Description –flexible waterproofing membrane

Drizoro Maxseal Flex is a two-component product producing a continuous cementitious flexible waterproofing membrane.
Component “A” is a water-based special acrylic resin and
Component “B”, is a mortar based mixture of special cements, additives and well-graded aggregates.

Once applied and cured, Drizoro Maxseal Flex provides a non-toxic, flexible and waterproof coating with very high adhesion on those common substrates in construction concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks, Hebel etc.

Drizoro Maxseal Flex – for potable water

Applications

• Waterproofing and protection of water retaining structures, such as drinking water tanks, reservoirs, water mains and swimming pools.
• Waterproofing of below-grade structures like basements, retaining walls, foundations, tunnels, and galleries subjected to both positive or negative high water pressure.
• Internal and external waterproofing and protection of new and old buildings, and facades against dampness, rain, pollution and an aggressive environment.
• Waterproofing and protection of concrete against carbonation, and chlorine penetration in public works, irrigation channels, dams, retaining walls and water treatment plants, bridges, etc.
• Tile fixing and waterproofing of roofs under tiles and pavement in terraces, balconies, bathrooms, kitchens and other wet rooms in hotels, hospitals, offices and residential buildings, for indoor or outdoor use.
• Waterproofing of window boxes, gardens and other surfaces subject to root penetration.
• Water retention structures.

Advantages and Benefits of Drizoro Maxseal Flex:

Here are 16 Benefits of Drizoro Maxseal Flex

1. Provides a fully flexible waterproofing membrane that ensures complete waterproofing in the most severe conditions,
2. even seals in the presence of high negative or positive water pressure.
3. Covers shrinkage and hairline cracks in the concrete.
4. Acts as an anti-fracture membrane between the substrate and other finishing coats.
5. Excellent protection for concrete, being both a CO2 and chlorine (Cl-) barrier and thereby preventing carbonation and electrochemical corrosion.
6. Permeable to water vapour, allows the substrate to breathe.
7. Resistant to abrasion and is UV stable.
8. Withstands atmospheric pollution, corrosive effects of saltwater and freeze/thaw cycles.
9. Resists hydrostatic negative and positive pressure from groundwater when used for interior underground applications.
10. Excellent adhesion and easy to use.
11. Essential to wet the surface.
12. NO Bonding Agents. No Primers.
13. Non-toxic and chloride free. Suitable for contact with potable water.
14. Longer lasting than other coatings, avoiding maintenance costs.
15. Environmentally friendly.
16. Withstands root penetration, when properly reinforced with fibreglass mesh.

Important Notice:

Surface preparation:

Ensure your desired surface is sound. Clean the surface to remove all traces of paint, loose particles, dust, grease, mould release compounds, gypsum, and efflorescence.

It is the responsibility of the applicator to determine the presence of (salt) efflorescence prior to application. Remove efflorescence using Efflorescence Rid and apply Sealtight Clear to the affected areas to block the salt from penetrating.

Important:   Drizoro Maxseal Flex can only be applied to a wet surface. N0 primers. Just a clean damp surface. Treat areas where salt treatment are to be carried out.

Apply Drizoro Maxseal Flex flexible waterproofing membrane in these areas while the surface is still wet with Sealtight Clear.*

Repair any damaged concrete defects in advance. Patch all holes, voids and honeycombs. Open cracks to approximately 2 cm. in depth.

Exposed steel bars must be cleaned and patched with Drizoro Maxrest. Minimum 1 cm. minimum thickness. Treat steel bars with the oxide converter Drizoro Maxrest Passive (Tdb.o12).

Prior to the application of renders, adhesives etc…Recommended to apply a scratch/flick coat mixed with latex/acrylic.

Drizoro Maxseal Flex is supplied as two pre-weighed components. Pour the resin, component A, into a clean container and add the powder, component B, gradually, while mixing with a low-speed mixing drill (400 – 600 rpm). Mix to achieve a lump free homogenous mixture.

DO NOT add water and keep the liquid/powder ratio as per the packages supplied. Depending on the existing temperature and R.H. climate conditions, pot life expectancy will be between 30 minutes and one hour.

Application.

Apply Drizoro Maxseal Flex with a fibre type brush or broom such as MAXBRUSH or MAXBROOM, or by trowel. Large areas of Drizoro Maxseal Flex can be sprayed, the nozzle size is 3-4 mm. Spraying pressure is between 3.5 and 5.0 bar. When you spray Maxseal Flex. Drizoro recommends that you finish the first coat using a broom. Broom or brush presses coating into any voids completing coverage.

Consumption:  

For extreme situations requiring full 9 bar positive and 4 bar, Negative waterproofing, Apply two coats, using 1 – 1,5 kg/m2 of Drizoro Maxseal Flex per coat and allow a minimum of 16 hours and a maximum of 3 days between applications.

Prior to application thoroughly wash down and saturate the surface, but do not leave free-standing water. Thickness per layer should be 1 mm. approximately, it is very important to avoid very thin or, thick applications.
Wet the surface again prior to the application of the second coat.
