Cornerstone is based in Willis, Texas, about an hour north of Houston.  We have recent experience on NGL transmission lines and natural gas gathering lines in East Texas, South Texas, West Texas, Louisiana, Utah, and Colorado.  We employ personnel who have a positive reputation in the industry based upon their character, work ethic, and team player ability as well as for their knowledge and experience.

We are experienced managing construction of natural gas gathering pipelines up to 24" diameter and inspection of DOT regulated interstate gas transportation pipelines up to 48".

Every service we provide to you, the pipeline owner, is performed by our people as if your pipeline were our very own.  Our name reflects not just our attitudes but the very culture of our company.  Cornerstone is defined as “something that is essential, indispensable, or basic; the foundation on which something is constructed”.  Two definitions of integrity apply here.  First, “moral soundness; honesty; freedom from corrupting influence or motive”.  Second, “a sound, unimpaired, or perfect condition”.  It is essential that your pipeline be built on the cornerstone of moral soundness and honesty, free from corrupting influences, in order that the resulting product be one that is sound, unimpaired, and financially productive for many years to come.  The integrity of your pipeline begins with the integrity of the people who build it, and we are those people. 

Although other companies claim to offer similar services, we have a reputation in the industry of completing pipeline construction projects on time and within budget.  Please call us and experience the benefits of building your next pipeline with people of integrity.

Thank you for your interest in our company.
