Laurence Mowatt and his redoubtable mount, Callaho Lorenzo, kicked off the year in style, taking top honours in the 1.40m Two-Phase at the Presidents Cup in Krugersdorp last week.

A fantastic result and a proud moment all around.

At Spec-Con, we’re starting the year with that same energy - focused, driven, and ready for what’s ahead. But amidst the deadlines and pressure, it’s just as important to keep that balance.

Here’s to strong starts, great partnerships, and a year full of momentum.

An Empty Reservoir Can Still Be Filled With Hope.

An empty reservoir is a powerful reminder of the scale, skill, and effort behind the infrastructure we take for granted.

Every time a tap is opened, decades of engineering quietly do their work.

South Africa is at a turning point.
Much of our water infrastructure is aging and in urgent need of repair and maintenance if we are to meet the needs of both current and future generations.

With decades of hands-on experience in concrete repair and rehabilitation, Spec-Con Engineering is well positioned to restore and extend the life of these critical assets — helping ensure water security where it matters most.

Spec-Con Engineering is officially back and open for business!

We’re ready to service our clients and deliver trusted concrete repair solutions in the year ahead. Wishing everyone a prosperous and successful New Year.

Did you know we can check the strength of concrete without breaking it? 👀🛠️

At Spec-con, we use a Schmidt Hammer to get quick insight into how strong and dense concrete is.

Here’s what we do:
👉 The hammer is pressed against the surface.
👉 A spring-loaded impact is released.
👉 The rebound reading helps us estimate the hardness and overall condition of the concrete.

This test helps us:
✔ Pick up weak or deteriorated areas
✔ Check if concrete was cured properly
✔ Assess older structures
✔ Provide fast, on-site results

Because Schmidt Hammer readings are not 100% accurate on their own, we often pair them with concrete coring and laboratory testing. This ensures we provide the most reliable assessment possible — combining quick non-destructive testing with precise strength results.

Whether you need a condition check or a full concrete assessment, Spec-con has the tools and expertise to do it right. 🏗️💬

Huge congratulations to Laurence Mowatt, Director at Spec-con, for being named one of the winners of the Mentors Cup! 🏆🐴

A massive thank you to Kumusha Equestrian for hosting such a fantastic event.
Your support made it possible for Highveld Horse Care Unit to benefit from this initiative — a cause that is very close to our hearts. 💛

We’re incredibly proud to see Spec-con represented in an event that not only celebrates skill and dedication but also uplifts such an important charity in our community.

Well done, Laurence, you’ve made us proud! 👏✨

🧱 Why Does Concrete Turn Pink When We Spray It?

In our last post, we spoke about carbonation in concrete; carbon dioxide from the air reacts with the concrete over time, lowering its pH and putting the reinforcing steel at risk of corrosion.
To check for this, we spray a chemical called phenolphthalein.

✨ When the concrete turns pink, that’s a good sign - it means the concrete is still healthy and alkaline, and your steel is well protected.
⚪ If it stays colourless, that means carbonation has occurred, and that section could be at risk of corrosion.

It’s a simple test that tells us a lot about what’s happening beneath the surface, helping us plan the right repairs before any serious damage occurs.

🧱 What Is Carbonation in Concrete?

Carbonation happens when carbon dioxide (CO₂) from the air seeps into concrete and reacts with materials inside it. Over time, this lowers the concrete’s natural protection around the steel inside.

Once the steel is exposed, moisture and oxygen cause rust — which expands, cracks the concrete, and weakens the structure.

This happens faster in high-pollution areas like Johannesburg, where CO₂ levels are higher.

At Spec-Con, we perform carbonation depth testing to see how far the process has gone and determine if repairs or protective coatings are needed.

We’re currently working on National Highway bridges, helping ensure these vital structures stay safe, strong, and built to last. 💪

We’re celebrating a proud moment for the Spec-con Engineering family! 👏

Our Director, Laurence Mowatt, represented us at the Toyota 2025 SA Derby — South Africa’s biggest horse show, showcasing the best in showjumping, dressage, and showing. 🐎✨
Laurence achieved 1st place in the 1.5m A2 competition (2nd qualifier) and finished an impressive 4th overall in the showjumping category!

A huge congratulations also goes to his dedicated groom, Petros, who received a prestigious long service award 🏅 a true testament to his hard work and commitment over the years.

We couldn’t be prouder of both Laurence and Petros for their dedication, passion, and for carrying the Spec-con name with pride, both in the engineering world and in the arena. 💪🐴
