Floor Screeding Carmarthen Wales (SA31): If you are hoping to install underfloor heating, have a damaged or uneven floor or are restoring a property or basement in your Carmarthen home, then it is the perfect time to think about bringing in a floor screeding professional. Before it's possible to lay a final floor covering, whether it's tile, wood or carpet, the surface of the floor needs to be as flat as possible; which is why screeding a floor is essential. If you would like your floors to last a long time then a floor screed is the most important factor in any building or renovation project.
FLOOR SCREEDING COMPANIES CARMARTHEN
Whatever size or shape of room or area you are remodeling, a floor screeding company in Carmarthen will be able to supply the expertise and correct working methods to establish a perfect base for your flooring. After analyzing your project they will advise you about the perfect choice of screeding and which method of applying it is most appropriate for your situation.
Your screeding specialist will also tell you if a structural engineer is required for your project, in order to evaluate flex strength, point loadings and load bearing that your screed floor may need to conform with current British Standards and building regulations.
Bringing in a qualified and highly trained contractor will guarantee you get the appropriate form of screed for the room's intended purpose to extend the lifespan of your floor. A correct mix of screed and the techniques used for laying it are also important to guarantee the final durability of your floor surface.
There are numerous screeding specialists in the Carmarthen area so try to get multiple price quotes for your floor screeding project before picking a company and know to what standard of finish it's for. The Surface Regularity (SR) finish is the figure to look for when reviewing an estimate from your Carmarthen screeding contractor. Each of the three SR levels offer different levels of finish, with SR1 offering the best, with the lowest amount of deviation over the surface area. An SR2 or SR3 level may mean there are flat spots or ridges that could cause issues when laying your final flooring surface (wood, carpet, tile etc).
The regulations laid down in the British Standards BS8204 must be followed by any Carmarthen floor screeding company and they must also be approved by the manufacturers of any specialist screeding materials (Gypsol, Cemfloor, Flowcrete etc.) to confirm their competence and safe working practices. This accreditation program illustrates a firm's performance and training in the usage of a manufacturer's products.
Carmarthen commercial screeders might be involved in screeding floors in warehouses, factories, schools, salons, hospitals and shopping centres.
TYPES OF SCREED
Standard Screeds - This is acceptable for everyday domestic use and is a combination of sand and cement. 5 parts sand to 1 part cement is the normal mixture for standard screed. This five to one ratio standard screed will set hard at a rate of one millimetre per day after applying.
Advanced Drying and Fast Drying Screeds - If you have to use the floor at the earliest opportunity a fast drying screed can be used. They're usually a fibre reinforced type of screed that dries out at a rate of between three and seven millimetres per day and are employed in time-sensitive flooring projects.
Self-Levelling or Liquid Screeds - A latex and cement mixture which can produce the highest standard SR1 finish. Primarily used to finish off a poor substrate level or damaged floor so as to lay a brand new flooring surface, such as vinyl planks on top of it. These can be as little as 1mm thick, and due to the latex polymers, will still provide high strength.
Polymer Screeds - Provides an extremely high level of strength with a reduced thickness. Manufacturer's guidelines for setting times are different across the product ranges.
Fibre Reinforced Screed - The favoured choice by professional contractors for use with underfloor heating systems. The improved strength and flexibility provided by the special fibres within this screed mix help protect the resulting floor from thermal cracking and shrinkage. The screed will set hard at a rate of 1mm/day.
Industrial and Heavy Duty Screed - A screed that is designed for high load and heavy traffic areas where maximum strength and durability is crucial.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is crucial for a top quality screed surface that will be hard wearing and durable. It is crucial that all contaminants such as oil, debris, paint or grease is eliminated from the base before laying any screed, as these can affect the bonding capability that a quality floor screed requires.
Any cleaning products that are used in this stage shouldn't leave any residues, and the floor base must be permitted to dry by itself naturally. It is necessary to repair any crevices or cracks in the base to avoid them being mirrored and "travelling" upwards into the freshly screeded floor. During a site survey the screeding company will notice what preparations are needed before starting to work on the screeding.
To shield the flooring materials and screeding layer from dampness rising up through the ground, a DPM (damp proof membrane) must be installed. The DPM is made out of thick polythene and various layers might be used to serve as a moisture barrier for the screed.
If the area is at risk from radon gas then an additional barrier is needed to stop this harmful gas from entering via the ground. If radon gas occurs in severe doses then a complete ventilation system may be installed underneath the screed which will remove any gases that might seep in from the ground.
The final stage of surface preparation is the spraying or painting of a sealer or primer. Sealers and primers help with the bonding process and are special applications specifically designed for the kind of screed being applied. Owing to their specialist nature, only trained screeding specialists in Carmarthen should be entrusted with using them correctly, safely and through the use of equipment that's made for this task.
Under floor heating can now be laid out, installed and tested before the screed is poured. The under floor heating system will be carefully positioned and mounted firmly on insulation panels to stop potential movement during screed installation process. Under floor heating is one of the most effective ways to heat a room and a properly installed system will deliver even warmth across the floor area.
Needless to say, if you are not fitting under floor heating, you can just bypass this step and get on with applying the screed. Your use of the room will assist your screeding specialist on what type of screed is appropriate for your needs. After the application of the screed there's a minimum 24 hours (for quick drying screeds) before you are able to walk on the surface, and a 72 hours minimum drying period before the laying of any flooring materials. If you're using heavy duty or standard screeds the setting time is longer and you should observe the manufacturer's guidelines so as to get the best finish for your floor.
As soon as the screed has hardened it can be checked for quality to ascertain its SR level. The standard SR test involves the use of a 2m long straight-edge to check for any deviations in the floor surface.
- SR1 - Over the whole screed area, if there aren't any disparities of more than 3mm from the straight-edge, then you have a top quality SR1 standard surface.
- SR2 - SR2 is the classification for standard floors in commercial and industrial projects and can deviate from the straight-edge by up to 5mm.
- SR3 - SR3 is utility standard where a perfect quality finish isn't needed. This specification allows for a maximium deviation depth of 10 millimetres.
If you need load bearing checks, a qualified structural engineer is necessary to perform the tests. The testing will make sure that your newly laid screeded surface is viable for the load bearing requirements specified in the original site survey. This can include what's known as a "drop hammer test" which assesses various aspects of the flexibility and strength of the screed. Any screeding that's got point load requirements must be sanctioned by a competent structural engineer heeding the BS8204 regulations.
