Belza Préfa

Precast concrete specialist for the construction industry: structures, drainage and civil works.

Belza Préfa specialises in precast concrete for the construction industry: structures, drainage and civil works. The company designs both standard and custom elements — beams, precast slabs, kerbs, pipes — that shorten site schedules and guarantee consistent industrial quality.

From trading to the plant

Belza Préfa was founded in 2010, two years after the group’s first aggregate mine, and marked the start of its trading activity. The first plant opened in 2012.

Standard and made to measure

The catalogue covers everyday building and road-work requirements. Anything outside it is designed to order, with support from the design office.

Coverage and lead times

Belza Préfa delivers across the whole of Morocco, within 24 to 72 hours depending on area and availability. Haulage is handled by Belza Logistics, the group’s transport subsidiary.

Product and service descriptions

Product names, grades and services are those supplied by the client. The sentences describing what they are for are written by the agency: they explain what that type of element does, without stating a dimension, weight, strength class or standard. Those characteristics remain to be supplied by the subsidiary before going live.

The catalogue, product by product

Products are grouped by family. Each one carries what it is for on a construction site.

15 products · 3 families

Structure

The load-bearing elements of the building, cast in the plant then lifted and assembled on site.

Beams
Horizontal load-bearing element. It takes the loads of a floor or roof and carries them to the columns.
Joists
Load-bearing floor element. Laid across the span, it receives the hollow blocks and then the compression slab poured over them.
Precast slabs
Thin precast slab that acts both as formwork and as the lower reinforcement of the floor cast on site.
Hollow blocks
Infill element laid between two joists. It closes the floor and lightens it.
Columns
Vertical load-bearing element. It carries the loads taken by the beams down to the foundations.
Wall panels
Vertical load-bearing or facade panel, delivered ready to lift.
Concrete blocks
Masonry blocks laid as load-bearing or infill walls. The basis of the structural works.

Drainage

Buried networks — water disposal and cable runs.

Pipes
Buried conduit for foul or surface water disposal.
Culverts
Large-diameter conduit for crossings: carrying water under a road or an embankment.
Inspection chambers
Access structure for the buried network. It allows inspection and clearing between two sections.
Cable draw chambers
Buried structure on the dry network. Cables are drawn and jointed there without reopening the trench.

Roads and services

The road and its surroundings, from the carriageway edge to the footway.

Kerbs
It separates carriageway from footway and holds the road layers laterally.
Gutters
It collects run-off along the carriageway and carries it to the network.
Paving slabs
Surfacing slab for footways, terraces and pedestrian routes.
Interlocking pavers
A paver whose shape locks into its neighbours: the surface holds without binder, and is repaired one paver at a time.

Services

What comes with the product, from design to delivery.

Design office
Design of bespoke items, upstream of production, when the standard catalogue does not cover the need.
Technical support
Support to site teams on selecting elements and installing them.
Laboratory
Testing of materials and of the elements produced.
