Moisture Control & Internal Waterproofing
Moisture Proof
Moisture Proof reduces moisture vapour movement within concrete, helping prevent flooring failures related to high moisture conditions.
Available Sizes
Key Features
- Reduces moisture vapour transmission (MVT)
- Supports flooring adhesives and coverings
- Helps stabilise new and existing slabs
- Penetrating, non-film-forming
- Improves long-term flooring performance
Ideal For
- slabs receiving vinyl, timber, carpet or tiles
- commercial flooring installations
- moisture-sensitive environments
- remediation of older slabs where moisture is present
How It Works
The treatment penetrates the slab and reacts with available minerals, reducing pathways for moisture vapour. This helps stabilise the slab prior to flooring installation.
Application
- 1
Ensure the surface is clean and free of coatings.
- 2
Apply evenly with a low-pressure sprayer.
- 3
Keep the surface wet for 20-30 minutes.
- 4
Work the product in with a soft broom if required.
- 5
Allow to dry completely before applying adhesives or coverings.
Coverage & Drying Times
Coverage
Typically 5-10 m² per litre, depending on porosity.
Drying & Curing
- Dry to touch
- 2-3 hours
- Flooring installation
- typically next day
Compatibility
- Can be used under most flooring adhesives (always check manufacturer guidance)
- Suitable for new and old concrete
- Not effective on sealed or coated surfaces
- Does not replace surface membranes where required by code
Limitations
- Very high moisture slabs may require additional treatments
- Not a vapour barrier membrane
Safety & Handling
Use standard PPE during application.

Start by identifying what you want the concrete to do: become harder, resist moisture, repel stains, or improve appearance. Each DuraCore product is designed around one of these outcomes.
- Hardness / reduced dusting → choose a densifier (DensiCrete or Densi Anti-Micro)
- Moisture control → choose Moisture Proof or Moisture Prevention depending on timing
- Water/oil repellency → choose a repeller (Repeller or Densi-Repeller)
- Improved appearance/surface finish → choose AquaSeal or Lustre Crete
A densifier strengthens concrete internally, while a moisture control treatment reduces moisture movement within the slab.
- Densifiers create more C-S-H inside the slab → harder, less dusty, better wear resistance
- Moisture treatments reduce vapour pathways → stabilise slabs for flooring and reduce moisture-related failures
- They solve different problems and can be used together in some cases
Densifiers work inside the concrete to make it harder. Sealers work on the surface to protect appearance and improve cleanability.
- Densifiers: penetrate and chemically harden the slab
- Sealers: create a protective film that enhances the look and provides light surface protection
- They are often used together in polished or decorative concrete systems
Use a penetrating repeller when you want protection without altering the concrete's appearance or sheen.
- you want a natural finish
- the surface receives water, oil, or food spills
- UV stability is needed (outdoors)
- slip resistance must be maintained
- you want visual enhancement
- you want a subtle sheen or finished look
A penetrating repeller is usually the best option for outdoor areas, especially driveways.
- Repeller: best protection against water, oil, and everyday contaminants
- Densi-Repeller: good option if you also want increased hardness
- AquaSeal or Lustre Crete: use only if you want an enhanced appearance (but film-formers may require more maintenance outdoors)
