Basement walls and below-ground moisture

Damp basements and garages in Alicante

Does a wall below ground stay wet or leak after rain? We assess the contact with the ground, wall-to-floor joints and accessible drainage. Waterproofing from inside is only proposed when the substrate and water conditions allow it.

Initial guidance from photos is free. An on-site technical visit costs €85 including VAT, booked and paid in advance. The full €85 is credited if we carry out the subsequent work.

Understanding the problem

Find out how water reaches the underground wall

Salts, peeling finishes and free water can have different causes. The position of the room relative to the surrounding ground is important.

01

Retaining walls

Moisture can come through the side of a buried wall. We consider external ground levels and access before choosing an approach.

02

Wall-to-floor joints

Water may concentrate at the junction between the floor slab and wall. Covering the main wall while ignoring that joint can leave the problem unresolved.

03

Cracks and penetrations

Pipes, joints and local defects are assessed individually. Active water and substrate condition affect the repair sequence.

04

Condensation in enclosed rooms

Limited ventilation can coexist with water ingress. The two need to be distinguished before installing a lining or coating.

Inspection on site

Assess the limits of an internal intervention

When the outside face cannot be reached, we review whether an internal system is viable and which areas must be included. A decorative lining does not establish control of the water source.

  • Ground levels and rain-related changes
  • Wall, slab, joints and service penetrations
  • Loose finishes, salts and accessible substrate
  • External access and need for further checks

One meter reading cannot establish the cause. We compare the readings with the visible pattern, surroundings and history of the problem.

Common questions

Before arranging repairs

Can the wall be treated from inside?

In some cases, with a compatible system and adequate preparation. It is not a universal solution for every buried wall.

Should I cover the damp with plasterboard?

First establish the source and how the wall will dry. A lining may hide ongoing water ingress.

Do you also inspect lift pits?

We assess the construction-related water ingress, with access and lift equipment matters coordinated by the lift maintenance company.

Start with photos, the location and what happens

We check whether the issue is within our scope and whether a visit would help. Sending a message does not book or charge for a visit.

Send the town and photos in writing. We will agree the language of the visit before booking.
