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
