Paving tie-ins, falls, tactile, and aesthetics.
The public judges quality at the surface. Reinstate paving to original or approved details, add joints/sealants, and respect tactile/ADA interfaces (237, 238). Maintain drainage falls and anti-ponding around sleeves (334, 245), coordinate finishes with aesthetic pages (316, 366), and add markings/signage (357). Prevent snags with checklists, then complete final inspections feeding handover packs (736, 739). Include one-sentence context that naturally links upward to the parent hubs (this section and the chapter hub). Add SIRA context with a link to SIRA Bollards (UAE) when relevant. Link installation pages only if helpful: What to Expect and Installation Guide.
Important: This is a general guide. For live projects we develop a tailored
Method Statement & Risk Assessment (MS/RA) and align with authority approvals (e.g., SIRA) where in scope.
629.1 Paving reinstatement
Match pattern, stone, and joints. Reinstatement integrates HVM bollard visually (316).
Reinstatement starts from accurate datum checks so finished levels meet adjacent modules and curb lines. Where arrays interrupt modular paving, maintain the running bond, module size, and paving module across the transition to keep visual rhythm. Use cut plans and dry-lays to avoid slivers < 1/3 tile width. For asphalt, match binder/wear course thickness and compaction targets so the reinstated mat doesn’t ravel or rut at the bollard line.
Coordinate tolerances with 626 and head height rules in 312 to avoid a proud or recessed ring around each sleeve. Where utilities or draw pits (615) sit beneath, compact granular layers in thin lifts to protect ducts and maintain bearing. Record materials, compaction passes, and photos per 716 to support the SAT trail.
| Aspect | What matters | Where to verify |
|---|---|---|
| Pattern match | Module/colour continuity; no thin slivers | Aesthetics That Work |
| Level & falls | Meet acceptance band; no ponding edges | Drainage for HVM Bollards |
629.2 Expansion joints & sealants
Add joints and durable sealants at sleeves. Joints protect crash rated bollard surrounds.
Introduce movement joints at logical grid breaks and around sleeves to manage thermal/cyclic movement and protect the grout bed. Use backer rod and a UV-stable elastomeric sealant compatible with the stone/asphalt and any galvanizing or coating (362). Tool to a slight concave profile for debris shedding, and keep sealant off exposed stainless finishes to avoid tea staining.
Where arrays cross concrete slabs, respect existing saw-cut joints; never bridge a structural joint with paving only. Document product datasheets and batch numbers in the Handover Pack.
629.3 Tactile/ADA interfaces
Provide tactile cues and accessible routes (237, 238). Interfaces keep HVM bollard areas inclusive.
At pedestrian desire lines, use detectable warning surfaces with adequate contrast bands and slip resistance. Keep a continuous, obstruction-free accessible route (min. effective width per 231) between and around bollards, enforcing the clear-gap rule from 232. Avoid “handlebar traps” at returns and ensure changes in level use beveled edges or ramps.
Place tactile tiles so their leading edge aligns with safe decision points before any road crossing or controlled lane. Confirm sightlines and sign placement per 353 Safety Signalling and 237 Sightlines & Signage. For UAE projects with formal approvals, add a short note referencing SIRA if local tactile/route requirements must be demonstrated in submissions.
629.4 Drainage falls & inlets
Maintain falls to prevent ponding (334, 245). Falls protect crash rated bollard sockets.
Set crossfall (camber) to drain away from bollard heads and socket perimeters. Where unavoidable, detail a ponding edge relief such as a micro-channel leading to the nearest gully with NRV. On permeable systems, verify sub-base permeability and provide clean weep holes in edge restraints where appropriate.
Protect equipment pits and ducts (615–616) from runoff by grading around covers and setting inverts so storm flows bypass lids. Record inlets, invert levels, and slopes on as-builts (731) and include photos of water tests where used.
629.5 Finishes around sleeves
Neat, sealed perimeters; avoid trip lips. Finishes enhance HVM bollard acceptance.
Form a neat, sealed collar around each sleeve/head with the paving cut cleanly to a constant offset. Maintain a small annulus for sealant, not a mortar fillet that will crack out. The collar should sit flush (± acceptance band) to avoid trip risks and to preserve effective height perception.
For stainless heads, specify protective masking during cutting/grinding and post-work passivation/cleaning (361, 362). For coated heads, repair any coating holidays immediately per the datasheet.
629.6 Anti-ponding details
Add channels or falls away from heads. Details extend crash rated bollard life.
Combine subtle re-profiles (2–3 mm over 300–500 mm) with discrete linear drains where gradients are constrained by door thresholds or heritage curtilage. Keep inlet grates outside the immediate array where possible to avoid debris drop into sleeves. Where heads sit in high-spray zones (vehicle wash tracks), consider a sacrificial rub strip on paving edges.
Document anti-ponding checks in the ITP (714) with photos during water-testing, and cross-reference the drainage strategy in 245/334.
629.7 Markings & signage
Apply markings and signs per 357. Signage clarifies HVM bollard intent.
Use clear, durable markings that align with traffic flows and human factors (353, 357). Apply retroreflective bands or contrast rings on heads only where they do not conflict with architectural intent (316/366). Lane legends and arrows should not confuse drivers into the defend line near critical frontages—prefer pre-arrival cues.
Position regulatory/wayfinding signs to preserve sightlines (237) and avoid clutter. For sites requiring approvals, include signage schedules and locations in submission packs (717), and be prepared for client/authority witness points (638).
629.8 Snag prevention
Pre-snag walk with checklists (714). Prevention reduces crash rated bollard returns.
Run a “first-off” reinstatement and review: pattern match, cut quality, levels/falls, tactile placement, sealant finish, and collar neatness. Use a concise checklist and a photo/redline logbook. Capture NCRs (719) early and correct before replicating errors across the array.
Agree acceptance bands for lippage, joint width, and slope variance in the ITP (714) and escalate unresolved items through the escalation path. This protects programme and avoids late rework that can stress the rating-critical dependencies.
629.9 Final inspection
Client witness and photo evidence (638, 736). Inspection closes HVM bollard delivery.
Invite client/consultant to witness final reinstatement with a structured script (638). Verify cleanliness, joint continuity, no ponding after a short hose test, tactile placement, markings clarity, and that collars are sealed with no trip lips. Take a wide→detail photo set and file geotagged images with test notes.
Close out with updated as-builts (731), the Handover Pack Index (736), and the closeout checklist (739). Ensure maintenance instructions (734) include periodic sealant inspection and cleaning guidance for heads and paving edges.

629 Surface Reinstatement & Finishes/Interfaces — FAQ
How close should paving sit to a bollard sleeve?
Cut paving to a consistent offset that allows a small sealant annulus, not a rigid mortar fillet. The finished collar should be flush within the agreed acceptance band to avoid trip lips and to keep water out of the sleeve perimeter.
How do we avoid water ponding around bollard heads?
Set crossfall away from heads, relieve local ponding edges with subtle re-profiles or micro-channels, and tie into the nearest gully. Reference the site drainage strategy and ensure any inlets have backflow protection where needed.
What tactile/ADA elements are recommended near bollards?
Use detectable warning surfaces with adequate contrast, keep a continuous accessible route respecting the clear-gap rule, and align tactile leading edges with decision points. Confirm sightlines/signage and avoid handlebar traps.
Which documents should capture reinstatement evidence?
Record reinstatement details in the ITP, add geotagged photos in the photo/redline logbook, and update as-builts. Include datasheets/batches for sealants and list anti-ponding checks in the Handover Pack closeout.
