Get matched with top deck maintenance specialists in Lilburn, GA

Before installing a deck, you must build a base for the deck to rest upon, often made of compacted soil or gravel. While gravel is an optional material, it helps with drainage. Some contractors also recommend installing a weed control membrane, which helps provide a solid foundation for the frame. In the case of an elevated deck, a pro will often lay down a concrete slab as a foundation. 

The best base materials for a ground-level or floating deck are typically gravel and crushed stone (also known as landscaping rocks). These options are inexpensive, provide excellent drainage, prevent weeds, and help minimize moisture buildup, which reduces shifting and rotting. For added stability and to evenly distribute the weight, you can use concrete deck blocks or pavers. While more expensive, concrete blocks and pavers offer a sturdier base than gravel or crushed stone alone.

Decks are generally more expensive to build because they require elevating and railings. The difference between decks and patios is that decks are elevated, while patios are usually on the ground level. Plus, decks are usually made of wood and need more maintenance than most patios. However, decks and patios serve the same purpose, providing outdoor space for you to enjoy.

The choice between Trex, a brand of composite decking, and PVC decking depends on your priorities regarding budget, appearance, and environmental impact. Both materials are durable and resistant to moisture and insects. Trex is often considered more eco-friendly because it contains recycled wood and plastic and is 25% recyclable, while PVC is fully synthetic and harder to recycle. Aesthetically, Trex is designed to look more like real wood, whereas PVC often has a glossier, more plastic-like finish. In terms of cost, Trex is typically less expensive than PVC.
