The Ground Crack Inducer is designed for inducing cracks from the bottom of the slab. It is very easy to install and will ensure a positive break through the joint.
Ground Crack Inducer is an inverted V-shaped durable PVC extrusion. It is positioned on the sub-grade before the dowel cradles are placed. It produces a weakening in the slab that initiates a crack in the slab from the bottom up.
Not recommended in slabs less than 150mm thick.
KEY FEATURES
- Induces cracks from the ground up
- Eliminiates uncertainty of cracks parallel to the joint
- Ensures positive breaks through joint
- Available in convenient 3 metre lengths
- Available in 25 and 55mm heights

Our concrete fibre slabs have been around longer than our competitors have been in business. Some of the many benefits of having Lesa Systems/Canzac as a single source supplier: Design assistance: Involvement in the design and documentation from the very beginning of the project - before the working drawings are commenced (EDI). At Connolly Key Joint, we have been manufacturing patented concrete jointing systems since the 1980s. Focused on maintaining growth through an extensive research and development program, we regularly introduce new and innovative products. Our jointing systems (expansion joints, contraction joints, control joints, construction joints) are designed, tested and engineered to reduce construction.

At Lesa Systems Ltd, we want to help engineers, designers, developers and contractors to mitigate against any risk in their concrete construction project.
Crucial in achieving this is aligning your business with a single source partner. One that is trusted, reputable, and has extensive experience with concrete and the construction process across all types of projects, as well as having extensive knowledge of the inevitable issues encountered with poorly designed and constructed slabs on grade.

Lesa Systems Ltd and Canzac Limited have both been in business for 30 years, offering 60 years of combined industry experience. We are the 'go to' company for engineers and contractors as we know what works and we know what doesn't.

Harder Than Concrete - As told to Hugh de Lacy
Harder Than Concrete tells of the struggles founders Lance and Carolyn Canute (CC) encounter in their pursuit to establish and expand Canzac.
It recounts the unconventional path of a young, budding kiwi entrepreneur, who leaves school at 15 and his home at 18 to travel abroad. Along the way, an unlikely friendship ignites a lifelong passion within the construction industry and just as everything seems to be going to plan, life takes an unexpected turn.
Returning to New Zealand in a bleak job market, he tries his hand as a fast-food business owner, only to find that even the world of fast food has its critics. With little interest in improving his cooking, he decides to shut the business, but not before realising that he had won over one customer, a shy, unassuming girl who eventually shows what she’s made of when she asks him out. It’s not long before her loyalty and quiet determination is put to the test as they set up house, start some questionable sideline businesses and spend their entire savings on some Super-Tie formwork systems. Supported only by her medical practice wages they anxiously await for the orders to roll in. From product lines, upsizing and company takeovers, would these risks pay off and just how long would it take this concrete rebel with a cause?
