About Xtreme Onsite

Xtreme protective coatings Pty was established in 2001 by Tim and Donna Punch to specialise in the application of polyurea coatings.

Xtreme was one of the first companies in Australia to be able to offer Polyurea coatings to clients demanding the ultimate in coating protection.

Over the years, Xtreme has grown and has established workshops in WA, QLD and NSW.

Our expanding range of services and skilled technicians are able to offer a complete package of specialised skills to repair, restore and protect your assets and infrastructure long into the future.

Our crews are trained to operate safely at height and confined spaces, we pride ourselves on our pro-active attitude to safety and constantly evaluating and assessing risk on the jobsite.

We work closely with our clients and suppliers to develop inspection and test plans to ensure that every repair and application is completed to the highest standard to ensure the longevity and structural integrity of your asset even in the most extreme environments

“Do it right, Do it safely”

Crack injection

Our skilled crew can effectively stop water ingress in underground concrete structures above or below the water table.

We have successfully stopped water ingress in manholes, tunnels, wet-wells, pump stations, holding tanks, reservoirs, bunds and basements. Water ingress, if not addressed, will eventually cause concrete failure and undermine the integrity of the structure

We use high quality hydrophilic and hydrophobic foams, resins and specialist repair mortars to halt water ingress, even if water is flowing. We can then assess and repair any damage that the water infiltration may have caused.

We have successfully and safely sealed many structures while operating in difficult and confined spaces.

Surface preparation

Xtreme onsite provides specialist abrasive blasting services to effectively prepare many different substrates for coatings.

Whether you require metal parts prepared or concrete structures stripped for coating or old failed coatings removed our abrasive blasting service delivers quality results every time.

We operate the latest in wet abrasive blast machines (dust free) and utilise environmentally friendly blast media.
