Description: Hydrocell XL is a cross linked, semi-rigid, closed cell polyethylene sheet material used for forming or filling expansion joints between adjacent in-situ or precast components. Hydrocell XL 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 water excluding structures. Uses: Hydrocell XL is a cross linked, non-absorbent, semi-rigid, cellular polyethylene joint filler used for forming expansion joints in concrete, brickwork and blockwork. The product provides excellent support to sealants subject to hydrostatic pressure and is particularly recommended for water retaining or water excluding structures. 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 compression recovery Non-extruding Low load transfer to joint edges Non-tainting and rot proof– Chemically resistant– Bitumen free– Natural bond breaker
