Concrete Densification

We start by inspecting the floor — checking whether it's a VDF or normal pour, the concrete grade, and the overall surface condition. If seepage was flagged, we test for moisture, and any contaminated or cracked areas are marked out for separate treatment before work begins.

Where old or damaged concrete needs to be broken out, this is done as a dedicated stage before grinding starts. It's only carried out if it's part of IndigoInd's agreed scope, and is priced and scheduled separately from the main floor work.

Hairline cracks are routed out and filled with a rigid epoxy/PU repair compound. Larger structural cracks or spalled patches are repaired as recommended by the site engineer. These repairs are given time to cure fully before grinding starts.

The grinding pass opens up the concrete surface, removes any existing coating, and brings the floor to a uniform plane. On VDF floors this step is lighter since the surface is already denser. Oil-contaminated patches are ground deeper to fully clear the contamination, and high spots or trowel marks are levelled at this stage. Grinding stops at cream level — no aggregate exposure unless specified.

Once the surface is clean and dust-free, we apply a chemical densifier across the whole floor. This soaks into the concrete and hardens it from within, which is what gives the finished floor its strength and resistance to future dust release. Excess product is squeegeed off, and a second coat is applied only where the surface has absorbed more than usual.

If control joints are required, we saw-cut them at the agreed layout after the densifier has cured.

If line marking is needed — traffic lanes, racking bays, safety zones — it's applied to your agreed layout and colour, timed before or after the sealer coat depending on your preference.

If a clear or coloured sealer has been specified, it's applied in thin, even coats and given full time to cure before the floor takes any foot or vehicle traffic. If a densifier-only finish was agreed, this step is skipped.

All grinding is done with continuous dust extraction to keep the site clean while we work. If Strict dust control was requested, we use full containment barriers and negative-pressure extraction, and agree working hours with you in advance.

Before handover, we walk the floor to check surface uniformity, edge finish, and the quality of any joints or line marking against what was agreed. The finished floor is photo-documented, and any areas worth flagging are pointed out to you at handover.
