PU Grouting vs Tile Hacking
PU grouting versus full tile hacking for bathroom leaks: when the no-hack injection method holds, and when only a full membrane replacement will stop the drip.
Key takeaways
Practical guidance for KL & Selangor
Malaysian homes face tropical humidity, fast rain cycles, condo management rules, and mixed construction materials. That means the right method depends on surface condition, access, safety requirements, and whether water or structural movement is involved.
The safest approach is to shortlist the likely cause, collect clear photos, confirm the property type, and request an itemised fixed-price quotation. KL Servis Rumah confirms scope before work begins and avoids arbitrary pricing.

FAQs
Can PU grouting permanently fix a bathroom leak?
For hairline concrete cracks and joint leaks, yes — PU resin expands on contact with water and fills voids that surface sealants cannot reach. But if the waterproof membrane itself has failed, grouting is a temporary patch.
When is tile hacking the only honest answer?
When the membrane under the tiles is torn, delaminated or aged beyond repair — no injection method fixes a membrane that no longer exists, and selling you one is the most common upsell in waterproofing.
How do I know which method my bathroom needs?
A water test that maps the leak pattern, plus inspection of the membrane condition through a removed grout line or access point — honest contractors show you the evidence before recommending either approach.
Does PU grouting come with a warranty?
Typically 1–2 years on the injection work, compared to up to 5 years on a full membrane replacement — the warranty difference reflects the scope, not the contractor's confidence.
