Volclay Accessories

As well as supplying the Volclay® Waterproofing System core products, Allco Waterproofing Solutions is also able to supply accessory products for a complete single-source waterproofing system.

Volclay Bentoseal®

Volclay Bentoseal is trowel-grade, sodium bentonite/butyl rubber based sealant designed for a variety of surface preparation and waterproof detailing work

Trowel-Grade Sodium Bentonite Sealant

Volclay Bentoseal® is trowel-grade, sodium bentonite/butyl rubber based sealant designed for a variety of surface preparation and waterproof detailing work with Swelltite® and Voltex® waterproofing membranes. Being bentonite based, Bentoseal® swells upon contact with water to seal against water intrusion. With the consistency of thick grease, Bentoseal® is easy to apply to most substrate materials.

Applications

Bentoseal® is a below-grade waterproofing accessory product designed for the following uses:

  • Fillet material at horizontal and vertical inside corners

  • Flashing material around drains, mechanical and electrical penetrations, curbs and parapets

  • Sealing material at waterproofing terminations

  • Repair material for small concrete substrate surface defects prior to waterproofing membrane installation

  • Trowel-grade waterproofing for extremely irregular substrate surfaces

Bentoseal® is formulated for use on structural concrete, masonry, wood and most metal surfaces. Do not use Bentoseal® on extruded polystyrene (EPS) concrete forming systems. Use in applications with proper confinement only. Backfill soils should be compacted to a 85% Modified Proctor density (For more information with regards to backfill, please refer to Backfill Tech Ref 205). Bentoseal® is not an expansion joint sealant.

Volclay Cetcoat®

Cement-based Crystalline Waterproofing System

CETCOAT 1P is a unique flexible one component waterproof membrane that is suitable for a wide range of positive & negative waterproofing applications. Based on an advanced cross linking polymer technology, CETCOAT 1P is a standalone flexible polymer cementitous membrane that does not require the addition of any liquid additive, requiring only water added to powder to form a high quality liquid membrane slurry system. Ideally suited over concrete, masonry and mineral substrates, the cured film provides a water tight membrane that is permeable to vapor diffusion and offers excellent resistance to frost and ageing, as well as outstanding adhesion properties.

Termination Detail

For use on the above/below ground transition, especially in garden areas & stair transitions, refer to the termination details provided by Allco Waterproofing Solutions.

Applications

Cetcoat® is recommended for use on below-grade walls and slabs on either the negative- or positive-side where protection from water intrusion is required. Cetcoat® may be used to waterproof foundations, basements, tunnels, water reservoirs, sewage plants, water ranks, swimming pools and manholes. A typical application of Cetcoat® serves to provide a waterproof barrier up to 30 metres of hydrostatic pressure.

  • Packaged in convenient kits to cover 9.5 metres

  • Durable yet flexible

  • No priming required

  • Negative- or positive-side applications

  • Breathable to prevent vapour build-up

  • Brush, spray or broadcast applications

Requires no curing

Volclay Cetplug®

Hydraulic Patching Compound

The accessory product Cetplug® completes the Cetcoat® system. This unique waterproofing system can be used to provide complete protection to concrete and masonry.

Cetplug® is a quick-setting hydraulic cement-based patching compound designed to stop active seepage through concrete and masonry. It will not shrink, rust or spall in moist conditions. When mixed to a putty consistency and forced into active leaks, Cetplug® stops waterflow immediately.

Applications

Use Cetplug® to fill voids, cracks or honeycomb in cast-in-place or precast concrete when active leaks are present. Typical applications include foundations, basements, tunnels, water reservoirs, sewage plants, water tanks, planter boxes and manholes.

  • Rapidly stops active leaks

  • Initial set in 1 to 3 minutes

Non-shrink, non-metallic

M-2000 Liquid Flashing

Trowel-Grade Single Component Urethane Mastic for a Variety of Waterproofing Applications

Trowel-Grade Single Component Urethane Mastic

M-2000 Liquid Flashing is trowel-grade, cold-applied, single component urethane mastic designed for a variety of uses with Environsheet® rubberised asphalt waterproofing membranes and Volclay Swelltite® bentonite waterproofing membranes. M-2000 Liquid Flashing moisture cures to form a continuous, seamless, positively bonded, elastomeric material. M-2000 Liquid Flashing contains no coal tar and conforms to the performance requirements of ASTM C 836-89a.

