Application Instructions

Width of Estopper Hypatite

Estopper Hypatite is supplied in standard widths 200 mm. It is  for use in buried joints (Expansion, construction and contraction joint) in trafficked surfaces and bridge decks.

Surface Preparation

Substrate to receive Estopper Hypatite must be sound, dry, frost and dust free. New concrete must be fully cured and free from curing compound. The concrete surface ideally should be wood float finished and free from irregularities.

Any honeycombing must be repaired using suitable Estop patching mortar

Preparation of the membrane

Measure and cut the length of Estopper Hypatite and ensure  that it is dry and clean from any oil, grease etc.

Mixing and application of the adhesive Estobond Hypa adhesive is supplied in two parts.

Mix the whole pack thoroughly using a slow speed drill until uniform colour is achieved.

Apply the mixed Estobond Hypa on each side of the joint to a thickness of approximately 3mm. Place Estopper Hypatite on top of Estobond Hypa. Using a hard roller, force the Estopper Hypatite down into the Estobond Hypa until the material come out from the punched holes of Estopper Hypatite.

Apply an additional 3mm layer of Estobond Hypa to hold the Estopper Hypatite. See Illustration 1 below. Estobond Hypa shall be applied at least 5mm wide, as per illustration below.

The membrane should be applied not more than 20 minutes after adhesive application and allowed to cure to ensure that the adhesive is not disturbed prior to laying of asphalt or other surfacing.

Jointing the Estopper Hypatite membrane Estopper Hypatite can be jointed by Estobond Hypa.
