SRE Epoxy

Epoxy Waterproofing Method for Underground Parking Lots Reinforced with Super Microfibers 


waterproofing method using a surface preparation material with super microfibers and a urethane coating mixed with super microfibers in a weight ratio of 1000:1 to 1000:2. 


Patent certificate

[ Features ]

By incorporating super microfibers into urethane or epoxy, tensile strength, elongation, and hardness are significantly improved, effectively preventing bubble formation and pinhole defects during summer applications. This method eliminates the issue of re-cracking commonly found in urethane waterproofing materials. Additionally, compared to conventional KS-exposed urethane waterproofing, material costs remain similar, while construction costs are reduced.

Surface Preparation Material Using Super Microfibers 


[ Patent No. 10-1643520] 

Polyurea Waterproof Coating Method Using Surface Preparation Material with Super Microfibers

SRE epoxy technology is


An epoxy waterproofing method that is reinforced with super-micro fibers, It's similar to the old traditional method of adding straw to bricks to make them stronger.



Reduce construction costs by eliminating re-cracking and summer pinholes that occur with traditional epoxy waterproofing, and improved epoxy performance and quality, among other benefits, this technology is a winner of the Professional Construction Association Technology Award.

REQUIREMENTS FOR CONSTRUCTION

Requirements for Epoxy Applications in Underground Parking Garages


01.
You need a good concrete base.

  Grind the concrete surface if you notice any latency, bleeding, or loose concrete powder.

  If water is coming up from the floor, you'll need to address waterproofing.


02.
It should be constructed with a good quality epoxy.

  A good epoxy will ensure that you don't have a long construction period due to delayed curing or problems with the epoxy being knocked off by vehicle tires.

  The epoxy should not be easily abraded by the vehicle tires.

 The construction period should not be prolonged.

03.
Thicker or non-slip treatments should be used where it matters.

  For heavily traveled roads, make the lining 1 mm thicker.

  Apply 2 thin coats to the parking surface.

  Intersections and main entrances are non-slip.

Latency phenomena

A thin layer that develops on the surface of concrete. When concrete is poured, it fails to mix homogeneously, causing the materials to separate and the water to settle to the top, sand to the bottom, and gravel to the bottom due to differences in specific gravity, causing impurities to appear on the surface after the water evaporates.

Bleeding

The leaching of moisture from the surface of less-hardened concrete as the material separates. While concrete is curing, some of the mix water separates and rises to the top of the concrete.

Defects in underground parking lot epoxy coatings
 are caused by low-quality epoxy and poor concrete substrate. 



01.
Poor and delayed epoxy cure under low temperature conditions (10℃ to 15℃ or lower)

※ Poor and delayed epoxy cure, similar to thinner overdilution

If the defect reappears, the resident's vehicle will be prohibited from parking in the parking lot for a longer period of time, which will cause complaints. If the curing is not complete or delayed, the phenomenon will appear as shown in the photo above.

02.
Tire marks falling off due to poor curing in the fall of construction

The epoxy did not cure after application, causing the tire marks to fall off because the epoxy and the concrete floor surface are not bonded.

03.
Regular epoxy has low abrasion resistance and will wear out quickly.

Regular epoxies have lower performance, such as abrasion resistance and compressive strength, which means they are less likely to withstand common external pressures.

04.
The construction period will end up being longer.

Poor curing and delays that occur after epoxy installation can cause major inconvenience and frustration for users, as they need more time to repair the defects, which can extend the period of use of the underground parking lot.

SUPER MICRO FIBER REINFORCED EPOXY

Patent No. 10-1643519

Patent No. 10-1643520

Super microfiber blends

for even more performance


SRE epoxy is a blend of supermicro fibers that minimizes summer pinhole formation, and the microscopic fibers inhibit pinholes. The enhanced performance also improves abrasion resistance and durability, and is more resistant to external pressures, keeping your underground parking garage floor healthier and longer.

SRE EPOXY SUPER MICRO FIBER


Patented, groundbreaking, practical epoxy reinforcement technology that blends small, thin, and fine fibers to enhance the performance of epoxy


The principle of adding straw when making ocher bricks


SRE epoxy follows the same principle used in the past when making bricks stronger and more durable by adding straw in the traditional method.  


To create a stronger and higher-performing epoxy, 

we have incorporated super micro fibers.

How different is a good epoxy from a great epoxy?

Low-cost (generic) epoxy


10-year life (70 mg abrasion resistance)

Abrasion resistance: How well it resists abrasion

(amount of epoxy powder released by rubbing)

Superior epoxy


12.3 years lifetime (55 mg wear resistance)

Abrasion resistance: How well it resists abrasion

(the amount of epoxy powder that comes off when rubbed)

Regular epoxy 

has fewer topical ingredients.

More hardener ingredients are cheaper and lower quality,

leading to lower quality construction.

A superior epoxy contains a higher ratio of main components and is reinforced with super micro fibers for high-quality, enhanced performance. 

More thematic components means better abrasion resistance.
