Specification
Water pressure, substrate, movement and finish decide the membrane, not the brand. Seven areas cover almost every waterproofing package on a UAE site, each linked to the brand pages where the technical data sheets live.
Two component polymer modified coatings for under tile wet areas, basements and tanks: Mapelastic Smart, Planiseal 88, weberdry 116 FX, weberdry 130 PR and HYDRO BAN Cementitious.
Single and two component liquid polyurethane for terraces, balconies and exposed roofs: Purtop Easy, Purtop 500N, weberdry 360 PU and weberdry 365 MPU.
Ready to use brush or roller membranes for bathrooms, showers and roofs: Laticrete HYDRO BAN, Mapelastic Aquadefense Zero, Mapelastic Easy and Aquaflex Roof HR.
HYDRO BAN Sheet Membrane for steam rooms and vapour control, Weber BIRAP PL torch applied bituminous sheet, weberdry RBE and weberdry prime SB for foundations.
Kerakoll Aquastop Nanoflex, Aquastop Flex and Aquastop Extreme block liquid water while letting vapour escape, and can be applied over existing tiles.
Bathrooms, showers, kitchens and utility rooms need a seamless membrane under the tiles, with the wall to floor joint, drains and pipe penetrations detailed before any adhesive goes down. Mapelastic Aquadefense Zero and Mapelastic Easy are ready to use liquid membranes for this, Laticrete HYDRO BAN cures to a 0.5 to 0.8 mm load bearing film that can be flood tested after 2 hours, and weberdry cementitious coatings and Kerakoll Aquastop give the same protection in mineral form.
Movement and thermal cycling make balconies and terraces the most common place for cracked tiles and seepage into the slab below. Mapelastic Smart and Purtop Easy bridge cracks under tiles or exposed, Kerakoll Aquastop Flex is the two component system for terraces and pools, and HYDRO BAN XP covers exterior tiled surfaces in UAE heat.
Exposed roofs need a continuous, UV stable barrier that carries up and over the parapet, with slope and drainage planned before the first coat. Aquaflex Roof HR and Purtop 500N from Mapei and weberdry 360 PU and weberdry roof from Weber are liquid applied roof membranes, and Weber BIRAP PL is the torch applied bituminous sheet for roofs and foundations.
Below grade walls and foundations face groundwater pushing from behind the membrane, so the coating has to resist negative as well as positive hydrostatic pressure. weberdry 130 PR is Weber's cement based tanking coating for exactly this, weberdry RBE is the rubberised bitumen protective coat for foundation walls, and Planiseal 88 is Mapei's two component cementitious mortar for basements, foundations and tanks.
Pools and fountains mean permanent submersion and chlorine, so a standard wet area membrane is the wrong product. Laticrete HYDRO BAN XP is formulated for permanent submersion, Kerakoll Aquastop Nanoflex is anti alkali and chlorine resistant, and Mapelastic Smart is indicated for basins, swimming pools and wet areas.
Drinking water tanks, reservoirs and cisterns can only be coated with a product certified for potable water contact. Weber documents weberdry 110 FX for exactly that use, a two component polymer modified cementitious coating that also resists positive and negative pressure. Tell us the tank holds drinking water when you enquire and we quote the certified system only.
Where demolition is not an option, some membranes bond directly to sound existing ceramic and marble. Kerakoll Aquastop systems are designed to be applied over existing dimensionally stable tiles, and Laticrete HYDRO BAN bonds to properly prepared existing tile with a thin profile that keeps floor heights down, with HYDRO BARRIER Plus adding crack isolation for renovation substrates.

Buyer's checklist
A leak shows up long after the invoice is paid. These five checks decide whether the membrane performs and whether the manufacturer stands behind it.
Lapiz Blue buys Mapei, Laticrete, Weber and Kerakoll waterproofing directly from the manufacturer or its regional company, so every pail and bag is genuine and batch traceable. The Mapei authorization certificate is published on the About page.
A membrane only performs with a compatible primer, tape and adhesive on top of it. We supply the matching tile adhesive and grout from the same brand, so there is one documented system and one manufacturer behind the whole build up.
