Root puncture resistant waterproofing membrane is mainly used for the plant root puncture resistant layer of roofs and underground building roofs that require greening, ensuring that the plant roots do not damage the structure below this level and have waterproof function.

Root puncture resistant waterproofing membranes can be divided into asphalt based root puncture resistant waterproofing membranes and polymer based root puncture resistant waterproofing membranes according to their materials.

1、 Asphalt based SBS root puncture resistant waterproofing membrane can be divided into:

1. Copper tire based SBS waterproofing membrane

2. Chemical barrier SBS waterproofing membrane

What are the characteristics of asphalt based root puncture resistant waterproofing membrane?

(1) It has dual functions of waterproofing and preventing plant roots from penetrating, and can withstand plant root piercing, maintaining its waterproof function for a long time;

(2) Both prevent root puncture and do not affect normal plant growth;

(3) It can form a high-strength waterproof layer, with strong resistance to water pressure, and is resistant to puncture, cracking, tearing, and fatigue;

(4) High tensile strength, thick asphalt coating layer, strong adaptability to base shrinkage deformation and cracking;

(5) Excellent high and low temperature resistance, suitable for both hot and cold regions;

(6) Good corrosion resistance, mold resistance, and weather resistance;

(7) Hot melt method construction is convenient and the hot joints are reliable and durable.

2、 Polymer based root puncture resistant waterproofing membranes can be divided into:

1. PVC root puncture resistant waterproofing membrane

2. TPO Root Piercing Waterproof Membrane

3. Polypropylene root puncture resistant waterproofing membrane

What are the characteristics of polymer based root puncture resistant waterproofing membranes?

(1) The product has a dense texture, low water vapor permeability coefficient, and excellent waterproof performance;

(2) High mechanical strength and strong puncture resistance;

(3) Good chemical resistance, aging resistance, and corrosion resistance;

(4) Non toxic, long service life;

(5) It has the function of preventing plant root penetration and can withstand plant root puncture. Prevent root puncture without affecting normal plant growth;

(6) Good flexibility, easy to bend, can be folded freely, and easy to operate;
