ACTFLEX POLYCRETE: When a Mini Sledgehammer Isn’t Enough

We like to say ACTFLEX POLYCRETE is built different. But sometimes words aren’t enough—so we put it to the test.

The Test:

A screed sample, ranging from just 3mm to 40mm, was bonded directly over a polyurethane waterproofing membrane. After curing for just over 1 days (24 hours), we hit it with a mini sledgehammer. 

The Result: 

  • No cracking 
  • No lifting 
  • No damage 
  • Fully bonded and solid 

This test proves what we already knew:

ACTFLEX POLYCRETE is one of the toughest, most reliable bonded screed solutions on the market. 

Key Benefits: 

  • Works from 1mm to 80mm thickness 

  • Adheres directly to waterproofing 

  • 40-minute working time 

  • 45 MPa tensile strength 

  • Trafficable in 4–6 hours 

  • Waterproofing-ready in 24 hours 

  • Shrinkage-free, high flex performance 

Where to Use It: 

  • Over membranes 

  • Patching thin and thick areas 

  • Ramps and sloped builds 

  • Pre-tile screeds 

  • Bonded under-tile areas
