High Specification Rubber Dams

The AquaPro Rubber Bladder is made up of EPDM rubber which resists weathering, ozone, ultra violet light and the effects of extreme temperatures. The AquaPro Rubber Bladder incorporates a reinforcement Polyester fabric which gives the bladder its high tensile strength and has a significant advantage in terms of its ‘memory’ of shape during long periods of deflation, as well as being 100% watertight in comparison to the absorbent Nylon fabrics traditionally used. The bladder is available in a range of thicknesses, used in accordance with the conditions at site.

The Anchoring & Clamping System is simple, easy to install and provides an airtight/watertight seal. Depending on factors such as the overflow and the down stream water level, a single or a double anchor line is used to fix the rubber bladder to the foundation. The embedded plates and anchor bolts are normally cast into new concrete foundations, however, they can also be effectively fixed with resin on existing foundations.

In case of air-filled rubber dams, it is important that the bladder lies flat when fully deflated. A unique spacer system channels the evacuating air to an air-exhaust outlet, making sure no air pockets are formed thus ensuring a flat profile when fully deflated.

To provide complete protection against abrasion and impact by water borne loads and preventing debris from lodging beneath the bladder, a specially designed Anti-abrasion Protection Layer is attached to the concrete foundation on the downstream side of the Rubber Dam.
It guarantees zero friction between the bladder and anti abrasion protection layer when in contact with water.
