The Stone & Worktop Glossary


Decisions are more informed with knowledge!

The jargon used in defining stone terms can often become quite convoluted. The purpose of this section is to try to offer a clear explanation, in layman’s English, of the most common definitions relating to stone, worktops as a whole and their fabrication.

If you are looking for an explanation of a term not contained here please feel free to contact us and we will be happy to try to assist you.

Stone And Worktop Terms Beginning With The Letter W


An inside veneer of stone less than full wall height.

Wall Plate

A straight part anchored to a stonework wall to which other structural elements may be attached. Also called head plate.

Wall Tie

A bonder or metal piece which connects wythes of stonework to each other or to other materials.

Wall Tie Cavity

An inflexible, corrosion-resistant metal tie which bonds two wythes of a cavity wall. It is typically steel, 5mm in diameter and formed in a "Z" shape. 

Wall, bearing

A wall supporting a upright load in addition to it own mass. 

Wall, Cavity

A wall in which the inner and outer wythes are spaced by an air gap but tied together with metal ties. 

Wall, Composite

A wall in which the facing and backing are of different materials and linked together with bond stones to exert a common reaction under weight. 

Wall, Veneer Or Faced

A wall in which fine facing and the backing are of different materials but not so bonded as to exert a common reaction under load. 

Wall, Wind (Wined)

A twisting deform from cutting slabs in the gang saws. 

Wall, Wythe

The inner or outer part of a cavity wall.  


One of the sides of a room or building connection floor and ceiling or foundation and roof:  


Usually a condition experienced only in flagging or flagstone materials; very ordinary with flagstone materials that are taken from the earth and used in their natural state. To stop warping in stones it would be necessary to further finish the material such as machining, sand rubbing, honing, or polishing. 

Warped Walls

Usually a condition experienced only in flagging or flagstone materials; very common with flagstone materials that are taken from the ground and used in their natural state. To eliminate warping in stones it would be necessary to further finish the material, by methods such as machining, sand rubbing, honing or polishing.  


A gradient area or the area water will move over.

Water Bar

Usually a strip in a regret in window sill and stone below to prevent water passage. 

Water Base

Water repellents and latex paint coatings containing water soluble or water dispersible binders.

Water Of Crystallization

The additional water required to help in the crystallization process when forming a hydrate (mortar, cement, concrete, plaster, etc…) When the hydrate gives up this excess water, at ambient temperatures, the result is a surface deposit known as efflorescence or discoloration. 

Water Repellent

Any of several types of clear liquids used to render stonework wall less absorptive. These treatments are said to preserve a material’s ability to breathe away moisture, as distinct from “sealer” which form impermeable, non-breathing coatings.

Water Retentivity

The property of a mortar which prevents the quick loss of water to stonework units of high suction. It put a stop to bleeding or water gain when mortar is in contact with relatively impermeable units.

Water Table

A nonstop course of building units on the exterior of a wall, near the ground, with a level projection or ledge. It is frequently shaped with a slope and a drip to limit the amount of water running over the wall or surface below.


A coating used to treat the surface of the substrate, stopping water from penatrating, but allowing water vapour transmission, 


A industry expression used in fabrication of inside marble to describe the process of filling natural empty space with cements, shellac, or other materials. 


The synthetic removal of material, or impairment of the stone surface finish, through friction or shock.

Weathered Joint

A gradient to the exterior of the upper part of a joint to shed water.


Natural change by either chemical or mechanical process due to the action of the atmosphere, surface waters, soil and other ground waters, or to temperature transform. Changes by weathering are not necessarily unwanted or damaging.


The cross wall linking the face shells of a hollow stonework unit. 


Splitting of stone by driving wedges into planes of weak point.

Weep Holes

An gap for drainage in veneer joints or in the structural components supporting the veneer. 


The ability of a coating to flow out, spread, or go in a substrate.


A chalk pigment in paint and putty. 


One who buys dimensional stone in all forms for resale to the trade. 

Wind (Wined)

A deform in a semi-finished stone slab to be removed by further fabrication. 

Windown Sill

The base section of a window frame and/or the bottom section of an exterior masonry window opening.

Window Stool

A thin shelf fitted across the lower part on the inside of a window aperture.

Wire Saw

A sawing device consisting of one or more wire cables, moving over pulleys used to cut natural stone into blocks and slabs by tension and fed slurry of an abrasive and water cuts by abrasion. 

Wire Sawn

A means of cutting stone by passing a twisted, multi-strand wire over the stone, and immersing the wire in a slurry of abrasive material. 

Wrap Around

The ability of a coating to cover all areas of the substrate to which it is applied, including edges. Also, the effect of an electrostatic charge upon a coating and the ability of the coating to cover all exposed conductive areas.


A stonework wall, one stone or brick deep, that either faces a back-up or is a back-up wall and secured to its neighboring wythes by bond stone or grout; or forms either half of a cavity wall,
