Damp proofing in the United States
Stop moisture at the source before it reaches your living space.
What the work involves
Damp proofing addresses moisture entering a structure through walls, floors, or around the foundation perimeter. A specialist identifies the source first, whether that is groundwater pressing against a basement wall, a failed waterproof coating, or a gap where water sits against the building, then applies the appropriate barrier or drainage solution.
The work typically involves applying a waterproof membrane or coating to the affected surface, installing drainage channels to redirect water, or injecting a chemical damp-proof course into the masonry. A free quote is available once the specialist has reviewed the property details.

How the work gets done
Initial assessment
The specialist examines each affected wall, floor and ceiling, recording moisture readings and noting the height and pattern of any staining or efflorescence.
Source identification
Meter readings, salt analysis and a check of external ground levels, gutters and pointing narrow down whether moisture is rising from the ground, penetrating from outside or arriving from a leak.
Treatment application
The appropriate damp-proofing method is applied, whether a chemical injection course, a waterproof render coat or a drainage membrane, according to the wall type and moisture source confirmed.
Surface reinstatement
Treated surfaces are replastered or made good, drill holes are filled flush, and a written record of the work carried out is left with the homeowner.

What affects damp proofing work
Surface preparation
Existing plaster, paint, and loose render are removed before any treatment is applied so the product bonds directly to the masonry.
Interior versus exterior treatment
Some moisture problems are best addressed from outside the wall; others require internal tanking. A specialist will identify which approach suits the source of the water.
Drainage interaction
Where ground water is the source, damp proofing alone may not be enough. Improving drainage around the perimeter often reduces the pressure that drives moisture through walls in the first place.
Making good after treatment
Once the treatment has cured, walls are re-plastered or re-rendered. The finish coat is usually a sand and cement mix that is compatible with the damp proofing layer beneath it.
