Dramix® READY, reinforcement for foundation slabs The safe and smart way Dramix® steel fibre concrete reinforcement is an excellent alternative for traditional mesh reinforcement and is capable of supporting the construction loads and bending moments. For family houses, small apartment blocks, residential and utility buildings, Dramix® steel fibres offer an easy and cost-effective way to reduce crack formation.

Still quoting for mesh? Think again! -

Keep it simple: make use of our professionally designed reinforcement solution for specific project requirements.

Save money:

-

eliminate mesh and reduce your construction time. by designing in the most economical way with the best in class fibres, we save on your budget.

Reinforce homogeneously:

glueing fibres into bundles guarantees quick and easy mixing with a uniform

distribution. -

Avoid risk:

replace steel with steel. With 40 years of experience, Dramix® is the proven solution.

Yes! It is ✔ ✔ ✔ ✔ ✔ ✔

a designed solution. as good as mesh to reduce crack formation. the economical solution supported by CE product certification. an easy to dose and mix fibre dosage. easy to pump, simple to pour and easy to finish. an environmentally friendly solution: less energy consumption per square metre compared to mesh.

Design notes: ✔ ✔ ✔ ✔

!

Bekaert warrants the validity of its software and the resulting design note as a methodology. Bekaert is nevertheless unable to have an insight in (and a control over) the correctness of the data (such as but not limited to correct geometry, materials and design conditions). The choice between different foundation techniques is to be made by the building engineer. No allowance has been made for settlements and deformations of the subground or foundation.

Practical recommendations: ✔ This system is only suitable for foundations with elastic subbase and without significant water pressure. (The occasional use of thermic insulation as subbase requires a minimum compression modulus of 120 kPa - 10 % compression)

✔ Thickness of raft should be between 200 and 400 mm. Maximum slab dimensions without dilatation joints: 25 m x 15 m. ✔ The solution must be checked and approved by the statical engineer responsible for the project. ✔ Keep the auxiliary reinforcement to cover peak moments (i.e. point loads, heavy line loads, corners, …).


A recipe for quality, cost-efficiency and the environment. It’s all in the Dramix® package. 1. Approved and controlled fibres 1 A reinforcement in line with regulations and local standards CE approved fibres: solutions with

optimal fibre dosage and CE certificates. Request your CE certificate. A solution offering a minimum of 4400 metre wire reinforcement in each cubic metre

This multidimensional steel web ensures an efficient redistribution of tensions, which are required for optimum crack control.

2. Quality controlled reinforced concrete At your concrete plant, Dramix® is mixed industrially into a first-rate, homogeneous all-in-one reinforcement solution. This quality controlled building material – in line with your design – is then delivered to you as an end product.
