Back Stick Rubber Waterstop for Concrete Project
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.
BSRW-1: EB type back stick rubber waterstop with square bulb.
BSRW-2: EB type back stick rubber waterstop with bridge type bulb.
BSRW-3: EP type back stick rubber waterstop with four stems.
BSRW-4: EP type back stick rubber waterstop with four flat stems.
BSRW-5: EB type back stick rubber waterstop with six T type stems and square bulb.
BSRW-6: EB type back stick rubber waterstop with four stems.
BSRW-7: EP type back stick rubber waterstop with six stems.
BSRW-8: EP type back stick rubber waterstop with four stems.
Specification
