At CRW Contracting Ltd we supply and install liquid damp proof membrane systems to protect flooring installations from moisture related failure. Excess moisture within concrete and screeded subfloors can compromise adhesives and floor finishes if left untreated. Our liquid DPM installations create a seamless moisture barrier, allowing flooring projects to proceed safely and with long-term reliability.
What Is a Liquid Damp Proof Membrane?
A liquid damp proof membrane is a surface applied moisture suppression system designed to control residual moisture within concrete and screeded floors. Once applied and fully cured, it forms a continuous, impermeable barrier that prevents moisture rising through the subfloor and affecting the final floor covering.
Liquid DPM systems are commonly used where traditional sheet membranes are absent, damaged, or ineffective, and where moisture readings exceed the acceptable limits for direct floor covering installation. They are suitable for both new build and refurbishment projects.
Our Process
We begin with a detailed assessment of the subfloor, including moisture testing using calibrated equipment to establish relative humidity levels. This allows us to determine whether a liquid damp proof membrane is required and which system is most appropriate for the conditions on site.
The surface is then mechanically prepared to remove contamination such as laitance, adhesives, or weak material and to ensure proper adhesion. The liquid membrane is applied evenly across the floor, typically in multiple coats, to achieve the required level of moisture suppression.
Once cured, the surface is ready to receive primers, latex levelling compounds, or direct floor finishes in line with the project specification.
Precision and Professional Standards
Correct application is critical to the performance of a liquid damp proof membrane. Coverage, thickness and curing times must all be carefully controlled. At CRW Contracting we follow manufacturer guidelines precisely to ensure full protection and consistent results across the entire area.
This attention to detail significantly reduces the risk of future flooring issues such as debonding, blistering or lifting caused by moisture.
