Pouring foundations – reliable, flexible formwork system

A secure foundation is essential for any building project. It ensures that everything stands securely and straight, and also protects against moisture and other influences from below. This applies to single-family houses as well as to garden houses or carports. Accurate formwork is crucial for success. BT innovation offers you a reliable, flexible formwork system that supports you in your construction projects.

Step by step guide

You don’t have to leave the pouring of foundations to the professionals. Especially for smaller projects such as terraces and carports, you can also simply do it yourself. Square, round, strip foundation or base plate – we explain how you can quickly and easily pour your own foundation with Syflex®. The Syflex® system consists of a recyclable, flexible formwork plank and a system eccentric for quick fastening to a support (soil nail or similar). This is how you proceed step by step:

  1. The Syflex® formwork elements can be fastened e.g. with ground nails. The spacing of the fixings depends on the nature of the subfloor and the deflection of the formwork elements. So werden in Rundungen die Erdnägel enger gesetzt, um auftretende Spannungen abzufangen.
  2. After setting the soil nails, the Syflex® formwork profile is fixed by means of the system eccentric (flip the eccentric lever).
  3. To align the formwork to the exact height, the system eccentrics are slightly loosened again and the formwork element is levelled accordingly. Now tighten the system eccentric again. Ready!

This is what you should pay attention to when pouring a foundation

If you are trying to pour a foundation yourself for the first time, here are a few more tips to help you achieve a safe, stable result in the end.

The right dimensions

Your foundation should be as big as what is to stand on it. Protrusions provide a point of attack for moisture. If the foundation is too small, it will not be possible to ensure a secure footing for your building project. Also remember to include the thickness of the formwork.

Type of concrete

There are different types of concrete, which have different compositions and therefore different properties. There are different types of concrete, which have different compositions and therefore different properties. This is mixed from sand, gravel and cement. The compressive strength class is also decisive. A concrete of class C 20/25 is usually stable enough for a floor slab. For smaller foundations, it is worth buying ready-mixed concrete. It is already mixed in the right composition and it usually says what it is suitable for.

Observe weather

It is not only when you are watering that the weather has an influence on the result of your work. The concrete must also have the opportunity to harden. This takes one to two days, depending on the concrete. During this time, it should be dry throughout and there should be no frost. So take a look at the weather forecast beforehand and also look at the next few days. It takes two to three weeks before the concrete can be fully loaded. If it is very hot during this time, you should water your new foundation every two days to avoid cracks in the concrete.
