Common questions, in plain language.
-
Why does Tilers Ghana test substrate moisture before installation?
Substrate moisture above specification thresholds compromises adhesive bond integrity within 12-18 months — invisible at handover, costly to remediate later. ASTM F2170 in-situ probe testing is the empire-permanent standard before any Tier-1 institutional commission.
-
What flatness tolerance do large-format installations require?
Large-format porcelain (≥600×600 mm) requires FF35/FL25 substrate flatness per ASTM E1155 — substrate variance beyond this produces visible lippage and joint inconsistency. Tilers Ghana measures and documents F-numbers before commencing installation.
-
What's the difference between rectified-edge and cushion-edge tile?
Rectified-edge tiles have factory-cut precision edges enabling minimal grout joints (1-2mm) and continuous-plane installations — the specification standard for Tier-1 commercial. Cushion-edge tiles have softer edges suited to residential applications with wider grout joints.
-
What slip rating do hotel pool surrounds need?
ISO 14904 R-classification determines slip resistance for wet areas — R11 is the minimum for hotel pool decks, R12-R13 for commercial wet areas with chemical exposure. Tilers Ghana specifies R-rating against project use-class at survey stage.
-
Can damaged heritage encaustic floors actually be restored?
Yes — Tilers Ghana provides forensic survey, replacement-piece commissioning to match species and pattern, and conservation-grade re-laying. Restoration preserves the architectural and cultural value that contemporary replacement erases without recovering.
-
What does the written guarantee cover?
Tilers Ghana issues 5-year Local Performance, 7-year ISO-aligned Extended, or 10-year Industrial Performance guarantees against project classification. Terms are documented in the project handover dossier — no verbal assurances, no ambiguity.
-
How does Tilers Ghana coordinate multi-property hotel rollouts?
Through the multi-property project office model — single specification document, single QC regime, single warranty schedule applied across 3-15 properties under named project leadership. Cost and coordination drag of multiple contractors eliminated.
-
Is the on-site survey actually free?
Yes — every prospective Tilers Ghana commission begins with a free on-site survey including substrate moisture verification, F-number measurement, and ICRI CSP profile assessment. The output is a written specification brief presented before any commercial commitment.
-
What standards does Tilers Ghana installation comply with?
ISO 13006 ceramic tile classification, ASTM C1028 friction, ASTM E1155 floor flatness, ASTM F2170 substrate moisture, ICRI CSP surface profile, ISO 9001 quality management, ISO 14001 environmental, ISO 45001 occupational health & safety. All apply across every commission.
-
How long does a typical premium tile commission take?
Timeline depends on scope and substrate condition. Premium residential master bathroom: 3-6 weeks. Hotel public-space large-format: 8-16 weeks. Multi-property hospitality rollout: 12-24 weeks. Tilers Ghana provides committed timeline at specification brief stage.
-
Where does Tilers Ghana sit on price?
Specification-grade. Tilers Ghana is positioned for Tier-1 institutional clients where installation quality is the multi-decade investment — never the lowest-priced option, never the highest. Budget realism is documented at specification brief stage.
-
Does Tilers Ghana take international commissions?
Yes — Tilers Ghana operates across Ghana, Togo, and the broader francophone West African catchment via Togo representation. Diaspora clients commissioning premium installations within Ghana from Lomé, Cotonou, or Abidjan are equally served.
