Ground investigation, done properly.
PM Sampling is a ground investigation contractor based in Wigan. Since 2015 we've drilled, sampled, tested and logged the ground for projects from a single house extension to a large retail park.

Who we are
Drillers and engineers, one team.
Our team brings together drillers, engineering geologists, geotechnical engineers and geo-environmental engineers. Between them they offer a broad range of site investigation services for most types of development, in both soil and rock.
We work on larger and smaller engineering projects involving contaminated land, highways and roads, tunnels, earthworks, excavations and basements, slope stability, retaining walls, foundations, coal mining stability and natural sinkhole hazards.
Whatever the size of the job, the aim is the same: precise results, gathered safely, without paying for more investigation than the site needs. That's why we match the method to the site, from hand-held window sampling where access is tight, to cable percussion boreholes up to 60m deep where the ground and access allow.
The team
Who you'll be working with.
Four disciplines, working together from the first site visit to the final report.
01Drillers
Qualified to NVQ Level 2 in Land Drilling, running our rigs safely on sites of every kind, even the most challenging locations.
02Engineering geologists
Describing and logging soil and rock as it comes out of the ground, so the record of your site is accurate.
03Geotechnical engineers
Turning logs, in-situ tests and laboratory results into the information your designer needs.
04Geo-environmental engineers
Looking at contamination and ground gas on brownfield and previously developed land.
The ground we investigate for
- House extensions.
- New homes.
- Retail parks.
- Highways.
- Basements.
- Retaining walls.
- Brownfield land.
