Damp proofing

Rising damp treatment & chemical DPC injection

Rising damp is capillary moisture pulling through masonry and carrying hygroscopic salts that destroy plaster and paint finishes. Effective remediation combines a new horizontal barrier (typically chemical DPC injection at bed joint level), salt management, and compatible replastering — not a single coat of paint marketed as a miracle cure.

Maverick implements engineer-specified and manufacturer-approved methodologies. We document substrate condition, preparation, and film-build checkpoints — with independent QA available on major commercial scopes — so procurement teams receive defensible records, not marketing claims.

Diagnosis before drilling

Condensation, roof leaks, and lateral subfloor moisture can mimic rising damp. Maverick uses profiled moisture readings, inspection of abutting pavements, and finish removal samples where needed. Misdiagnosis wastes special levies and destroys heritage plaster unnecessarily.

Chemical DPC injection methodology (high level)

Approved silane/siloxane or resin creams are introduced into mortar beds to form a horizontal barrier. Injection spacing, depth, and wall construction (single leaf, cavity, rubble-infill) change the pattern. Replastering uses salt-retardant systems and cavity ventilation advice where applicable.

Sectional-title and HOA communication

Exclusive use gardens, paving bridges over DPC, and retrofitted patios often re-bridge the barrier. Maverick’s reports call out maintenance behaviours that keep warranties defensible under CPA scrutiny.

Typical project profiles (anonymised)

  • Heritage plaster townhouse row

    Injection at regulated centres plus staged replastering preserved skirting architraves while stopping salt bloom recurrence within 12-month monitoring.

  • Ground-floor apartment mistaken for plumbing

    Moisture profiling proved capillary rise; injection plus localized French drain advice stopped repeat tenant insurance claims.

  • Retail fit-out before franchise audit

    Rapid phased damp remediation met landlord handover dates without closing mall trading lanes.

Frequently asked questions

How is rising damp different from waterproofing failures?

Rising damp moves vertically through porous masonry via capillary action, usually absent a functioning DPC. Roof and lateral water ingress are different failure modes with different remedies.

Do you guarantee walls will be dry overnight?

No ethical contractor promises instant drying. Masonry equilibrates slowly; we specify realistic drying timelines and redecoration windows.

Must plaster be removed?

Salt-contaminated plaster often needs removal/replacement systems compatible with injection chemistry. Localised retention is only advised when testing supports it.

What about paint bubbling only in bathrooms?

That may be condensation or leak-driven. Assessments distinguish bathroom HVAC issues from true rising damp.

Can you inject cavity walls?

Cavity construction changes drill patterns and verification. We adjust methodology to manufacturer guidance for double-leaf systems.

Will my paving need lowering?

If external ground bridges the DPC, reducing levels or adding drainage may be advised alongside injection.

Is chemical injection safe indoors?

We manage ventilation, MSDS requirements, and tenant access per OHS files. Low-odour systems exist for occupied spaces where datasheets allow.

How long has Maverick treated rising damp?

Field teams combine damp remediation experience with wider waterproofing and coating knowledge — important when multiple moisture drivers overlap.

Do you issue written specifications?

Yes for trustees and homeowners — scope, products, exclusion zones, and redecoration sequencing are documented.

What is maintenance after treatment?

Groundwater management, replaster integrity, and avoiding re-bridging are typical maintenance themes spelled out in handover notes.