Applications

M-2000 Liquid Flashing is an accessory waterproofing product designed for the following uses:

  • Fillet material at horizontal and vertical inside corners

  • Flashing material around drains, mechanical and electrical penetrations, curbs and parapets

  • Sealing material at membrane terminations

  • Repair material for small concrete surface defects

  • Flashing material at inside corner

M-2000 Liquid Flashing is formulated for use on structural concrete, masonry, wood and most metal surfaces. Do no use M-2000 on extruded polystyrene (EPS) concrete forming systems.

Volclay® Seamtape

Multi-Purpose Joint Tape

Multi-Purpose Joint Tape for Waterproofing Membrane Overlap Seams

Volclay® Seamtape is a 50 mm wide by 0.64 mm thick butyl rubber tape used to seal Volclay Swelltite® Waterproofing Membrane overlap seams. Volclay® Seamtape consists of 0.50 mm of black adhesive butyl compound integrally bonded to a 0.14 mm thick high density polyethylene film.

The inherent adhesive and waterproofing properties of the tape effectively seals the liner face of Swelltite® at the membrane overlaps. Seamtape provides good chemical resistance and excellent moisture barrier properties. Its outstanding conformability allows the tape to be easily installed on irregular surface conditions.

Applications

Volclay® Seamtape is used for sealing the overlap seams of Volclay Swelltite® for both vertical and horizontal applications. It protects the seams of installed Swelltite® membrane against debris intrusion during backfill and damage from rain prior to backfilling. Additionally, Seamtape decreases the vapour or gas permeability of the seam. Seamtape may also be used to repair small tears or punctures in Swelltite’s heavy geomembrane liner.

Volclay TB-Boot™

Flexible EPDM Tie-Back Head Cover

Volclay TB-Boot is a flexible, preformed EPDM boot used primarily to detail tie-back heads on soldier pile and lagging shoring walls

Volclay TB-Boot™ is a flexible, preformed EPDM boot used primarily to detail tie-back heads on soldier pile and lagging shoring walls. The flexible cone shape can be adjusted to a shallow depth for short tie-back heads or installed to its full height coverage when required.

Typical Applications

Volclay TB-Boot™ is designed for typical tie-back heads ranging up to 150mm (6″) in diameter. For covering larger tie-back heads, Allco recommends the use of field fabricated metal sheet boxes (minimum 25 gauge galvanised steel) filled with a 50/50 mix of Bentoseal® and waterstoppage (premium granular sodium bentonite). Contact Allco Waterproofing Solutions for additional application recommendations.

Volclay Waterstoppage®

Granular Sodium Bentonite

Waterstoppage - Waterproofing Granular Sodium Bentonite

Volclay Waterstoppage® is chemically treated, granular sodium bentonite used as a detailing accessory product for Volclay® Waterproofing Systems. When wetted, Waterstoppage® forms into a dense, low permeable material that combines with the sodium bentonite in the Volclay® System products to form a seamless waterproofing membrane.

Mineralogical composition of Waterstoppage® is a minimum 90% Montmorillonite with a maximum 10% native sediments and unaltered volcanic ash. Typical sieve analysis is 90% through a 20 mesh sieve and 10% through a 200 mesh sieve. Free swell rating of Waterstoppage® is: two grams sifted into deionised water swells to occupy a minimum volume of 16cc.

Applications

Volclay Waterstoppage® is used to fill cavities and voids in the substrate prior to installing the main bentonite waterproofing course. It is also used to seal around slab penetrations to form a continuous waterproofing system. A fillet of Waterstoppage® can be poured at the footing/wall junction to provide additional waterproofing protection. A 3 mm (1/8″) thick layer of Waterstoppage® is also applied to the top of tunnels and earth-covered roofs prior to the main Volclay® waterproofing material course.

Waterstoppage® is not an expansion joint sealant.
