Who Benefits from New-Build Precast?
Builders
gain consistency and speed. Accurate sills, lintels, and thresholds allow walls to rise as designed, keep openings square, and reduce the stop-start nature of adjustments during installation. Units are cast for easy handling, reducing strain and helping teams place elements correctly the first time.
Engineers
benefit from reliable dimensions, reinforcement accuracy, and predictable bearing surfaces. What is detailed on the drawings arrives ready to install, reducing the need for improvisation and supporting dependable structural performance.
Project managers
see the operational impact. Accurate components help maintain sequencing, reduce delays between trades, and simplify coordination across all phases of the build.
Our range gives builders the flexibility to match the right profile to each wall type
Sills Shaped for Modern Blockwork and Timber Frame Builds
Single Course Sills (4”)
A practical choice for standard block construction, these sills create a stable seating point with a clean edge, reducing trimming and helping walls stay uniform from the ground up. • Face: 55mm • Back: 100mm • Width: 260mm • Lengths: 400mm up to 2600mm in 50mm increments
Double Course Sills (6”)
Designed for deeper walls, these units provide increased bearing and help maintain alignment where greater framework strength is required. • Face: 100mm • Back: 140mm • Width: 260mm • Lengths: 400–3600mm (50mm increments)
Double Course Timber Frame Sills (6”)
Sized specifically for timber frame builds, these sills fit neatly beneath the frame while offering strong, dependable support for secure installation. • Face: 100mm • Back: 140mm • Width: 240mm • Lengths: 400–3000mm
Double Course Stone Sills (6”)
A wider base makes these sills ideal for stone cladding or deep façade systems, giving masons the stability needed for heavier materials. • Face: 100mm • Back: 140mm • Width: 350–400mm • Lengths: 400–3000mm
Corner Sills (Single and Double Course)
Used to maintain clean lines at corners and directional changes, these units help create a consistent profile around the building envelope. • Face profiles: 55mm or 100mm • Back profiles: 100mm or 140mm • Width: 260mm • Dimensions: 750mm x 750mm
Our lintel range supports everything from small internal spans to wide external apertures
Lintels and Pre-Stressed Lintels for Structural Support
Standard Lintels (6×4”)
Compact and versatile, these lintels suit smaller spans with ease, providing reliable support for everyday internal openings. Height: 150mm Width: 100mm Lengths: 600–2700mm (150mm increments)
Standard Lintels (9×4”)
With increased height for greater load-carrying ability, these units offer stability for longer spans while remaining easy to handle during installation. • Height: 225mm • Width: 100mm • Lengths: 600–3600mm
Pre-Stressed Lintels (6×4”)
Ideal for larger spans, these prestressed units minimise deflection and distribute load evenly, making them suited to external walls and heavier load-handling demands. • Height: 150mm • Width: 100mm • Lengths: 1200–2800mm (200mm increments)
Pre-Stressed Lintels (9×4”)
These taller sections increase strength across wide openings, turning engineered calculations into proven structural integrity. • Height: 225mm • Width: 100mm • Lengths: 1200–4200mm
Pre-Stressed Lintels (9×6”)
Designed for significantly larger openings, this wider profile provides additional bearing and superior load distribution where structural requirements are more demanding. • Height: 225mm • Width: 150mm • Lengths: 1200–4200mm
Even minor components can have a major impact on how a project comes together. Used daily on site, they support accurate placement, durability, and a high-quality finish.
Supporting Components: Door Thresholds, Cavity Closers, and Padstones
Door Thresholds
Providing a strong and level base for door frames, these thresholds ensure openings stay square and secure, reducing movement over time. • Lengths: 2100mm, 2400mm
Cavity Closer
These units help maintain cavity width, support insulation continuity, and make the installation of windows and doors more straightforward. • Height: 100mm • Width: 75mm • Lengths: up to 2700mm (150mm increments)
Padstones
Engineered to spread the load from beams and lintels into supporting blockwork, padstones prevent crushing and contribute to long-term structural stability. • Heights: 140mm or 215mm • Width: 100mm • Length: 450mm
Even minor components can have a major impact on how a project comes together
Coping, Pier Caps, and Chimney Components for Finishing Work
Saddle Back Wall Coping and End Coping
A traditional profile that directs water away from the wall while providing a sharp, uniform finish along boundary and garden walls. • Widths: 225mm and 330mm • Depth: 75mm • Length: 900mm
Radius Edge Wall Coping and End Coping
A softer edge profile with controlled water runoff, suitable for projects where a rounded aesthetic is preferred. • Widths: 225mm and 330mm • Depth: 70mm • Length: 900mm
Single Slope Coping
Designed for walls requiring directional drainage, this coping offers efficient runoff and a clean visual line. • Width: 330mm • Depth: 75mm • Length: 900mm
Pier Caps
These units protect piers from weather while delivering a neat, finished appearance. Available in multiple sizes with either saddleback or radius edge profiles. Available in several square formats: • 550 x 550mm • 675 x 675mm • 800 x 800mm Saddleback and radius edge options available.
Chimney Copings
Cast to match common block dimensions, these copings protect chimney stacks and give a tidy, precise finish. • 450 x 450mm • 450 x 900mm • 550 x 550mm • 550 x 900mm
