01 / Overview
Moisture: the hidden floor killer
Moisture vapour transmission through concrete slabs is one of the most common — and costly — causes of floor covering failure. Adhesive breakdown, bubbling, delamination and mould growth all stem from moisture migrating up through the slab.
Apex Floor Preparation provides tested moisture control solutions that protect your floor covering investment. We measure, diagnose and treat moisture issues before they become warranty claims and callbacks.
Warning signs
- Adhesive failure under vinyl or carpet
- Bubbling or blistering coatings
- White efflorescence on the surface
- Musty odours or mould growth
- Cupping or warping timber floors
- Discolouration under coverings
02 / Methods
Our moisture control solutions
02.1
Moisture testing
Comprehensive moisture assessment using ASTM F2170 in-situ relative humidity testing and calcium chloride testing (AS 1884), with documented results to show whether mitigation is needed before your floor covering goes down.
| Standards | ASTM F2170 · AS 1884 |
02.2
Vapour barriers
High-performance epoxy vapour barriers that block moisture transmission up to 100% RH. Applied systems rated for the most severe moisture conditions and compatible with all floor covering types.
| Rated | Up to 100% RH |
02.3
Moisture-tolerant primers
Specialist penetrating primers for moderate moisture conditions, keeping moisture within acceptable limits for your floor covering adhesive or coating system.
| For | Moderate moisture |
02.4
Encapsulation systems
Complete encapsulation of contaminated or high-moisture slabs. Multi-layer systems that isolate the floor covering from the substrate, with warranties from the system manufacturer.
