FLOW SCREED SERVICES
Traditional screed: Sand & Cement Screed
A sand and cement mix is the traditional way to screed floors, and can be reinforced with Polypropylene Fibres (PPF).Unlike liquid screeds, sand and cement screed drying times vary according to weather conditions, screed depth and the mix used.
- Can be supplied in a ready-mix form or site mixed using a forced action mixer
- Just like liquid screeds, sand or cement screed can be pumped into areas that are difficult to access or upper floors of buildings
- If thermal or acoustic properties are required, suitably reinforced sand and cement screeds can be laid over most types of rigid insulation or thin sound deadening quilts
Liquid screed(gyvlon): Self Levelling Liquid Screed
Self-levelling screeds are applied in a liquid form. These rapid-laying screeds are less Labour intensive and offer faster drying times than alternative materials, which helps developers speed up the construction timetable. These are generally ready for light foot traffic within 24-48 hours
These protein-free formulations can be laid at reduced thicknesses compared to semi-dry screeds, which delivers reduced shrinkage, superior compressive strengths and impressive thermal conductivity in conjunction with underfloor heating.
Unbonded installatioins start from 35mm depth
We can offer fully bonded screeds at a depth as low as 15mm!
Not only do they meet the BS 8204-7 standard for screeds, but the fact that they are also free from Ordinary Portland Cement (OPC) helps to significantly reduce the carbon emissions generated by large-scale flooring projects.
Liquid screed longfloor:
A pump applied, free flowing cement based screed that can be laid quickly, trafficked after just 24-48 hours and dries within 14-21 days.
The Fast Drying Cement based Screed is a solution that provides you flexibility in installation and your overall build programme.
The benefits of using Fast Drying Cement based Screeds include:
- Hugely reduced drying times
- Fast and easy installation
- High strength and lower depths
- Low shrinkage and quality
The Fast Drying Cement based Screeds provides a smooth level surface in both domestic and commercial buildings prior to the application of floor finishes.
Longfloor’s IntegraCure completely removes this process from the installation of the screed. Basically, Longfloor IntegraCure is a fast track cementitious screed with no laitance and no need for curing agent.
Laitance removal
Occasionally after liquid screed has been laid a thin layer of laitance is left on the surface, this means that the floor will need to be sanded. Floor sanding should be done approximately 7-10 days after application. This will not only help the drying out process but will also provide a durable & stable surface on which to add further flooring. The process of sanding is performed using specialised machines and is best completed by professional service providers.
Underfloor heating
AT APR we provide the complete package of underfloor heating from start to finish including design and specification, to testing and commisionning & final handover.
