Control workability, strength and setting time of your concrete

Admixtures are the small dose that changes everything about a concrete pour. The right one lets you cut water content without losing workability, keeps a truck workable through Karachi traffic, or lets a slab take load days earlier than it otherwise would.

We supply the full admixture family and, more importantly, help you pick the right one. Dosage is always trial-mixed against your own cement, sand and aggregate before it goes into a structural pour, because the same admixture behaves differently with different cement.

Supplied to contractors and builders, or supplied and applied by our own teams with a written warranty.

Key Features & Benefits

  • Water reduction without loss of slump, giving higher strength from the same cement content
  • Extended workability for long haul distances and hot-weather concreting
  • Set retarders for mass pours and raft foundations
  • Set accelerators for early formwork stripping and repair work
  • Integral waterproofing admixtures for tanks, basements and retaining walls
  • Chloride-free formulations, safe with reinforced and pre-stressed concrete
  • Site trial mix and dosage optimisation included with supply

Where It Is Used

  • Ready-mix and site-batched structural concrete
  • Raft foundations and mass concrete pours
  • Water-retaining structures such as tanks, sumps and treatment plants
  • Basement rafts and retaining walls
  • Precast elements and pavers
  • Concrete repair and screed mixes

Packaging & Supply

Method

How It Is Applied

The sequence our teams follow, and the sequence we recommend to contractors buying the material from us.

Trial mix

We run a trial with your own cement and aggregate to fix the correct dosage before the pour.

Dispensing

Add to the mixing water, never onto dry cement, using a calibrated dispenser or measured jug.

Mixing

Mix for the full specified cycle after adding, so the admixture disperses completely.

Placing

Place and compact as normal. Slump retention and setting behaviour will follow the trial result.
