Introduction
For decades, constructing concrete staircases on site meant building temporary formwork, waiting for curing, striking the formwork, and then returning later to install balustrades. It is a process fraught with delays, safety risks, and hidden costs.
At Stair Formwork Ltd, we offer a better way. Our prefabricated stair formwork system is designed to replace traditional methods with a solution that is faster, safer, and more cost-effective.
The Traditional In-Situ Method
- Step 1: Build temporary formwork on site.
- Step 2: Pour concrete and wait for curing (often 7–14 days).
- Step 3: Strike the formwork and make good any defects.
- Step 4: Install temporary edge protection or temporary stairs.
- Step 5: Return later to install permanent balustrades.
- Step 6: Make good again where balustrade fixings have disturbed finishes.
The Stair Formwork Ltd Method
- Step 1: Our prefabricated stair flight arrives on site with balustrade already attached.
- Step 2: Crane into position and fix.
- Step 3: Pour concrete.
- Step 4: Move to the next floor (24hour).
The Cost and Time Comparison
Traditional methods require multiple trades, multiple visits, and multiple inspections. Our system consolidates the process into a single installation.
- Labour: Reduces on-site labour hours by eliminating temporary works and follow-on trades.
- Programme: Progressive installation means floors can be concreted as the build develops. On the Lewisham project, this saved an estimated 4 weeks over 75 levels.
- Safety: Permanent balustrades are in place from day one, reducing the risk of falls.
- Quality: Factory-controlled manufacturing eliminates “making good” and ensures consistent results.
Conclusion
If you are responsible for programme and budget, the choice is clear. Stair Formwork Ltd delivers stairs that are faster, safer, and more cost-effective—with no redesign necessary.
