Line levels (or "string" levels) are a special brand of spirit level used for leveling across longer distances. They can be attached to a tightly pulled string to find level between two stakes in the ground to find level ground. Line levels are a much more cost-conscious alternative to line laser levels, but require a bit more preparation and patience to ensure the job gets done right.
How to Use a String Line Level
- Gather the materials for the job: a line level, a length of string, a tape measure and some means of securing both ends of the string (usually two wooden posts in the ground).
- Secure the string to one side or corner of the area you want leveled.
- Attach the line level to the middle of the string using the small hooks on the line level.
- Pull the string tight while sliding the level up the string within eyeshot.
- Pull tightly enough to avoid any sag in the string. Even the slightest dip in the string will negatively affect your reading.
- Hold the end of the string against the post or wall and adjust up and down until the bubble rests between the black lines on the line level.
- Secure the string.
- You have found level between the two points. You can use these marks on the posts or walls to make further measurements for your home construction projects.
How to Use a Line Level for Pavers
- Dig out a large space for your patio or other paver walkway.
- You need to ensure the ground below your pavers is level, or, slightly graded to allow for better drainage.
- Insert wooden stakes across from each other on each side of the hole.
- Tie each end of a nylon string to the wooden stakes, leaving it loose enough to adjust later.
- Place a line level on the middle of the string.
- Tie the string tightly around one stake.
- Go to the other stake and adjust the string up or down until the bubble on the vial rests between the black lines.
- Take a tape measure or measuring stick and determine the correct distance from string to ground based on your desired depth.
- Take measurements at several points along the string, from string to ground, verifying the depth is correct.
- Dig, fill or tamp the ground where necessary to get to the right depth.
- Repeat the process crossing over the hole in the other direction.
- To further ensure the ground is level, use a long box level or I-beam level along the ground surface.
How to Use a Line Level to Level Ground
- Find a length of string and two wooden stakes.
- Tie one end of string to a wooden stake and hammer it into the ground at the highest elevation in the area.
- Hammer in the second stake across the area you want leveled.
- Pull the string across and tie the other end to the second wooded stake loosely.
- Place the line level on string within eyeshot.
- Pull the string as tight as possible to get the most accurate reading.
- Adjust the string up and down until the bubble sits between the two black lines on the vial.
- Secure the string.
- You have found level between both stakes. Use the marks on the wooden stakes to make measurements for your project.