Ask how soon the membrane can be flood tested and tiled. Laticrete HYDRO BAN can be flood tested after 2 hours at 21°C and turns dark green when ready, weberdry 110 FX typically needs 24 to 48 hours before adhesive, and the TDS states the figure for every other product.
Every quotation comes with the manufacturer's technical data sheet and safety data sheet for each product, plus submittal support for consultant approval where a project needs it.
Fast moving membranes are held in Al Quoz, Mussafah and Al Sajaa. Orders placed before 3 pm are delivered the next working day across Dubai, Abu Dhabi and Sharjah, and stock lines can be collected the same day.
Questions contractors ask
For bathrooms and showers in Dubai, use a seamless under tile membrane applied before the adhesive, with the wall to floor joint, drain and pipe penetrations detailed. Lapiz Blue supplies Mapei Mapelastic Aquadefense Zero and Mapelastic Easy as ready to use liquid membranes, Laticrete HYDRO BAN as a thin load bearing liquid rubber membrane that can be flood tested after 2 hours, and Weber weberdry and Kerakoll Aquastop cementitious options, all with the matching tile adhesive from the same brand.
Yes, with the right product. Kerakoll Aquastop membranes can be applied directly over existing dimensionally stable ceramic and marble tiles, removing the need for demolition, and Laticrete HYDRO BAN bonds to properly prepared existing tile with a 0.5 to 0.8 mm profile that keeps floor heights down. The existing tiles must be sound and clean, and the TDS for each product states the preparation required.
It depends on the product and site conditions, and the technical data sheet is the reference. Weber states that weberdry 110 FX should cure fully, typically 24 to 48 hours depending on conditions, before tile adhesive is applied. Laticrete HYDRO BAN liquid membrane can be flood tested after 2 hours at 21°C and turns dark green when it is ready for tiling. Lapiz Blue sends the TDS with every quotation so the programme can be planned around the real figure.
Yes. Lapiz Blue General Trading LLC is an authorized Mapei distributor in the UAE, and the Mapei authorization certificate is published on the About page. Mapei waterproofing products such as Mapelastic Smart, Mapelastic Aquadefense Zero, Purtop Easy, Aquaflex Roof HR and Planiseal 88 are supplied with batch traceability and the official Mapei technical data sheets from the Dubai, Abu Dhabi and Sharjah branches.
Swimming pools need a membrane formulated for permanent submersion and chlorine, not a standard wet area product. Lapiz Blue supplies Laticrete HYDRO BAN XP for pools, fountains and spas, Kerakoll Aquastop Nanoflex, which is anti alkali and chlorine resistant, and Mapei Mapelastic Smart, which is indicated for basins, swimming pools and wet areas.
Only a product certified for potable water contact. Weber documents weberdry 110 FX as certified for contact with drinking water, so it is the system Lapiz Blue quotes for potable water tanks, reservoirs and cisterns. It is a two component polymer modified cementitious coating that also resists positive and negative hydrostatic pressure, which suits below grade tanks.
Cementitious membranes such as weberdry 116 FX, Mapelastic Smart and Planiseal 88 bond to concrete and masonry and are the usual choice under tiles, in basements and in tanks. Polyurethane membranes such as Mapei Purtop Easy and Weber weberdry 360 PU bond to a wider range of substrates, stay highly elastic and bridge cracks, and are used exposed on terraces, balconies and flat roofs where UV resistance matters. Lapiz Blue stocks both and confirms the right type for the substrate, finish and exposure.
Yes. Lapiz Blue holds waterproofing stock in three distribution centres, at Al Quoz Industrial Area 4 in Dubai, Mussafah Industrial Area 40 in Abu Dhabi and Al Sajaa Industrial Area in Sharjah, and delivers to all seven Emirates. Orders placed before 3 pm are delivered the next working day in Dubai, Abu Dhabi and Sharjah, and stock lines can be collected the same day.
WhatsApp the area type, substrate, finish and square metres, or the bill of quantities, and the Dubai team replies with the right system, pricing, stock and data sheets the same working day.
Waterproofing is one of eight product families from Lapiz Blue General Trading LLC, the construction chemicals distributor in Dubai behind tile adhesives, repair mortars, screeds, flooring and sealants for the same sites. Application is handled by our sister company Sixty Newton Technical Services.
