The Western Cape consumer watchdog receives several hundred paving-related complaints every year, and the pattern is almost always the same: the homeowner paid in full on completion day, the driveway looked perfect for two summers, and by year three the wheel tracks had sunk and the edges had walked sideways — with the contractor's phone long since disconnected [1]. The good news: every one of the shortcuts that causes this failure pattern is visible before you pay. You just have to know what to look for.
This is the same 12-point pre-payment check a good contractor expects you to run on every job before hand-over — written for the homeowner doing their own snag inspection.
| Check | Pass / Fail in… |
|---|---|
| Bond pattern continuous & tight | 10 seconds — visual |
| Concrete edges visible at all perimeters | 20 seconds — walk the line |
| Joint sand filled to within 3mm of top | 30 seconds — finger check |
| No standing water 2 hours after a hose-test | 2 hours — do it |
| Levels within 5mm across a 2m straight edge | 1 minute per check |
Before they start: get the spec in writing
The biggest defence against bad work is a written quote that names the base spec, the paver brand, the joint material, and the warranty. If your quote says "supply and lay paving R220/m²" with no spec lines, you have no contractual leg to stand on when the field starts moving. Insist on:
- Excavation depth (typically 200–250mm below finished level)
- Sub-base material and depth: "150mm compacted G5 in two lifts" is the SANS 1200 MJ baseline [2]
- Bedding sand: "30mm clean river sand"
- Paver: brand, model, thickness (60mm residential, 80mm commercial)
- Bond pattern: herringbone for driveways, stretcher for patios
- Edge restraint: "concrete haunching on all perimeters"
- Joint material: "polymeric sand" or "kiln-dried silica"
- Workmanship warranty: duration and what it covers in writing
During the job: the three site visits that catch 90% of shortcuts
Visit 1 — after excavation, before sub-base
Walk the site and check the excavation depth with a tape measure. From the existing finished level (top of kerb, threshold of garage, etc.) down to the dirt should be your paver thickness plus 30mm bedding sand plus 150mm sub-base — so roughly 240mm for 60mm pavers. Anything less than 200mm and they're planning to skimp the base.
Visit 2 — after sub-base, before bedding sand
The G5 stone should be visibly compacted — if you stand on it, you don't leave a footprint. Ask the crew lead if they did the compaction in two lifts (lay first 75mm, compact, lay second 75mm, compact). The vibrating plate compactor or tandem roller should be on site. If they're trying to compact 150mm in one go, the bottom layer never reaches density. The base should also be cambered for drainage (a 1:80 fall minimum, away from the house).
Visit 3 — during laying
Look for: concrete edge restraints being poured along every perimeter, pavers cut cleanly with a wet saw (not chipped with a hammer), the bond pattern continuous through tight corners, and a 2–5mm gap between pavers for the joint sand. The crew should be using a string line and a level — not eyeballing it.
The 12-point sign-off inspection
On the day they want their money, walk the field with this checklist. Take your time — a R30 000 payment can wait for a 30-minute walk-through.
View red flags as a list
| Red flag | What to check |
|---|---|
| Sub-base too shallow | Less than 150mm compacted G5 stone |
| No edge restraints | Missing concrete haunching on perimeters |
| Empty joint sand | Sand not filled to within 3mm of paver top |
| Wrong paver grade | Below 45 MPa for vehicle driveways |
| No written warranty | Less than 5 years on workmanship in writing |
1. Edge restraints visible everywhere
Walk the entire perimeter. You should see a concrete haunch along every edge — alongside grass, against the house, around the manhole, on either side of the gate. No concrete edge = pavers will walk inside three winters.
2. Bond pattern continuous
Stand at one corner and sight along the bond. The herringbone should be unbroken from corner to corner — no sudden pattern shifts where the laying crew got lazy at a curve. Pattern shifts hide poor cuts.
3. Tight, even joints
Joints should be uniform at 2–5mm across the whole field. A joint that's 12mm in one place and 1mm in another is a sign of pavers thrown in without a string line.
4. Joint sand level
Press your finger into a joint. Sand should be filled to within 3mm of the paver top. Empty joints = washout in the first heavy winter.
5. Joint sand is polymeric or silica, not builder's
Builder's sand is gritty and dark grey. Silica is fine, light grey and almost white. Polymeric has a slightly tacky, gritty feel and often a slight beige or tan tint. If the joint sand is the same as the bedding sand, you have builder's — demand a re-joint.
6. Levels — 2m straight edge test
Lay a 2m aluminium straight edge across the field in a dozen places. The gap under it should never exceed 5mm. Bigger than that and the base wasn't compacted properly — the high spots will telegraph through wear and the low spots will pool water.
