Q & A

What is natural stone used for in construction?
-Natural stone is one of the oldest building materials known to man, used for its wide variation in color, texture, and shades, suitable for various construction projects.
What are the different types of natural stone mentioned in the video?
-The video mentions veined marble, slate, and sandstone as examples of natural stone types.
How is natural stone paving laid on a wet mortar bed according to the video?
-The video explains that a layer of freshly mixed bedding material, roughly 25 to 40 millimeters thick, is spread over an area slightly larger than the paving stone to be laid.
What is the purpose of washing down the back of each paving stone?
-Washing down the back of each paving stone can help with the laying process, possibly by ensuring better adhesion to the mortar bed.
What tools are suggested for spreading the bedding material?
-The video suggests using a shovel or a brick trowel to spread the bedding material.
How should the paving stone be positioned on the bed?
-The paving stone should be positioned allowing for the appropriate joint thickness and then tapped down to the correct fall with a rubber mallet.
What is the recommended joint thickness for the paving stones?
-The suggested layouts in the video allow for an average joint thickness of 10 millimeters.
What is used to fill the joints between the paving stones?
-The joints are filled with a mortar or other pointing material, and in this project, Aspects Easy Joint is used.
How should the Aspects Easy Joint be applied to the paving?
-First, the paving is soaked, then the Easy Joint is wetted to form a slurry, which is swept and washed over the saturated paving into the joints.
What happens to the color of natural stone when it gets wet?
-When natural stone gets wet, the colors intensify and darken, but they return to normal once the paving dries out.
Where can one find more information on laying natural stone?
-More information on laying natural stone can be found in the installation guidelines at www.globalstonepayment.co.uk.

Keywords

💡Natural Stone

Natural stone refers to a variety of rock materials that have been used in construction for thousands of years due to their durability and aesthetic appeal. In the video, natural stone is the primary building material discussed, with a focus on its use in paving. The script mentions different types of natural stone such as veined marble, slate, and sandstone, highlighting the wide variation in color, texture, and shade available.

💡Wet Mortar Bed

A wet mortar bed is a construction technique where a layer of mortar is used as a base to lay paving stones. The script explains how to prepare and use a wet mortar bed for laying natural stone paving, emphasizing its importance for the stability and performance of the paved area.

💡Paving Stone

Paving stones are the individual units used to create a paved surface. The script provides detailed instructions on how to lay these stones on a wet mortar bed, including the preparation of the bed, positioning of the stones, and ensuring the correct joint thickness.

💡Joint Thickness

Joint thickness refers to the space between adjacent paving stones. The video script mentions the importance of allowing for appropriate joint thickness when laying stones, which is crucial for the structural integrity and appearance of the pavement.

💡Rubber Mallet

A rubber mallet is a tool used in construction for tapping down materials without causing damage. In the context of the video, a rubber mallet is used to tap down the paving stones to the correct level after they have been positioned on the mortar bed.

💡Spirit Level

A spirit level is a tool used to check if a surface is level or plumb. The script describes using a spirit level to ensure that the paving stones are laid at the correct level, which is essential for proper drainage and evenness of the paved surface.

💡Mortar

Mortar is a mixture of cement, sand, and water used to bind building blocks together, fill gaps, or provide support. The video script explains the process of mixing mortar for the wet mortar bed and for jointing between paving stones.

💡Easy Joint

Easy Joint is a specific product mentioned in the script for filling the joints between paving stones. The video describes a process where the Easy Joint is soaked to form a slurry and then swept into the joints to provide a finished appearance.

💡Saturated Paving

Saturated paving refers to the process of wetting the paving stones to activate the jointing material. In the script, it is mentioned that the paving should be wetted before applying the Easy Joint, which helps the jointing material adhere properly.

💡Installation Guidelines

Installation guidelines are detailed instructions provided for the proper installation of a product or material. The video script refers to the installation guidelines available on a website for more information on laying natural stone, indicating that there is additional, comprehensive information available beyond what is covered in the video.

💡Long-term Stability

Long-term stability refers to the enduring strength and integrity of a construction project over time. The script notes that judgment must be made at the start of a project regarding the long-term stability of the existing ground, which is crucial for the successful laying of natural stone paving.
