HERCULES Engineering (SEA) Sdn Bhd

INTRODUCTION

The HERCULES Rubber waterstops are divided into

two types which are dumbbell & center bulb

shaped. The waterstops are designed for joints in

structures such as bridges & etc. Hercules Rubber

Water stops are formed or extruded as a

continuous piece. Any required intersection can be

cold or hot vulcanized as site joining requirement.

MATERIAL SPECIFICATION

HERCULES waterstops are formed or extruded

from High quality Natural Rubber (NR) or

Neoprene to suit the projects requirements. It shall

comply to the following materials physical

properties specification;

INSTALLATION OF WATERSTOPS

HERCULES waterstops can be pre-vulcanized to the

required length and types of intersection prior to

installation at site. Anyway, hot & cold vulcanizing

can be performed at site if required.
