Drizoro Maxseal Super is a special waterproofing coating made of a mixture of cements, carefully controlled aggregates and special organic and inorganic additives. Its special formula improves the osmotic effect of the application allowing the penetration into the concrete through its capillary system. The product crystallizes inside sealing, waterproofing and protecting the concrete structure. It has been designed to be applied on fresh or set concrete, pre-cast concrete, concrete blocks or cement plasters but is also suitable for applications in bricks and masonry. It is often used as a replacement for Bentonite clay membranes.

1.1. ADVANTAGES of Drizoro Maxseal® SUPER

This cement-based osmotic system is a one-component, cement-based, waterproof and protective coating applied in thin layers. i.e. up to 1 mm per layer, which achieves the following properties:

1. Excellent waterproofing properties. Withstands very high positive and negative hydrostatic pressure.
2. High adhesion and compatibility with common substrates used in construction.
3. NO bonding or priming agent required. Apply only on a wet or damp surface.
4. It fills and seals the pores of the substrate and becomes part of the structure of the surface.
5. Is a continuous waterproofing membrane. No joints or overlap connections required. – leaking risk is much reduced or completely avoided.
6. Permeable to water vapour – it allows the substrate to breathe. A vapour barrier is not formed.
7. High resistant to abrasion and UV rays. High durability, similar to concrete.
8. Excellent chemical protection of concrete against atmospheric pollution, de-icing salts, soil salts, chlorides, seawater and carbon dioxide,
9. Resists the carbonation and electrolytic chemical corrosion of reinforcements.
10. No solvents or toxic components are used.
11. Environmentally friendly and it is a suitable coating for drinking water tanks
12. Manual applications are QUICK and Easy. Spraying will be faster. Saving labour and less work required.
13. Drizoro Maxseal® SUPER is non-toxic, non-flammable

1.2. How to Apply Maxseal SUPER

Application by brush, broom or spray Mix just with water between 6 and 7 litres per each 25 kg bag, either manually or preferably by slow speed drill (400 – 600 rpm). Applications made at high temperature or sprayed, the water ratio can be increased slightly. For standard applications. Apply Drizoro Maxseal® SUPER with a fibre type brush or broom such as our MAXBRUSH or MAXBROOM.

Apply a thick layer to form a continuous and uniform coating; Do not spread as like paint. Apply 1st in one direction. Apply the second coat in a cross direction. Consumption is between 1 and 1,5 kg/ m² per coat, for a total consumption of about 2 – 2,5 kg/ m².

Waiting time between coats is from 6 – 8 hours minimum to 24 hours maximum.
It can be also sprayed by using shotcreting equipment.
For applications made by spraying which will be later subjected to water pressure. Drizoro recommends brooming over the material which has just been sprayed in order to ensure complete coverage of the surface.

Application by dusting

MAXSEAL® SUPER can also be dusted on the lean concrete and the steel reinforcements procedure will not only protect the reinforcement itself but will prevent the rising dampness into the foundation slab.
The lean concrete should be dampened until saturation. Then Drizoro Maxseal® SUPER is dusted using between 1,5 to 2,5 kg/ m².
Concrete for the foundation slab can be poured after one hour. Once Drizoro Maxseal® SUPER has hardened and adhered to the lean concrete, Use best endeavours not to damage the previous application.

Application by dusting and power trowel

For this case, the application is performed on the fresh concrete, after levelling, and has enough strength to be walked over, but still fresh enough to dampen the surface when troweled. 
The product is spread in powder form as supplied at a ratio of 1,5 to 2,5 kg/m², endeavouring to achieve complete and uniform coverage. Immediately after the surface is hosed down to prevent the superficial drying of the slab and to make the power troweling smoother.
The troweling will provide a monolithic waterproof layer, which can be slightly dampened during this operation to improve the penetration and to prevent an excessively quick-drying, which would prevent proper hydration of Drizoro Maxseal® SUPER.
Seal all one off areas columns, penetrating pipes, corners, concrete joints, and expansion joints prior to the general application.

2. DRIZORO MAXSEAL SUPER vs. BENTONITE CLAY MEMBRANE

This Technical Note aims to make a comparative study between the cement-based waterproofing system composed of Drizoro MAXSEAL SUPER and bentonite clay membranes (sheets/panels/textile mats). Generally, bentonite clay product-based systems show a lot of leaking problems. Leaks are are localized in areas such as joints, penetrating pipes and drains. Also, mechanical damage such as punching, cracks or tearing can be expected.
How to solve the above drawbacks. Cement-based waterproofing systems are a highly recommended option.
MAXSEAL® SUPER provides a watertight coating with high mechanical properties and chemical resistance regardless of whether an uneven surface is present or, UV radiation exposure or chemical attack is expected.
Unlike the use of a bentonite clay membrane, a continuous fully bonded material such as Drizoro MAXSEAL SUPER ensures an entirely watertight monolithic waterproofing application
