Ensuring a solid foundation

PB uses innovative techniques to improve the ground itself—so that contaminated, swampy or seismically sensitive soils can be rendered suitable for building structures of any kind. Our approach ranges from mini- and micro-piles in access-restricted situations to larger-diameter caissons and gravity-type foundations.

With new, cost-effective and environmentally sound methods, we're providing solutions to our clients' challenges.
