What tests have been preformed to verify how well PaviX works on concrete?
PaviX has undergone a battery of ASTM specified tests by an independent testing laboratory familiar with concrete testing. The current ASTM tests PaviX has been analyzed for are the following: Freeze- Thaw test C-666, Scaling test C-672, Product Penetration C-856, Abrasion Resistance C-944, Water Soluble Chloride C-1218, Pull-Off Strength test D-4541 and Water Vapor Transmission E-96.

How deep does the PaviX crystalline formation penetrate the concrete?
The reactions that initially take place at the concrete surface is a liquid application that immediately penetrates into the capillary pores of the concrete surface. Over a short period of time depending on humidity levels the liquid PaviX turns into a gel which in –turn forms hygroscopic and hydrophilic crystals. PaviX will search out moisture to the bottom of the capillary tube regardless how long it is in length.

How long does PaviX last?
PaviX product application is permanent. Once placed, the crystals remain active indefinitely. Its unique crystalline growth structure will not deteriorate.

How resistant is PaviX to chemicals?
Based on independent testing PaviX is not affected by a wide range of chemicals including mild acids, solvents, chlorides and caustic materials. It is resistant to oils, fuels and prevents dusting.

Is PaviX affected by temperature, humidity, ultraviolet and oxygen levels?
Humidity, ultraviolet and the oxygen level (oxidation) have no effect on a PaviX. As humidity increases, the crystals actually swell in the capillaries to block moisture from entering the capillary.

Does PaviX protect reinforcing steel?
Yes. By preventing the intrusion of chemicals, salt water, sewage and other harmful materials, PaviX protects concrete and reinforcing steel from deterioration and oxidation. If corrosion has already present, it will slow the process by not allowing moisture to enter the capillary tube.

Does PaviX protect concrete against freeze/thaw damage?
Yes. By blocking the intrusion of water into concrete, PaviX protects the concrete from the damaging effect of repeated freeze/thaw cycles.

Is PaviX toxic?
No. PaviX contains no volatile organic carriers (VOC) is completely safe to the environment.

Can PaviX be applied against hydrostatic pressure?
Yes. Because PaviX is not dependent upon adhesion to the concrete surface and instead becomes an integral part of the concrete mass through crystallization, it is capable of resisting hydrostatic pressure from either side (positive or negative) of the concrete.

Can PaviX be applied while the concrete is wet?
Yes and No. Best results are obtained when the concrete is dry or slightly moist but not wet. PaviX being water based carries the crystalline growth deep into the concrete. PaviX, once applied will not be affected if rain were to fall shortly after application. PaviX starts working immediately after application.

Is PaviX used to waterproof cracks, joints and other defects in concrete?
Yes. PaviX has a specific repair system that utilizes its unique crystalline waterproofing technology to stop water flow through up to 1/16 cracks. In the case of expansion joints or chronic moving cracks, a flexible sealant is recommended.

Is PaviX suitable for use on surfaces other than concrete?
PaviX is totally compatible with the chemistry of concrete, whether poured-in-place, pre-cast or concrete block. PaviX may also be used on mortar, plaster, stucco, terrazzo, exposed aggregate and any sand aggregate cement combination.

What is the appearance of a PaviX coating?
PaviX is a colorless, transparent liquid; initially the concrete will appear darker for several days until the material has dried the concrete. When moisture is present, PaviX treated surfaces will not change in color because no moisture can penetrate into the concrete.

Can paint and other finishing materials be applied over a PaviX coating?
Yes. Paint, cement purge coats, plaster and stucco can be applied or installed over concrete protected with PaviX. For detailed instructions, refer to PaviX "Specification and Application Information".

What are some typical PaviX applications?
PaviX can be applied to any concrete surface. Applications include Bridge decks, Airport Runways, Reservoirs, Tunnels, Parking Structures, Sidewalks, Sewage and Water Treatment Tanks, Secondary Containment Structures, Underground Vaults, Foundations, Roof Decks, and Below Grade
Construction.

How is PaviX different from other products?
The dual PaviX crystalline formation (hygroscopic & hydrophilic) for concrete waterproofing is substantially different from traditional barrier products (membranes, cementitious coatings):
1. PaviX creates a crystalline structure deep within the pores and capillary tracts of the concrete mass to prevent the penetration of water and aggressive chemicals and also form a barrier at the surface of the concrete.
2. PaviX it is resistant to hydrostatic pressure.
3. PaviX will seal hairline cracks up to 1/16 inch.
4. PaviX will not deteriorate after years of intense service.
5. PaviX is permanent and crystals activates whenever moisture is present.

What are the application advantages of using PaviX?
The crystalline nature of the PaviX waterproofing system provides many application advantages:
1. PaviX is a single component dual crystalline hygroscopic & hydrophilic product.
2. PaviX is fluid applied water based material.
3. Application equipment from brooms, squeegee, hudson hand sprayers or 250-2500 gallon sprayer units are readily available.
4. PaviX requires no special protection during backfilling or during placement of steel, wire mesh or other materials.
5. PaviX can be applied on either side of a concrete surface – the negative or the positive (water pressure) side.
6. PaviX forms a monolithic coverage that can be added to at any time.
7. PaviX is less costly to apply than most other methods.

What is the recommended application rate for PaviX?
Typically a coverage rate of between 150 – 200 square feet per gallon will provide ample coverage. Consultation with the manufacturer’s technical department or your local PaviX representative for assistance in determining the appropriate dosage rate based on specific requirements and conditions of your project.
