Blockwork, levelled and gauged.

Inner skin on cavity builds, foundation blocks, dense or thermal block. Cavity insulation set as we go. Levelled, gauged, ready for plaster or face. From foundation up to wall plate, we keep the courses dead level so the carpenter is not chasing every joist.

What's Covered

Every blockwork job,
four basics covered.

Scope scales with the job. These four are the spine of every blockwork engagement.

01

Foundation Blockwork

Heavy concrete block from the bottom of the trench up to DPC level. Sat on the strip foundation, cores filled where needed for stud anchor or starter bars.

02

Inner Cavity Skin

Dense or thermal block inner skin on cavity walls, with full-fill or partial-fill insulation, wall ties set to the right pattern and spacing for the cavity width.

03

Thermal & Dense Block

Aircrete, dense and thermal block to spec. Joints buttered, courses gauged off a profile, openings formed for door and window cills.

04

Levels & Plate Heights

Ground floor, first floor and wall plate heights all set off the same datum. No surprises when the carpenter or steel arrives.

Frequently Asked

Common questions,
plainly answered.

Why use thermal block instead of dense?

Thermal block (aircrete) gives a better U-value across the inner skin and helps a smaller wall hit Building Regs without needing more insulation in the cavity. Dense block is used where the wall is structural for steel bearings, party walls and similar.

Do you build party walls?

Yes. Twin-leaf party walls in dense block with insulation between, built to Building Regs and Approved Document E for sound. Common on terraced new builds and on cross-wall extensions.

How quickly does blockwork go up?

Most domestic extensions: foundation block done in 2 to 3 days, then inner skin in pace with the outer brick. Full new-build inner skin to wall plate height: usually 2 weeks per house.

Do you set the wall ties?

Yes. Stainless wall ties to the right pattern: 450 mm vertical, 900 mm horizontal as standard, closer around openings and at the corners.
