TYPES OF SCREED
Standard Screeds - This is ideal for standard residential usage and comprises a combination of sand and cement. Five parts sand to one part cement is the usual mixture for standard flooring screeds. Once its been laid this 5:1 ratio dries at a rate of one millimetre per day.
Fast Drying and Advanced Drying Screeds - As the name suggest, these screeds dry at a quicker rate and allow you to use the screeded area much faster. Drying at a rate of 3-7mm/day, subject to the mixture, they are normally a fibre reinforced type of screed and are great for projects that have tight schedules.
Fibre Reinforced Screed - The favoured option where under floor heating is being installed in residential homes in Harpenden. The special fibres in this screed mix enhance overall durability and strength while also safeguarding against thermal shrinkage and cracking. It's got a drying rate of one millimetre per day.
Liquid or Self-Levelling Screeds - A cement and latex material which can achieve the highest standard SR1 finish. The self-levelling compound provides a smooth and clean surface over a damaged floor or rough substrate to enable all flooring materials to be laid. Even with a depth of 1mm, the latex polymers within the mixture provide a high strength surface for a wide variety of uses.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is required, heavy duty screeds deliver maximum strength and durability.
Polymer Screeds - An extremely high strength flooring solution where a reduced thickness is needed. Owing to their different chemical compositions, these have varying setting times which can be verified by viewing manufacturer's guidelines.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a top quality screed surface that will be hard wearing and durable. It is vital that all contaminants such as oil, paint, loose debris or grease is eliminated from the base before laying any screed, since these can affect the adhesion capability that a quality floor screed requires.
Any cleansing products used in this stage should leave no residues, and the floor base must be permitted to dry out naturally. At this stage cracks need to be repaired because these can easily travel up through a laid screed and be visible in the finished floor surface. A reputable Harpenden screeding specialist will take note of these problems during the site survey and ensure that all preparations are complete before applying the next stages of the screeding process.
To shield the flooring materials and screed layer from dampness rising up through the ground, a damp proof membrane (DPM) will have to be installed. There could be 2 or 3 layers of different thicknesses of polythene to act as barriers between the screed and the insulation layer.
If the area is at risk from radon gas then a further barrier is needed to stop the gas from entering via the ground. An airtight membrane might be sufficient in locations with relatively low radon measurements, but in more serious situations there may have to be a more sophisticated extraction and ventilation system to remove any ground penetrating radon.
The final phase of surface preparation is the painting or spraying of a primer or sealant. A primer helps with the screed to successfully bond to the base and membranes and different types exist based upon which screed type is being used. These materials require qualified contractors to apply them in the right proportions by using tailor-made equipment, such as airless sprays.
If required, this is the time that under floor heating can be laid out in the correct manner and installed. Insulation panels will be arranged and the heating pipes and wires will be firmly fastened to prevent any movement while the screed is being poured. When properly installed an under floor heating system is an effective way to warm up a room and decent quality screed will retain its heat, producing an even level of warmth across the floor.
The screeding can now be prepared in situ and applied to the floor base. Your intended use of the room will assist the screeding specialist on what type of screed is ideal for your requirements. After the pouring of the screed there's a minimum twenty four hours (for quick drying and advanced screeds) before you're able to walk on the surface, and a 72 hrs minimum curing period for the laying of any flooring materials. Manufacturer's drying guidelines for standard and heavy duty screeds should be observed in order to achieve a quality finish and provide an even and stable floor surface.
As soon as the screeding has set it can be quality checked to ascertain its SR standard. The test involves using a 2 metre straight edge laid down upon the surface and any deviations from true are measured.
- SR1 - Deviations of three millimetres or less being measured across the whole area shows your screed floor to be of the finest quality and classified as SR1.
- SR2 - SR2 is for standard commercial and industrial floors and can deviate from the straight-edge by as much as 5 millimetres.
- SR3 - For utility floors where the finish is fairly unimportant SR3 is the standard and should have a deviation measurement of 10mm or less.
If you need load bearing checks, a structural engineer is necessary to carry out the tests. Using specialist equipment the structural engineer will assess the screed surface strength and viability of use in a load bearing setting. The screed should be subjected to what's known as a "drop hammer test" to assess flexibility and strength at distinct points. The specialist testing and measurement tools involved mean that this can only be performed by a certified structural engineer applying the British Standards BS8204 guidelines.

