Strip-line terracotta clay bricks turn a small surface profile into a facade-wide directional effect. Orientation, module, light, joints, runoff, dirt collection and cleaning must therefore be evaluated together with the exact product and complete wall construction.
Document the exact strip-line geometry
Request a current product code and drawing showing length, height, thickness, tolerances, rear profile, edge detail and unit mass. The face drawing should define groove direction, spacing, width, depth, end conditions and any permitted variation. Verify whether the archived 60 × 240 × 11 mm size remains current.
Clarify whether the product is a bonded veneer, a mechanically supported unit or another wall-tile category. The duplicated archive type is not a technical classification. Connect the current unit to an approved installation path, substrate and evidence before using it in elevations.
Inspect several full units and representative cuts. Record whether grooves continue consistently to each edge, how corners expose the body and how the surface meets the designed joint. Retain a labelled current sample so later drawings, mock-ups and deliveries reference the same geometry.
Choose orientation with the whole elevation
Horizontal lines can reinforce courses and building length; vertical lines can emphasize height; rotated or mixed fields can create a more active pattern. These are design observations, not fixed rules. Draw the intended orientation at every facade zone rather than relying on a general note.
Coordinate groove direction with the unit module, bond, joint width, openings, parapets, soffits, corners and adjacent materials. Check how unavoidable cuts terminate the lines. A small misalignment that seems minor on one tile can become obvious when repeated across many courses.
Study light, distance and shade range
Raking light
Review how low-angle sun and facade lighting reveal groove depth, surface variation and installation tolerances.
Viewing distance
Assess close approaches, oblique views and distant elevations; the same profile reads differently at each position.
Fired variation
Approve a physical colour and texture range across several current units rather than one image or sample.
Joint contrast
Test joint colour and width with the grooves because both contribute to the facade’s overall line density.
Prepare elevation studies and a full-size mock-up under representative light. Record the accepted direction, mixing method and alignment tolerance. Retain labelled control samples from the approved range so production and site decisions remain traceable.
Control runoff and dirt collection
Map water from copings, sills, roofs, ledges, joints and adjacent materials. Grooves and surface relief can influence visible wetting and deposits, but they do not replace wall drainage. Detail drips, projections, flashings, cavities and outlets through the complete wall design.
Identify sheltered zones, splash areas, concentrated discharge and air-pollution exposure. Trial construction cleaning and routine maintenance on the exact surface and joint. Check whether groove bottoms retain residue and whether tools can reach them without changing the face or joint profile.
Include typical sill runoff, coping discharge or landscape splash in the mock-up when those conditions shape the design. Observe the agreed trial rather than extrapolating from a dry sample. If visible deposits appear, adjust the water detail, maintenance access or material junction before approving broad use.
Do not promise self-cleaning or permanent freedom from streaks. Use a maintenance plan with accessible inspection points, suitable trialled methods and a way to diagnose the moisture source before treating a visible stain.
Resolve joints, corners and openings
Draw the module through window heads, jambs, sills, doors, corners, movement joints and interfaces. Decide where the line pattern continues, stops or turns. Confirm whether current corner units exist or whether returns use cut pieces, a different module or another material.
Show movement and sealant joints as technical components within the pattern. Coordinate joint depth, backing, adhesion surfaces and compatible materials with the responsible wall-system design. Avoid hiding required movement joints merely to preserve an uninterrupted line.
Verify product and wall evidence
Create a matrix for dimensions, absorption, strength, freeze–thaw, chemical exposure, reaction to fire and other project requirements where relevant. Check code, size, thickness, surface, laboratory, test method, date and scope. Archive claims such as “firebrick” or “heat insulation” do not establish whole-wall performance.
The wall team should also address support, adhesion or fixings, water management, movement, wind actions, fire interfaces and substrate compatibility. A quality-management certificate does not prove those outcomes. Begin current product review with the terracotta brick range, subject to exact-system verification.
Mock up, inspect and maintain
Build a representative wall area with typical light, joints, corners, openings, flashings and sealant interfaces. Include the proposed installation and cleaning sequence. Use the approved mock-up to set workmanship expectations for groove alignment, lippage, cuts, shade distribution and residue removal.
Hold a preinstallation review using the approved drawing, samples and mock-up. Establish setting-out controls, the sequence for mixing batches, tolerances at course starts and stops, and who can accept a visual deviation. Record changes before the reference panel is altered or dismantled.
Record delivered batches, substrate acceptance, installation areas, coverage or fixing checks, joint work, flashings and cleaning trials. Review relevant project references for visual context only. At handover, retain as-built details, batch locations, inspection access, maintenance guidance and labelled spares.
