What is self-levelling concrete?
Self-Levelling Concrete is a polymer modified cement that has high flow characteristics and gains strength just like normal concrete does. Now you would have thought wow this must need allot of water to get a flow like this!!! No this is not the case; the concrete is designed using a WRA admixture (Water Reducing Agent) that allows the concrete to flow but without the risks of strength loss. The concrete is carefully tested by our on-site technical team using a flow board and measuring tools, and to get that smooth finish all that’s needed is a dappling bar.
Why use Self-levelling concrete?
- Ease of Application
- Less Labour Required (Cost Reducing)
- Levelled and smooth surface is obtained with ease
- Water resistant surface
- Easily pumped
- Best option where formwork is arranged in unusual geometry
- Compressive strength higher than traditional concrete is obtained
- Self-Levelling is cohesive and resits bleeding and segregation issues
Application of self-levelling concrete
- Formwork in place with membrane ground sheet applied
- Concrete pour area clean from debris and dirt (Must be clean to avoid voids being formed)
- Wait for one of our friendly drivers to arrive who will work out pipes required for placement
- Pour concrete to desired level
- Dapple concrete surface using an up and down motion to create small wave ripples on the surface
- You should now see the concrete becoming smooth with few air bubbles
- After concrete pour is complete, we recommend a curing agent to be applied to the surface of the concrete, this will reduce the risk of shrinkage cracks
- Wait for the concrete to harden usually walkable within 24 hours depending on weather conditions
