Austin Bricklayers and Stonemasons
Bricklayers and stonemasons build walls and structures using bricks, stones, and mortar. Bricklayers do work that is similar to that of stonemasons. They both create attractive and durable surfaces and structures. For example, they create walkways, floors, walls, and fireplaces. A major difference is that stonemasons work with stone rather than brick. They may work with natural cut (granite or marble) or artificial stone (concrete or marble chips).
When building a wall, bricklayers and stonemasons read blueprints or survey the area to see what work needs to be done. They measure distances from points of reference. They calculate angles and use those numbers to align the material horizontally and vertically. Bricklayers and stonemasons mark guides to follow as they lay the material. Stonemasons may also number the rocks in the order that they want to use them.
Bricklayers and stonemasons start by laying out the foundation for the project. They may mix sand, dirt, or powder with water to create the mortar that holds the pieces together. Then they use a trowel to spread the mortar on evenly. Bricklayers and stonemasons lay the bricks or stones on top of the mortar and press and tap them into place. Stonemasons may use crowbars or rubber mallets to move the stones to the right location. At times the trowel may not clear away all excess mortar so workers may use a cleaning solution. Bricklayers and stonemasons usually cut material to fit with other stones or to create a corner. They may use hammers or power saws to cut the material to the needed shape.
Some bricklayers and stonemasons fix old masonry buildings or decorative brickwork. They may remove damaged material, such as bricks and mortar. They also repair the cracks that form as buildings begin to settle. Some walls need extra re inforcement. Bricklayers and stonemasons may add brackets or wire clamps to anchor the stones or bricks to the wall. Once they are finished, they may spray their work with a material that keeps the stone or brick work from breaking down.
Bricklayers start at the corners because they are the most difficult. Only the most experienced bricklayers work on the corners because time, skill, and precision are required. Once the corners are built, less experienced bricklayers fill in the wall between the corners. Hod carriers assist bricklayers. They bring bricks, mix mortar, and set up scaffolding.
Some bricklayers are refractory masons. These workers specialize in installing firebrick or refractory tile. The tiles are installed in high temperature boilers and furnaces. These bricks are able to withstand high temperatures. Many of these workers work in steel mills.
Stonemasons may need to dig a trench to create the foundation of their project. If they use natural rock they may carry it from the truck bed. When stones are too big to carry, they may use a hoist or lift. Stonemasons who work with artificial stones may use molds to create them. They pour the composite material into the mold. After the material dries, they position it along the wall and remove the mold. They may also smooth or polish the rocks¿ surface to match the other rocks.
Bricklayers and Stonemasons perform the following activities on a regular basis:
- Examine blueprint or structure to see what work needs to be done.
- Measure distance from reference points using levels or plumb line. Mark reference guides.
- Calculate angles and determine vertical and horizontal alignment.
- Lay out wall pattern or foundation.
- Mix mortar or grout.
- Apply and spread mortar on foundation.
- Lay and align bricks or stones following guidelines.
- Remove excess mortar with hand tools or acid.
- Break or cut material to fit.
- Fasten or fuse material to keep it from falling apart.
- Remove damaged brick or mortar or repair cracks.
- Spray material to protect against wear.
- Dig trench for foundation of project.
- Fill molds with composition-stone mixture.
- Position structure along wall and remove mold.
- Remove rock sections from truck bed. May use a hoist when rocks are too big to lift.
- Smooth or polish rock surface.
