polyurethane spray foam & polyurea coatings

About Highgrade Coatings

Polyurethane foam is a high quality versatile insulation that can be sprayed or injected on to most surfaces and in most voids, you can not beat polyurethane foam when it comes to your insulation needs, the R-value is higher then any conventional insulation material and being sprayed on allows for an air tight seal as well as providing a great sound barrier. We have been in the spray foam business in New Zealand for 30 years with vast knowledge and experience.

polyurethane foam

Polyurethane closed cell spray foam is the most efficient container home/storage insulation solution. It will offer the highest insulation value at approximately R-1 Per inch. Spray foam completely covers the surface of the corrugated shipping container walls leaving no gaps between the insulation and the container walls. There is no better moisture/vapour barrier than closed cell spray foam insulation. Do it once and do it right use closed cell spray foam insulation on your container modification!

Polyurea Coatings

Polyurea is a truly remarkable coating, lining and joint sealant technology and can be used for a wide variety of applications. Polyurea coatings and linings are commonly applied over concrete and steel for corrosion protection and abrasion resistance. They also have numerous advantages over conventional materials due to their extremely fast setting times, high elongation, extreme resistance to atmospheric attack and their durability abrasion characteristics.


concrete Level & repair

Raising and levelling large concrete areas like driveways and garage aprons is far more cost-effective than removal and replacement, and offers a permanent solution. Unlike replacement, polyurethane injections will stabilize the underlying soil which concrete replacement alone will not do. Also, the polyurethane concrete repair process can be performed without disrupting the surrounding landscape. Best of all, you can park your vehicles on your driveway again by the time we’ve pulled away!

More Applications for polyurethane foam

Polyurethane has the highest R-value of any cavity insulation and reduced energy costs. It protects against moisture and reduces the chance of harmful mildew. It serves as a noise barrier and reduces sound transfer through a buildings roof, floors and walls, and also creates an air barrier and adds structural strength.
