Interlocking Pavers, Kerbs & Sidewalks
NLS Contractors installs precast concrete kerbs, interlocking paving blocks, sidewalks and accessible ramps in Riyadh, Jeddah, Dammam, Khobar and across the Kingdom, on a compacted base with bedding sand and edge restraint. Paving units follow ASTM C936, and handover includes block test certificates, setting-out records and as-builts.
Pedestrian and low-speed vehicle areas are built in precast. Kerbs define the road edge, interlocking paving blocks cover sidewalks, plazas, car parks and forecourts, and ramps make the route accessible. The package covers excavation to formation, base, bedding sand, laying, edge restraint, joint filling and compaction of the finished surface.
Solid concrete interlocking paving units follow ASTM C936, and the block thickness, shape and colour come from the drawings and the approved product submittal. Block test certificates go into the handover file. Kerbs are precast to the sizes in the detail drawings and set on a concrete bed with a haunch where the detail shows one.
The build-up is a compacted subgrade and base, a bedding sand layer screeded to level, blocks laid in the pattern shown, then edge restraint and joint sand. Edge restraint matters most. A paved area without it spreads under traffic and the pattern opens, so the kerb or concrete edge is set first and the blocks are laid up to it.
Falls are set out before the base is laid. Pedestrian areas drain to gullies or channels, and water standing on pavers almost always points to a setting-out error. Accessible ramps follow the gradients and landing dimensions on the drawings and the accessibility requirements of SBC 201 (architectural). Tactile paving goes where the design shows it, at crossings, ramps and stair heads.
Coordination decides the finish. Utility chambers, lighting pole bases, trees and signs set the cutting pattern, and chamber covers are set to the finished level so they do not stand proud or sink. Setting-out records are kept, and levels are surveyed at the end for the as-built. Send the paving plans with levels and falls, the kerb and paver details, the finish and colour schedule, the BOQ areas and lengths, the site city and the programme.

Frequently Asked Questions
What is the difference between interlocking pavers and asphalt?+
Interlocking pavers are individual precast blocks that can be lifted and relaid when a utility is repaired, and they suit pedestrian areas, plazas and car parks. Asphalt is continuous and suits roads and heavy traffic. The design picks one per area.
Why is edge restraint important for paving blocks?+
Without it the blocks spread under traffic and the joints open. A kerb, a concrete edge or a similar restraint holds the pattern in place.
How are falls set for sidewalks?+
From the drawings, toward gullies or channels, and set out before the base and sand are laid. Water standing on pavers usually points to a setting-out error.
Do you provide tactile paving?+
Where the design shows it, at ramps, crossings and stair heads, the tactile units are set as part of the paving to the drawing.
