How to install gravel base for putting greens and artificial grass.

Compacted "1/4 inch - Minus" gravel

Artificial grass is water, time, and money efficient. Are you contemplating giving your property artificial turf? There are more factors at play than just turf. You’ll also need an underbase. Learn more about the three different types of artificial grass sub-bases.

In contrast to conventional lawns, artificial grass is not frequently employed in grassy regions. It is also used around pools, patios, and concrete decks. The area underneath that artificial grass is known as the sub-base. Pick the best sub-base for the most stunning artificial grass.

Most grasslands have soil, and that soil swells and varies during cold and hot, dry and rainy circumstances. If you do not take notice of this sub-foundation, your grass can develop creases, holes, or weak patches. Surfaces become uneven as a result.

Install a sub-base to replace the natural soil’s vast surface with one that is less expansive. You can use your lawn for many years if it is installed properly.

There are several different sub-bases:

  • Crushed Miscellaneous Base (CMB)
  • Class II road base
  • Decomposed granite (DG)

CMB is composed of recycled concrete or asphalt mixed with sand and gravel ranging in size from 3/4″ to fine sand.

The most costly CMB variation is the Class II road base. Due to extensive testing, it is more costly. The Class II road base is not necessary for the majority of individuals. 

The DG is made of granite. It is worn and breaks into minuscule, fragile rock fragments that are a combination of sand, gravel, and clay particles the size of silt.

The CMB is the option that is most frequently used for landscaping. It’s inexpensive and simple to compress. Though more expensive than CMB, DG results in a smoother look.

The DG option is perfect if you’re constructing putt courses with artificial turf. Compared to CMB, DG is less porous.
