Concrete jacking pipes have become a fundamental solution for underground infrastructure thanks to their trenchless installation. But behind every high-quality pipe lies a precise technical process, and it all starts with a good mold.
In this article, we show you step by step how a pipe jack is made and why the mold is the heart of the process.
How is a concrete jack made?
🧱 1. Preparing the mold
How is a concrete jack made? The process begins with the proper preparation and assembly of the mold . At Industrias Relente, each mold is composed of:
Core: defines the internal diameter of the tube.
Outer shell: gives shape to the cylindrical exterior.
Support rings: ensure stability and weight distribution.
Base table: supports the entire assembly during pouring.
Hydraulic or mechanical closing system: ensures a perfect seal.
Cleaning and greasing the mold before each use is essential to prevent sticking and defects.
🏗️ 2. Pouring the concrete
Once the mold is closed, the concrete is carefully poured , with a controlled dosage to ensure:
Adequate structural resistance.
Fluidity for complete filling.
Uniform compaction without bubbles or cracks.
Our molds can be fitted with vibrating cores , which significantly improve compaction and reduce surface defects.
🔄 3. Vibration and compaction
This step is essential. Thanks to the built-in vibrators, the concrete is properly compacted around the core, eliminating voids and ensuring a dense and strong structure.
A good mold allows vibration to be transmitted evenly, without damaging the equipment or deforming the part.
⏳ 4. Setting and removing the tube
After the initial setting, the tube must be carefully removed . This is where good mold design makes the difference.
At Industrias Relente, our molds are designed for:
Facilitate extraction without damaging the tube .
Allow for quick and safe opening.
Optimize production times.
✅ 5. Quality control
Each tube is checked to verify:
Exact dimensions (minimum tolerances).
Absence of cracks or defects.
Uniformity in surface finish.
The use of a precision mold drastically reduces errors and guarantees a reliable result from day one.
🔧 Why does choosing a good mold make a difference?
Longer mold life.
Faster, uninterrupted production.
Higher quality pipes, ready to be driven without adjustments.
Savings in production and repair costs.
Bottom line: A good mold doesn't just shape the tube, it shapes the success of your project.
