Damp Proofing Services in Eversdal
Looking for professional damp proofing in Eversdal? Waterproofing Durbanville is your local Northern Suburbs team for damp proofing — free on-site inspection, written quote, 5-10 year workmanship guarantee.
Damp proofing tackles moisture problems inside walls — a different beast to roof or balcony waterproofing. In Durbanville the usual suspects are rising damp in older Cape-Dutch and 1970s face-brick homes, penetrating damp driven by Cape winter's south-easter wind on west-facing walls, and lateral damp in split-level houses built into the slope. Our directory connects you with specialists who diagnose the exact pattern with moisture meters and salt-sample analysis before quoting — never blind chemical injection. Compare written quotes from contractors who use BS 6576-spec DPC creams, salt-neutralising primers and breathable salt-resistant render systems suited to Northern Suburbs sandy ground conditions.
We serve Eversdal with same-day quote response and free no-obligation roof inspections. We use approved-applicator systems from Index, Derbigum, Sika and Plascon. All work backed by our 5-10 year workmanship guarantee.

How Damp Proofing Works in Eversdal
Free on-site moisture survey using calibrated moisture meter and, where needed, plaster salt-sample analysis
Diagnose damp pattern — rising (capillary), penetrating (wind-driven), lateral (split-level) or condensation
Hack off contaminated plaster to a height of at least 300mm above the visible tide-mark
Drill 12mm holes at mortar-bed level and inject silane/siloxane chemical DPC cream (BS 6576 spec) where rising damp is confirmed
Apply salt-neutraliser primer to neutralise hygroscopic nitrates and chlorides drawn up by the damp
Re-render with a breathable salt-resistant cement-lime mix (typical SR1 / SR2 spec) — minimum 14-day curing
Re-skim and hand back ready for paint with a breathable mineral or silicate finish (no plastic-vinyl PVA)

What actually causes rising damp in Durbanville homes?
Rising damp is groundwater wicking up through brickwork by capillary action where the original damp-proof course has failed, was never installed, or has been bridged by raised garden beds, paving or external render. Older Durbanville Central homes built before the 1970s often had only a slate or bitumen DPC, both of which break down. Sandy soils in much of the Northern Suburbs hold less water than clay but the high water table after winter rain is enough to drive moisture up affected walls.
How can I tell if it is rising damp or penetrating damp?
Rising damp shows as a horizontal tide-mark that stops at roughly 800mm to 1.2m on internal walls, with paint blistering, white salt crystals on the surface, and a musty smell that lingers. Penetrating damp appears as patchy staining that does not respect a horizontal line — usually on south-east or west-facing walls hit by Cape winter's wind-driven rain, or below a failed window sill. Lateral damp affects a single wall on a split-level home where soil is banked against the inside face. The moisture-meter survey settles the question in 20 minutes.
Will the damp come back after treatment?
If the diagnosis was correct and the chemical DPC, salt-neutraliser and breathable render were all installed to spec, properly treated rising damp does not return. The two failure modes are: (a) the contractor injected DPC for what was actually penetrating or lateral damp — wrong cure, no result; (b) the new plaster was a standard cement-rich PVA-painted system that traps salts and re-blisters in 18 months. Listed contractors who use breathable mineral or silicate paint finishes give 10-year workmanship guarantees on the DPC line itself.
Do you have to remove the existing plaster?
Yes — for any confirmed rising damp case the contaminated plaster must be hacked off to at least 300mm above the visible tide-mark and disposed of. The plaster is full of hygroscopic salts (nitrates, chlorides, sulphates) that pull moisture out of the air on their own, so even after the wall dries the old plaster will keep showing damp patches. Skipping the hack-off and just over-painting is the single most common reason damp 'treatment' fails.
How long does the whole damp proofing job take?
For a typical 6-8 metre internal wall — survey on day one, hack-off and DPC injection on day two, salt-neutraliser primer and re-render on day three. The new plaster then needs 14 days to cure before painting (longer in winter). Total project window: roughly three weeks before you can repaint. Most listed contractors give a written program before starting.
Is chemical DPC injection safe inside a house with kids and pets?
Modern silane/siloxane DPC creams (the kind used by listed specialists) are water-based, low-VOC and odourless once cured. They are injected into the mortar bed below skirting level so there is no surface exposure. The room can be re-occupied the same evening. Older solvent-based fluid injection systems have largely been replaced — if a quote mentions solvent injection, ask why.
