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 alot 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?

Self-compacting concrete (SCC) is a flowing concrete that does not require vibration and flows under its own weight.

The concrete design is made up with specialty formulated admixtures and viscosity modifiers to give the concrete a high-performance flow rate. This concrete can easily flow into and around heavily congested areas filling moulds and formwork with ease.

Our self-compacting concrete can be used for many applications and can achieve an SR2 finish with the correct workmanship. Other beneficial properties include low bleed rates, increased early age strengths and ease of application which helps with labour costs.

Using this product also speeds up lead times and reduces risks of health and safety issues regarding vibration equipment. Having no need for vibrating equipment spares workers from exposure to vibration. No vibration equipment also means quieter construction sites.

1Concrete has high flowability to undergo compaction by its own weightConcrete is compacted by external means of vibration
2High workabilityLess workable mix
3Workability gained through superplasticizers and viscosity modifying agentsWorkability gained through increased moisture content
4Addition of superplasticizer increase the bond between aggregate and cement matrixThe aggregate-cement matrix is weak
5Water Content is LowHigh Water Content
6Fines Content – Cement and Fine aggregate is highThe fines content is less compared to SCC
7Lower water content decreases the BleedingBleeding is high
8Increased fines content gives a homogeneous mix with less segregation issuesSegregation is higher
9Low Viscosity due to high fines contentHigh Viscosity
10SCC structures give good aesthetic finishAesthetic finish is not satisfactory
11Good choice for thick reinforcement worksNormal concretes are limited in thick reinforcement areas due to external compaction difficulties.

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
