Spray concrete

In shotcrete (also known as sprayed concrete), concrete mortar is sprayed under pressure onto a supporting surface, where it hardens into a very strong whole. At SealteQ, we often apply this technique in hard-to-reach places or complex surfaces, where traditional concrete pouring does not achieve the desired result.

Solution for Concrete Renovation and Repair

At SealteQ, we effectively use shotcrete for large concrete repairs with significant damage, where greater coverage on the reinforcement is required and for creating concrete structures in unusual shapes. To achieve a sustainable and optimal result, we apply the following techniques.

The application of shotcrete offers various advantages when it comes to concrete renovations and strengthening concrete structures. At SealteQ, we apply this technique for the following reasons:

• Due to the high speed at which shotcrete can be applied, this method is very attractive, especially for large repair works or constructions.
• The shotcrete is well compacted due to the high pressure. There is a high densification of the concrete, meaning air bubbles are immediately removed from the fresh concrete. The concrete structure becomes significantly more durable and stronger.
• When repairing, for example, ceilings or tunnels, support through a two-sided formwork is often lacking. This support is virtually impossible in such situations. With the application of shotcrete, support is not necessary, making it a very suitable technique.
• Shotcrete can be applied in all sorts of shapes. The thickness of the shotcrete can also be determined as desired. This provides a lot of freedom in design and the ability to make adjustments.
• When strengthening a structure using shotcrete, concrete reinforcement is required. For thicker layers of concrete (more than 30 mm), a shrinkage mesh is needed to prevent cracking during drying. In these cases, shotcrete is the best and sometimes even the only solution.
