We have been involved in the verification of ground gas protection measures for over 20 years and have witnessed the evolution of the industry.

Our dedicated verification team not only provides independent verification in line with CIRIA C735 - Good practice on the testing and verification of protection systems for buildings against hazardous ground gas, but also offers services such as preparation of “Remediation Strategy, Implementation and Verification Plans” based on the guiding principles set out in the relevant British Standard [in this case BS8485:2015 (+A1 2019)].  We also have considerable experience in verification projects ranging from vast commercial warehouses and schools to residential plots and even retrofitted measures.

We offer visual inspection and mechanical stress point testing as standard, however we can also supply/undertake a range of additional integrity testing methods to suit your particular project:

Air Lancing
Dielectric Porosity Testing
Tracer Gas Testing

Our Verification Specialists have over 35 years combined experience and hold industry relevant qualifications such as NVQ4 in Verification of Ground Gas Protection Systems; Specialists in Gas Protection Verification SGPV (GPVS by CL:AIRE) and Technicians in Gas Protection Verification TGPV (GPVS by CL:AIRE).
