A Kicker Type PVC Water Stopper is a surface (external) type water barrier used in concrete construction joints to prevent water leakage, especially at the junction of slab and wall (kicker joint).

A kicker type water stopper is a flexible PVC strip placed at the base of vertical concrete walls (kicker level) to seal the joint between two concrete pours. 

👉 Unlike embedded water stoppers, it is:

• Installed externally (surface type)

• Used when steel reinforcement prevents embedding 

Kicker type water stoppers are mainly used at critical leakage points, such as:

• Raft slab to wall junction

• Retaining walls

• Basements

• Water tanks & reservoirs

• Swimming pools

• Tunnels & underground structures 

👉 Especially important where water pressure is high at construction joints

• Installed at the joint before concreting

• One side is fixed in the base slab

• The other side gets embedded in the wall concrete

• Creates a continuous waterproof barrier

👉 It blocks water by:

• Increasing seepage path

• Providing tight bonding with concrete using ribs/grooves 

• ✔ High flexibility & elasticity

• ✔ Strong resistance to hydrostatic pressure

• ✔ Resistant to chemicals, salts & corrosion

• ✔ Durable and long life

• ✔ Can handle joint movement (expansion/contraction) 

• Material: PVC (Polyvinyl Chloride)

• Width: 150mm, 230mm, 300mm

• Thickness: 4mm to 5mm

• Length: 15–25 meters roll

• Color: Black / Blue / Yellow 

👉 Kicker type is best when embedding is not possible due to reinforcement congestion 

• Prevents leakage at the most vulnerable joint (kicker joint)

• Easy installation compared to embedded types

• Works under both positive & negative water pressure

• Cost-effective waterproofing solution

1. Fix water stopper at slab edge (kicker level)

2. Secure with clamps or wire

3. Pour slab concrete

4. Embed remaining portion in wall concrete

A Kicker Type PVC Water Stopper is a critical waterproofing product used at slab-to-wall joints. It ensures zero leakage, improves structural durability, and is widely used in civil construction projects involving water retention or underground structures.

A PVC chamfer refers to a beveled edge or angled cut applied to PVC (polyvinyl chloride) materials, typically used in construction, plumbing, and formwork applications. Chamfering PVC can improve aesthetics, facilitate easier fitting, or create smooth transitions between surfaces.

1. Formwork & Concrete Construction:

   • Used in concrete formwork to create beveled edges on columns, beams, and slabs.
   • Helps prevent sharp edges and reduces the risk of chipping.

2. Pipe & Fitting Preparation:

   • Chamfering PVC pipes before joining improves adhesion and ensures a proper seal with solvent cement.
   • Reduces the risk of leakage and simplifies insertion into fittings.
