Who Builds Rock Walls

Masons are the ones who will build your rock walls, whether it is a mortar wall or dry stack walls. Some stonemasons specialize in this job, and they are the ones you should use. The best rock wall masons can be found on Hawaii Big Island. This area is a volcanic region, which means lava rocks are in abundance on the island. This material can be used to build all kinds of rock walls and terraces that you may have in mind. Over generations, Hawaiians, Samoans, and Tongans masons have built these walls and passed the skills down.

Methods of Building Rock Walls

Two methods are commonly used. They are:

Mortar Wall Method: This is when cement is used to join the rocks and give the wall a firmer hold. Some masons are experts in this particular type of rock wall, and you will easily find one because this method is the most common method for building rock walls.

Dry Stack Method: Rock walls are one of the oldest man made creations, and people have been building them long before cement was discovered. The method used for making these rock walls and which is still in use today is dry stacking. The Hawaiian name for this type of wall is Uhau Huma Pohaku. This type of rock requires more expertise than mortar walls because the wall structure usually determines how long it stands. When properly built, dry stack rock walls can last for centuries or even millenniums. Most of the iconic walls today were made using dry stack methods. If you want a rock wall that looks completely natural, this type of rock wall is the best choice.
