Understanding what paving contractors do, why the base under the pavers matters more than the pavers themselves, and how a professional installation stays flat while a cheap one sinks.
Paving contractors install driveways, patios, walkways and pool surrounds — excavating and compacting the base, laying brick, cement, cobble or natural stone pavers, and finishing with the edge restraints and drainage falls that keep a paved surface flat and functional for decades.
Paving contractors install and repair the hard outdoor surfaces around a home — driveways, patios, walkways, parking areas and pool surrounds. The visible part of the job is laying pavers; the part that determines whether the surface lasts is everything underneath: excavation to the right depth, a properly compacted base, correct falls so water drains away from the house, and solid edge restraints holding the whole surface together. A paved driveway done properly carries vehicles for twenty years or more. Done cheaply, it develops ruts and sunken patches within two winters — and fixing failed paving means lifting and redoing it, not patching it.
Paving work splits into new installations that add usable outdoor space and property value, and repairs where existing paving has sunk, loosened or stopped draining. Recognising early signs of paving failure — a few rocking pavers, joint sand washing out, water starting to pool — allows repair before the base erodes and a section needs full relaying.
Professional paving is a layered system, and each layer has a job. The difference between a surface that stays flat under vehicles and one that ruts is almost entirely in the preparation you never see once the pavers are down.
The contractor excavates to a depth suited to the traffic the surface will carry — deeper for driveways than for footpaths — removes soft or organic material, and builds up a base layer of crusher run or similar material compacted in layers with a plate compactor or roller. On clay soils, common across parts of the Western Cape, the base is what stops seasonal ground movement from telegraphing through to the surface. Skimping here is the single most common cause of paving failure.
Before laying, the contractor sets levels so the finished surface falls away from buildings and towards drainage points — typically a gradient of around 1:60 to 1:80. Pavers are laid on a screeded bed of river sand in the chosen pattern, with bond patterns like herringbone used on driveways because they interlock and resist the turning forces of vehicle wheels far better than straight stack patterns.
Paving works as a system only when the edges are held. Contractors set edge courses in concrete haunching so the field of pavers cannot creep sideways under load — failed or missing edge restraints are why cheap driveways break up from the outside in. Once laid, joint sand is swept into the gaps and the whole surface is compacted, locking the pavers together into a single load-spreading surface.
The workhorse of South African paving — bevel and interlocking cement blocks in various colours and thicknesses. Cost-effective, durable, and available in 50mm for pedestrian areas and 60mm–80mm for driveways.
Fired clay pavers hold their colour permanently, suit traditional and Winelands-style homes, and are extremely hard-wearing. They cost more than cement but never fade or need sealing.
Cobble-style pavers give a textured, classic finish popular for driveways and entrances. Simulated cobbles deliver the look at a lower cost than cut stone.
Sandstone, granite and flagstone create premium patios and pool surrounds. Material and laying costs are higher, and correct bedding matters even more because of the irregular thickness of natural stone.
Paving looks like a simple job — which is why so much of it is done badly. A surface laid on poorly compacted ground will sink where wheels run, pool water against the house, and shed its edges. Because paving is a system, localised failure spreads: once edges give way or the base erodes, the interlock is lost and the deterioration accelerates. Professional contractors get the invisible layers right, so the visible layer stays flat.

Site Visit and Quote: The contractor measures the area, assesses soil and drainage, discusses paver options, and provides a written quote per square metre with the base specification stated.
Excavation and Base: The area is dug out, soft spots removed, and the base material placed and compacted in layers to the specified depth.
Laying: Falls are set, bedding sand is screeded, and pavers are laid in the agreed pattern with cuts done neatly at edges and around obstacles.
Edges and Jointing: Edge courses are set in concrete, joint sand is swept in, and the surface is compacted to lock the pavers together.
Cleanup and Handover: Excess material and rubble are removed, the surface is cleaned, and any maintenance guidance — like topping up joint sand after the first rains — is explained.
