Floor Level Tripods for Screed & Concreting

Product Information

After about 24 hours you should be able to walk on the surface and it will be a week before you can start to build non-load bearing structures like partition walls. Form work will be needed around obstacles and troublesome pipe work etc so that you can ensure that water and screed does not get to them. Anhydrites are very sensitive to drying conditions — it helps if the walls are plastered and dried out first so that room moisture levels aren’t too high. It is likely that you will need to have some expansion foam around the edges of the room, against the wall between it and the screed when it had been poured. This will allows slight movement of the screed as it warms and cools and therefore expands; the size of the room and therefore the amount of screed and the type of screed will influence what is needed. Made of the right stuff – for dealing with flowing concrete a steel dapple bar is heavier and more suited to a dense product and is generally more robust. Ideally it will be powder coated for longer life and easier cleaning.

As the screed dries a thin crust forms on the top which is called laitance. This needs to be removed by sanding before the floor is tiled, however if other floor coverings that do not need an adhesive are used you only need to brush and vacuum the residue. Different manufacturers and suppliers will have different proprietary products so there will be some variation and they will be able to provide specific details. While there is this range in practical terms you have the following choice: The preparation for the most part will not differ to traditional screed. The only one difference is that there should not be any gaps where the screed could leak from. This means that when installing the insulation, all the joints should be taped up. In addition, if there is a gap in the wall, make sure some kind of reinforcement is placed there as the pressure of the screed can result in a leakage. In essence, the aim is to make a water tight pool so that none of the flowing screed can leak or break any of the barriers if there isn’t a solid wall in place. Self-levelling concrete is typically used to create a flat, smooth surface with a compressive capability which is similar to or greater than that of traditional concrete.

What about these?

They will use a number of screed levelling tripods positioned in various points across the room. These are adjusted so that the flat plate at the centre of the tripod is at the height that the screed will be. This is done using a datum which is transferred to each tripod using a laser level. Make sure you choose the right screed to lay over your underfloor heating pipework to optimise its effectiveness. (Image credit: getty images) How Much Does Floor Screed Cost? In this case study, we look at the process of laying liquid screed in a home renovation project, and hopefully by the end you’ll have a better idea of what to expect! Under-floor heating is more effective, not only because it is not heating a larger depth/volume of screed, but because the liquid flows all around the pipes so heat transfer from the pipes on more effective We supply robust stainless-steel flow cones & flow plates for slump testing. This equipment is used by screeders to determine the flowability/slump of free-flowing, self-levelling liquid screeds such as Gyvlon, Breedonflow Screed, Isocrete, Supaflo and many more.

Tripods: Get it right, get it level – Your floor will need to be accurately levelled and for that you will need to use levelling tripods. Ideally you should look for a stainless-steel finish for long life and easy cleaning. We hope this case study has shown you what to expect when laying liquid screed in your building or renovation project, and given you a better idea of what you need to consider if you do decide to go ahead with it. If you’d like to dive into a bit more detail, we have more info on the preparation for laying liquid screed, different types of screed, screed tripods and dapple bars. Our Screed and Concrete Tool Knowledge Base is also here to help if you have any questions on the tools involved in screeding. If time is short the process can be speeded up using ‘force drying’ techniques, shrinking drying times to less than 40 days.Flowing screed is becoming a very common practice. This is largely due to it being applied in liquid form instead of being semi-dry like traditional screed is. The result is that it can be applied at a rate of 500-1000m2 and with certain products a coverage of 2000m2 can be achieved in a single day. In comparison, traditional screed is usually applied at a rate of 100-150m2 a day. As you can see, the difference in application rate is huge. Conventional sand/cement screed uses a relatively strong mix (1:3 cement to sharp sand) with a fairly dry, almost powdery consistency. The first step will typically be done by your chosen contractor: Step 1: Measuring the Amount of Screed Required

Liquid screed is the modern alternative to conventional Sand and Cement screed. It is now widely used in the construction of domestic and commercial buildings and was developed to deliver a level and smooth surface onto which the chosen floor finish can be laid – tiles, wood, laminate etc. Liquid screed lends itself especially well for use with under floor heating. As it is so critical to get the right amount of screed, the contractor you are using will probably not leave this to you but come and measure the amount of screed that is needed. Too little and you will have to try and get your supplier to deliver some more as soon as possible before your current batch goes off. This is fraught with problems as mixing batches will lead to inconsistencies, assuming that they can even get another batch to you. Pumped liquid screeds are effectivelyself-levelling and self-curing, which translates into a nice level finish. While traditional sand/cement screeds aim to achieve the standard known as ‘SR3’, which permits a 10mm difference over 2m, liquid screeds aim for perfection (SR1 standard) but guarantee SR2 with a variation of plus or minus 5mm. Quality is further assured as liquid screeds are applied by specialist approved contractors. However, that doesn’t mean your floor screed is fully dry and you can just build away on top of it – DIY Doctor estimates it can take a week before you can start to build non-load bearing structures like partition walls. With Daniel & Kay’s project, the estimated time for the screed to dry fully is between 1 month and 8 weeks.

Now that everything is sealed and watertight and you are sure that the screed will be kept in the location where it should be, then you are ready to pour the screed. It is a very good idea to fill the under-floor heating pipes, if you have them, as this will stop them floating up in the liquid screed, and stopping them being squeezed by the weight of the screed. How to Pour a Liquid Screed Traditionally a screed would have been laid by shovelling in the screed mix and then levelling it with a screeding bar and/or polyurethane float. We explain the best technique for laying screed yourself in our project here.

The terminology can be a little confusing because the terms ‘anhydrite’, ‘calcium sulphate’ and ‘gypsum’ are used interchangeably. Dries at a rate of 1mm per day up to a screed depth of 40mm and if necessary it can be force dried as early as 7 days after application. As we have discovered there are essentially three board options for your screed. We will summarise the relative pros and cones of these to help you make the right choice. Benefits of Traditional Screeds The choice that you make will be based on the different pros and cons of the various options. However for more detailed information on the different types of screed available there is a lot of information published by the Concrete Centre here. Advantages and Disadvantages of Liquid or Pumpable and Traditional Screeds It is very level – much more so than is possible with a traditional screed even with a experienced professionalA screed tripod is a simple but ingenious tool used to ensure a floor is laid exactly to the correct, desired level. The tripods are three legged devices with a central screw threaded shaft at the base of which is a circular disc. The disc can be raised or lowered to set the perfect required floor level (using a laser level) prior to the liquid screed – or the flowing concrete – being poured. This is how we would advise on how best to use liquid screed tripods. In a nutshell, traditional sand/cement screed is cheaper and you can mix and lay it yourself, but it means more hard work for you and won’t get you the same perfectly level finish as with liquid screeds (although you might prefer a flat surface which isn’t level, for example for wet rooms.)
