The Attributes of Polyurethane Resin

The versatility of High Pressure Polyurethane Injection (HPPI) is an attribute to the characteristics of quality polyurethane resins used for structural and water prevention systems.

Once activated, polyurethane typically expands to 2.5 times it's volume. This is very desirable when filling large cavities or when the size of a cavity is unknown. The expansive force of polyurethane is significant; consequently it will fill any and all gaps that it encounters. This is particularly useful when dealing with very porous concrete or when dealing with honeycombing. It will also expand wherever it can; following the path of least resistance, it will fill any and all voids encountered.

Our polyurethane resins are non-toxic. This makes them suitable for use with portable water systems such as cisterns. Polyurethane sets rapidly in the presence of hydrogen. Since hydrogen molecules are a component of water (H2o), the presence of water during an injection actually increases the reactivity of the polyurethane. This makes polyurethane the ideal product to use when active basement leaks and/or significant hydro-static pressure, are encountered.

The polyurethane resins that we use will not freeze and always remain flexible (not an attribute of all polyurethane); this is desirable when the concrete surrounding it expands and contracts due to thermal cycling; Polyurethane sets very quickly. This is essential in stopping leaks where significant hydro-static pressure is present. 

At Mfwic Waterproofing Pty Ltd, we use polyurethane resins of varying viscosity; this gives us more flexibility in dealing with cracks the size of a hairline to a large void.
