Back Stick Rubber Waterstop

Back stick rubber waterstop is made from natural rubber or synthetic rubber, adding various additives and fillers, through the process of plasticizing, mixing, pressing, forming. One side of product is flat, the other side has stems or bulb. It has many species, such as bridge type, mountain type, P type, U type, Z type, T type, H type, E type, Q type, etc. It also can be divided into EB type and EP type. The product utilizes rubber's high elasticity and can arise elastic deformation under various load, thereby achieving the effect of preventing water seepage and leakage, absorb shock. It mainly used in construction joints, settlement joints and movement joints of foundation engineering, underground facilities, tunnel, culvert, aqueduct, dam, etc, to ensure the life of project.
Specification
Material: rubber.
Species: EP type (without center bulb), EB type (with center bulb).
Length, width and thickness can be customized.
Due to stem has many species, customers should provide drawing.