7. Drainage falls away from buildings
Pour a 10-litre bucket of water against the threshold of your garage. It should run away from the door, not toward it. Same test at every door, then at the kerb — water should reach the street drain, not pool in the field.
8. The hose test
Run a hose at moderate flow for 5 minutes at the highest point. Wait 2 hours. There should be no standing water anywhere on the field. Puddles deeper than 3mm indicate either drainage failure or base settlement, both worth holding final payment over.
9. Cut pavers, not broken pavers
Around drains, walls and curves, the cut pavers should have a clean saw line — not a jagged hammer-and-bolster fracture. Broken edges admit water and the cut units fail first.
10. No cracked or chipped pavers
Walk the field carefully. Any cracked or chipped pavers should be replaced before sign-off. Don't let "we'll come back next week to swap that one" slide — it never happens.
11. Site clean
All excavation spoil removed. All paver pallets removed. No mortar splatter on the house walls. The site should look ready to use, not ready to clean up.
12. Written warranty handed over
You should leave the sign-off meeting with a signed workmanship warranty document — duration (a minimum of 5 years), what's covered (sinking, edge walk, joint failure), and how to claim. Verbal warranties are worth nothing. SAPMA-accredited contractors carry standardised warranty paperwork [1].
Red flags during quoting
- Deposit demand over 25%. A trustworthy contractor doesn't need 50% up front. Materials are paid on delivery, not booking.
- Cash-only insistence. No EFT means no paper trail.
- No physical address or VAT number. Look the company up on the CIPC register before paying.
- "Lifetime warranty" with no paperwork. Verbal warranties are unenforceable.
- No public liability insurance certificate when asked. If something falls off the bakkie and hits your neighbour's car, you're now the contractor.
- Quote dramatically lower than the others. A 60% discount means 60% less work in the ground — usually base depth and edge concrete.
- Pushy timeline ("if you don't sign today…"). Real contractors are booked weeks out. Anyone who can start tomorrow has just had another client cancel.
If you've already paid and the work has failed
You have a year of statutory CPA recourse against the original contractor for poor workmanship [1]. Send a formal letter of demand, then a complaint to the Western Cape consumer watchdog. SAPMA accreditation also adds a dispute-resolution path. In practice, recovery from a fly-by-night contractor is rare — which is exactly why the pre-payment inspection matters.
If the contractor is unreachable, the contractors in our network can quote a paving repair — usually 30–50% of the original price for a localised relay. These repairs are done routinely across the Peninsula, and the most expensive ones are the ones the homeowner waited two more winters to address.
Common Questions
How do I know if my new paving was installed correctly?
Run the 12-point check above. The non-negotiables are: concrete edge restraints visible on every perimeter, levels within 5mm across a 2m straight edge, no standing water 2 hours after a hose test, polymeric or silica joint sand filled to 3mm below paver top, and a written workmanship warranty.
Should I pay a deposit for paving?
A 10–20% materials deposit is normal once the job is scheduled. Anything over 25% upfront is a red flag. Trustworthy Cape Town paving contractors finance their own materials and bill on milestones.
What's the difference between SANS 1200 and a cheap install?What does SANS 1200 actually require?
SANS 1200 MJ is the South African specification for segmental paving. Key requirements: 150mm compacted G5 sub-base in two lifts, 30mm bedding sand, concrete edge restraints, paver compressive strength minimum 45 MPa for vehicle traffic, and tolerances of ±5mm across a 2m straight edge [2]. Any quote that won't commit to these in writing isn't worth your money.
How long should a paving warranty be?
Five years on workmanship is the SAPMA-accredited minimum — achievable only if the base is built right. Network contractors back their work with a written workmanship warranty — a minimum of 5 years — with terms in your quote. Anything verbal is worthless; insist on a signed document.
What should the bond pattern be on my driveway?
Herringbone (90° or 45°) for any surface that takes vehicle traffic — the interlock resists turning loads. Stretcher bond is fine for footpaths and patios but will walk on a driveway.
Can I withhold final payment if I find problems?
Yes — you have CPA-protected rights to defect remediation before final payment. Document the issues with dated photos, send the snag list in writing, and pay only once the items are resolved. A reputable contractor expects a snag walk-through; an unreputable one will pressure you to pay anyway.
Need a second opinion on a job that doesn't feel right? We'll match you with vetted contractors who do independent paving inspections across the Peninsula — compare quotes, no obligation to use any of them for remediation. Book a paving inspection.
