Get matched with top pavers and hardscaping pros in Crystal City, TX

If you’re installing pavers over an existing concrete slab, you don’t need to affix the majority of the pavers, but you should use a polyurethane-based adhesive on the border pavers. Polyurethane will expand and contract with temperature changes, which will help keep the pavers firmly in place throughout the year. It’s also strong enough to stand up to foot traffic. You’ll use polymeric sand between the non-border pavers to keep them in place and prevent shifting.

The lifespan of pavers varies based on many factors. Material is the key component, with concrete, stone, and brick pavers lasting up to 100 years, while clay pavers usually only last around 25 years. To maximize your pavers’ lifespan, you should keep your paver patio or walkway clean, add sealant every few years, and keep the joints sealed with polymeric sand as needed.

While water-related pressure caused by poor drainage is one common cause of paver cracking, other factors can include ground movement beneath pavers, heavy loads and wear and tear over the pavers, and climates with constant freeze-thaw cycles. In general, pavers should be resealed every three to five years to prevent cracking.

Installing a heated driveway is often worth the cost because it will significantly boost a home's value, especially in areas that often suffer from heavy snow and freezing temperatures. Even if you only install the basic components and never activate the heating system yourself, giving the future buyer an option to finish the system can still increase your home’s value.
