Description
Estop Hydrocell is a cross linked, semi-rigid, closed cell polyethylene sheet material used for forming or filling expansion joints between adjacent in-situ and precast components. Estop Hydrocell provides excellent support backing to elastomeric sealants and is especially recommended for use in expansion joints in brickwork and in the construction of water retaining and excluding structures.
Estop Hydrocell has been tested by in accordance to ASTM D3575, on the Recovery, Compressive Strength and Water Absorption, and complied with the specification in this data sheet.
Uses
Estop Hydrocell is a particularly recommended for water retaining or excluding structure.
- Potable water reservoirs
- Culverts and canals
- Sewage tanks
- Roadways and hardstandings
- Retaining walls
- Basement structures and subways
- Runways, taxiways and aprons
Advantages
- Cross linked to resist lateral and hydrostatic pressure
- High density support of sealant to prevent adhesion failure
- Non-absorbent closed cell structure
- High recovery under compression
- Non-extruding
- Low load transfer to joint edges
- Non-tainting and rot proof
- Chemically resistant
- Bitumen free
- Natural bond breaker
Standards Compliance
- ASTM D3575
- ISO 845

Application Instructions
Joint Sealing Slots
When forming expansion joints with Estop Hydrocell in in-situ concrete, joint sealing slots can be readily formed in the following manner.
Before installing, simply cut off a strip to the required depth. Pin the strip back by using 50 mm nails at approximately 100 mm intervals. Then install the filler flush with the finished surface.
Prior to sealing, the top strip can then be pulled easily from the joint to provide an uncontaminated sealing slot ready for preparation and sealing.
As elastomeric sealants will not bond to Estop Hydrocell the additional need for bond breaker strips is eliminated.
Limitations
Estop Hydrocell should not be used when the operational temperature is continuously outside the range of -70°C to 100°C.
Estimating
Estop Hydrocell is supplied in the following sheet sizes and can be easily cut to the required size with Stanley knife or saw
10 mm x 1200 mm x 1850 mm
15 mm x 1200 mm x 1850 mm
20 mm x 1200 mm x 1850 mm
