Uses
Used in conjunction with a fully bonded sheet or liquid applied waterproofing membrane, it provides a secondary line of waterproofing defense against water ingress through static construction joints, cold joints and pipe penetrations in freshwater environments.
Typical applications include:
- Below ground construction joints to retaining walls and footings, lift pits, basement slabs, basement walls, basement slab-to-wall joints, pile-to-slab, pile-to-pile cap and pile-to-capping beam connections
- Pipe and conduit penetrations through structural concrete
- Above ground slab-to-slab and slab-to-wall construction joints to podiums, roof tops and terraces
- Construction joints in civil applications such as road and rail tunnels, water storage tanks and reservoirs

General Guidance:
| PRODUCT |
MAXIMUM COVERAGE PER LINEAL METRE |
| WATER-BAR™ XR-2010 |
1 lineal metre / lineal metre of joint + 100mm laps between rolls |
| SWELLSEAL® Mastic WA |
10mm bead to rough concrete – 6 lineal metres / 600ml sausage |
Suitable Substrates
WATER-BAR XR-2010 may be applied only to:
- Structural reinforced concrete slabs, walls, footings, piles, pile caps, capping beams and similar concrete areas having concrete compressive strength greater than ≥25 MPa
- High strength pipe and conduits composed of corrosion resistant metals, PVC, HDPE, reinforced concrete and fibre reinforced plastics, passing through structural concrete
Substrate Quality
Substrates must be structurally sound, clean and dry to slightly damp.
Reinforced Concrete
- Well compacted, moisture cured as required by AS 3600
- Minimum concrete age = 14-28 days, dependent on concrete thickness, moisture content and primer
- Compressive strength – minimum strength grade 25 MPa to prevent concrete damage by swelling waterstop
Metals
- Free of corrosion, gaps, holes and defects
Plastics
- Clean, dry and free of contaminants
Substrate Preparation
Concrete, Masonry, Screeds and Renders
- Remove all dirt, dust, standing water and contaminants
Metals
- Remove all dirt, dust, contaminants, water and corrosion
Plastics
- Remove all dirt, dust, contaminants and water

Application Equipment
Generally, corrosion resistant concrete nails with flat heads or washers fitted and suitable nail gun.
Application to Smooth Concrete Surfaces
- Unroll the waterstop and mechanically fix centrally in the width of the next concrete pour, maintaining a minimum 75mm concrete cover
- Mechanically fix through the waterstop and into solid concrete using corrosion resistant, flat head concrete nails, or fix with concrete nails and 10mm OD washers
- Mechanically fix at maximum 300mm centres ensuring waterstop lies flat on the substrate. Reduce fixing centres to 200mm or 100mm at direction changes
- Where joining successive rolls or joining to other runs of installed waterstop, products must be side-by-side lapped 100mm
- Once fixed, waterstop must be resistant to displacement by other trades, concrete pour or concrete vibration processes
- Concrete placement may commence immediately after waterstop is correctly fixed
- Placed concrete must be well compacted around WATER-BAR XR-2010 without any voids or honeycombs
Application to Rough / Scabbled Concrete Surfaces
- Waterstop should be located centrally in the width of the next concrete pour, while maintaining a minimum 75mm concrete cover
- Gun a bead of SWELLSEAL Mastic WA hydrophilic mastic to the concrete at this location. Mastic bead must be large enough to fill level all depressions in the rough concrete surface. Typically, a 10mm diameter bead is required
- Unroll the waterstop and lay firmly into the uncured mastic.
- Mechanically fix through the waterstop, mastic and into solid concrete using corrosion resistant, flat head concrete nails, or fix with concrete nails and 10mm OD washers
- Mechanically fix at maximum 300mm centres ensuring waterstop lies flat on the substrate. Reduce fixing centres to 200mm or 100mm at direction changes
- Once fixed, mastic should be visible filling all depressions under the waterstop and have extruded out from both sides of the waterstop profile
- Once fixed, waterstop must be resistant to displacement by other trades, concrete pour or concrete vibration processes
- Concrete placement may commence immediately after waterstop is correctly fixed and before SWELLSEAL Mastic WA has cured firm
- Placed concrete must be well compacted around WATER-BAR XR-2010 without any voids or honeycombs
Application to Pipes and other Penetrations
- Waterstop should be located around the pipe penetration centrally in the concrete thickness
- Wrap the waterstop around the pipe, ensuring ends overlap each other by 100mm
- Fix the waterstop to the pipe using steel or stainless steel tie wire wrapped over the waterstop. Twist wire end firmly to secure
- Alternatively, substitute the WATER-BAR XR-2010 with a continuous 10mm x 10mm bead of SWELLSEAL Mastic WA applied directly to the clean pipe. Allow SWELLSEAL Mastic WA to cure firm a minimum 24 hours before placing concrete
- Placed concrete must be well compacted around WATER-BAR XR-2010 (or SWELLSEAL Mastic WA) without any voids or honeycombs
