Applications for Pure Polyurea in Public Buildings

Left undetected, maintenance issues associated with water damage can cause permanent structural damage, hefty utility bills and health hazards for occupants. Therefore, ensuring buildings are secure against the risks of water damage is a non-negotiable consideration for facilities managers, project managers and building maintenance managers.

In common areas and public buildings, safety is paramount. Building and facilities managers have a duty of care (and a legal obligation) to ensure public buildings are suitably protected against unexpected hazards.

From roofs and multi-storey car parks to brewery cellars, garage units and warehouses, waterproofing for public buildings is crucial in reducing the cost of maintenance and ensuring public safety.

High-quality waterproofing solutions can prevent structural damage and preserve structural defects, adding valuable longevity and robustness to a structure whilst ensuring public buildings comply with strict safety regulations.

And now that life in the UK is beginning to return to normal, and public buildings are experiencing increased traffic, there is no time like the present when it comes to choosing the right waterproofing solution for your facilities and infrastructure.

Pure polyurea — the ultimate solution

Construction and maintenance managers of public buildings need a high-quality, long-term solution to protect internal and external structures from water damage and avoid having to fork out for maintenance and repair.

Polyurea compounds provide a waterproof, fire-resistant coating for relevant substrates. Several hybrid polyurea products on the market might be cheaper to install initially but will inevitably incur further maintenance costs — or even need replacing completely — down the line.

Not only do these hybrid products produce inferior results, but they are also more sensitive to moisture and temperature variations during the application process. Therefore, they are rendered unsuitable for some applications.

Pure polyurea, on the other hand, provides the ultimate return on investment. This coating is a rubber-like amalgam that is highly flexible, durable and resistant to many external variables — including humidity and moisture.

The chemical credentials of pure polyurea are far superior to that of other membranes, which sacrifice performance and durability in favour of short-term cost-savings. As a result, pure polyurea is the first-choice waterproof coating, providing a one-time-fix solution for large commercial applications.

Considerations for waterproofing public buildings

External features such as building roofs must be reinforced. Roofs are frequently exposed to weather and standing water which can cause structural damage and deformities — and provide an access point for water to permeate the internal structure.

But waterproofing issues do not always appear at the surface level; the root of a problem can often come from within, so it is crucial to ensure foundations and structures are protected during construction and beyond.

Water penetration from moisture buildup or leaks can cause internal temperature changes that disrupt temperature-regulating heating, ventilation and air conditioning (HVAC) systems, contributing to larger utility bills — not to mention the havoc a water leak can wreak on electrical systems.

A buildup of water can also leave metal structures vulnerable to rust, and water or moisture can migrate down through floors during construction in cold, wet months to cause more irreparable damage. Plus, compromised conditions are also ripe for mould to grow, which can cause serious health problems for those who live and work within the area.

Areas like walkways, warehouse floors and sports and leisure facilities are also likely to become slip hazards when wet — but pure polyurea can be mixed with sand to provide added non-slip protection.

What to expect…

That is why construction and maintenance managers of public buildings call on trained waterproofing specialists to apply pure polyurea using the hotspray method for a quick application and fast-curing protective barrier against moisture penetration for almost any surface.

Building maintenance is costly and often highly avoidable when the proper preventative measures are in place.

A waterproofing contractor will initially assess the existing property or area in question for any moisture-related vulnerabilities to determine where reinforcements might be needed. Diagnostics can be performed with thermal imaging technology, which detects water behind walls, ceilings and flooring that cannot be seen with the naked eye.

Equipped with this information, contractors can then begin preparing relevant substrates for coating. Any existing products or substances contaminating a surface can disrupt application and produce sub-par results, so this is an essential part of the process. Although pure polyurea is resistant to moisture and can be used on water-sensitive applications, it is essential to note that this job is sometimes weather-dependent for outdoor applications — for example, when rain might disrupt the crucial preparation of a substrate.

Once the surface is prepped and primed and any cracks or joints are repaired and sealed, the hotspraying can begin. Technicians use specialised application guns to pump chemical components through heated hoses, mixing within the chamber to create a pure polyurea compound coating.

Pure polyurea hotspray is fast-drying and comes with a manufacturer’s guarantee of up to 50 years when applied by an approved technician, making it not only a practical long-term solution but one that requires minimal downtime and maintenance.
