SJM Ltd was founded in October 1986 by Simon J Martindale to provide window sampling and subsidence investigation services to consultants and engineers throughout the UK.

SJM found that the techniques they were using also suited environmental consultants and Brownfield investigation. We have been used over the past 15 years by many insurance companies, loss adjusters and high profile consultancies and have expanded our services to include low headroom hollow stem auger drilling , stand-pipe installation, mini piling, soil vapour surveys, dynamic probing and concrete coring alongside hand dug trial pits and environmental audits.

The number and range of our customers is an excellent indication of our success in offering satisfaction and service at competitive rates. We are proud that so many of our customers come back to us again and again. Our services are regularly used by many large and well know consultancies.

The majority of our staff have been with us for 10 years and have been trained to a very high standard. Our team of people brings together a wealth of experience that we put to work for our customers benefit.
