ActiFill Bentonite Granules 25kg
ActiFill Bentonite Granules is a treated granular sodium bentonite used primarily as a detailing accessory product within waterproofing systems. ActiFill can be used dry or pre-hydrated and in confinement will form a dense waterproof ‘paste’ to act as detailing compound. When applied with ActiTex the sodium bentonite will combine to form a seamless homogeneous water system.
Free swell rating of ActiFill is 2g sifted into deionised water to swell and occupy a minimum volume of 16cc
TYPICAL USES
- Fill Material – to fill cavities or voids in the substrate prior to installing waterproofing membrane/system.
- Fillet Material – when hydrated to form a ‘paste’ around penetrations and horizontal/vertical junctions
- Buried Roof Layer – 3mm bed of ActiFill is applied to the top of tunnels or buried roof structures (minimum 1mtr below fully compacted well graded soil) prior to application of ActiTex
APPLICATION
ActiFill is a granular material General – All surfaces to receive ActiFill should be dry, free of dirt, grease, rust, oil, curing agents or other contaminants. To place as granules cut a corner of the bag for directional control of product placement. To apply as a paste – Pour clean water into the bag covering the visible surface. Allow the water to soak into the granules for a few seconds, a crust will form which can be removed and moulded for application as fillets, etc. If there is excess water on the surface of the crust break through to expose dry granules. This process should allow full use of a bag of ActiFill. Apply ActiFill prior to installation of waterproofing membrane, unless in accordance with specific approved detail.
LIMITATIONS
- ActiFill is not designed to function as an expansion joint sealant.
- ActiFill is not an adhesive.
- ActiFill should not be left exposed for prolonged period prior to concrete or backfill placement.
- Use ActiFill in applications with adequate confinement only. Backfilled soils should be of fully compactable well graded materials.
