Celtest provides professional quality materials testing and consultancy services for UK and international construction & civil engineering organisations.


Here at Celtest we undertake UKAS-accredited site sampling and testing, as well as laboratory testing, on a range of materials including aggregates, bitumen, soil, natural stone and concrete. Our diamond drilling, sawing, and controlled demolition services complement testing, giving customers an effective solution from one supplier or one point of contact.  We also help organisations develop management systems to meet international standards.
