Description
Groundwater at the kicker joint is the most common leak path in UK basements. Our wholesale PVC waterbar UK for basement waterproofing programme ships BS 8102:2022 compliant strips that seal construction joints under sustained hydrostatic head. Every profile is extruded in-house and cut to your drawings, at source factory pricing with no distributor markup.
What ships with every order:
- Centre bulb, dumbbell, ribbed and rear guard profiles, 150 to 300 mm wide
- 25 m rolls plus factory-fabricated corners, tees and crosses
- A batch mill test certificate covering tensile strength, elongation and hardness
- Mixed-container loading with PVC waterproofing membrane and drainage products
Specifications Matched to UK Project Specs
| Parameter | Specification | Adapted for UK Projects |
| Profile | Centre bulb, dumbbell, ribbed, rear guard | Rear guard on kicker joints, centre bulb on movement joints, following BS 8102:2022 Type B design guidance |
| Width × Thickness | 150–300 mm × 4–10 mm | Metric sizing aligned with UK drawings; 200 mm and 250 mm cover most basement and tank joints |
| Mechanical Properties | Tensile ≥15 MPa, elongation ≥300%, Shore A 65±5 | Values reported per BS EN ISO test methods, formatted for consultant approval |
| Service Temperature | -30 °C to +60 °C | Stays flexible through winter pours and short summer heat peaks |
| Compliance & Packing | BS 8102:2022 Type B compatible; 25 m rolls; batch mill certificates | Documentation structured for NBS clauses and waterproofing designer submittals; roll length matches UK site handling |
For movement joints carrying hydrostatic head, the 250mm centre bulb waterbar BS 8102 Type B is our default recommendation for basement and tank structures.
A note on terminology: UK specifications and the BS 8102 family use waterbar, while US practice says waterstop. Both terms refer to the same cast-in joint sealing strip, and our submittals list both so they fit either consultant convention.
Where Our Waterbars Work Hardest in UK Projects
✅ Residential and commercial basements — buyers: waterproofing specialists, main contractors
Local pain point: damp patches at kicker joints failing BS 8102 Grade 3 requirements at pre-tanking inspection.
Our advantage: engineered as a waterbar for water ingress at basement kicker joints, the rear guard profile fixes to the outside of the first pour with no split-form work, and the 25 m rolls cut field joints by roughly 60% against 10 m strips.
✅ Underground car parks — buyers: structural contractors, basement designers
Local pain point: hydrostatic pressure on raft slab joints peaks in wet winters, long after the pour.
Our advantage: the 200 mm centre bulb profile absorbs seasonal joint movement, while elongation ≥300% tolerates the differential settlement common on soft ground in the Midlands and the North.
✅ Lift pits and sumps — buyers: lift shaft and M&E subcontractors
Local pain point: groundwater concentrates at the lowest point of the structure, where joints are hardest to rework.
Our advantage: rear guard waterbar wraps pile cap and kicker details; combined with PVC waterproofing membrane at construction joints it forms the dual defence many UK waterproofing designers specify for Grade 3 environments.
✅ Pumping stations and flood defence structures — buyers: civil contractors, environment agency frameworks
Local pain point: fluctuating water levels cycle joints open and closed, fatiguing rigid seals.
Our advantage: centre bulb profiles flex with each cycle; drainage runs tie into HDPE double wall corrugated pipe from the same container, keeping one QC file across two scopes.
Profile selection, in short:
- Kicker joint, wall-to-slab, little movement → rear guard or dumbbell profile
- Movement joint under head → centre bulb profile, bulb centred on the joint
- Existing joint already damp → externally fixed rear guard retrofit with sealed splices
Case Study — Two-Level Residential Basement, Greater Manchester
Project: two-level basement, residential development, Greater Manchester
Buyer: a regional main contractor (previously sourcing waterbar through a UK distributor)
Problem: at pre-tanking inspection, damp patches appeared at 26 of 168 kicker joint sections. BS 8102 Grade 3 compliance was at risk, the tanking subcontractor was standing by at cost, and the programme was slipping. The contractor needed a proven waterbar for water ingress at basement kicker joints without recasting the walls.
What we did:
- Supplied 1,450 m of 200 mm rear guard profile with 210 factory-fabricated corners, delivered in 17 days
- Held a remote installation briefing for the waterproofing subcontractor before the first section went in
Before vs. after:
| Metric | Before | After |
| Damp kicker joint sections | 26 of 168 | 0 after remediation and 28-day monitoring |
| Programme position | 12 days behind | Handover 9 days ahead of the revised date |
| Financial exposure | ≈ £42,000 delay and rework costs | Avoided |
| Repeat business | None | 3,200 m follow-up across two further basement packages |
Why Choose Us

FAQ
Q: What is the correct waterbar profile for a basement kicker joint?
A: For a standard wall-to-slab kicker with little movement, a 150–200 mm rear guard profile fixed to the outside of the first pour is the usual choice. If the joint is expected to move, switch to a centre bulb profile. Send your joint drawing and we will confirm the selection within one business day.
Q: How much hydrostatic pressure can a PVC waterbar resist?
A: It depends on width and profile. As a working guide, 200 mm suits heads up to around 10 m and 250 mm to 300 mm suits higher heads, with centre bulb profiles preferred where the joint moves. We confirm the selection against your ground water report.
Q: Can you provide documentation for BS 8102 compliance?
A: Yes. Each shipment is covered by a batch mill test certificate with tensile, elongation and hardness values, plus a compatibility statement for BS 8102:2022 Type B design. For movement joints, the 250mm centre bulb waterbar BS 8102 Type B datasheet sets out the test values your designer will ask for.
