About passiveslab

Focused on You, From the Ground Up

At Passive Slab, our work is centred around one thing: providing the support, products, and reliability you need.

We design and supply insulated foundation systems for low-energy and Passive House homes — but we see our role as much more than just providing materials. We’re here to simplify the process, solve problems before they appear and make sure you have exactly what you need at every stage of your project.

Whether you’re a first-time self-builder, an architect working to key energy performance targets, or a contractor delivering multiple units on a deadline, we adapt our service to suit the way you work.

How We Work

No two builds are the same — and neither are our clients. That’s why we offer a flexible, responsive service built around your priorities.

  • Need materials delivered quickly and efficiently? We’ll supply everything, clearly labelled and ready to go.
  • Want someone to guide your team through key stages? We’ll provide clear, practical support on-site or remotely.
  • Prefer the whole system handled for you? Our in-house team can handle everything from engineering design through to placing the reinforced concrete slab along with everything in between.
 

However you choose to work with us, we’ll make sure the foundation performs — in thermal efficiency, structural integrity and ease of installation.

A Service-First Approach

We understand the pressures of modern construction. Delays, confusion, and uncertainty are often common — but they shouldn’t be.

Our job is to make your life easier by being clear, consistent, and helpful from first contact to final pour.

Here’s what you can expect:

  • Fast, honest communication
  • Detailed technical knowledge
  • Transparent pricing and timelines
  • A team that values quality and reliability
 

We don’t make assumptions. We listen, ask questions and help you make informed choices — so your foundations do what they’re supposed to.

Who We Work With

  • Self-builders and homeowners
  • Architects and design teams
  • Contractors and developers
  • Timber frame, SIPS and ICF specialists
  • Low-energy extensions and retrofits
 

Whether it’s a one-off home or part of a larger development, we’ll help you get the fundamentals right — so the rest of your project can run smoothly.

Built for Performance, Backed by People

Meeting today’s energy targets takes more than good intentions — it takes reliable systems that are proven to perform. The insulated foundation slabs from Passive Slab are designed to meet those standards — delivering excellent performance, no thermal bridging and lasting structural integrity.
