Build Your Precast Concrete Kit
Our standard kits fit most projects. But if you need something specific — different coverage, extra reinforcement, custom quantities — build your perfect kit here.
Let's Build Your Kit
Tell us about your project and we'll calculate exactly what you need.
How big is your worktop?
Measure the total surface area in square metres — we'll show you exactly how below.
Where will this live?
Outdoor worktops need a thicker core for durability against the elements.
How do you want to build it?
A shuttered lip saves weight and materials. Full thickness is simpler to mould.
What's your thickness?
Minimum 20mm for internal, 30mm for external.
What's your core thickness?
Minimum 20mm for internal, 30mm for external.
What's your visible edge height?
This is the total height of the visible edge at the front.
What's your total edge length?
Measure all visible edges and add together in metres.
Choose your colour
All five colours available. Same formula, same strength.
How many openings do you need?
Openings for sinks, hobs, or taps. Each opening needs reinforcement bars.
Choose your sealer finish
Matt gives a natural concrete look. Satin adds subtle sheen.
Want a bit extra for safety?
We recommend 10% extra to cover spillage and mixing — most people add this.
