WATERPROOFING ACCESSORIES

	
I. Base treatment and Bonding Materials

1. Base treatment agent

It is used to enhance the adhesion between the base layer and the waterproof layer, such as cold base oil (suitable for asphalt-based rolls), polymer-modified asphalt treatment agents (such as chloroprene rubber adhesives), etc. The appropriate treatment agent should be selected based on the type of coil material.

2. Adhesive

Cold adhesives: such as polymer-modified asphalt adhesives, suitable for cold construction methods, reducing the risk of open flames.

Hot melt adhesive: It is used for hot-melt construction of rolls (such as SBS modified asphalt rolls), which need to be bonded after being heated by a blowtorch.

Self-adhesive layer: Some rolls come with a high-performance self-adhesive layer. When wet-laid, the bonding is achieved through physical mortise and tenon and chemical cross-linking.

Ii. Sealing and Reinforcing Materials

Sealing tape/paste

It is used for sealing joints such as the lap edges of rolls and the roots of pipes to prevent water leakage. For example, polyurethane sealant and butyl tape.

2. Enhance the mesh fabric/fiber layer

The fiber-reinforced layer on the surface of the polymer sheet material can enhance tensile strength and, when used in combination with coatings, form a stable waterproof layer.

3. ** Waterproof gasket and waterstop **

Rubber waterstop: Used in expansion joints and settlement joints, it ADAPTS to structural deformation and blocks water.

Waterproof gasket: Installed at connection points (such as bolts, pipe joints) to prevent water seepage.

III. Construction Auxiliary Tools

1.Roller and scraper

It is used to eliminate air bubbles during the laying of rolls and ensure complete adhesion to the base layer.

2. Blowtorch/hot air gun

An essential tool for hot-melt construction, used for heating the asphalt layer at the bottom of the roll material.

3. Cutting tools

For instance, paper cutters are used for precise cutting of rolls, reducing the number of seams (especially at complex areas such as pipe roots and corners).

4. Special Node Processing Accessories

1. Prefabricated components for positive and negative corners

Pre-formed arc-shaped fittings are used to handle the right angles at the junctions of the wall and the floor, reducing the cracking of the rolls caused by stress concentration.

2.  Pipe Waterproofing Kit 

It includes flexible waterproof sleeves, pipe root sealing rings, etc., and is suitable for waterproof reinforcement of wall-penetrating pipes, floor drains and other parts.

3. Flooding strip

It is installed at the junction of the roof and the wall to guide the direction of water flow and prevent water from seeping in.

V. Supporting Materials for Composite Waterproofing Systems

1. Non-curing rubber asphalt coating

When used in combination with rolls, it forms a self-healing waterproof layer that can adapt to the deformation of the base layer.

2. Polyurethane/Acrylic coatings

- Apply to the surface of the roll material to enhance the overall waterproof performance.

Vi. Inspection and Maintenance of Accessories

1. Water storage test equipment

It is used to test the airtightness of the waterproof layer during the acceptance stage.

2. "Repair materials

When there is local damage, it should be repaired with rolls or coatings of the same material, and adhesive and sealing materials should be used in combination.

Application Scenario Example - ** Building roof ** : It needs to be matched with waterstop, flood strips and weather-resistant rolls (such as SBS modified asphalt rolls).

- ** Basement/Tunnel ** : Self-adhesive rolls + waterstop + cement-based permeable crystalline coatings are preferred to adapt to high-humidity environments and structural deformations.

- ** Pipe/Node Waterproofing ** : Rely on sealing tape, sleeves and reinforcing mesh fabric to prevent joint leakage.

Purchase Suggestions

Compatibility  : Accessories must be compatible with the main materials (rolls/coatings), for example, self-adhesive rolls need to be matched with wet-laid adhesive powder.

Weather resistance  : For outdoor projects, materials that are resistant to ultraviolet rays and aging (such as aluminum-coated membrane rolls) are selected.

Environmental Protection and Safety : Prioritize the use of low-VOC adhesives and avoid the use of solvent-based materials in confined Spaces.
