Engineering discipline.
Field experience.
Shared values.
BioSqueeze combines subsurface engineering, field operations, biomaterials, government programs and commercialization in one deployment-focused company.
Our values
The principles behind every deployment.
Moving a biological process from the laboratory into critical infrastructure demands more than technical performance. It requires sound judgment, transparent collaboration and respect for the people and environments affected by our work.
Innovation
Continued innovation drives us to expand what biomineralization can accomplish across the built and natural environment.
Environmental responsibility
We work to create a healthier, more resilient planet by using biomineralization to reduce environmental impact, protect groundwater, strengthen soils and extend the life of critical infrastructure across industries.
Work ethic
Our Montana roots shape how we work: stay practical, solve the problem and continue until the job is done.
Success
We define success by solving our clients’ problems safely, reliably and with measurable field results.
Safety-minded
We hold our safety standards high so everyone working in the field goes home safe at night.
Our team
Experienced leadership for a new class of subsurface engineering.
The team has taken biomineralization from scientific insight to hundreds of commercial field deployments—then extended the platform through demanding government programs and new market applications.
