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.
Self-levelling concrete has to be pumped, due to it being a “flowing product”.
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.
No. | Self-Compacting / Levelling Concrete | Normal Cement Concrete |
---|---|---|
1 | Concrete has high flowability to undergo compaction by its own weight | Concrete is compacted by external means of vibration |
2 | High workability | Less workable mix |
3 | Workability gained through superplasticizers and viscosity modifying agents | Workability gained through increased moisture content |
4 | Addition of superplasticizer increase the bond between aggregate and cement matrix | The aggregate-cement matrix is weak |
5 | Water Content is Low | High Water Content |
6 | Fines Content – Cement and Fine aggregate is high | The fines content is less compared to SCC |
No. | Self-Compacting / Levelling Concrete | Normal Cement Concrete |
---|---|---|
7 | Lower water content decreases the Bleeding | Bleeding is high |
8 | Increased fines content gives a homogeneous mix with less segregation issues | Segregation is higher |
9 | Low Viscosity due to high fines content | High Viscosity |
10 | SCC structures give good aesthetic finish | Aesthetic finish is not satisfactory |
11 | Good choice for thick reinforcement works | Normal 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
Self levelling concrete recommended!

“We have worked with Mixamate for the best part of 10 years now from our early days to where we are today as a medium sized construction company. As a business we often find ourselves working for clients where access is restricted so Mixamate is the ideal solution to our concrete and screed requirements.”
“On sites with limited space and many restrictions, there isn’t a better option than Mixamate. The drivers always do their best to make it easy for you without any complaints. I would highly recommend them for anyone looking for screed or concrete pumping.”
“We have always found Mixamate to be prompt in their service delivery with good communication throughout. I have no trouble at all recommending them to any potential client and wish them all the best for the future.”
“Excellent company. Easy and pleasant to deal with.”
“Belowground Ltd undertake many domestic foundations every year around the South East and find Mixamate the perfect solution for us as they have a large fleet so can deal with short lead in times and the pump trucks are great as saves having 2 large vehicles on site.”
