Buxton’s self levelling floor screed services in Northamptonshire will cut slab thickness, and speed up your site schedule. Here’s the numbers to prove it:
We pump precision self levelling floor screed across Northamptonshire, delivering flat, SR2-compliant subfloors ready for foot traffic within 24 hours
We install self-compacting anhydrite (calcium sulphate) and cementitious compounds that eradicate insulating air pockets around underfloor heating pipes, raising thermal conductivity to 2.2 W/mK. On every Northamptonshire job – from urban extensions to rural conversions – Buxton screeders laser-level each subfloor to strict BS 8204-7 SR2 tolerances, delivering a dead-flat substrate ready for final floor finish trades.
Hire Buxton Flow Screeds on your build for:
What surface flatness standard does your liquid screed achieve for high-spec domestic flooring?
We pour to BS 8204-7 Surface Regularity 2 (SR2) as standard, which guarantees less than a 5mm gap under a 2-metre straightedge. On specification, we can achieve SR1 (less than 3mm deviation under a 2-metre straightedge), giving the dead-flat datum required for large-format porcelain tiles and seamless microcement finishes.
How do you stop shrinkage cracking across large open-plan kitchen diners?
There’s negligible drying shrinkage when you use flow screeds; pours up to 1,000m² can be carried out without crack-control joints in unheated floors (or up to 300m² over underfloor heating). We recommend 8mm–10mm polyethylene expansion foam around all walls and columns, and movement joints only across door thresholds and structural thermal breaks.
How long will it take for a 40mm screed to dry naturally in our unheated Northamptonshire extension?
Under standard drying conditions (20°C and 60% relative humidity), anhydrite screed cures naturally at 1mm per day up to 40mm. For sections over 40mm, the drying rate slows to 0.5mm per day. A standard 50mm pour takes approximately 60 days to dry naturally; this can be halved by commissioning the underfloor heating system after day 7.
Can we pump liquid screed over legacy - uneven - timber floorboards in a Northampton terrace?
Not directly, no. Liquid screed is heavy (approx. 2000kg/m³) and wet. The floorboards must be sheeted with structural plywood, lined with an unbonded membrane, and you should use a fibre-reinforced thin-section screed at a 25mm–30mm thickness.
Can liquid screed be used in wet rooms and ground-floor bathrooms?
Yes, but material selection matters. Anhydrite (calcium sulphate) screeds lose strength if exposed to standing water. Instead, we pump cementitious liquid screed (such as Cemfloor), which is unaffected by residual damp and accepts standard waterproofing tanking membranes directly.
• Single-Point Technical Management – Speak directly with trade specialists who review site plans, calculate precise floor volume requirements, and coordinate pump truck logistics.
• Specialist Screeders – We install self-levelling liquid screed to laser-flat tolerances, pumping up to 1,500m² daily across Northamptonshire sites.
