How to Choose the Correct Membrane for the Job?

Water can cause buildings to sustain significant damage. If the foundations are not properly waterproofed and secured, this damage will result in substantial financial losses as well as safety concerns. But with the application of waterproofing membranes, it can be avoided. Waterproofing membranes support commercial, industrial and residential properties.

Many contractors prefer spray-applied waterproofing that can help speed up the schedule of projects. In one coat, newer waterproofing technologies spray on and need no reinforcement. The installer sprays the waterproofing solution into the prepared and premiered substrate instead of cutting and placing sheet membranes or cutting and embedding reinforcing fleeces in a liquid waterproofing membrane device. To form one solid membrane, the liquid waterproofing cures. This can also cut days off from installation time for larger projects.

There are several considerations to consider when selecting a spray-applied liquid waterproofing product, in addition to time savings.

Longevity

You would want a solution that has a combination of high tensile strength the force needed to split the specimen or cause complete linear separation of components, the hardness of shore A measure of the hardness of a given material or how resistant it will be to permanent indentation, and elongation the distance from the original size of the membrane to the point at which it will be resistant to permanent indentation.

Bonding ability

You need to make sure that the product binds securely to the type of material you are waterproofing if you are bonding to a substrate. Under the membrane, fully bonded material prevents water from monitoring.

Curing Time

There are several differences in the curing time of various liquid waterproofing membrane solutions. The quicker the recovery time, the better the work can be completed, and the faster the surface is covered from the rain. It takes only seconds to cure certain spray-applied waterproofing solutions, while other hand-applied liquid Waterproof grout sealer will take up to 48 hours to cure, which is not ideal because during that time they are prone to rain.

Many spray-applied solutions often need a primer, and you may want to know not only the waterproofing membrane’s cure time but the primer itself. It takes only two to three hours for some Waterproof grout sealer to recover, while others can take up to 16 hours.

Track Record

There have been liquid waterproofing membrane solutions in use for years. Check that this type of product has a long background with the manufacturer and whether they are accredited installers. Ask them and chat with their sources for some case studies.

UV Stability

The membrane can lose a certain degree of its physical properties when exposed to the heat, with many sheet-applied and liquid-applied waterproofing products, which can cause it to become brittle and crack. Some sheet-applied systems can withstand UV exposure, but they are normally coloured black, allowing heat to be absorbed and making the roof very hot. This puts a strain on the waterproofing membrane and reduces the energy efficiency of the structure. Other solutions are UV stable, but when exposed to the light, they will lose their colour.

To protect the membrane, consider the ideal aesthetics, heat attraction, as well as what roof operation you need. Ask the maker when testing waterproofing products.
