CFRD Modified Rubber Filled Material 1.Excellent flow sealing behavior 2.High slope stability 3.Cold applied --------------------------------------------------------------------------------------------------------Description

Filler is a kind of rubber sealing material and specially developed for top filling of the face

slab joint of CFRD , which can flow down and seal the open joint during impounding.

-----------------------------------------------------------------------------------------------------------------------------

Application

Filler is widely used in CFRD for its excellent flow sealing behavior, see the reference list.

According to the research result of CFRD (Shuibuya Dam height 233m), it can be used for

CFRD up to 250m high.

-----------------------------------------------------------------------------------------------------------------------------

Advantages

1. Excellent flow sealing ability, and its adaptable joint size will be up to 10cm width and

110cm width and 110cm depth.

2. No leakage occurs as it flows down into the joint

3. High slope stability without any sagging.

4. Cold applied with high workability.
