China Shenzhen Joaboa Technology Co., Ltd Company Zero Defect Waterproof Service System

Brief Introduction of Zero Defect Waterproof System

Zero Defect System was officially launched in 2014, which is the 1st comprehensive waterproof service system in China Building Waterproofing Industry, covering design, material, construction, supervision, guarantee and other aspects involved. The system structure mainly adopts Bondsure® Self-adhesive Waterproof Membranes + NRB Non-curing Rubber Bitumen Waterproof Coating togehter, to form a Skin Type waterproof system. Zero Defect System provides the first waterproof engineering quality assurance insurance in the industry.

Project Insurance Mechanism of Zero Defect Waterproof Service System

The first point regarding Zero Defect Waterproofing System is Joaboa Tech is responsible for the result. If any leakage issues happened in Zero Defect System Project, Joaboa Tech will bear the responsibility, no matter whether it's problem from the designer, main contractor, developer or any other parties: firstly, Joaboa Tech will arrange our construction teams to repair until there’s no leakage; in the meantime, according to our commitment, "ONCE LEAKAGE, FULL COMPENSATION", the compensation will be given according to the size of construction area.

Design Idea of Zero Defect Waterproof System

ZERO DEFECT SYSTEM is based on Joaboa Tech's SKIN TYPE waterproof theory, which can greatly enhance the reliability of the waterproof project by eliminating the fluid-channel between the waterproof layer and the substrate. Even if there are damages or defects in the waterproof layer, they won't destroy the whole waterproof system. In order to make this design idea come into reality, Joaboa Tech chose "waterproof membranes & waterproof coatings" as the complete waterproof materials.

Material Combination of Bondsure Membranes & NRB Coating

Zero Defect Waterproof System mainly adopts Bondsure® Self-adhesive Waterproof Membranes + NRB Non-curing Rubber Bitumen Waterproof Coating togehter, to form a Skin Type waterproof system. Bondsure® is a famous trademark in China, belonged to Joaboa Tech Group, and it also represents Chinese Self-adhesive Bituminous Waterproofing Membranes in Chinese mainland. The sales of Joaboa Tech's Self-adhesive Waterproofing Membranes has ranked TOP in China for many years. NRB Non-curing Coating is Joaboa Tech's another contribution to the waterproofing industry.

Introduction of Bondsure® Self-adhesive Waterproofing Series

With excellent characteristics of tensile strength and fatigue resistance ability, Joaboa Tech Bondsure® Self-adhesive Bituminous Waterproofing Series have been regarded as the representative of self-adhesive membranes in China for more than 20 years. Bondsure® Membrane Series consist of Single-sided Self-adhesive Membranes(like PET, CLF, S-CLF NS Type), Double-sided Self-adhesive For Zero Defect System, Bondsure® Single-sided/Double-sided Self-adhesive/BAC Root-resistant Membranes will be chosen.

Introduction of NRB Non-curing Rubber Bitumen Waterproof Coating

NRB Coating is a made of rubber, asphalt and additives, which always remains viscous during application. The product will be heated into a flow state on site, and scraped or sprayed on the base to form a waterproof layer with strong adhesive force, excellent creep property, self-healing function and aging resistance. It is both a waterproof layer as well as a bonding layer. According to physical properties, NRB Coating are divided into two types: L-type (plane), V-type (facade).

Comprehensive Introduction

Zero Defect Waterproof System

Zero Defect Waterproof System was officially launched in 2014, which is the 1st comprehensive waterproof service system in China Building Waterproofing Industry, covering design, material, construction, supervision, guarantee and other aspects involved.

The system structure mainly adopts Bondsure® Self-adhesive Waterproof Membranes + NRB Non-curing Rubber Bitumen Waterproof Coating togehter, to form a Skin Type waterproof system. Zero Defect System provides the first waterproof engineering quality assurance insurance in the industry.

It promises to be responsible for the result of "no leakage". Until June 30th, 2021, it has been successfully applied in over 21,260,000㎡ of waterproof projects, equivalent of 2,978 international standard football fields, and no compensation asked for.

Till now, Joaboa Tech is still the ONLY 1 in Chinese mainland who can provide project insurance for the waterproof projects.

※ Introduction of Bondsure Self-adhesive Waterproofing Membrane Series

Bondsure® Membrane Series consist of Single-sided Self-adhesive Membranes(like PET, CLF, S-CLF NS Type), Double-sided Self-adhesive Membranes(like BAC, BAC-P, S-CLF ND Type), Pre-applied Membrane (S-CLF YC Type, MAC), Torch-applied Membranes(SBS, APP), Synthetic Membranes (PVC, TPO, Self-adhesive TPO) and Root-resistant Membranes(Root-resistant BAC/PVC/SBS/TPO), etc.

For Zero Defect System, Bondsure® Single-sided Type, Double-sided Self-adhesive Type, BAC Root-resistant Self-adhesive Type will be chosen.

※ Introduction of NRB Non-curing Rubber Bitumen Waterproofing Coating

NRB Rubber Bitumen Waterproofing Coating is a kind of sticky and pasty waterproofing coating inapplication condition, which is made up of rubber, bitumen and other auxiliaries.

Before application, it will be heated to flowing type and form a perfect waterproofing layer with strong adhesion, creep property and self-healing performance.

It can be used as a separate waterproofing layer, but can also be applied together with waterproofing membranes to form into composite system.

Reference dosage: 2.5kg/2mm/m2 Packages: 20kg /pail

※ System Features

1. Strong resistance to external forces, excellent tensile and fatigue resistance performance.

2. After application, there won't be fluid-channeling between waterproofing membrane layer and waterproofing coating layer. Even if there are any small damages, the water will be strictly limited in a small scale, it will not flow here and there.

3. As NRB Non Curable Rubber Bitumen Waterproofing Coating will be heated into flow type as bonding layer before applied with

waterproofing membranes, it will be possible and rather convenient for the construction in cold winter.

4. Waterproofing Membranes are designed and produced as double-sided self-adhesive type, which will greatly enhance the

reliability and safety of the waterproofing system, as well as convenient for the application.

※ Scope of Application

Zero Defect Waterproof System is applicable to waterproof and anti-seepage projects in basement, roof, and other parts of industrial and civil buildings.

※ Construction Methods

Zero Defect Waterproof System can use construction method as below: Hot Application.

Introduction of Hot Application

HOT APPLICATION is composite of rubber asphalt waterproof coating and self-adhesive membrane which is closely bonded with the base layer to form a "skin-type" waterproof system. It is an organic whole with complementary advantages, which can adapt to the deformation and self-healing performance of the base, effectively prevent water channeling and reduce leakage hazards.

Substrate Requirements

1) The firmness and strength of the base layer should meet the design requirements.

2) The surface of the base layer should be clean and smooth, and there should be no quality defects such as powdering, sanding, peeling, voids and pits.

3) Remove sundries, greasy dirt, sand, etc. on the surface of the base layer, and the cleaning work must be carried out at any time during the construction.

4) If there is clear water on the base layer, it needs to be cleaned before construction. If the base surface is relatively damp, it needs to be dried with a blower.

※ Storage and Transport

1. Different types or specifications of products should be separated, not mixed.

2. Keep it dry and ventilated, protected from the sun or rain.

3. Storage temperature should not be higher than 45 ℃. Pile up the membranes flatwise whose stockpile height should not exceed five layers.

4. Prevent tilt or side pressure during transportation, and cover with felt if necessary.

5. Storage time is at least one year from manufacture date if the product is under normal storage condition.
