A typical high-set house

High-set vs 2 storey house differences

The following photos show indications of seepage and rising damp to single and double brick walls (no cavity) of high-set houses.

These problems are the reasons why high-set houses are not suitable for conversion to habitable areas and the brick walls must not be covered with any type of material.

High-set vs 2 storey house differences.

A purpose built 2 storey house has been designed and constructed to stop seepage and rising damp affecting its inhabitants.

The following items are fitted during construction.

  • Rebate to the slab edge.
  • Vapor barrier fitted below the slab.
  • Damp-course barriers, fitted just below the slab level.
  • Weep-holes fitted to the lower section of the walls.
  • Cavity between outer brick and inner wall.

These necessary items cannot be effectively and economically fitted after the building has been constructed.

High-set vs 2 storey houses   

Some examples:

You can clearly see indications of rising damp also lack of weep-holes, therefore the walls are unlikely to have damp-course barriers.

High-set vs 2 storey house. Be warned!

  • Some builders claim this can be overcome with water-proof render applied to exterior of the brick walls.
  • This may help stop some seepage (for the short term) but will not stop seepage and rising damp!

Never cover the inside of a single brick wall with any type of material otherwise this will trap moisture and cause serious problems.

If your builder disagrees with any of these comments, demand written guarantees!
