To meet programme deadlines, it is useful and sometimes even necessary for contractors to maximize pour sizes. These large concrete bays must also be properly waterproofed. It is essential, in such cases, to limit the width of surface cracks. RASCOtec crack-inducing units provide an unbeatable solution wherever the bay size necessary for economical concreting exceeds the engineer's specifications.

RASCOtec crack-inducing units, installed at predefined intervals, allow concrete pours of any size without the risk of uncontrolled cracking.

Made from HDPE, RASCOtec crack-inducing units are incorporated in:

• Ground slabs
• Walls
• Suspended slabs

Special HDPE widening components can be used to adapt the 20 cm wide base profile to any element shape and thickness. As HDPE is as easy to work as wood, any necessary fitting to the element geometry may be performed directly on site.

Naturally enough, these dummy joints need to be sealed. RASCOtec crack-inducing units, like RASCOtec injection channels, are injected with RASCOR's low-viscosity RASCOflex acrylic grout. Both installation and grouting may be carried out in all weathers.

The RASCOtec crack-inducing units play a key role in ensuring the top-class performance of RASCOR's "White Tank" waterproof concrete basement system.
