Professional paving and block installation services turn muddy, uneven compounds into clean, durable surfaces that look good and last for decades. Whether you need a driveway, parking bay, walkway or patio, well-laid cabro blocks, pavers and concrete slabs improve drainage, reduce dust and raise property value. Skilled installers prepare the ground correctly, because most paving failures come from poor base work, not poor blocks. This guide covers the services paving companies offer, typical costs, and how to hire a provider you can trust.

Frequently Asked Questions About Paving and Block Installation
1. How long does a paving job take? A typical driveway of 50 to 100 square metres takes three to seven days, depending on weather and base preparation.
2. Which is better: cabro blocks or concrete? Cabro blocks are flexible, easy to repair and allow patterns. Concrete is smooth and strong but can crack, and repairs show.
3. How thick should paving blocks be? Use 60 mm blocks for walkways and patios, and 80 mm or thicker for driveways and areas where heavy vehicles pass.
4. Why do some paved areas sink or become uneven? Poor compaction, weak sub-base material or bad drainage is the usual cause. Proper base preparation prevents this.
5. Can paving be installed over existing surfaces? Sometimes, if the old surface is stable. Most contractors prefer removing loose or cracked material to build a firm base.
6. How do I stop weeds growing between blocks? Use well-compacted joints, polymeric or stabilized sand and regular sweeping. Sealing also helps.
7. Does paving help with drainage? Yes, when sloped correctly. Planned gradients and channels carry water away from buildings and prevent pooling.
8. How long will paving last? Well-installed block paving can last 20 to 30 years or more with basic maintenance.
9. What maintenance does paving need? Sweep regularly, wash occasionally, top up joint sand and reseal every few years if sealed.
10. Do I need approval before paving my compound? In estates or gated communities, check management rules. Where drainage reaches public roads, county requirements may apply.
Why Choose a Verified Professional Paving Contractor
Paving looks simple, but poor workmanship shows up within months as sinking, gaps and standing water. A verified contractor protects your investment. Before you hire, look for:
- Business registration, references and insurance covering workers and property
- Photos or visits to completed projects similar to yours
- Proper equipment, including plate compactors and levelling tools
- Itemized quotes stating block thickness, base depth and materials
- A written warranty on workmanship and a clear payment schedule
Unverified operators often skip compaction, use thin blocks or cut corners on drainage, leaving you with costly repairs.
Build a Surface That Lasts
Good paving improves safety, appearance and property value for decades. Request a site inspection, compare itemized quotes from verified contractors, and confirm the base specification in writing before work begins.
