Indrek Uusalu
Indrek Uusalu is an industrial entrepreneur focused on physics-based concrete engineering and long-life underground infrastructure.
His work centers on controlled cracking, material behavior, and structural performance to reduce lifecycle CO₂ emissions — not through offsets, but through structural longevity and measurable durability.
The company delivers scalable solutions for cities, coastal environments, and climate-resilient construction. Indrek’s focus is execution: turning engineering principles into manufacturable systems designed for decades of service life.
"You don’t fight physics.
You design with it."
Indrek Uusalu
CEO of Primostar Group
Indrek’s role is to translate engineering principles into scalable industrial systems — aligning product design, manufacturing logic, and long-term capital allocation. He ensures that technical decisions are not made in isolation, but are integrated into a broader industrial framework where performance, repeatability, and cost efficiency are structurally connected.
His work centers on creating coherence between how a product is engineered, how it is manufactured at scale, and how capital is deployed to support sustainable growth. This means structuring development processes so that design intent, production capability, and investment strategy reinforce each other over time, rather than operate as separate tracks.
Primostar Group is a green technology and construction solutions company with over 25 years of experience in helping builders create watertight, durable, and energy-efficient structures. The company delivers comprehensive waterproofing and construction material systems, covering the entire building envelope — from foundations to roofs.
At the core of Primostar’s expertise is its membrane-free “white tank” system, an environmentally responsible solution designed for the internal waterproofing of underground reinforced concrete structures. Unlike traditional membrane-based approaches, this system integrates waterproofing directly into the concrete structure itself, ensuring long-term performance and structural integrity. One of its key components is patented in three countries, reflecting the company’s commitment to innovation and technical advancement.
The white tank solution significantly reduces material consumption — in some applications by up to eight times — offering a smarter, more resource-efficient method of construction. By minimizing additional layers and simplifying installation, Primostar contributes to reduced environmental impact while maintaining superior durability and performance.
Most of the company’s materials are of German quality standard, selected for reliability, precision, and long service life. Each solution is supported by professional consultation and detailed installation guidance, ensuring that execution on site matches the intended engineering performance.
Primostar works closely with builders, developers, architects, and construction professionals to deliver robust and future-proof structures. Its systems are designed to withstand groundwater pressure, harsh environmental conditions, and long operational lifecycles without compromising efficiency.
Through a combination of engineering expertise, patented innovation, and execution-driven support, Primostar ensures that infrastructure remains watertight, resilient, and built to last for decades.
