Terra Firma Classic Original Design Range

Original Designs – Original Solutions

The Terra Firma Classic Original Design Range gives unique solutions to solve problem pits for councils and other authorities.

Many legacy designs just don’t cut it in the modern era. Weak and unsafe concrete or cast iron lids simply must be replaced. However finding the right lid for the job can sometimes be a challenge. The challenge gets even more complex when trying to retrofit lids for old, problem pits.

Terra Firma’s standard range of Original Design frames and composite lids are made to meet the specific needs of these unique pits. The Terra Firma Original Design range comes in standard configurations including drop-in, bolt-down, cast-in and precast options as well as ‘Bull-nose’ and ‘Roll-over grate’ options. Every project throws up unique problems requiring unique solutions. Terra Firma’s Original Design range is a result of over 20 years’ experience of working with our clients to solve the challenges of their projects. Our Original Design solutions are a demonstrated example of innovation delivering superior whole of life outcomes.

All Terra Firma Original Design frames can be instantly upgraded to C-Class rating simply by using the corresponding C-Class lid. No frame modification required at all. Another great example of innovation in action.
