Subsidence & Underpinning in Marchmont

Why Marchmont keeps us busy

Every working week we are somewhere in Marchmont, often within a short walk of the Meadows and Bruntsfield Links. The building stock here has its own character, and the ground beneath it has its own habits. Knowing both is the difference between a fix that lasts and a repair you have to revisit.

Marchmont's red sandstone tenements are tall, heavy and largely well-founded, but blocked common drains in the back greens cause more underpinning calls than the buildings themselves. Drainage CCTV is almost always step one here.

Subsidence & Underpinning done properly

Cracks above lintels widen month by month. Skirting opens up. The bay window sits lower than the rest of the front wall. Subsidence rarely fixes itself. Foundations keep moving until the cause is dealt with, and the longer that takes, the more decoration, plaster and joinery has to come out alongside the structural work.

Find the cause first, then design an underpinning scheme to suit the building. Mass concrete suits older shallow strip foundations. Mini-piles take the load deeper when ground is soft or made up. Either way, a chartered engineer signs the design before we dig.

Three things Marchmont owners get from us

• Local context. We know which streets in Marchmont sit on made ground, which ones drain badly, and which ones have a tree problem. The first visit reflects that.
• Engineer-signed work. Every scheme we put in is signed off by a chartered structural engineer before any tools come out of the van.
• Reports your insurer recognises. Cause, scheme, photographs, costs. The format the loss adjusters in this city already know.
