Welcome to Terra-petra
Terra-Petra has been in the environmental engineering industry for over 20 years, with many successful projects to lean on. The company started its operations focusing on the Los Angeles market to address the local “methane concerns” that quickly became a big issue. Our in-house experts were a big part of the team that developed the local Los Angeles Methane Code.
Our team enters every project with a “safety first” mindset and philosophy. Having undergone extensive safety training programs to include the 40 hour Hazardous Waste Emergency Operations and Emergency Response (HAZWOPER) training, we are proud to say that we work with zero injuries in the field.
Terra-Petra’s expertise has always involved the ability to provide exceptional solutions for methane related issues, including soil gas investigations to determine level of risk. We are adept at recommending the right mitigation strategy and designing the right mitigation system to fit the client’s needs as well as providing the necessary inspections to ensure compliance and system integrity. Over the last ten years in particular, Terra-Petra has become to be recognized as the leading expert in methane and soil gas arena. As methane experts, we’ve also become experts at below grade waterproofing and drainage, having launched our sister-company Building Waterproofing Experts in 2010.
