Specification
The defect and the structural intent decide the mortar, not the brand. Five product categories cover almost every concrete repair package on a UAE site, each linked to the brand pages where the technical data sheets live.
Fiber reinforced, high strength mortars for beams, columns and slabs: Mapegrout ME05, Mapegrout ME06 and webertec 306 EHS.
Shrinkage compensated mortars for honeycombing and shallow patching: Planitop 105 ME, Planitop 400 ME and weberep ST.
Primers and passivating coats that treat rusting rebar and bond new mortar to old concrete, from both the Mapei and Weber ranges.
Pourable grouts for voids, anchors and machine base plates: Mapefill GP ME, weberep 350 NSG and webertec grout FG.
Dynamon SX superplasticiser for new concrete pours, and weberanc 405 BFX and weberanc 435 VE chemical anchors for structural fixings.
Spalled concrete usually means the rebar underneath is corroding and expanding, so the steel has to be treated before the patch goes on. Weber pairs a corrosion inhibiting primer with weberep 331 TX thixotropic mortar for overhead and vertical facade repairs, and Mapei follows the same sequence, cleaning and priming exposed rebar before Mapegrout structural mortar goes on. Skipping the rebar step is the most common reason a patch repair fails again within a year.
Not every crack needs the same treatment: a structural crack has to transfer load across the gap, while a crack that only needs sealing can use a simpler resin. Mapei supplies injection resins and grouts for structural crack bonding or waterproofing intent, and the right choice depends on crack width, depth and whether load transfer is required. Weber's fiber reinforced repair mortars add crack resistance where a wider patch is moving under traffic or thermal cycling.
Honeycombed concrete, where the mix has not consolidated around the formwork or reinforcement, leaves voids that trap moisture and weaken the cover. Mapei's non shrink repair mortars, Planitop 105 ME and Planitop 400 ME, are formulated to patch these surface defects without shrinking away from the substrate once they cure. Surface prep, cleaning, roughening and priming, decides whether the patch bonds for the long term.
When a beam, column or slab has to carry load again, not just look repaired, the mortar has to meet engineered strength and bonding requirements rather than a generic patch. Weber's webertec 306 EHS is an extra high strength repair mortar for load bearing structural repairs, and Mapei's structural grade Mapegrout mortars are built to restore sections of beams, columns and slabs. Both ranges are fiber reinforced for the crack resistance that dynamic structural loading needs.
Machinery base plates and anchor bolts need a pourable grout that fills the void completely and does not shrink away as it cures, or the equipment moves out of alignment. Weber's weberep 350 NSG is a non shrink grout made for precision anchoring and machine base plate grouting, and webertec grout FG is the fine grain version for tight spaces. Mapei's Mapefill GP ME is the equivalent pourable, non shrink grout for anchoring and filling voids in Middle East heat.
Once a damaged area is structurally repaired, the floor still has to be brought back flat and fast before the floor covering goes down. Mapei's Topcem Pronto is a quick setting, ready to use binder for fast track screeds that lets floor coverings go down within 24 hours. It is the levelling step that follows a repair, not a replacement for the repair mortar itself.

Buyer's checklist
A patch that fails shows up long after the invoice is paid. These five checks decide whether the repair holds and whether the manufacturer stands behind it.

Repairing concrete over corroding steel leads to repeat failure within a year. Expose the rebar, remove rust and loose concrete, clean the steel, then apply a corrosion inhibiting primer before any Mapegrout or weberep mortar goes on.
A repair mortar that shrinks as it cures pulls away from the substrate, and one weaker than the parent concrete becomes the next point of failure. weberep ST and Mapei's Planitop and Mapegrout mortars are shrinkage compensated and should match or exceed the compressive strength of the concrete around them.
Every quotation comes with the manufacturer's technical data sheet and safety data sheet for each product, plus EN and BS compliance references and submittal support where a consultant needs them.
Fast moving repair mortars, grouts and admixtures 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
A non shrink repair mortar is designed to fill voids and patch surface defects without shrinking away from the substrate as it cures. Mapei's Planitop 105 ME and Planitop 400 ME are formulated this way for cosmetic repairs, honeycombing and shallow patching where structural performance is not the priority, and Weber's weberep ST mortar mixes with water only to the same non shrink, high adhesion result.
Use structural repair mortar when the repair has to carry load or restore structural integrity, such as beam soffits, column corners or slab sections. Mapei's Mapegrout ME05 and Mapegrout ME06 meet higher strength and bonding requirements for exactly this, and Weber's webertec 306 EHS is formulated as an extra high strength mortar for load bearing structural repairs.
Expose the rebar, remove rust and loose concrete, clean the steel thoroughly, then apply a corrosion inhibiting primer before the repair mortar goes on. Skipping this step is the most common reason a patch repair fails again within a year. Both Mapei and Weber supply the primers and passivating coats needed before Mapegrout or weberep mortar is applied.
Repair mortars such as weberep ST are fine aggregate products for surface repairs up to 50 mm deep per layer. Micro concrete such as weberep 311 MC contains coarse aggregate for deep section repairs and void filling, suitable for repairs from 50 mm to over 100 mm per pour.
Weber's weberep epo 410 is a three component fast setting epoxy mortar with exceptional chemical resistance. It resists petroleum, oil, grease, acids, alkalis, solvents and salt water where cementitious mortars would deteriorate, and it bonds to steel, concrete and bricks with high adhesion.
Yes. Weber offers both cementitious and epoxy anchoring grouts. Cementitious grouts such as weberep 350 NSG and webertec grout FG suit static anchors and machine base plates in dry conditions, while epoxy grouts such as weberep epo 410 provide higher strength and chemical resistance for more demanding anchor applications.
