Business overview

BESPOKE FLOORING AND UNDERFLOOR HEATING Southern Liquid Screed is a flooring company that designs bespoke flooring solutions, underfloor heating, resin, polished concrete & screed


Southern Liquid Screed based in Portsmouth is a flooring company that installs environmentally friendly, quick drying and economical liquid screed. We deliver polished concrete flooring solutions throughout the UK. We also offer a bespoke underfloor heating design and installation service. With a reputation second to none, our teams are very experienced, hard working and will go the extra mile to ensure complete customer satisfaction.


Our core products are Gypsol’s anhydrite binder which is manufactured to CE certified standards by Francis Flower – the only wholly UK-based independent manufacturer of anhydrite floor screed binders.

Gypsol is used as the primary ingredient in pumpable self- levelling screeds. Whether you are an architect, designer, main contractor, self-builder or a flooring contractor, Southern Liquid Screed will ensure you get the most out of Gypsol’s screed in your project.

GYPSOL’s flowing floor screeds offer a cost-effective and environmentally friendly alternative to sand and cement. Implementing GYPSOL’s screed will help ensure that your clients enjoy an underfloor heating system that delivers exceptional results and lower running costs.


Before you decide on your flooring solution, call SLS for a friendly discussion about your project. Our team has a wealth of experience with regards to the construction of floors and underfloor heating systems. You can quiz our technical teams, who will give you qualified advice about the best way forward.

Our experienced team will help you decide what type of floor covering you require; they will survey your site, help you prepare the site, pour and level the screed and provide professional aftercare.

SLS will coordinate with your site / project manager and sub contractors to ensure that our service integrates with your project timeline.

Excellent service & quality from SLS

This is the second time that we have used SLS for liquid screed and again fantastic service, on-site staff could not have been more helpful or attentive providing a excellent job all delivered on time (2 days before Christmas) and fitting in within our schedule. The site was left clear and clean, with any debris swept up and removed. Communication from Zac and Peter was always very good, we would highly recommend SLS for liquid screed floors. Cheers Guys.
