DPC Bridging & Low-Level Damp

Raised paving, bridging render and moisture at the base of external walls.

Discuss your concern

The problem

Damp or staining appears at the foot of a wall, particularly where external ground, render or insulation meets the damp-proof course (DPC).

What an investigation could involve

Review accessible DPC levels, paving and ground heights, render and insulation terminations, internal plaster and the wall-to-floor junction; record visible conditions and appropriate comparative observations.

What you could receive

A concise illustrated report of observed bridging, potential moisture pathways, limitations and practical options such as correcting a confirmed bridge or improving external detailing.

Scope and limitations: A low-level meter reading does not prove rising damp or DPC failure. Concealed construction, cavity debris and the actual moisture source may require further investigation. An appropriate scope, necessary competence, insurance, timing and survey conditions must be established before any paid investigation.
