Crack Repairs

Repair of a complete or incomplete separation

within a single element or between contiguous

elements of constructions.

Cracks in stones or masonry units are very

dangerous and not easily repaired as they affect

the structural integrity and the watertightness of

the unit. To restore the structural integrity it may

be necessary to inject epoxies or install pins. The

restoration of the watertightness is done with

sealant installation or pointing and matching the

color and texture.

Dutchman

A piece of similar material used to replace a

damaged or missing portion of a natural stone or

masonry unit.

The cut is made to fit exactly the shape and size

of the Dutchman allowing the smallest possible

void for the installation of the mortar or epoxy.

A successful Dutchman should be structurally

sound and blend with the repaired unit.

Unit Replacement

Substitution of a damaged unit with a new unit of

the same composition and detail.
