Tunnel Business MagazineGrouting in Support of Tunnel Construction, April 2007. Pacific International Grout Company setting new standards for cementing technology in the underground construction industry.


SAK has had a subcontractor relationship on numerous civil construction projects throughout the United States. We have found Pacific International Grout Company’s performance to be professional, proficient, and exemplary.

In addition to the successful projects that Pacific International Grout has completed for our company, in my opinion, they are one of the undergrounds industry’s best specialty subcontractors to have had the pleasure of dealing with.

– K.C. Hildenbrand, P.E., Project Manager, SAK Construction

Facing the prospect of undue scrutiny brought about by the lack of performance of two prior subcontractors, I was able to discuss the situation and negotiate a deal with Pacific International Grout over the phone late on a Friday afternoon. As promised, equipment was on the road the following Monday morning. By the end of the week the equipment was in place and our first pour was on Saturday, with results that met all the project criteria and specifications and have not varied since, with approximately 25,000 to 30,000 yards in place to date.

I would not hesitate for a moment to recommend your firm to any prospective client. Further, Pacific International Grout Co. will definitely be the contractor of choice for any future projects involving LDCF.
