Concrete Repair Solutions for a Gas-Production Plant

When the new management of a gas production facility in Hamilton approached us seeking specifications for a number of concrete repairs required, Tenera conducted an inspection and determined that the project had to be divided into two phases in order to ensure the work would be completed with the highest standard of quality.

Phase 1

Given the extensive scope of work, we established the repair schedule, prioritising the most urgent work. The contractor was instructed to begin work at the truck delivery area, addressing an existing tripping hazard caused by uneven surfaces and sections of the curb with fractured concrete. Crack repair and patching were done in other areas as well. Work type and material specifications were provided to ensure lasting results.

Crack Repair

When a proven repair method and specialised materials are used, monolithic adhesion of 1.95 MPa can be achieved, enabling contractors to effectively fill cracks in any concrete surface, even in wet conditions, restoring them to their original integrity.

Concrete PatchingThrough the utilisation of industrial-grade products, patches as thin as 5 mm can be applied. They are significantly thinner than traditional methods that require a minimum demolition of two inches. This monolithic patching ensures complete restoration of concrete surfaces. The patching process entails three steps: removal of unsound concrete, application of adhesive, and patch installation.

Phase 2

The second phase of repairs consisted of the restoration of the chemical room and the concrete slab at the entrance to the transformer room.

Chemical Room Floor

Prior to coating the chemical room floor, the contractor was instructed to prepare the surface by grinding it for the initial coat. The floor was left to cure overnight, followed by the application of a second coat, with sand broadcast to ensure a non-slip finish.


Transformer Room

Concrete SlabTo achieve complete slab restoration, the contractor did surface grinding and repaired the cracks with an epoxy-based crack filler, applying patches where necessary.
