Repair the fabric,respect the history

Everything you need for conservation-grade masonry repairs — soft lime mortars, irregular stone and fragile fabric worked with minimal vibration and maximum control.

Power tools, conservation manners

Heritage work punishes heavy-handed tools. Percussion cracks old lime mortar beyond the repair, spinning blades overcut irregular joints, and vibration travels through fabric that has stood for centuries.

The ALLSAW's oscillating action cuts with hand-tool sympathy at power-tool speed — following wandering joints, stopping square at the edge of a stone, and leaving the surrounding fabric exactly as it was found.

Technique

Work lime mortar with the Heritage Set

The Heritage Set is made for conservation: narrow kerfs that follow the original joint lines in soft lime mortar, controlled depth so the stone arris is never touched, and low vibration that keeps surrounding fabric stable.

Trade insight

The best conservation work is the kind you can't see.

Heritage repair is judged by what survives around it. Tools that cut only where they're pointed — and nowhere else — are what make invisible repairs possible.

The process

Three steps to invisible conservation

A method that holds from a single joint to a whole listed facade.

  1. Step 1

    Survey & match

    Record the original joint profiles, mortar mix and stone condition — the repair has to match the fabric, not the other way around.

  2. Step 2

    Remove with sympathy

    Follow the original joint lines with the Heritage Set, taking out only failed material and keeping vibration to a minimum.

  3. Step 3

    Reinstate & record

    Rebuild with matched lime mortar and stone, strike joints to the original profile and document the work for the next custodian.
