Question 1

Can a leaning limestone retaining wall be repaired, or does it need rebuilding?

Accepted Answer

It depends on the cause. A small section pushed out by a blocked drain is often a repair. A wall that has moved along its full length, usually because of drainage or footing, is often better rebuilt, because a patch on a bad footing fails again.

Question 2

What is bullnose capping?

Accepted Answer

Capping is the finishing course along the top of a wall, and it sheds water off the top rather than letting it soak into the joints. Bullnose capping has a rounded front edge rather than a square one, a common Perth finish.

Question 3

Is limestone cladding the same as a limestone wall?

Accepted Answer

No. Cladding is a limestone face applied over an existing structure. It is a finish rather than a structural or retaining wall, and it is priced differently.

Question 4

Why does mortar colour matter on a repair?

Accepted Answer

Mortar tinted to match the limestone reads as one material, while default grey mortar shows every joint. On a repair it matters more, because fresh grey mortar against a weathered wall stands out permanently.