Damp Proof Membranes
A DPM (damp proof membrane) is a material used in construction to guard against moisture infiltration into walls, foundations, and floors. It's usually made from plastic or polythene and acts as a barrier to stop rising damp, which can damage buildings over the years. Installing a damp proof membrane is crucial for safeguarding a property against moisture-related problems such as mould, structural weakening, and decay.

Damp proof membranes are typically utilised in new constructions, but they can also be fitted during renovation work. To prevent moisture from penetrating, they are typically installed beneath concrete floors or inside walls. This keeps a building's interior dry and helps avoid issues like warped wooden floors, damp patches, and peeling paint.
A range of damp proof membranes exists, each suited to the specific demands of a property. Some damp proof membranes are self-adhesive, whereas others require a bonding agent for installation. The suitable membrane will be influenced by factors such as the location of the building, the type of construction, and the level of moisture risk.
Overall, an effective and easy solution to moisture problems is provided by a damp proof membrane. It forms a durable and long-lasting barrier that safeguards homes and buildings in Harpenden from the detrimental effects of damp. To ensure the structure remains dry and protected, installing a damp proof membrane is an important step, whether you're constructing a new home in Harpenden or renovating an existing one.

Latex Floor Screed Harpenden
When the make-up of your floor's surface means that a certain amount of flexibility is needed, it will be advantageous to apply a latex screed, rather than one with a more rigid finish. Latex screeds typically comprise two parts - a cementitious powder and a latex liquid mixture. The water that is normally used in a screed mix is replaced by the liquid latex, which makes it more flexible than other types of screed, and quicker drying.
Prior to the laying of your chosen decorative surface, this latex product is used for levelling subfloors. This is suitable for sub-floors made from wood, sand/cement, asphalt, quarry tiles or concrete, is perfect for the application of flooring adhesives and gives a durable, smooth surface. If there's any movement in the subfloor this type of screeding will provide a crack-free, flexible finish on which you can lay your chosen floor coverings.
Latex floor screeds aren't a suitable choice where a "floating" screed is required, for instance when a screed is being laid on the top of a layer of either thermal or acoustic insulation, such as might be the case when you're screeding over underfloor heating, and screed depths of 50-65mm may be required.
Screed Reinforcement
Screed reinforcement is employed to bolster the durability and strength of concrete screeds. Screeds are thin, flat layers of concrete that are applied to a base layer to create a level surface. Flooring is a common use for them in building projects, but they can also be used as a finishing layer for walls and ceilings.

The addition of reinforcement materials such as polypropylene fibres, wire or steel mesh into the screed mixture during installation improves strength and prevents cracking. The reinforcement helps the surface to evenly distribute weight and load, as well as improve its ability to resist thermal changes, abrasion and impact.
With the use of screed reinforcement, building professionals can make certain that their projects are built to withstand the test of time and provide a high-quality and functional surface for years to come.
What Does Screeding Do?
Screeding serves several important purposes in construction projects:
- Surface Protection.
- Underfloor Heating System Support.
- Corrections to Subfloors.
- Compatibility with Floor Finishes.
- Stability and Structural Integrity.
- Smoothing and Levelling.
- Improving Thermal and Sound Insulation.
- Load Distribution.
In a nutshell, creating a stable, durable and level floor surface is a vital role played by screeding. By providing a solid foundation, it ensures that the floor finish maintains its quality and aesthetics, and withstands the demands of day-to-day use over an extended period.
Concrete Floor Moisture Testing
Concrete floor moisture testing is one of those jobs that often gets pushed aside, although it can save a lot of hassle later on once the screeding or flooring goes down. Fresh or existing concrete can hold onto moisture longer than you might expect, and if that isn't picked up early, it can lead to problems like poor screed bonding, lifting, or damp patches showing through finished floors. The process usually involves checking moisture levels with specialist tools, whether that is a surface meter or a more in-depth test to see what is going on below. It isn't just about ticking a box, it helps to decide whether the floor is ready, or if it needs more time to dry out. Skipping this step can cause delays further down the track, therefore getting a clear moisture reading upfront will make the whole screeding job run a lot smoother.
