MasterSeal 911 is a one component adhesive,based on a modified silane polymer used tosecure the MasterSeal 910 swelling gasket to allcommon substrates in construction.FEATURES Adheres the gasket on plane and roughsurface. Excellent tack on dry and humid surface. Hardened adhesive remains highly flexible inhumid and wet environment.

MasterSeal 910 Waterbar is suitable for allconstruction joints subject to hydrostatic pressure,on one or both sides. MasterSeal 910 providesimple but efficient waterproofing of constructionjoints. Movements in the joint, e.g. by shrinkage orsettlement in the substrate, are taken up by theelastic profile of the MasterSeal 910 Waterbar.MasterSeal 910 has been successfully employedto waterproof joints where an opening of up to5mm was deliberately created. Water pressure ofup to 5 bar was sealed.MasterSeal 910 is based on a newly developedpolymer technology providing flexible polymercomposites which have high chemical resistancecapable of storing water in their molecularstructure by increasing their volume.Where previously MasterSeal 910 was availablein different grades for various exposure conditions.A single version of MasterSeal 910 now resistsdeterioration in the following conditions: In freshwater and where the water has a high salt content(sea water, brackish water), in construction withhigh chemical exposure and/or exposure ofsolvents, including oils and fuels.MasterSeal 910 is a component of the MasterBuilders Solutions pile-cap waterproofing andwatertight jointing systems.

 91 000 74051 A Swellable Water Bar is a flexible hydrophilic strip used for waterproofing construction joints and cold joints in concrete structures. When it comes into contact with water, it swells up to many times its original volume, blocking water passage and sealing the joint effectively.
It is an ideal alternative to conventional PVC water stops for difficult placements, vertical joints, and complex shapes.
Key Features & Benefits
 Hydrophilic swelling action – Expands up to 200–300% on contact with water, sealing gaps. Easy installation – Can be nailed, stapled, or fixed with adhesive in construction joints. Excellent water sealing – Prevents leakage through joints and honeycombs. Durable & chemical resistant – Resists saline water, mild acids & alkalis. Flexible & adaptable – Suitable for irregular profiles, penetrations, and difficult joint shapes. Cost effective – Replaces large PVC water stops in many applications.
Areas of ApplicationWater tanks, underground sumpsSewage treatment plants, STPs & ETPsTunnels & metro structuresBasements, raft slabs, retaining wallsDams, canals, culverts, bridgesPrecast segments & segmental liningsPipe penetrations & concrete joints
Method of ApplicationSurface Preparation: Clean joint surface free of dust, oil, and laitance.Fixing: Place water bar in center of joint using nails, adhesive, or holder.Overlap: Ensure overlaps are minimum 50 mm, press firmly to avoid gaps.Concrete Placement: Pour concrete carefully without displacing the water bar.Curing: Allow concrete to set; upon water exposure, the strip swells to seal joints.
FAQ (Questions & Answers)Q1. What is a swellable water bar used for?It is used in construction joints (horizontal & vertical) to prevent water seepage.Q2. How does it work?It swells on contact with water, blocking water pathways through joints.Q3. Can it be used instead of PVC water stops?Yes. Especially suitable where PVC water stops are difficult to fix, like vertical joints, small widths, and repair jobs.Q4. What sizes are available?Common sizes are 25 × 10 mm, 20 × 15 mm, 25 × 20 mm, etc. Custom sizes are also available.Q5. What is the swelling capacity?Typically 200–300% of its volume depending on grade and water quality.Q6. How to install it?It is fixed with nails, adhesives, or concrete nails in the joint before pouring concrete.Q7. What is the price?Average market price is around ₹200 – ₹350 per meter depending on size, brand, and quality.
