Over 30 years of experience

Testing, quality assurance, and expert reports for the environment, building materials, and flooring.

Operating Globally

Audits, field testing, and certifications for national and international projects.

Everything from a single source

From site investigations to laboratory and field testing, through to final certification.

Independent & objective

Tests, expert reports, and quality assurance in accordance with recognized standards and international regulations.

Expertise that builds trust

Based in Osnabrück, LLS has been one of the leading independent testing and expert institutes for more than four decades in the fields of site investigations, building materials testing, environmental analysis, and sports surface materials.

Our clients include municipalities, engineering and planning firms, construction companies, industrial enterprises, sports associations, system manufacturers, and public sector clients both in Germany and abroad.

As an independent testing institute, we provide a solid foundation for technical, economic, and legal decisions. Our investigations, expert opinions, and test reports help building owners and planners implement projects safely, economically, and sustainably.

Our Philosophy

Technical decisions should be based on verifiable facts.

That is why we see ourselves not merely as a testing laboratory, but as an independent partner for quality assurance, damage assessment, and technical consulting.

Our goal is to identify risks early on and develop sustainable solutions through objective investigations, modern testing technology, and many years of experience.

Neutrality, technical expertise, and reliability are at the heart of our daily work.

We support projects from the initial concept through to successful completion and offer all services under one roof.

Our range of services includes, among other things:

• Environmental and soil analysis
• Site investigations and geotechnical engineering
• Building materials testing and analysis
• Sampling by our own specialized staff

Close collaboration among our departments ensures streamlined communication and consistent quality assurance throughout the entire project.

Quality begins before the first sample

Reliable laboratory analysis requires proper sampling.

That’s why, upon request, we handle all sampling with our own specialized staff—from soil and building material samples to asphalt, synthetic turf, or environmental samples.

Complemented by modern laboratory analysis, field tests, and independent expert reports, our clients receive reliable results and a single point of contact for all project phases.

Regular audits, state-of-the-art testing technology, and ongoing professional development ensure reliable results and the highest quality standards.

Our Commitment

Every project is different.

That is why we do not develop standard solutions, but rather provide our clients with individualized support—from the initial site investigation through laboratory and field testing to the final certification or an independent expert opinion.

Our goal is to present technical relationships in an understandable way, identify risks early on, and provide our clients with a sound basis for decision-making.
