Lourensford Industrial Area, Somerset West
My name is Jacobus Theart. I obtained my National Diploma in Civil Engineering in 2009. My career in the construction industry began in 2008 when I joined WBHO Construction—one of the largest construction companies in South Africa. I worked there until 2014, contributing to several high-profile projects including the Greenpoint Stadium, a Valpré bottling plant, a SAB brewery, and the Christiaan Barnard Netcare Hospital.
In 2014, I became an active partner in a steel manufacturing company. After five years, we successfully sold the business, which allowed me to return to my true passion—construction. From 2019 to 2025, I worked with Afriline Civils, where I managed projects for major clients such as Anglo American, Vedanta Zinc International, local municipalities, and private sector clients.
With extensive experience across all phases of construction, I launched JXT Construction Projects with a clear goal in mind: to be that builder—one that both past and potential clients trust, respect, and want to do business with.
Major projects: Greenpoint Stadium, Valpré bottling plant, SAB brewery & Netcare Hospital.

At JXT Construction Projects, building excellence is driven by rigorous, hands-on leadership. Our site managers, Ernst Theart and Angus Gongo, manage and oversee every phase of structural development directly on the ground. Together, they combine years of technical expertise, strict safety protocols, and attention to finish quality—guaranteeing that your build is delivered precisely on schedule and built to endure.
Continuous on-the-ground inspection of foundation trenches, steel reinforcement grids, concrete slump tests, brickwork alignments, and luxury finishes in strict adherence to SANS 10400 building regulations and NHBRC standards.
Daily safety briefings, hazard assessments, structural shoring inspections, strict PPE compliance, and comprehensive site security to safeguard personnel, client property, and surrounding assets throughout the build.
Direct coordination of specialized trades, daily material deliveries, heavy plant equipment deployment, and phased milestones—ensuring rapid turnaround without compromising craftsmanship or durability.
Read transparent feedback from homeowners, property developers, and structural engineers who trusted JXT Construction with their projects across Somerset West and the Western Cape.
"Jacobus and the JXT Construction team delivered exceptional quality on our new residential build. From the ground excavation to the complex second-storey reinforced concrete slab, the engineering precision was world-class. Jacobus is on-site daily, communicates proactively, and keeps the build strictly on schedule and within budget. Highly recommended for any structural or luxury home build!"
"We had severe concrete spalling and rust bleed on our seaside balcony and external support pillars. JXT Construction diagnosed the root cause, excavated the corroded steel, treated it with anti-corrosive primer, and applied high-grade Sika structural repair mortar with weatherproof elastomer coating. The finish is immaculate and structurally sound. Professional, tidy, and transparent pricing!"
"Extending an occupied double-storey home is always stressful, but JXT Construction made the entire process seamless. The team handled municipal engineer inspections, NHBRC registrations, steel beam installations, and roof truss integrations with zero hassle. The site was swept clean every evening. Jacobus is honest, knowledgeable, and reliable."
"We needed heavy-duty reinforced concrete retaining walls and site terracing on a steep slope in Gordon’s Bay. JXT’s civil engineering background really shined through. They handled the micro-excavation, rebar tying, and concrete pump delivery flawlessly without damaging existing paving or garden areas. 5-star service all the way!"
"Removed two load-bearing brick walls to create a modern open-concept kitchen and entertainment lounge. JXT designed and installed the engineered steel RSJ lintels and support columns with laser alignment. The plastering and ceiling integration was seamless—you would never know there were walls there previously. Truly master builders!"
"Jacobus Theart is one of the few builders who genuinely understands soil mechanics and structural tolerances. Our engineer approved the foundation trenches and steel reinforcing on the first inspection without a single correction. Excellent workmanship, reliable crew, and completed ahead of time."
