site investigation works with in-house professionals and plant resources to cover everything from investigation design, conducting complex and diverse exploratory hole programmes, UKAS accredited laboratory soil testing and geotechnical/geoenvironmental reporting. Services that fall outside our in-house portfolio are typically project managed and out-sourced using our extensive approved subcontractor list.

Geotechnical & Geo
Environmental Reporting Services

Site operations are backed by strong geotechnical and environmental reporting services using gINT and other commercial software for initial deskstudies to final assessment reports.

Site Investigation Access Considerations

Early contractor involvement on difficult site investigations can make all the difference in selecting the most appropriate and cost effective approach. It is often beneficial to all parties that the technical objectives are fully understood and the correct techniques are choosen from the outset to avoid more costly duplication of the work at a later stage. Why compromise when we offer free and impartial advice which can help you tailor an investigation that is both fit-for-purpose and economical - addressing any geotechnical design risk issues and providing representative ground information that will facilitate the design process.

Overwater Investigation: Drilling & Boring

Overwater investigation on the River Tyne, Newcastle using a floating pontoon platform with spud-legs for stability and anchorage. Operations included cable percussion and rotary coring, with associated sampling (CEFAS sediment analysis) and in situ testing (borehole vane, SPT). We have a long heritage and expertise relating to successfully conducting investigation operation on in-land river systems and near shore environments using cost effective pontoon platforms. Our drilling operatives are competent and fully experienced in these situations.
