LAMPOSILEX ME – ULTRA-FAST SETTING HYDRAULIC BINDER FOR INSTANT WATER PLUGGING
Mapei Lamposilex ME – Ultra-Fast Setting Hydraulic Binder for Instant Water Plugging | Nairobi, Kenya
Price: KES 3,500 (Inclusive of VAT) Brand: Mapei (Italy) | Authorized Startcore Ventures Distribution Category: Construction Chemicals / Waterproofing Pack Size: 5kg Drum | Color: Grey | Availability: In Stock
Product Overview
If you're dealing with an active water leak in Nairobi, Mombasa, or anywhere with a high water table, Mapei Lamposilex ME is the professional-grade solution engineers and contractors reach for. This is a ready-mixed, ultra-fast setting hydraulic binder engineered to stop flowing water instantly — even water under active hydrostatic pressure — where ordinary mortars simply get washed away before they can set.
Developed in Mapei's own research laboratories, Lamposilex ME sets in as little as 1.5 to 2 minutes at standard temperature, transforming from powder into a plastic, moldable paste that can be hand-packed directly into a leaking crack or hole to form an instant, permanent, waterproof seal.
At KES 3,500 per 5kg drum, inclusive of VAT, Startcore Ventures Limited supplies genuine Mapei Lamposilex ME as an authorized dealer — critical for emergency waterproofing work, where a counterfeit or diluted product failing mid-repair can mean far more damage and cost than the product itself.
Why This Product Matters for Kenyan Construction Sites
Active water ingress is one of the most disruptive problems on a construction or maintenance site — it can halt work, damage structural elements, and in below-grade structures, worsen rapidly if not addressed immediately. Lamposilex ME is specifically built for this emergency scenario, not as a general-purpose sealant:
- Stops flowing, pressurized water in seconds — not hours
- Expands slightly as it cures, creating a mechanical seal that resists water pressure rather than just a surface patch
- Chloride-free, so it won't promote corrosion of reinforcing steel in concrete structures
- Thixotropic paste consistency — stays in place on vertical or overhead surfaces without formwork
Key Applications
- Basement and below-grade walls — instantly stopping seepage through cracks in walls or floor slabs
- Tunnels and underground utility structures — rapid repair of active water ingress
- Lift pits — sealing leaks before final waterproofing is applied
- Water tanks — stopping leaks in above-ground and underground concrete storage tanks
- Sewers, canals, and drainage systems — watertight sealing of joints, cracks, and holes
- Swimming pools — emergency leak repair ahead of professional resurfacing
- General maintenance — rigid joint sealing and surface reinstatement in damp brickwork before secondary waterproofing

How to Apply Lamposilex ME
Because of the ultra-fast setting time, speed and preparation are critical:
- Enlarge the leak — chisel the crack or hole into a dovetail shape (wider on the inside) so the plug anchors mechanically once cured.
- Clean the cavity — minimum 2cm width and depth, free of loose material and dust.
- Saturate with water — the cavity should be fully wet with no standing surface water.
- Mix small batches only — 2.5 parts powder to 1 part water, mixed vigorously to a smooth paste. Only mix what you can use within one minute.
- Mold and apply — shape the paste into a cone by hand, wait a few seconds until it begins to stiffen, then force it firmly into the crack.
- Hold pressure for 2–3 minutes until fully set.
- Finish by removing excess material with a sandpaper disk or abrasive wheel once cured.
- Work top to bottom if sealing multiple leaks in the same structure.
Frequently Asked Questions
How fast does Lamposilex ME actually set? Initial setting time is 1.5 to 2 minutes at +20°C, which is what allows it to stop actively flowing water before it washes the material away.
Can it stop water under pressure, or only slow leaks? It's specifically formulated for active leaks under hydrostatic pressure, not just damp seepage — this is its primary use case.
Will it corrode reinforcing steel in concrete? No. Lamposilex ME is chloride-free, so it's safe for use in and around reinforced concrete structures.
How much do I need for my repair? Consumption is approximately 1.8kg of powder per liter of cavity volume. A single 5kg drum fills roughly 2.7 liters of cavity.
Can I use this on vertical walls or overhead ceilings? Yes. Its thixotropic paste consistency allows it to stay in place on vertical and overhead surfaces without formwork or shuttering.
Is this a permanent repair or a temporary fix? Once cured, it forms a permanent, waterproof seal. For large-scale or structural waterproofing, it's typically used to stop the active leak first, followed by a secondary waterproofing layer such as Mapei Mapelastic Smart or Idrosilex Pronto over the full surface.
Where can I buy genuine Mapei Lamposilex ME in Kenya? Startcore Ventures Limited, based at Bhavesh Centre, Ngara Road, Nairobi, is an authorized Mapei dealer stocking Lamposilex ME and the full Mapei waterproofing and repair range, with countrywide delivery available.
